6	Economic Regulation of Distribution Services
Part A	Introduction
6.1	Introduction to Chapter 6
6.1.1	AER's regulatory responsibility
The AER is responsible, in accordance with this Chapter, for the economic regulation of distribution services provided by means of, or in connection with, distribution systems that form part of the national grid.
6.1.1A	[Deleted]

6.1.3	Access to direct control services and negotiated distribution services
(a)	Subject to and in accordance with the Rules:
(1)	a person (a Service Applicant) may apply to a Distribution Network Service Provider for provision of direct control services or negotiated distribution services;
(2)	a Distribution Network Service Provider must provide direct control services or negotiated distribution services (as the case may be) on terms and conditions of access as determined under Chapters 4, 5, this Chapter 6 and Chapter 7 of the Rules.
(b)	The terms and conditions of access are:
(1)	in relation to negotiated distribution services:
(i)	the price of those services (including, if relevant, access charges); and
(ii)	other terms and conditions for the provision of those services;
(2)	in relation to direct control services:
(i)	the price of those services under the approved pricing proposal; and
(ii)	other terms and conditions for the provision of those services.
6.1.4	Prohibition of DUOS charges for the export of energy
(a)	A Distribution Network Service Provider must not charge a Distribution Network User distribution use of system charges for the export of electricity generated by the user into the distribution network.
(b)	This does not, however, preclude charges for the provision of connection services.
Part B	Classification of Distribution Services and Distribution Determinations
6.2	Classification
6.2.1	Classification of distribution services
(a)	The AER may classify a distribution service to be provided by a Distribution Network Service Provider as:
(1)	a direct control service; or
(2)	a negotiated distribution service.
Note
If the AER decides against classifying a distribution service, the service is, subject to Chapter 5A, not regulated under the Rules.
(b)	The AER may group distribution services together for the purpose of classification and, if it does so, a single classification made for the group applies to each service comprised in the group as if it had been separately classified.
(c)	The AER must, in classifying a distribution service or distribution services, have regard to:
(1)	the form of regulation factors; and
(2)	the form of regulation (if any) previously applicable to the relevant service or services and, in particular, any previous classification under the present system of classification or under the previous regulatory system (as the case requires); and
(3)	the desirability of consistency in the form of regulation for similar services (both within and beyond the relevant jurisdiction); and
(4)	any other relevant factor.
(d)	In classifying distribution services that have previously been subject to regulation under the present or earlier legislation, the AER must act on the basis that, unless a different classification is clearly more appropriate:
(1)	there should be no departure from a previous classification (if the services have been previously classified); and
(2)	if there has been no previous classification – the classification should be consistent with the previously applicable regulatory approach.
(e)	If the Rules, however, require that a particular classification be assigned to a distribution service of a specified kind, a distribution service of the relevant kind is to be classified in accordance with that requirement.
6.2.2	Classification of direct control services as standard control services or alternative control services
(a)	Direct control services are to be further divided into 2 subclasses:
(1)	standard control services; and
(2)	alternative control services.
(b)	The AER may group direct control services together for the purpose of classification and, if it does so, a single classification made for the group applies to each service comprised in the group as if it had been separately classified.
(c)	The AER must, in classifying a direct control service as a standard control service or an alternative control service, have regard to:
(1)	the potential for development of competition in the relevant market and how the classification might influence that potential; and
(2)	the possible effects of the classification on administrative costs of the AER, the Distribution Network Service Provider and users or potential users; and
(3)	the regulatory approach (if any) applicable to the relevant service immediately before the commencement of the distribution determination for which the classification is made; and
(4)	the desirability of a consistent regulatory approach to similar services (both within and beyond the relevant jurisdiction); and
(5)	the extent the costs of providing the relevant service are directly attributable to the person to whom the service is provided; and
Example:
In circumstances where a service is provided to a small number of identifiable customers on a discretionary or infrequent basis, and costs can be directly attributed to those customers, it may be more appropriate to classify the service as an alternative control service than as a standard control service.
(6)	any other relevant factor.
(d)	In classifying direct control services that have previously been subject to regulation under the present or earlier legislation, the AER must act on the basis that, unless a different classification is clearly more appropriate:
(1)	there should be no departure from a previous classification (if the services have been previously classified); and
(2)	if there has been no previous classification – the classification should be consistent with the previously applicable regulatory approach.
(e)	If the Rules, however, require that a direct control service of a specified kind be classified either as a standard control service or as an alternative control service, a direct control service of the relevant kind is to be classified in accordance with that requirement.
6.2.3	Term for which classification operates
A classification forms part of a distribution determination and operates for the regulatory control period for which the distribution determination is made.
Note:
The classification is to be reviewed in the course of the making of the next distribution determination, and (subject to these Rules) a reclassification may be made for the purposes of that determination.
6.2.4	Duty of AER to make distribution determinations
(a)	The AER must make a distribution determination for each Distribution Network Service Provider.
(b)	When the AER makes a distribution determination it must follow the process set out in Part E.
(c)	If more than one distribution system is owned, controlled or operated by a Distribution Network Service Provider, then, unless the AER otherwise determines, a separate distribution determination is to be made for each distribution system.
(d)	If 2 or more parts of the same distribution system were separately regulated at the commencement of this Chapter, then, unless the AER otherwise determines, a separate distribution determination is to be made for each of those parts of the distribution system.
6.2.5	Control mechanisms for direct control services
(a)	A distribution determination is to impose controls over the prices of direct control services, the revenue to be derived from direct control services or both.
(b)	The control mechanism may consist of:
(1)	a schedule of fixed prices;
(2)	caps on the prices of individual services;
(3)	caps on the revenue to be derived from a particular combination of services;
(4)	tariff basket price control;
(5)	revenue yield control; or
(6)	a combination of any of the above.
(c)	In deciding on a control mechanism for standard control services, the AER must have regard to:
(1)	the need for efficient tariff structures; and
(2)	the possible effects of the control mechanism on administrative costs of the AER, the Distribution Network Service Provider and users or potential users; and
(3)	the regulatory arrangements (if any) applicable to the relevant service immediately before the commencement of the distribution determination; and
(4)	the desirability of consistency between regulatory arrangements for similar services (both within and beyond the relevant jurisdiction); and
(5)	any other relevant factor.
(d)	In deciding on a control mechanism for alternative control services, the AER must have regard to:
(1)	the potential for development of competition in the relevant market and how the control mechanism might influence that potential; and
(2)	the possible effects of the control mechanism on administrative costs of the AER, the Distribution Network Service Provider and users or potential users; and
(3)	the regulatory arrangements (if any) applicable to the relevant service immediately before the commencement of the distribution determination; and
(4)	the desirability of consistency between regulatory arrangements for similar services (both within and beyond the relevant jurisdiction); and
(5)	any other relevant factor.
6.2.6	Basis of control mechanisms for direct control services
(a)	For standard control services, the control mechanism must be of the prospective CPI minus X form, or some incentive-based variant of the prospective CPI minus X form, in accordance with Part C.
(b)	For alternative control services, the control mechanism must have a basis stated in the distribution determination.
(c)	The control mechanism for alternative control services may (but need not) utilise elements of Part C (with or without modification).
Examples:
The control mechanism might be based on the building block approach.
The distribution determination might provide for the application of clause 6.6.1 to pass through events with necessary adaptations and specified modifications.
6.2.7	Negotiated distribution services
Negotiated distribution services are regulated in accordance with Part D.
6.2.8	Guidelines
(a)	The AER: 
(1)	must make and publish the Shared Asset Guidelines, the Capital Expenditure Incentive Guidelines, the Rate of Return Guidelines, the Expenditure Forecast Assessment Guidelines, the Distribution Confidentiality Guidelines and the Cost Allocation Guidelines in accordance with these Rules; and
(2)	may, in accordance with the distribution consultation procedures, make and publish guidelines as to any other matters relevant to this Chapter. 
(b)	A guideline may relate to a specified Distribution Network Service Provider or Distribution Network Service Providers of a specified class.
(c)	Except as otherwise provided in this Chapter, a guideline is not mandatory (and so does not bind the AER or anyone else) but, if the AER makes a distribution determination that is not in accordance with the guideline, the AER must state, in its reasons for the distribution determination, the reasons for departing from the guideline.
(d)	If a guideline indicates that there may be a change of regulatory approach in future distribution determinations, the guideline should also (if practicable) indicate how transitional issues are to be dealt with. 
(e)	Subject to paragraph (f), the AER may, from time to time and in accordance with the distribution consultation procedures, amend or replace a guideline.
(f)	The AER may make administrative or minor amendments to any guideline without complying with the distribution consultation procedures.
(g)	This clause 6.2.8 does not apply to the Distribution Ring-Fencing Guidelines or the Distribution Reliability Measures Guidelines.
Part C	Building Block Determinations for standard control services
6.3	Building block determinations
6.3.1	Introduction
(a)	A building block determination is a component of a distribution determination.
(b)	The procedure and approach for the making of a building block determination is contained in Part E of this Chapter and involves the submission of a building block proposal to the AER by the Distribution Network Service Provider.
(c)	The building block proposal:
(1)	must be prepared in accordance with the post-tax revenue model and other relevant requirements of this Part;
(2)	must comply with the requirements of, and must contain or be accompanied by the information required by, any relevant regulatory information instrument; and
(3)	must be prepared in accordance with Schedule 6.1.
6.3.2	Contents of building block determination
(a)	A building block determination for a Distribution Network Service Provider is to specify, for a regulatory control period, the following matters:
(1)	the Distribution Network Service Provider's annual revenue requirement for each regulatory year of the regulatory control period;
(2)	appropriate methods for the indexation of the regulatory asset base;
(3)	how any applicable efficiency benefit sharing scheme, capital expenditure sharing scheme, service target performance incentive scheme, demand management incentive scheme, demand management innovation allowance mechanismor small-scale incentive scheme is to apply to the Distribution Network Service Provider;
(4)	the commencement and length of the regulatory control period; and
(5)	any other amounts, values or inputs on which the building block determination is based (differentiating between those contained in, or inferred from, the Distribution Network Service Provider's building block proposal and those based on the AER's own estimates or assumptions).
(b)	A regulatory control period must be not less than 5 regulatory years.
6.4	Post-tax revenue model
6.4.1	Preparation, publication and amendment of post-tax revenue model
(a)	The AER must, in accordance with the distribution consultation procedures, prepare and publish a post-tax revenue model.
(b)	The AER may, from time to time and in accordance with the distribution consultation procedures, amend or replace the post-tax revenue model.
(c)	The AER must develop and publish the first post-tax revenue model within 6 months after the commencement of this clause and there must be such a model in force at all times after that date.
6.4.2	Contents of post-tax revenue model
(a)	The post-tax revenue model must set out the manner in which the Distribution Network Service Provider's annual revenue requirement for each regulatory year of a regulatory control period is to be calculated.
(b)	The contents of the post-tax revenue model must include (but are not limited to):
(1)	a method that the AER determines is likely to result in the best estimates of expected inflation; and
(2)	the timing assumptions and associated discount rates that are to apply in relation to the calculation of the building blocks referred to in clause 6.4.3; and
(3)	the manner in which working capital is to be treated; and
(4)	the manner in which the estimated cost of corporate income tax is to be calculated.
6.4.3	Building block approach
(a)	Building blocks generally
The annual revenue requirement for a Distribution Network Service Provider for each regulatory year of a regulatory control period must be determined using a building block approach, under which the building blocks are:
(1)	indexation of the regulatory asset base – see paragraph (b)(1);
(2)	a return on capital for that year – see paragraph (b)(2);
(3)	the depreciation for that year – see paragraph (b)(3);
(4)	the estimated cost of corporate income tax of the Distribution Network Service Provider for that year – see paragraph (b)(4);
(5)	the revenue increments or decrements (if any) for that year arising from the application of any efficiency benefit sharing scheme, capital expenditure sharing scheme, service target performance incentive scheme, demand management incentive scheme, demand management innovation allowance mechanism or small-scale incentive scheme – see subparagraph (b)(5);
(6)	the other revenue increments or decrements (if any) for that year arising from the application of a control mechanism in the previous regulatory control period – see paragraph (b)(6);
(6A)	the revenue decrements (if any) for that year arising from the use of assets that provide standard control services to provide certain other services – see subparagraph (b)(6A); and
(7)	the forecast operating expenditure for that year – see paragraph (b)(7).
(b)	Details of the building blocks
For the purposes of paragraph (a):
(1)	for indexation of the regulatory asset base:
(i)	the regulatory asset base is calculated in accordance with clause 6.5.1 and schedule 6.2; and
(ii)	the building block comprises a negative adjustment equal to the amount referred to in clause S6.2.3(c)(4) for that year; and
(2)	the return on capital is calculated in accordance with clause 6.5.2;
(3)	the depreciation is calculated in accordance with clause 6.5.5;
(4)	the estimated cost of corporate income tax is determined in accordance with clause 6.5.3;
(5)	the revenue increments or decrements referred to in subparagraph (a)(5) are those that arise as a result of the operation of an applicable efficiency benefit sharing scheme, capital expenditure sharing scheme, service target performance incentive scheme, demand management incentive scheme, demand management innovation allowance mechanism or small-scale incentive scheme as referred to in clauses 6.5.8, 6.5.8A, 6.6.2, 6.6.3, 6.6.3A and 6.6.4;
(6)	the other revenue increments or decrements referred to in paragraph (a)(6) are those that are to be carried forward to the current regulatory control period as a result of the application of a control mechanism in the previous regulatory control period and are apportioned to the relevant year under the distribution determination for the current regulatory control period;
(6A)	the revenue decrements (if any) referred to in paragraph (a)(6A) are those that are determined by the AER under clause 6.4.4 as a result of assets that provide standard control services being used to provide:
(i)	distribution services that are not classified under clause 6.2.1; or 
(ii)	services that are neither distribution services nor services that are provided by means of, or in connection with, dual function assets; and
(7)	the forecast operating expenditure for the year is the forecast operating expenditure as accepted or substituted by the AER in accordance with clause 6.5.6.
6.4.4	Shared assets
(a)	Where an asset is used to provide both standard control services and either:
(1)	distribution services that are not classified under clause 6.2.1; or
(2)	services that are neither:
(i)	distribution services; nor
(ii)	services that are provided by means of, or in connection with, dual function assets that are owned, operated or controlled by the Distribution Network Service Provider,
the AER may, in a distribution determination for a regulatory control period, reduce the annual revenue requirement for that Distribution Network Service Provider for a regulatory year in that regulatory control period by such amount as it considers reasonable to reflect such part of the costs of that asset as the Distribution Network Service Provider is recovering through charging for the provision of a service referred to in subparagraph (1) or (2).
(b)	In making a decision under paragraph (a), the AER must have regard to the shared asset principles and the Shared Asset Guidelines.
(c)	The shared asset principles are as follows:
(1)	the Distribution Network Service Provider should be encouraged to use assets that provide standard control services for the provision of other kinds of services where that use is efficient and does not materially prejudice the provision of those services;
(2)	a shared asset cost reduction should not be dependent on the Distribution Network Service Provider deriving a positive commercial outcome from the use of the asset other than for standard control services;
(3)	a shared asset cost reduction should be applied where the use of the asset other than for standard control services is material;
(4)	regard should be had to the manner in which costs have been recovered or revenues reduced in respect of the relevant asset in the past and the reasons for adopting that manner of recovery or reduction;
(5)	a shared asset cost reduction should be compatible with the Cost Allocation Principles and Cost Allocation Method; and
(6)	any reduction effected under paragraph (a) should be compatible with other incentives provided under the Rules.
(d)	The AER must, in accordance with the distribution consultation procedures, make and publish guidelines (the Shared Asset Guidelines) that set out the approach the AER proposes to take in applying the shared asset principles (which may include a methodology that the AER proposes to use to determine reductions for the purposes of paragraph (a)).
(e)	There must be Shared Asset Guidelines in force at all times after the date on which the AER first publishes the Shared Asset Guidelines under these Rules.
6.4.5	Expenditure Forecast Assessment Guidelines
(a)	The AER must, in accordance with the distribution consultation procedures, develop and publish guidelines (the Expenditure Forecast Assessment Guidelines) that specify the approach the AER proposes to use to assess the forecasts of operating expenditure and capital expenditure that form part of Distribution Network Service Providers' regulatory proposals and the information the AER requires for the purposes of that assessment.
(b)	There must be Expenditure Forecast Assessment Guidelines in force at all times after the date on which the AER first publishes the Expenditure Forecast Assessment Guidelines under these Rules.
6.4A	Capital expenditure incentive mechanisms
(a)	The capital expenditure incentive objective is to ensure that, where the value of a regulatory asset base is subject to adjustment in accordance with the Rules, then the only capital expenditure that is included in an adjustment that increases the value of that regulatory asset base is capital expenditure that reasonably reflects the capital expenditure criteria.
(b)	The AER must, in accordance with the distribution consultation procedures, make and publish guidelines (the Capital Expenditure Incentive Guidelines) that set out:
(1)	any capital expenditure sharing schemes developed by the AER in accordance with clause 6.5.8A, and how the AER has taken into account the capital expenditure sharing scheme principles in developing those schemes;
(2)	the manner in which it proposes to make determinations under clause S6.2.2A(a) if the overspending requirement is satisfied;
(3)	the manner in which it proposes to determine whether depreciation for establishing a regulatory asset base as at the commencement of a regulatory control period is to be based on actual or forecast capital expenditure;
(4)	the manner in which it proposes to make determinations under clause S6.2.2A(i) if the margin requirement is satisfied; and
(5)	the manner in which it proposes to make determinations under clause S6.2.2A(j) if the capitalisation requirement is satisfied; and
(6)	how each scheme and proposal referred to in subparagraphs (1) to (5), and all of them taken together, are consistent with the capital expenditure incentive objective.
(c)	There must be Capital Expenditure Incentive Guidelines in force at all times after the date on which the AER first publishes the Capital Expenditure Incentive Guidelines under these Rules.
6.5	Matters relevant to the making of building block determinations
6.5.1	Regulatory asset base
Nature of regulatory asset base
(a)	The regulatory asset base for a distribution system owned, controlled or operated by a Distribution Network Service Provider is the value of those assets that are used by the Distribution Network Service Provider to provide standard control services, but only to the extent that they are used to provide such services.
Preparation, publication and amendment of model for rolling forward regulatory asset base
(b)	The AER must, in accordance with the distribution consultation procedures, develop and publish a model for the roll forward of the regulatory asset base for distribution systems, referred to as the roll forward model.
(c)	The AER may, from time to time and in accordance with the distribution consultation procedures, amend or replace the roll forward model.
(d)	The AER must develop and publish the first roll forward model within 6 months after the commencement of this clause, and there must be such a model available at all times after that date.
Contents of roll forward model
(e)	The roll forward model must set out the method for determining the roll forward of the regulatory asset base for distribution systems:
(1)	from the immediately preceding regulatory control period to the beginning of the first year of the subsequent regulatory control period, so as to establish the value of the regulatory asset base as at the beginning of the first regulatory year of that subsequent regulatory control period; and
(2)	from one regulatory year in a regulatory control period to a subsequent regulatory year in that same regulatory control period, so as to establish the value of the regulatory asset base as at the beginning of that subsequent regulatory year;
under which:
(3)	the roll forward of the regulatory asset base from the immediately preceding regulatory control period to the beginning of the first regulatory year of a subsequent regulatory control period entails the value of the first mentioned regulatory asset base being adjusted for actual inflation, consistently with the method used for the indexation of the control mechanism (or control mechanisms) for standard control services during the preceding regulatory control period.
Other provisions relating to regulatory asset base
(f)	Other provisions relating to regulatory asset bases are set out in schedule 6.2.
6.5.2	Return on capital
Calculation of return on capital
(a)	The return on capital for each regulatory year must be calculated by applying a rate of return for the relevant Distribution Network Service Provider for that regulatory year that is determined in accordance with this clause 6.5.2 (the allowed rate of return) to the value of the regulatory asset base for the relevant distribution system as at the beginning of that regulatory year (as established in accordance with clause 6.5.1 and schedule 6.2).
Allowed rate of return
(b)	The allowed rate of return is to be determined such that it achieves the allowed rate of return objective.
(c)	The allowed rate of return objective is that the rate of return for a Distribution Network Service Provider is to be commensurate with the efficient financing costs of a benchmark efficient entity with a similar degree of risk as that which applies to the Distribution Network Service Provider in respect of the provision of standard control services (the allowed rate of return objective).
(d)	Subject to paragraph (b), the allowed rate of return for a regulatory year must be:
(1)	a weighted average of the return on equity for the regulatory control period in which that regulatory year occurs (as estimated under paragraph (f)) and the return on debt for that regulatory year (as estimated under paragraph (h)); and
(2)	determined on a nominal vanilla basis that is consistent with the estimate of the value of imputation credits referred to in clause 6.5.3.
(e)	In determining the allowed rate of return, regard must be had to:
(1)	relevant estimation methods, financial models, market data and other evidence;
(2)	the desirability of using an approach that leads to the consistent application of any estimates of financial parameters that are relevant to the estimates of, and that are common to, the return on equity and the return on debt; and
(3)	any interrelationships between estimates of financial parameters that are relevant to the estimates of the return on equity and the return on debt.
Return on equity
(f)	The return on equity for a regulatory control period must be estimated such that it contributes to the achievement of the allowed rate of return objective. 
(g)	In estimating the return on equity under paragraph (f), regard must be had to the prevailing conditions in the market for equity funds.
Return on debt
(h)	The return on debt for a regulatory year must be estimated such that it contributes to the achievement of the allowed rate of return objective.
(i)	The return on debt may be estimated using a methodology which results in either:
(1)	the return on debt for each regulatory year in the regulatory control period being the same; or
(2)	the return on debt (and consequently the allowed rate of return) being, or potentially being, different for different regulatory years in the regulatory control period.
(j)	Subject to paragraph (h), the methodology adopted to estimate the return on debt may, without limitation, be designed to result in the return on debt reflecting:
(1)	the return that would be required by debt investors in a benchmark efficient entity if it raised debt at the time or shortly before the making of the distribution determination for the regulatory control period;
(2)	the average return that would have been required by debt investors in a benchmark efficient entity if it raised debt over an historical period prior to the commencement of a regulatory year in the regulatory control period; or
(3)	some combination of the returns referred to in subparagraphs (1) and (2).
(k)	In estimating the return on debt under paragraph (h), regard must be had to the following factors:
(1)	the desirability of minimising any difference between the return on debt and the return on debt of a benchmark efficient entity referred to in the allowed rate of return objective;
(2)	the interrelationship between the return on equity and the return on debt;
(3)	the incentives that the return on debt may provide in relation to capital expenditure over the regulatory control period, including as to the timing of any capital expenditure; and 
(4)	any impacts (including in relation to the costs of servicing debt across regulatory control periods) on a benchmark efficient entity referred to in the allowed rate of return objective that could arise as a result of changing the methodology that is used to estimate the return on debt from one regulatory control period to the next.
(l)	If the return on debt is to be estimated using a methodology of the type referred to in paragraph (i)(2) then a resulting change to the Distribution Network Service Provider's annual revenue requirement must be effected through the automatic application of a formula that is specified in the distribution determination.
Rate of Return Guidelines
(m)	The AER must, in accordance with the distribution consultation procedures, make and publish guidelines (the Rate of Return Guidelines).
(n)	The Rate of Return Guidelines must set out:
(1)	the methodologies that the AER proposes to use in estimating the allowed rate of return, including how those methodologies are proposed to result in the determination of a return on equity and a return on debt in a way that is consistent the allowed rate of return objective; and
(2)	the estimation methods, financial models, market data and other evidence the AER proposes to take into account in estimating the return on equity, the return on debt and the value of imputation credits referred to in clause 6.5.3. 
(o)	There must be Rate of Return Guidelines in force at all times after the date on which the AER first publishes the Rate of Return Guidelines under these Rules.
(p)	The AER must, in accordance with the distribution consultation procedures, review the Rate of Return Guidelines:
(1)	at intervals not exceeding five years for the first interval and three years for all subsequent intervals, with the first interval starting from the date that the first Rate of Return Guidelines are published under these Rules; and 
(2)	at the same time as it reviews the Rate of Return Guidelines made under clause 6A.6.2.
(q)	For the avoidance of doubt, nothing prevents the AER from publishing the Rate of Return Guidelines made under this clause 6.5.2 in the same document as the Rate of Return Guidelines made under clause 6A.6.2.
6.5.3	Estimated cost of corporate income tax
The estimated cost of corporate income tax of a Distribution Network Service Provider for each regulatory year (ETCt) must be estimated in accordance with the following formula:
ETCt = (ETIt × rt) (1 – γ)
where:
ETIt is an estimate of the taxable income for that regulatory year that would be earned by a benchmark efficient entity as a result of the provision of standard control services if such an entity, rather than the Distribution Network Service Provider, operated the business of the Distribution Network Service Provider, such estimate being determined in accordance with the post-tax revenue model;
rt is the expected statutory income tax rate for that regulatory year as determined by the AER; and
γ is the value of imputation credits.
6.5.4	[Deleted]
6.5.5	Depreciation
(a)	The depreciation for each regulatory year:
(1)	must be calculated on the value of the assets as included in the regulatory asset base, as at the beginning of that regulatory year, for the relevant distribution system; and
(2)	must be calculated:
(i)	providing such depreciation schedules conform with the requirements set out in paragraph (b), using the depreciation schedules for each asset or category of assets that are nominated in the relevant Distribution Network Service Provider's building block proposal; or
(ii)	to the extent the depreciation schedules nominated in the Distribution Network Service Provider's building block proposal do not so conform, using the depreciation schedules determined for that purpose by the AER.
(b)	The depreciation schedules referred to in paragraph (a) must conform to the following requirements:
(1)	the schedules must depreciate using a profile that reflects the nature of the assets or category of assets over the economic life of that asset or category of assets;
(2)	the sum of the real value of the depreciation that is attributable to any asset or category of assets over the economic life of that asset or category of assets (such real value being calculated as at the time the value of that asset or category of assets was first included in the regulatory asset base for the relevant distribution system) must be equivalent to the value at which that asset or category of assets was first included in the regulatory asset base for the relevant distribution system;
(3)	the economic life of the relevant assets and the depreciation methods and rates underpinning the calculation of depreciation for a given regulatory control period must be consistent with those determined for the same assets on a prospective basis in the distribution determination for that period.
6.5.6	Forecast operating expenditure
(a)	A building block proposal must include the total forecast operating expenditure for the relevant regulatory control period which the Distribution Network Service Provider considers is required in order to achieve each of the following (the operating expenditure objectives):
(1)	meet or manage the expected demand for standard control services over that period;
(2)	comply with all applicable regulatory obligations or requirements associated with the provision of standard control services;
(3)	to the extent that there is no applicable regulatory obligation or requirement in relation to:
(i)	the quality, reliability or security of supply of standard control services; or
(ii)	the reliability or security of the distribution system through the supply of standard control services,
to the relevant extent:
(iii)	maintain the quality, reliability and security of supply of standard control services; and

Forecast capital expenditure and contingent projects
(f)	Paragraphs (g) - (j) apply where:
(1)	in a regulatory control period (the first regulatory control period), the AER determines under clause 6.6A.2(e)(1)(iii) that the likely completion date for a contingent project is a date which occurs in the immediately following regulatory control period (the second regulatory control period); and
(2)	there is an unspent amount of capital expenditure for that contingent project under paragraph (g).
(g)	A Distribution Network Service Provider's regulatory proposal for the second regulatory control period must include in the forecast of required capital expenditure referred to in paragraph (a) an amount of any unspent capital expenditure for each contingent project as described in subparagraph (f)(2), that equals the difference (if any) between:
(1)	the total capital expenditure for that contingent project, as determined by the AER in the first regulatory control period under clause 6.6A.2(e)(1)(ii); and
(2)	the total of the capital expenditure actually incurred (or estimated capital expenditure for any part of the first regulatory control period for which actual capital expenditure is not available) in the first regulatory control period for that contingent project.
(h)	The AER must include in any forecast capital expenditure for the second regulatory control period which is accepted in accordance with paragraph (c) or substituted in accordance with clause 6.12.1(3)(ii) (as the case may be) the amount of any unspent capital expenditure calculated in accordance with paragraph (g).
(i)	Without limiting the requirement in paragraph (h), in deciding whether or not to accept the forecast of required capital expenditure of a Distribution Network Service Provider for the second regulatory control period in accordance with this clause 6.5.7, the AER must not:
(1)	assess the reasonableness of the amount of unspent capital expenditure for a contingent project referred to in paragraph (g) or the remaining period to which the contingent project applies;
(2)	assess the reasonableness of the timing of the unspent capital expenditure within the remaining period for a contingent project referred to in paragraph (g) except as part of the assessment of the total forecast capital expenditure under paragraph (c); or
(3)	take into account any amount which represents for a contingent project referred to in paragraph (g) the difference between:
(i)	the amount representing the sum of the forecast capital expenditure for that contingent project for each year of the immediately preceding regulatory control period referred to in clause 6.6A.2(e)(1)(i); and
(ii)	the total capital expenditure actually incurred (or estimated capital expenditure for any part of the preceding regulatory control period for which actual capital expenditure is not available) in the immediately preceding regulatory control period for that contingent project.
(j)	A regulatory proposal in respect of the second regulatory control period must not include in the forecast of required capital expenditure referred to in paragraph (a) any capital expenditure for a contingent project for the first regulatory control period:
(1)	to the extent that the capital expenditure was included in the amount of capital expenditure for that contingent project as determined in the first regulatory control period under clause 6.6A.2(e)(1)(i); and
(2)	the capital expenditure actually incurred (or estimated capital expenditure for any part of the first regulatory control period for which actual capital expenditure is not available) in the first regulatory control period for that contingent project exceeded the capital expenditure referred to in subparagraph (1).
6.5.8	Efficiency benefit sharing scheme
(a)	The AER must, in accordance with the distribution consultation procedures, develop and publish an incentive scheme or schemes (efficiency benefit sharing scheme) that provide for a fair sharing between Distribution Network Service Providers and Distribution Network Users of:
(1)	the efficiency gains derived from the operating expenditure of Distribution Network Service Providers for a regulatory control period being less than; and
(2)	the efficiency losses derived from the operating expenditure of Distribution Network Service Providers for a regulatory control period being more than,
the forecast operating expenditure accepted or substituted by the AER for that regulatory control period.
(b)	An efficiency benefit sharing scheme may (but is not required to) be developed to cover efficiency gains and losses related to distribution losses.
(c)	In developing and implementing an efficiency benefit sharing scheme, the AER must have regard to:
(1)	the need to ensure that benefits to electricity consumers likely to result from the scheme are sufficient to warrant any reward or penalty under the scheme for Distribution Network Service Providers;
(2)	the need to provide Distribution Network Service Providers with a continuous incentive, so far as is consistent with economic efficiency, to reduce operating expenditure ;
(3)	the desirability of both rewarding Distribution Network Service Providers for efficiency gains and penalising Distribution Network Service Providers for efficiency losses;
(4)	any incentives that Distribution Network Service Providers may have to capitalise expenditure; and
(5)	the possible effects of the scheme on incentives for the implementation of non-network options.
(d)	The AER may, from time to time and in accordance with the distribution consultation procedures, amend or replace an efficiency benefit sharing scheme.
6.5.8A	Capital expenditure sharing scheme
(a)	A capital expenditure sharing scheme is a scheme that provides Distribution Network Service Providers with an incentive to undertake efficient capital expenditure during a regulatory control period.
(b)	If the AER develops a capital expenditure sharing scheme in accordance with this clause, the capital expenditure sharing scheme must be consistent with the capital expenditure incentive objective.
(c)	In developing a capital expenditure sharing scheme, the AER must take into account the following principles (the capital expenditure sharing scheme principles):
(1)	Distribution Network Service Providers should be rewarded or penalised for improvements or declines in efficiency of capital expenditure; and
(2)	the rewards and penalties should be commensurate with the efficiencies or inefficiencies in capital expenditure, but a reward for efficient capital expenditure need not correspond in amount to a penalty for the same amount of inefficient capital expenditure.
(d)	In developing a capital expenditure sharing scheme, the AER must also take into account:
(1)	the interaction of the scheme with other incentives that Distribution Network Service Providers may have in relation to undertaking efficient operating or capital expenditure; and
(2)	the capital expenditure objectives and, if relevant, the operating expenditure objectives.
(e)	In deciding:
(1)	whether to apply a capital expenditure sharing scheme to a Distribution Network Service Provider for a regulatory control period; and
(2)	the nature and details of any capital expenditure sharing scheme that is to apply to a Distribution Network Service Provider for a regulatory control period,
the AER must:
(3)	make that decision in a manner that contributes to the achievement of the capital expenditure incentive objective; and
(4)	take into account:
(i)	both the capital expenditure sharing scheme principles, and the matters referred to in paragraph (d), as they apply to the Distribution Network Service Provider; and
(ii)	the circumstances of the Distribution Network Service Provider.
6.5.9	The X factor
(a)	A building block determination is to include the X factor for each control mechanism for each regulatory year of the regulatory control period.
(b)	The X factor:
(1)	must be set by the AER with regard to the Distribution Network Service Provider's total revenue requirement for the regulatory control period; and
(2)	must be such as to minimise, as far as reasonably possible, variance between expected revenue for the last regulatory year of the regulatory control period and the annual revenue requirement for that last regulatory year; and
(3)	must conform with whichever of the following requirements is applicable:
(i)	if the control mechanism relates generally to standard control services – the X factor must be designed to equalise (in terms of net present value) the revenue to be earned by the Distribution Network Service Provider from the provision of standard control services over the regulatory control period with the provider's total revenue requirement for the regulatory control period;
(ii)	if there are separate control mechanisms for different standard control services – the X factor for each control mechanism must be designed to equalise (in terms of net present value) the revenue to be earned by the Distribution Network Service Provider from the provision of standard control services to which the control mechanism relates over the regulatory control period with the portion of the provider's total revenue requirement for the regulatory control period attributable to those services.
(c)	There may be different X factors:
(1)	for different regulatory years of the regulatory control period; and
(2)	if there are 2 or more control mechanisms – for each control mechanism.
6.5.10	Pass through events
(a)	A building block proposal may include a proposal as to the events that should be defined as pass through events under clause 6.6.1(a1)(5) having regard to the nominated pass through event considerations.
(b)	In determining whether to accept the pass through events nominated by a Distribution Network Service Provider in its building block proposal under paragraph  (a), the AER must take into account the nominated pass through event considerations.
6.6	Adjustments after making of building block determination.
6.6.1	Cost pass through
(a1)	Any of the following is a pass through event for a distribution determination:
(1)	a regulatory change event;
(2)	a service standard event;
(3)	a tax change event;
(4)	a retailer insolvency event; and 
(5)	any other event specified in a distribution determination as a pass through event for the determination.
(a)	If a positive change event occurs, a Distribution Network Service Provider may seek the approval of the AER to pass through to Distribution Network Users a positive pass through amount.
(b)	If a negative change event occurs, the AER may require the Distribution Network Service Provider to pass through to Distribution Network Users a negative pass through amount as determined by the AER under paragraph (g).
Positive pass through
(c)	To seek the approval of the AER to pass through a positive pass through amount, a Distribution Network Service Provider must submit to the AER, within 90 business days of the relevant positive change event occurring, a written statement which specifies:
(1)	the details of the positive change event;
(2)	the date on which the positive change event occurred;
(3)	the eligible pass through amount in respect of that positive change event;
(4)	the positive pass through amount the Distribution Network Service Provider proposes in relation to the positive change event;
(5)	the amount of the positive pass through amount that the Distribution Network Service Provider proposes should be passed through to Distribution Network Users in the regulatory year in which, and each regulatory year after that in which, the positive change event occurred;
(6)	evidence:
(i)	of the actual and likely increase in costs referred to in subparagraph (3);
(ii)	that such costs occur solely as a consequence of the positive change event; and
(iii)	in relation to a retailer insolvency event, of :
(A)	the amount to which the Distribution Network Service Provider is entitled under any relevant credit support;
(B)	the maximum amount of credit support (if any) that the Distribution Network Service Provider was entitled to request the retailer to provide under the credit support rules; and
(C)	any amount that the Distribution Network Service Provider is likely to receive on a winding-up of the retailer; and
(7)	such other information as may be required under any relevant regulatory information instrument.
(d)	If the AER determines that a positive change event has occurred in respect of a statement under paragraph (c), the AER must determine:
(1)	the approved pass through amount; and
(2)	the amount of that approved pass through amount that should be passed through to Distribution Network Users in the regulatory year in which, and each regulatory year after that in which, the positive change event occurred,
taking into account the matters referred to in paragraph (j).
(e)	Subject to paragraph (k1), if the AER does not make the determinations referred to in paragraph (d) within 40 business days from the later of the date it receives the Distribution Network Service Provider's statement and accompanying evidence under paragraph (c), and the date it receives any additional information required under paragraph (e1), then, on the expiry of that period, the AER is taken to have determined that:
(1)	the positive pass through amount as proposed in the Distribution Network Service Provider's statement under paragraph (c) is the approved pass through amount in respect of that positive change event; and
(2)	the amount of that positive pass through amount that the Distribution Network Service Provider proposes in its statement under paragraph(c) should be passed through to Distribution Network Users in the regulatory year in which, and each regulatory year after that in which, the positive change event occurred, is the amount that should be so passed through in each such regulatory year.
(e1)	A Distribution Network Service Provider must provide the AER with such additional information as the AER requires for the purpose of making a determination under paragraph (d) within the time specified by the AER in a notice provided to the Distribution Network Service Provider by the AER for that purpose.
Negative pass through
(f)	A Distribution Network Service Provider must submit to the AER, within 90 business days of becoming aware of the occurrence of a negative change event for the Distribution Network Service Provider, a written statement which specifies:
(1)	the details of the negative change event concerned;
(2)	the date the negative change event occurred;
(3)	the costs in the provision of direct control services that the Distribution Network Service Provider has saved and is likely to save as a result of the negative change event until:
(i)	unless subparagraph (ii) applies – the end of the regulatory control period in which the negative change event occurred; or 
(ii)	if the distribution determination for the regulatory control period following that in which the negative change event occurred does not make any allowance for the pass through of those cost savings - the end of the regulatory control period following that in which the negative change event occurred; 
(4)	the aggregate amount of those saved costs that the Distribution Network Service Provider proposes should be passed through to Distribution Network Users;
(5)	the amount of the costs referred to in subparagraph (4) the Distribution Network Service Provider proposes should be passed through to Distribution Network Users in the regulatory year in which, and each regulatory year after that in which, the negative change event occurred; and
(6)	such other information as may be required under any relevant regulatory information instrument.
(f1)	If the occurrence of the negative change event is not notified by the Distribution Network Service Provider to the AER under paragraph (f) then, as soon as is reasonably practicable and before making a determination referred to in paragraph (g), the AER must notify the Distribution Network Service Provider of the occurrence of that negative change event.
(g)	If a negative change event occurs (whether or not the occurrence of that negative change event is notified by the Distribution Network Service Provider to the AER under paragraph (f)) and the AER determines to impose a requirement on the provider in relation to that negative change event as described in paragraph (b), the AER must determine:
(1)	the required pass through amount; and
(2)	taking into account the matters referred to in paragraph (j):
(i)	how much of that required pass through amount should be passed through to Distribution Network Users (the "negative pass through amount"); and
(ii)	the amount of that negative pass through amount that should be passed through to Distribution Network Users in the regulatory year in which, and each regulatory year after that in which, the negative change event occurred.
(g1)	Subject to paragraph (k1), if the AER does not make the determinations referred to in paragraph (g) within 40 business days from:
(1)	where the Distribution Network Service Provider notifies the AER of the occurrence of the negative change event under paragraph (f) - the later of the date the AER receives the Distribution Network Service Provider's statement under paragraph (f) and the date the AER receives any information required by the AER under paragraph (h); or
(2)	where the Distribution Network Service Provider does not notify the AER of the occurrence of the negative change event under paragraph (f) – the later of the date the AER notifies the Distribution Network Service Provider under paragraph (g1) and the date the AER receives any information required by the AER under paragraph (h),
then the AER is taken to have determined that the required pass through amount is zero.
(h)	A Distribution Network Service Provider must provide the AER with such information as the AER requires for the purpose of making a determination under paragraph (g) within the time specified by the AER in a notice provided to the Distribution Network Service Provider by the AER for that purpose.
Consultation
(i)	Before making a determination under paragraph (d) or (g), the AER may consult with the relevant Distribution Network Service Provider and such other persons as the AER considers appropriate, on any matters arising out of the relevant pass through event the AER considers appropriate.
Relevant factors
(j)	In making a determination under paragraph (d) or (g) in respect of a Distribution Network Service Provider, the AER must take into account:
(1)	the matters and proposals set out in any statement given to the AER by the Distribution Network Service Provider under paragraph (c) or (f); and
(2)	in the case of a positive change event, the increase in costs in the provision of direct control services that, as a result of the positive change event, the Distribution Network Service Provider has incurred and is likely to incur until:
(i)	unless subparagraph(ii) applies – the end of the regulatory control period in which the positive change event occurred; or
(ii)	if the distribution determination for the regulatory control period following that in which the positive change event occurred does not make any allowance for the recovery of that increase in costs – the end of the regulatory control period following that in which the positive change event occurred;
(2A)	in the case of a negative change event, the costs in the provision of direct control services that, as a result of the negative change event, the Distribution Network Service Provider has saved and is likely to save until:
(i)	unless subparagraph(ii) applies – the end of the regulatory control period in which the negative change event occurred; or
(ii)	if the distribution determination for the regulatory control period following that in which the negative change event occurred does not make any allowance for the pass through of those cost savings to Distribution Network Users – the end of the regulatory control period following that in which the negative change event occurred;
(3)	in the case of a positive change event, the efficiency of the Distribution Network Service Provider's decisions and actions in relation to the risk of the positive change event, including whether the Distribution Network Service Provider has failed to take any action that could reasonably be taken to reduce the magnitude of the eligible pass through amount in respect of that positive change event and whether the Distribution Network Service Provider has taken or omitted to take any action where such action or omission has increased the magnitude of the amount in respect of that positive change event;
(4)	the time cost of money based on the allowed rate of return for the Distribution Network Service Provider for the regulatory control period in which the pass through event occurred;
(5)	the need to ensure that the Distribution Network Service Provider only recovers any actual or likely increment in costs under this paragraph (j) to the extent that such increment is solely as a consequence of a pass through event;
(6)	in the case of a tax change event, any change in the way another tax is calculated, or the removal or imposition of another tax, which, in the AER's opinion, is complementary to the tax change event concerned;
(7)	whether the costs of the pass through event have already been factored into the calculation of the Distribution Network Service Provider's annual revenue requirement for the regulatory control period in which the pass through event occurred or will be factored into the calculation of the Distribution Network Service Provider's annual revenue requirement for a subsequent regulatory control period;
(7A)	the extent to which the costs that the Distribution Network Service Provider has incurred and is likely to incur are the subject of a previous determination made by the AER under this clause 6.6.1; and
(8)	any other factors that the AER considers relevant.
Extension of time limits
(k)	The AER must, by written notice to a Distribution Network Service Provider, extend a time limit fixed in paragraph (c) or (f) if the AER is satisfied that the difficulty of assessing or quantifying the effect of the relevant pass through event justifies the extension.
(k1)	If the AER is satisfied that the making of a determination under paragraph (d) or (g) involves issues of such complexity or difficulty that the time limit fixed in paragraph (e) or (g1) should be extended, the AER may extend that time limit by a further period of up to 60 business days, provided that it gives written notice to the Distribution Network Service Provider of that extension not later than 10 business days before the expiry of that time limit.
(k2)	If the AER extends a time limit under paragraph (k1), it must make available on its website a notice of that extension as soon as is reasonably practicable.
(k3)	Subject to paragraph (k6), if the AER gives a written notice to the Distribution Network Service Provider stating that it requires information from an Authority in order to make a determination under paragraph (d) or (g) then, for the purpose of calculating elapsed time, the period between when the AER gives that notice to the Distribution Network Service Provider and when the AER receives that information from that Authority is to be disregarded.
(k4)	Subject to paragraph (k6), if the AER gives a written notice to the Distribution Network Service Provider stating that, in order to make a determination under paragraph (d) or (g), it requires information that it anticipates will be made publicly available by a judicial body or royal commission then, for the purpose of calculating elapsed time, the period between when the AER gives that notice to the Distribution Network Service Provider and when that information is made publicly available is to be disregarded.
(k5)	Where the AER gives a notice to the Distribution Network Service Provider under paragraph (k3) or (k4), it must:
(1)	as soon as is reasonably practicable make available on its website a notice stating when the period referred to in paragraph (k3) or (k4), as the case may be, has commenced; 
(2)	as soon as is reasonably practicable make available on its website a notice stating when the period referred to in paragraph (k3) or (k4), as the case may be, has ended; and 
(3)	if the information specified in that notice is required from an Authority, promptly request that information from the relevant Authority.
(k6)	Paragraphs (k3) and (k4) do not apply if the AER gives the notice specified in those paragraphs to the Distribution Network Service Provider later than 10 business days before the expiry of the time limit fixed in paragraphs (e) or (g1).
retailer insolvency event
(l)	For the purposes of calculating the eligible pass through amount in relation to a positive change event which is a retailer insolvency event, the increase in costs is the retailer insolvency costs excluding:
(i)	any amount recovered or recoverable from a retailer or a guarantor of a retailer under any relevant credit support; and
(ii)	amounts that the Distribution Network Service Provider is likely to receive on a winding-up of the retailer; and
(iii)	any costs that are recoverable under a RoLR cost recovery scheme distributor payment determination .
(m)	The amount the AER determines should be passed through to Distribution Network Users in respect of a retailer insolvency event must be taken to be a cost that can be passed through and not a revenue impact of the event.
6.6.1A	Reporting on jurisdictional schemes
(a)	If during a regulatory control period:
(1)	a scheme becomes a jurisdictional scheme; or
(2)	a Distribution Network Service Provider first becomes subject to jurisdictional scheme obligations under a jurisdictional scheme; and
(3)	the relevant jurisdictional scheme is not an approved jurisdictional scheme,
then a Distribution Network Service Provider may request the AER to determine how the Distribution Network Service Provider is to report to the AER on its recovery of jurisdictional scheme amounts in respect of that scheme for each regulatory year of the regulatory control period and on the adjustments to be made to subsequent pricing proposals to account for over or under recovery of those amounts.
(b)	To make a request under paragraph (a), a Distribution Network Service Provider must submit to the AER, as soon as practicable after the event referred to in subparagraph (a)(1) or (2), a written statement which specifies:
(1)	the name of the relevant jurisdictional scheme;
(2)	the date of the event referred to in subparagraph (a)(1) or (2);
(3)	details of how the Distribution Network Service Provider proposes to:
(i)	estimate the jurisdictional scheme amounts for the relevant jurisdictional scheme for the purposes of clause 6.18.7A(b);
(ii)	carry out any adjustments to jurisdictional scheme amounts for the relevant jurisdictional scheme for the purposes of clause 6.18.7A(b); and
(iii)	report to the AER on the recovery process under clause 6.18.7A (a) to (c).
(c)	The AER must as soon as practicable after receiving a statement under paragraph (b), publish the statement.
(d)	Before making a determination under paragraph (e), the AER may consult with the relevant Distribution Network Service Provider and such other persons as the AER considers appropriate, on any matters arising out of the statement the AER considers appropriate.
(e)	Within 60 business days of receiving the statement under paragraph (b), the AER must make a determination on how the Distribution Network Service Provider is to report to the AER on its recovery of jurisdictional scheme amounts for the relevant jurisdictional scheme for each regulatory year of the regulatory control period and on the adjustments to be made to subsequent pricing proposals to account for over or under recovery of those amounts.
(f)	If the AER does not make the determination referred to in paragraph (e) within 60 business days of receiving the statement under paragraph (b) then, on expiry of that period, the AER is taken to have approved the process proposed in the Distribution Network Service Provider’s statement.
6.6.2	Service target performance incentive scheme
(a)	The AER must, in accordance with the distribution consultation procedures, develop and publish an incentive scheme or schemes (service target performance incentive scheme) to provide incentives (which may include targets) for Distribution Network Service Providers to maintain and improve performance.
(b)	In developing and implementing a service target performance incentive scheme, the AER:
(1)	must consult with the authorities responsible for the administration of relevant jurisdictional electricity legislation; and
(2)	must ensure that service standards and service targets (including guaranteed service levels) set by the scheme do not put at risk the Distribution Network Service Provider's ability to comply with relevant service standards and service targets (including guaranteed service levels) as specified in jurisdictional electricity legislation; and
Note:
A service target performance incentive scheme operates concurrently with any average or minimum service standards and guaranteed service level schemes that apply to the Distribution Network Service Provider under jurisdictional electricity legislation.
(3)	must take into account:
(i)	the need to ensure that benefits to electricity consumers likely to result from the scheme are sufficient to warrant any reward or penalty under the scheme for Distribution Network Service Providers; and
(ii)	any regulatory obligation or requirement to which the Distribution Network Service Provider is subject; and
(iii)	the past performance of the distribution network; and
(iv)	any other incentives available to the Distribution Network Service Provider under the Rules or a relevant distribution determination; and
(v)	the need to ensure that the incentives are sufficient to offset any financial incentives the Distribution Network Service Provider may have to reduce costs at the expense of service levels; and
(vi)	the willingness of the customer or end user to pay for improved performance in the delivery of services; and
(vii)	the possible effects of the scheme on incentives for the implementation of non-network options .
(c)	The AER may, from time to time and in accordance with the distribution consultation procedures, amend or replace any scheme that is developed and published under this clause.
Note:
A Distribution Network Service Provider is not precluded from entering into a contract with a third party (such as a network support service provider) under which the benefits of a service target performance incentive scheme are passed on to the third party, or the third party is required to indemnify the provider for penalties to which the provider becomes liable under the scheme.
6.6.3	Demand management incentive scheme
(a)	The AER must develop a demand management incentive scheme consistent with the demand management incentive scheme objective.
(b)	The objective of the demand management incentive scheme is to provide Distribution Network Service Providers with an incentive to undertake efficient expenditure on relevant non-network options relating to demand management (the demand management incentive scheme objective).
(c)	In developing, and applying, any demand management incentive scheme, the AER must take into account the following:
(1)	the scheme should be applied in a manner that contributes to the achievement of the demand management incentive scheme objective;
(2)	the scheme should reward Distribution Network Service Providers for implementing relevant non-network options that deliver net cost savings to retail customers;
(3)	the scheme should balance the incentives between expenditure on network options and non-network options relating to demand management. In doing so, the AER may take into account the net economic benefits delivered to all those who produce, consume and transport electricity in the market associated with implementing relevant non-network options;
(4)	the level of the incentive:
(i)	should be reasonable, considering the long term benefit to retail customers;
(ii)	should not include costs that are otherwise recoverable from any another source, including under a relevant distribution determination; and 
(iii)	may vary by Distribution Network Service Provider and over time;
(5)	penalties should not be imposed on Distribution Network Service Providers under any scheme;
(6)	the incentives should not be limited by the length of a regulatory control period, if such limitations would not contribute to the achievement of the demand management incentive scheme objective; and
(7)	the possible interaction between the scheme and:
(i)	any other incentives available to the Distribution Network Service Provider in relation to undertaking efficient expenditure on, or implementation of, relevant non-network options;
(ii)	particular control mechanisms and their effect on a Distribution Network Service Provider's available incentives referred to in sub-paragraph (i); and
(iii)	meeting any regulatory obligation or requirement.
(d)	The AER:
(1)	must develop and publish the scheme; and
(2)	may, from time to time, amend or replace the scheme developed and published under this clause,
in accordance with the distribution consultation procedures.
6.6.3A	Demand management innovation allowance mechanism
(a)	The AER must develop a demand management innovation allowance mechanism consistent with the demand management innovation allowance objective.
(b)	The objective of the demand management innovation allowance mechanism is to provide Distribution Network Service Providers with funding for research and development in demand management projects that have the potential to reduce long term network costs (the demand management innovation allowance objective).
(c)	In developing and applying any demand management innovation allowance mechanism, the AER must take into account the following:
(1)	the mechanism should be applied in a manner that contributes to the achievement of the demand management innovation allowance objective;
(2)	demand management projects, the subject of the allowance, should:
(i)	have the potential to deliver ongoing reductions in demand or peak demand; and
(ii)	be innovative and not be otherwise efficient and prudent non-network options that a Distribution Network Service Providers should have provided for in its regulatory proposal;
(3)	the level of the allowance:
(i)	should be reasonable, considering the long term benefit to retail customers;
(ii)	should only provide funding that is not available from any another source, including under a relevant distribution determination; and
(iii)	may vary by Distribution Network Service Provider and over time;
(4)	the allowance may fund demand management projects which occur over a period longer than a regulatory control period.
(d)	Any mechanism developed and applied by the AER must require Distribution Network Service Providers to publish reports on the nature and results of demand management projects the subject of the allowance.
(e)	The AER:
(1)	must develop and publish the mechanism; and
(2)	may, from time to time, amend or replace any mechanism developed and published under this clause,
in accordance with the distribution consultation procedures.
6.6.4	Small-scale incentive scheme
(a)	The AER may, in accordance with the distribution consultation procedures, develop and publish an incentive scheme or schemes (small-scale incentive scheme) that provides Distribution Network Service Providers with incentives to provide standard control services in a manner that contributes to the achievement of the national electricity objective.
(b)	In developing and applying a small-scale incentive scheme, the AER must have regard to the following matters:
(1)	Distribution Network Service Providers should be rewarded or penalised for efficiency gains or losses in respect of their distribution systems;
(2)	the rewards and penalties should be commensurate with the efficiency gains or efficiency losses in respect of a distribution system, but a reward for efficiency gains need not correspond in amount to a penalty for efficiency losses;
(3)	the benefits to electricity consumers that are likely to result from efficiency gains in respect of a distribution system should warrant the rewards provided under the scheme, and the detriments to electricity consumers that are likely to result from efficiency losses in respect of a distribution system should warrant the penalties provided under the scheme;
(4)	the interaction of the scheme with other incentives that Distribution Network Service Providers may have under the Rules; and
(5)	the capital expenditure objectives and the operating expenditure objectives.
(c)	The AER may, from time to time and in accordance with the distribution consultation procedures, amend or replace any small-scale incentive scheme.
(d)	Where the AER applies a small-scale incentive scheme to a Distribution Network Service Provider for a regulatory control period:
(1)	the aggregate rewards or penalties for a regulatory year in that regulatory period that are provided or imposed under that scheme and any other small-scale incentive schemes that apply to that Distribution Network Service Provider must not exceed 0.5% of the annual revenue requirement for the Distribution Network Service Provider for that regulatory year unless the Distribution Network Service Provider consents to the contrary, in which case that aggregate must not exceed 1% of the annual revenue requirement for the Distribution Network Service Provider for that regulatory year; and
(2)	the small-scale incentive scheme must cease to provide rewards or impose penalties in respect of a regulatory year after the expiry of such a period as is determined by the AER, being a period that is not more than two regulatory control periods after the commencement of that scheme.
(e)	Notwithstanding anything else contained in this clause, the AER may require a Distribution Network Service Provider to participate in a trial of a small-scale incentive scheme under which, for the duration of that trial, the Distribution Network Service Provider is not required to bear any penalty and is not entitled to earn any reward.
6.6.5	Reopening of distribution determination for capital expenditure
(a)	Subject to paragraph (b), a Distribution Network Service Provider may, during a regulatory control period, apply to the AER to revoke and substitute a distribution determination that applies to it where:
(1)	an event that is beyond the reasonable control of the Distribution Network Service Provider has occurred during that regulatory control period and the occurrence of that event during that period (or of an event of a similar kind) could not reasonably have been foreseen by the Distribution Network Service Provider at the time of the making of the distribution determination ('the event');
(2)	no forecast capital expenditure was accepted or substituted by the AER for that period under clauses 6.5.7(c) or 6.12.1(3)(ii) (as the case may be) in relation to the event that has occurred;
(3)	the Distribution Network Service Provider proposes to undertake capital expenditure to rectify the adverse consequences of the event;
(4)	the total of the capital expenditure required during the regulatory control period to rectify the adverse consequences of the event:
(i)	exceeds 5% of the value of the regulatory asset base for the relevant Distribution Network Service Provider for the first year of the relevant regulatory control period;
(ii)	is such that, if undertaken, it is reasonably likely (in the absence of any other reduction in capital expenditure) to result in the total actual capital expenditure for that regulatory control period exceeding the total of the forecast capital expenditure for that regulatory control period as accepted or substituted by the AER in accordance with clauses 6.5.7(c) or 6.12.1(3)(ii) (as the case may be);
(5)	the Distribution Network Service Provider can demonstrate that it is not able to reduce capital expenditure in other areas to avoid the consequence referred to in subparagraph (a)(4)(ii) without materially adversely affecting the reliability and security of the relevant distribution system;
(6)	a failure to rectify the adverse consequences of the event would be likely to materially adversely affect the reliability and security of the relevant distribution system; and
(7)	the event is not a pass through event or a contingent project.
In this paragraph (a), a reference to an event includes a series of events or a state of affairs, which may include a greater than anticipated increase in demand.
(b)	An application referred to in paragraph (a) must not be made within 90 business days prior to the end of a regulatory year.
(c)	Following its receipt of an application made in accordance with paragraphs (a) and (b), the AER must:
(1)	consult with the Distribution Network Service Provider and such other persons as it considers appropriate in relation to the application; and
(2)	make its decision on the application within 40 business days from the later of the date the AER receives the application and the date the AER receives any information required by the AER under paragraph (g).
(d)	The AER must, and must only, revoke a distribution determination following an application made in accordance with paragraphs (a) and (b) if the AER is satisfied of each of the matters referred to in paragraph (a).
(e)	If the AER revokes a distribution determination under paragraph (d), the AER must make a new distribution determination in substitution for the revoked determination to apply for the remainder of the regulatory control period for which the revoked determination was to apply.
(f)	The substituted distribution determination must only vary from the revoked distribution determination to the extent necessary:
(1)	to adjust the forecast capital expenditure for that regulatory control period to accommodate the amount of such additional capital expenditure as the AER determines is appropriate (in which case the amount of that adjustment will be taken to be accepted by the AER under clause 6.5.7(c)); and
(2)	to reflect the effect of any resultant increase in forecast capital expenditure on:
(i)	the forecast operating expenditure for the remainder of the regulatory control period;
(ii)	the annual revenue requirement for each regulatory year in the remainder of the regulatory control period; and
(iii)	the X factor for each of the remaining regulatory years of the regulatory control period.
(g)	A Distribution Network Service Provider must provide the AER with such additional information as the AER requires for the purpose of making a decision on an application made by that Distribution Network Service Provider under paragraph (a) within the time specified by the AER in a notice provided to the Distribution Network Service Provider by the AER for that purpose.
Extension of time limit
(h)	If the AER is satisfied that the revocation and substitution of a distribution determination under paragraphs (d) and (e) involves issues of such complexity or difficulty that the time limit fixed in subparagraph (c)(2) should be extended, the AER may extend that time limit by a further period of up to 60 business days, provided that it gives written notice to the Distribution Network Service Provider of that extension not later than 10 business days before the expiry of that time limit.
(i)	If the AER extends the time limit under paragraph (h), it must make available on its website a notice of that extension as soon as is reasonably practicable.
(j)	Subject to paragraph (l1), if the AER gives a written notice to the Distribution Network Service Provider stating that it requires information from an Authority in order to make a decision on an application made by the Distribution Network Service Provider under paragraph (a) then, for the purpose of calculating elapsed time, the period between when the AER gives that notice to the Distribution Network Service Provider and when the AER receives that information from that Authority is to be disregarded.
(k)	Subject to paragraph (l1), if the AER gives a written notice to the Distribution Network Service Provider stating that, in order to make a decision on an application made by the Distribution Network Service Provider under paragraph (a), it requires information that it anticipates will be made publicly available by a judicial body or royal commission then, for the purpose of calculating elapsed time, the period between when the AER gives that notice to the Distribution Network Service Provider and when that information is made publicly available is to be disregarded.
(l)	Where the AER gives a notice to the Distribution Network Service Provider under paragraph (j) or (k), it must:
(1)	as soon as is reasonably practicable make available on its website a notice stating when the period referred to in paragraph (j) or (k), as the case may be, has commenced; 
(2)	as soon as is reasonably practicable make available on its website a notice stating when the period referred to in paragraph (j) or (k), as the case may be, has ended; and 
(3)	if the information specified in that notice is required from an Authority, promptly request that information from the relevant Authority.
(l1)	Paragraphs (j) and (k) do not apply if the AER gives the notice specified in those paragraphs to the Distribution Network Service Provider later than 10 business days before the expiry of the time limit fixed in subparagraph (c)(2).
Revocation and substitution of distribution determination
(m)	If the AER revokes and substitutes a distribution determination under paragraph (e), that revocation and substitution must take effect from the commencement of the next regulatory year.
6.6A	Contingent Projects
6.6A.1	Acceptance of a contingent project in a distribution determination
(a)	A regulatory proposal may include proposed contingent capital expenditure, which the Distribution Network Service Provider considers is reasonably required for the purpose of undertaking a proposed contingent project.
(b)	The AER must determine that a proposed contingent project is a contingent project if the AER is satisfied that:
(1)	the proposed contingent project is reasonably required to be undertaken in order to achieve any of the capital expenditure objectives;
(2)	the proposed contingent capital expenditure:
(i)	is not otherwise provided for (either in part or in whole) in the total of the forecast capital expenditure for the relevant regulatory control period which is accepted in accordance with clause 6.5.7(c) or substituted in accordance with clause 6.12.1(3)(ii) (as the case may be);
(ii)	reasonably reflects the capital expenditure criteria, taking into account the capital expenditure factors, in the context of the proposed contingent project as described in the regulatory proposal; and
(iii)	exceeds either $30 million or 5% of the value of the annual revenue requirement for the relevant Distribution Network Service Provider for the first year of the relevant regulatory control period, whichever is the larger amount;
(3)	the proposed contingent project and the proposed contingent capital expenditure, as described or set out in the regulatory proposal, and the information provided in relation to these matters, complies with the relevant requirements of any relevant regulatory information instrument; and
(4)	the trigger events in relation to the proposed contingent project which are proposed by the Distribution Network Service Provider in its regulatory proposal are appropriate.
(c)	In determining whether a trigger event in relation to a proposed contingent project is appropriate for the purposes of subparagraph (b)(4), the AER must have regard to the need for a trigger event:
(1)	to be reasonably specific and capable of objective verification;
(2)	to be a condition or event, which, if it occurs, makes the undertaking of the proposed contingent project reasonably necessary in order to achieve any of the capital expenditure objectives;
(3)	to be a condition or event that generates increased costs or categories of costs that relate to a specific location rather than a condition or event that affects the distribution network as a whole;
(4)	to be described in such terms that the occurrence of that event or condition is all that is required for the distribution determination to be amended under clause 6.6A.2; and
(5)	to be an event or condition, the occurrence of which is probable during the regulatory control period, but the inclusion of capital expenditure in relation to it under clause 6.5.7 is not appropriate because:
(i)	it is not sufficiently certain that the event or condition will occur during the regulatory control period or if it may occur after that regulatory control period or not at all; or
(ii)	subject to the requirement to satisfy subparagraph (b)(2)(iii), the costs associated with the event or condition are not sufficiently certain.
6.6A.2	Amendment of distribution determination for contingent project
(a)	Subject to paragraph (b), a Distribution Network Service Provider may, during a regulatory control period, apply to the AER to amend a distribution determination that applies to that Distribution Network Service Provider where a trigger event for a contingent project in relation to that distribution determination has occurred.
(b)	An application referred to in paragraph (a):
(1)	must not be made within 90 business days prior to the end of a regulatory year;

(iii)	a forecast of the capital and incremental operating expenditure, for each remaining regulatory year which the Distribution Network Service Provider considers is reasonably required for the purpose of undertaking the contingent project;
(iv)	how the forecast of the total capital expenditure for the contingent project meets the threshold as referred to in clause 6.6A.1(b)(2)(iii);
(v)	the intended date for commencing the contingent project (which must be during the regulatory control period);
(vi)	the anticipated date for completing the contingent project (which may be after the end of the regulatory control period);
(vii)	an estimate of the incremental revenue which the Distribution Network Service Provider considers is likely to be required to be earned in each remaining regulatory year of the regulatory control period as a result of the contingent project being undertaken as described in subparagraph (iii); and
(4)	the estimate referred to in subparagraph (3)(vii) must be calculated:
(i)	in accordance with the requirements of the post-tax revenue model referred to in clause 6.4.1;
(ii)	in accordance with the requirements of the roll forward model referred to in clause 6.5.1(b);
(iii)	using the allowed rate of return for that Distribution Network Service Provider for the regulatory control period as determined in accordance with clause 6.5.2;

(d)	The AER must consider any written submissions made under paragraph (c) and must make its decision on the application within 40 business days from the later of the date the AER receives the application and the date the AER receives any information required by the AER under paragraph (i). In doing so the AER may also take into account such other information as it considers appropriate, including any analysis (such as benchmarking) that is undertaken by it for that purpose.
(e)	If the AER is satisfied that the trigger event has occurred, and that the forecast of the total capital expenditure for the contingent project meets the threshold as referred to in clause 6.6A.1(b)(2)(iii), it must:
(1)	determine:
(i)	the amount of capital and incremental operating expenditure, for each remaining regulatory year, which the AER considers is reasonably required for the purpose of undertaking the contingent project;
(ii)	the total capital expenditure which the AER considers is reasonably required for the purpose of undertaking the contingent project;
(iii)	the likely commencement and completion dates for the contingent project; and
(iv)	the incremental revenue which is likely to be required by the Distribution Network Service Provider in each remaining regulatory year as a result of the contingent project being undertaken as described in subparagraphs (i) and (ii), such estimate being calculated in accordance with subparagraph (2);

(ii)	otherwise in accordance with subparagraph (b)(4); and
(3)	amend the distribution determination in accordance with paragraph (h).
(f)	In making the determinations referred to in subparagraph (e)(1), the AER must accept the relevant amounts and dates, contained in the Distribution Network Service Provider’s application, as referred to in subparagraph (b)(3)(ii) to (vii), if the AER is satisfied that:
(1)	the forecast of the total capital expenditure for the contingent project meets the threshold as referred to in clause 6.6A.1(b)(2)(iii);
(2)	the amounts of forecast capital expenditure and incremental operating expenditure reasonably reflect the capital expenditure criteria and the operating expenditure criteria, taking into account the capital expenditure factors and the operating expenditure factors respectively, in the context of the contingent project;
(3)	the estimates of incremental revenue are reasonable; and
(4)	the dates are reasonable.
(g)	In making the determinations referred to in subparagraph (e)(1) and paragraph (f), the AER must have regard to:
(1)	the information included in or accompanying the application;
(2)	submissions received in the course of consulting on the application;
(3)	such analysis as is undertaken by or for the AER;
(4)	the expenditure that would be incurred in respect of a contingent project by an efficient and prudent Distribution Network Service Provider in the circumstances of the Distribution Network Service Provider;
(5)	the actual and expected capital expenditure of the Distribution Network Service Provider for contingent projects during any preceding regulatory control periods;
(6)	the extent to which the forecast capital expenditure for the contingent project is referable to arrangements with a person other than the Distribution Network Service Provider that, in the opinion of the AER, do not reflect arm’s length terms;
(7)	the relative prices of operating and capital inputs in relation to the contingent project;
(8)	the substitution possibilities between operating and capital expenditure in relation to the contingent project; and
(9)	whether the capital and operating expenditure forecasts for the contingent project are consistent with any incentive scheme or schemes that apply to the Distribution Network Service Provider under clauses 6.5.8, 6.5.8A or 6.6.2 to 6.6.4.
(h)	Amendments to a distribution determination referred to in subparagraph (e)(3) must only vary the determination to the extent necessary:
(1)	to adjust the forecast capital expenditure for that regulatory control period to accommodate the amount of capital expenditure determined under subparagraph (e)(1)(i) (in which case the amount of that adjustment will be taken to be accepted by the AER under clause 6.5.7(c));
(2)	to adjust the forecast operating expenditure for that regulatory control period to accommodate the amount of incremental operating expenditure determined under subparagraph (e)(1)(i) (in which case the amount of that adjustment will be taken to be accepted by the AER under clause 6.5.6(c));
(3)	to reflect the effect of any resultant increase in forecast capital and operating expenditure on:
(i)	the annual revenue requirement for each regulatory year in the remainder of the regulatory control period; and
(ii)	the X factor for each regulatory year in the remainder of the regulatory control period.
(i)	A Distribution Network Service Provider must provide the AER with such additional information as the AER requires for the purpose of making a decision on an application made by that Distribution Network Service Provider under paragraph (a) within the time specified by the AER in a notice provided to the Distribution Network Service Provider by the AER for that purpose.
Extension of time limit
(j)	If the AER is satisfied that amending a distribution determination under subparagraphs (e)(3) and (h) involves issues of such complexity or difficulty that the time limit fixed in paragraph (d) should be extended, the AER may extend that time limit by a further period of up to 60 business days, provided that it gives written notice to the Distribution Network Service Provider of that extension no later than 10 business days before the expiry of that time limit.
(k)	If the AER extends the time limit under paragraph (j), it must make available on its website a notice of that extension as soon as is reasonably practicable.
(l)	Subject to paragraph (n1), if the AER gives a written notice to the Distribution Network Service Provider stating that it requires information from an Authority in order to make a decision on an application made by the Distribution Network Service Provider under paragraph (a) then, for the purpose of calculating elapsed time, the period between when the AER gives that notice to the Distribution Network Service Provider and when the AER receives that information from that Authority is to be disregarded.
(m)	Subject to paragraph (n1), if the AER gives a written notice to the Distribution Network Service Provider stating that, in order to make a decision on an application made by the Distribution Network Service Provider under paragraph (a), it requires information from a judicial body or royal commission then, for the purpose of calculating elapsed time, the period between when the AER gives that notice to the Distribution Network Service Provider and when that information is made publicly available is to be disregarded.
(n)	Where the AER gives a notice to the Distribution Network Service Provider under paragraph (l) or (m), it must:
(1)	as soon as is reasonably practicable make available on its website a notice stating when the period referred to in paragraph (l) or (m), as the case may be, has commenced;

(3)	if the information specified in that notice is required from an Authority, promptly request that information from the relevant Authority.
(n1)	Paragraphs (l) and (m) do not apply if the AER gives the notice specified in those paragraphs to the Distribution Network Service Provider later than 10 business days before the expiry of the time limit fixed in paragraph (d).
Amendment of distribution determination
(o)	If the AER amends a distribution determination under paragraph (h), that amendment must take effect from the commencement of the next regulatory year. 
Part D	Negotiated distribution services
6.7	Negotiated distribution services
6.7.1	Principles relating to access to negotiated distribution services
The following principles constitute the Negotiated Distribution Service Principles:
(1)	the price for a negotiated distribution service should be based on the costs incurred in providing that service, determined in accordance with the principles and policies set out in the Cost Allocation Method for the relevant Distribution Network Service Provider;
(2)	subject to subparagraphs (3) and (4), the price for a negotiated distribution service should be at least equal to the cost that would be avoided by not providing the service but no more than the cost of providing it on a stand alone basis;
(3)	if the negotiated distribution service is the provision of a shared distribution service that:
(i)	exceeds the network performance requirements (if any) which that shared distribution service is required to meet under any jurisdictional electricity legislation; or
(ii)	exceeds the network performance requirements set out in schedules 5.1a and 5.1,
then the differential between the price for that service and the price for the shared distribution service which meets (but does not exceed) the network performance requirements under any jurisdictional electricity legislation or as set out in schedules 5.1a and 5.1 (as the case may be) should reflect the increase in the Distribution Network Service Provider's incremental cost of providing that service;
(4)	if the negotiated distribution service is the provision of a shared distribution service that does not meet (and does not exceed) the network performance requirements set out in schedules 5.1a and 5.1, the differential between the price for that service and the price for the shared distribution service which meets (but does not exceed) the network performance requirements set out in schedules 5.1a and 5.1 should reflect the cost the Distribution Network Service Provider would avoid by not providing that service;
(5)	the price for a negotiated distribution service must be the same for all Distribution Network Users unless there is a material difference in the costs of providing the negotiated distribution service to different Distribution Network Users or classes of Distribution Network Users;
(6)	the price for a negotiated distribution service should be subject to adjustment over time to the extent that the assets used to provide that service are subsequently used to provide services to another person, in which case the adjustment should reflect the extent to which the costs of that asset are being recovered through charges to that other person;
(7)	the price for a negotiated distribution service should be such as to enable the Distribution Network Service Provider to recover the efficient costs of complying with all regulatory obligations or requirements associated with the provision of the negotiated distribution service;
(8)	any access charges:
(A)	in respect of providing distribution network user access to negotiated distribution services which would have been negotiated distribution services regardless of the operation of clause 6.24.2(c) should be based on the costs reasonably incurred by the Distribution Network Service Provider in providing that access and, in the case of compensation referred to in clauses 5.5(f)(4)(ii) and (iii), on the revenue that is likely to be foregone and the costs that are likely to be incurred by a person referred to in those provisions where an event referred to in those provisions occurs; and
(B)	in respect of providing transmission network user access to negotiated distribution services which would have been treated as negotiated transmission services were it not for the operation of clause 6.24.2(c) should be based on the costs reasonably incurred by the Distribution Network Service Provider in providing that access and, in the case of compensation referred to in clauses 5.4A(h) - (j), on the revenue that is likely to be foregone and the costs that are likely to be incurred by a person referred to in those provisions where an event referred to in those provisions occurs;
(9)	the terms and conditions of access for a negotiated distribution service should be fair and reasonable and consistent with the safe and reliable operation of the power system in accordance with the Rules (for these purposes, the price for a negotiated distribution service is to be treated as being fair and reasonable if it complies with principles (1) to (7) of this clause);
(10)	the terms and conditions of access for a negotiated distribution service (including, in particular, any exclusions and limitations of liability and indemnities) must not be unreasonably onerous taking into account the allocation of risk between the Distribution Network Service Provider and the other party, the price for the negotiated distribution service and the costs to the Distribution Network Service Provider of providing the negotiated distribution service;
(11)	the terms and conditions of access for a negotiated distribution service should take into account the need for the service to be provided in a manner that does not adversely affect the safe and reliable operation of the power system in accordance with the Rules.
6.7.2	Determination of terms and conditions of access for negotiated distribution services
(a)	A Distribution Network Service Provider must comply with:
(1)	the provider’s negotiating framework; and
(2)	the provider’s Negotiated Distribution Service Criteria,
when the provider is negotiating the terms and conditions of access to negotiated distribution services.
(b)	The Distribution Network Service Provider must also comply with any other applicable requirements of the Rules, including the requirements of:
(1)	rules 5.3, 5.3A and 5.5, when negotiating for the provision of connection services and the associated connection service charges in respect of the provision of negotiated distribution services which would have been negotiated distribution services regardless of the operation of clause 6.24.2(c);
(2)	rules 5.3, 5.3A, when negotiating for the provision of connection services and the associated connection service charges in respect of the provision of negotiated distribution services which would have been treated as negotiated transmission services were it not for the operation of clause 6.24.2(c);
(3)	rule 5.5, when negotiating the use of system services charges and access charges to be paid to or by a Distribution Network User in respect of the provision of negotiated distribution services which would have been negotiated distribution services regardless of the operation of clause 6.24.2(c); and
(4)	rule 5.4A, when negotiating the use of system services charges and access charges to be paid to or by a Distribution Network User in respect of the provision of negotiated distribution services which would have been treated as negotiated transmission services were it not for the operation of clause 6.24.2(c).
6.7.3	Negotiating framework determination
The determination specifying requirements relating to the negotiating framework forming part of a distribution determination for a Distribution Network Service Provider is to set out requirements that are to be complied with in respect of the preparation, replacement, application or operation of its negotiating framework.
6.7.4	Negotiated Distribution Service Criteria determination
(a)	The determination by the AER specifying the Negotiated Distribution Service Criteria forming part of a distribution determination for a Distribution Network Service Provider is to set out the criteria that are to be applied:
(1)	by the provider in negotiating terms and conditions of access including:
(i)	the prices that are to be charged for the provision of negotiated distribution services by the provider for the relevant regulatory control period; or
(ii)	any access charges which are negotiated by the provider during that regulatory control period; and
(2)	by the AER in resolving an access dispute about terms and conditions of access including:
(i)	the price that is to be charged for the provision of a negotiated distribution service by the provider; or
(ii)	any access charges that are to be paid to or by the provider.
(b)	The Negotiated Distribution Service Criteria must give effect to and be consistent with the Negotiated Distribution Service Principles set out in clause 6.7.1.
6.7.5	Preparation of and requirements for negotiating framework for negotiated distribution services
(a)	A Distribution Network Service Provider must prepare a document (the negotiating framework) setting out the procedure to be followed during negotiations between that provider and any person (the Service Applicant or applicant) who wishes to receive a negotiated distribution service from the provider, as to the terms and conditions of access for the provision of the service.
(b)	The negotiating framework for a Distribution Network Service Provider must comply with and be consistent with:
(1)	the applicable requirements of the relevant distribution determination; and

See clause 6.7.3.
(2)	paragraph (c), which sets out the minimum requirements for a negotiating framework.
(c)	The negotiating framework for a Distribution Network Service Provider must specify:
(1)	a requirement for the provider and a Service Applicant to negotiate in good faith the terms and conditions of access to a negotiated distribution service; and
(2)	a requirement for the provider to provide all such commercial information a Service Applicant may reasonably require to enable that applicant to engage in effective negotiation with the provider for the provision of the negotiated distribution service, including the cost information described in subparagraph (3); and
(3)	a requirement for the provider:
(i)	to identify and inform a Service Applicant of the reasonable costs and/or the increase or decrease in costs (as appropriate) of providing the negotiated distribution service; and
(ii)	to demonstrate to a Service Applicant that the charges for providing the negotiated distribution service reflect those costs and/or the cost increment or decrement (as appropriate); and
(iii)	to have appropriate arrangements for assessment and review of the charges and the basis on which they are made; and
Note:
If (for example) a charge, or an element of a charge, is based on a customer's actual or assumed maximum demand, the assessment and review arrangements should allow for a change to the basis of the charge so that it more closely reflects the customer's load profile where a reduction or increase in maximum demand has been demonstrated.
(4)	a requirement for a Service Applicant to provide all commercial information the provider may reasonably require to enable the provider to engage in effective negotiation with that applicant for the provision of the negotiated distribution service; and
(5)	a requirement that negotiations with a Service Applicant for the provision of the negotiated distribution service be commenced and finalised within specified periods and a requirement that each party to the negotiations must make reasonable endeavours to adhere to the specified time limits; and
(6)	a process for dispute resolution which provides that all disputes as to the terms and conditions of access for the provision of negotiated distribution services are to be dealt with in accordance with the relevant provisions of the Law and the Rules for dispute resolution; and
(7)	the arrangements for payment by a Service Applicant of the provider's reasonable direct expenses incurred in processing the application to provide the negotiated distribution service; and
(8)	a requirement that the Distribution Network Service Provider determine the potential impact on other Distribution Network Users of the provision of the negotiated distribution service; and
(9)	a requirement that the Distribution Network Service Provider must notify and consult with any affected Distribution Network Users and ensure that the provision of negotiated distribution services does not result in non-compliance with obligations in relation to other Distribution Network Users under the Rules; and
(10)	a requirement that the Distribution Network Service Provider publish the results of negotiations on its website.
(d)	Notwithstanding the foregoing, the negotiating framework must not be inconsistent with any of the requirements of:
(1)	rules 5.3, 5.3A and 5.5 insofar as the negotiating framework applies to negotiated distribution services which would have been negotiated distribution services regardless of the operation of clause 6.24.2(c); and
(2)	rules 5.3, 5.3A and 5.4A insofar as the negotiating framework applies to negotiated distribution services which would have been treated as negotiated transmission services were it not for the operation of clause 6.24.2(c),
and any other relevant provisions of this Chapter 6 and, in the event of any inconsistency, those requirements prevail.
(e)	Each Distribution Network Service Provider and Service Applicant who is negotiating for the provision of a negotiated distribution service by the provider must comply with the requirements of the negotiating framework in accordance with its terms.
6.7.6	Confidential information
(a)	Commercial information to be provided to a Service Applicant in accordance with clause 6.7.5(c)(2):
(1)	does not include confidential information provided to the Distribution Network Service Provider by another person; and
(2)	may be provided subject to a condition that the Service Applicant must not provide any part of that commercial information to any other person without the consent of the Distribution Network Service Provider.
(b)	Commercial information to be provided to a Distribution Network Service Provider in accordance with clause 6.7.5(c)(4):
(1)	does not include confidential information provided to a Service Applicant by another person; and
(2)	may be provided subject to a condition that the provider must not provide any part of that commercial information to any other person without the consent of the Service Applicant.
Part DA	Connection policies

(b)	The proposed connection policy:
(1)	must be consistent with:
(i)	the connection charge principles; and

(2)	the allocation of costs must be determined according to the substance of a transaction or event rather than its legal form;
(3)	only the following costs may be allocated to a particular category of distribution services:
(i)	costs which are directly attributable to the provision of those services;
(ii)	costs which are not directly attributable to the provision of those services but which are incurred in providing those services, in which case such costs must be allocated to the provision of those services using an appropriate allocator which should:
(A)	except to the extent the cost is immaterial or a causal based method of allocation cannot be established without undue cost and effort, be causation based; and
(B)	to the extent the cost is immaterial or a causal based method of allocation cannot be established without undue cost and effort, be an allocator that accords with a well accepted cost allocation method;
(4)	any cost allocation method which is used, the reasons for using that method and the numeric quantity (if any) of the chosen allocator must be clearly described;
(5)	the same cost must not be allocated more than once;

(f)	A Distribution Network Service Provider may, with the AER's approval, amend its Cost Allocation Method from time to time but:
(1)	the amendment:
(i)	may be approved on condition that the Distribution Network Service Provider agree to incorporate into the amendment specified additional changes to the Cost Allocation Method the AER reasonably considers necessary or desirable as a result of the amendment as submitted; and
(ii)	if approved on such a condition, does not take effect unless and until the Distribution Network Service Provider notifies the AER of its agreement; and
(2)	if 6 months elapse from the date of the submission of the amendment and the AER has not notified the Distribution Network Service Provider within that period of its approval or refusal to approve the amendment, the amendment is, at the end of that period, conclusively presumed to have been unconditionally approved.
(g)	A Distribution Network Service Provider must amend its Cost Allocation Method where the amendment is required by the AER to take into account any change to the Cost Allocation Guidelines, but the amendment only comes into effect:
(1)	on the date that the AER approves that amendment, or 3 months after the submission of the amendment, whichever is the earlier; and
(2)	subject to additional changes to the Cost Allocation Method (if any) the AER reasonably considers necessary or desirable as a result of the amendment and notifies to the Distribution Network Service Provider before the amendment takes effect.

Note:
Clause 11.14.5 will have a bearing on the application of these guidelines in certain cases.
(b)	The Distribution Ring-Fencing Guidelines may include, but are not limited to:
(1)	provisions defining the need for and extent of:
(i)	legal separation of the entity through which a Distribution Network Service Provider provides network services from any other entity through which it conducts business; and
(ii)	the establishment and maintenance of consolidated and separate accounts for standard control services, alternative control services and other services provided by the Distribution Network Service Provider; and
(iii)	allocation of costs between standard control services, alternative control services and other services provided by the Distribution Network Service Provider; and

Part I	Distribution Pricing Rules
6.18	Distribution Pricing Rules
6.18.1	Application of this Part
This Part applies to tariffs and tariff classes related to direct control services.
6.18.1A	Tariff structure statement
(a)	A tariff structure statement of a Distribution Network Service Provider must include the following elements:
(1)	the tariff classes into which retail customers for direct control services will be divided during the relevant regulatory control period;
(2)	the policies and procedures the Distribution Network Service Provider will apply for assigning retail customers to tariffs or reassigning retail customers from one tariff to another (including any applicable restrictions);
(3)	the structures for each proposed tariff; 
(4)	the charging parameters for each proposed tariff; and
(5)	a description of the approach that the Distribution Network Service Provider will take in setting each tariff in each pricing proposal of the Distribution Network Service Provider during the relevant regulatory control period in accordance with clause 6.18.5.
(b)	A tariff structure statement must comply with the pricing principles for direct control services.
(c)	A Distribution Network Service Provider must comply with the tariff structure statement approved by the AER and any other applicable requirements in the Rules, when the provider is setting the prices that may be charged for direct control services.
(d)	Subject to clause 6.18.1B, a tariff structure statement may not be amended during a regulatory control period.
Note
Rule 6.13 still applies in relation to a tariff structure statement because that rule deals with the revocation and substitution of a distribution determination (which includes a tariff structure statement) as opposed to its amendment.
(e)	A tariff structure statement must be accompanied by an indicative pricing schedule which sets out, for each tariff for each regulatory year of the regulatory control period, the indicative price levels determined in accordance with the tariff structure statement.
6.18.1B	Amending a tariff structure statement with the AER's approval
(a)	No later than nine months before the start of a regulatory year (other than the first regulatory year of a regulatory control period) (relevant regulatory year), a Distribution Network Service Provider may request the AER to approve an amendment to its current tariff structure statement.
(b)	A request for an amendment to a tariff structure statement under paragraph (a) must include:
(1)	the proposed amended tariff structure statement;
(2)	a description of the event that has occurred to cause the Distribution Network Service Provider to seek an amendment to its current tariff structure statement and why the event:
(i)	was beyond the reasonable control of the Distribution Network Service Provider; and
(ii)	could not reasonably have been foreseen by the Distribution Network Service Provider at the time its current tariff structure statement was approved by the AER.
(3)	a description and justification of the differences between the proposed amended tariff structure statement and the Distribution Network Service Provider's current tariff structure statement;
(4)	a description of how the differences referred to in sub-paragraph (3) would impact the other elements of the tariff structure statement;
(5)	a description of how the proposed amended tariff structure statement would better comply with the pricing principles for direct control services than the current tariff structure statement; and
(6)	a description of how the Distribution Network Service Provider has engaged with retail customers and retailers in developing the proposed amended tariff structure statement and has sought to address any relevant concerns identified as a result of that engagement.
(c)	The AER must, on receipt of a Distribution Network Service Provider's request for an amendment to its tariff structure statement, publish the request.
(d)	The AER must approve the request for an amendment to a tariff structure statement under paragraph (a) if the Distribution Network Service Provider demonstrates to the reasonable satisfaction of the AER that:
(1)	an event has occurred that:
(i)	was beyond the reasonable control of the Distribution Network Service Provider; and
(ii)	could not reasonably have been foreseen by the Distribution Network Service Provider at the time its current tariff structure statement was approved by the AER; and
(2)	as a result of the event referred to in sub-paragraph (1), the proposed amended tariff structure statement would, or would be likely to, materially better comply with the pricing principles for direct control services than the Distribution Network Service Provider's current tariff structure statement.
(e)	No later than four months before the start of the relevant regulatory year, the AER must either approve or refuse to approve the request for an amendment to a tariff structure statement under paragraph (a) and set out reasons for its decision.
(f)	If the AER refuses to approve the request for an amendment to a tariff structure statement under paragraph (a), the current tariff structure statement will apply for the relevant regulatory year and, subject to any subsequent amendment approved under this clause 6.18.1B, the remainder of the regulatory control period.
Note
Rule 6.13 still applies in relation to a tariff structure statement because that rule deals with the revocation and substitution of a distribution determination (which includes a tariff structure statement) as opposed to its amendment.
6.18.1C	Sub-threshold tariffs
(a)	No later than four months before the start of a regulatory year (other than the first regulatory year of a regulatory control period), a Distribution Network Service Provider may notify the AER, affected retailers and affected retail customers of a new proposed tariff (a relevant tariff) that is determined otherwise than in accordance with the Distribution Network Service Provider's current tariff structure statement, if both of the following are satisfied:
(1)	the Distribution Network Service Provider's forecast revenue from the relevant tariff during each regulatory year in which the tariff is to apply is no greater than 0.5 per cent of the Distribution Network Service Provider's annual revenue requirement for that regulatory year (the individual threshold); and 
(2)	the Distribution Network Service Provider's forecast revenue from the relevant tariff, as well as from all other relevant tariffs, during each regulatory year in which those tariffs are to apply is no greater than one per cent of the Distribution Network Service Provider's annual revenue requirement for that regulatory year (the cumulative threshold).
(b)	Notwithstanding any other provision in the Rules to the contrary, a relevant tariff notified by the Distribution Network Service Provider in accordance with paragraph (a) is, for the remainder of the regulatory control period in which the notification is given:
(1)	not required to comply with the pricing principles for direct control services; and
(2)	for the purposes of the submission and approval of a pricing proposal, deemed to comply with the Distribution Network Service Provider's current tariff structure statement,
unless, at any point in time after the notification of the relevant tariff is given under paragraph (a) (the post-notification point), either the individual threshold or the cumulative threshold (in each case calculated using actual rather than forecast revenue) are exceeded by virtue of the amount of revenue that is attributable to the relevant tariff, in which case sub-paragraphs (1) and (2) cease to apply to the relevant tariff in relation to the regulatory years that commence after the post-notification point.
(c)	Where sub-paragraphs (b)(1) and (2) cease to apply to a relevant tariff in accordance with paragraph (b), then sub-paragraphs (b)(1) and (2) will be taken to continue to apply to other relevant tariffs that were notified before the post-notification point, but only to the extent that those sub-paragraphs would apply if the first-mentioned relevant tariff were not a relevant tariff.
6.18.2	Pricing proposals
(a)	A Distribution Network Service Provider must:
(1)	submit to the AER, as soon as practicable, and in any case within 15 business days, after publication of the distribution determination, a pricing proposal (the initial pricing proposal) for the first regulatory year of the regulatory control period; and
(2)	submit to the AER, at least 3 months before the commencement of the second and each subsequent regulatory year of the regulatory control period, a further pricing proposal (an annual pricing proposal) for the relevant regulatory year.
(b)	A pricing proposal must:
(1)	[Deleted]; 
(2)	set out the proposed tariffs for each tariff class that is specified in the Distribution Network Service Provider's tariff structure statement for the relevant regulatory control period; 
(3)	set out, for each proposed tariff, the charging parameters and the elements of service to which each charging parameter relates; 
(4)	set out, for each tariff class related to standard control services, the expected weighted average revenue for the relevant regulatory year and also for the current regulatory year; 
(5)	set out the nature of any variation or adjustment to the tariff that could occur during the course of the regulatory year and the basis on which it could occur; 
(6)	set out how designated pricing proposal charges are to be passed on to customers and any adjustments to tariffs resulting from over or under recovery of those charges in the previous regulatory year; 
(6A)	set out how jurisdictional scheme amounts for each approved jurisdictional scheme are to be passed on to customers and any adjustments to tariffs resulting from over or under recovery of those amounts; 
(6B)	describe how each approved jurisdictional scheme that has been amended since the last jurisdictional scheme approval date meets the jurisdictional scheme eligibility criteria; 
(7)	demonstrate compliance with the Rules and any applicable distribution determination, including the Distribution Network Service Provider's tariff structure statement for the relevant regulatory control period; 
(7A)	demonstrate how each proposed tariff is consistent with the corresponding indicative pricing levels for the relevant regulatory year as set out in the relevant indicative pricing schedule, or explain any material differences between them; and
(8)	describe the nature and extent of change from the previous regulatory year and demonstrate that the changes comply with the Rules and any applicable distribution determination.
(c)	The AER must on receipt of a pricing proposal from a Distribution Network Service Provider publish the proposal.
(d)	At the same time as a Distribution Network Service Provider submits a pricing proposal under paragraph (a), the Distribution Network Service Provider must submit to the AER a revised indicative pricing schedule which sets out, for each tariff and for each of the remaining regulatory years of the regulatory control period, the indicative price levels determined in accordance with the Distribution Network Service Provider's tariff structure statement for that regulatory control period and updated so as to take into account that pricing proposal.
(e)	Where the Distribution Network Service Provider submits an annual pricing proposal, the revised indicative pricing schedule referred to in paragraph (d) must also set out, for each relevant tariff under clause 6.18.1C, the indicative price levels for that relevant tariff for each of the remaining regulatory years of the regulatory control period, updated so as to take into account that pricing proposal.
6.18.3	Tariff classes
(a)	[Deleted].
(b)	Each customer for direct control services must be a member of 1 or more tariff classes.
(c)	Separate tariff classes must be constituted for retail customers to whom standard control services are supplied and retail customers to whom alternative control services are supplied (but a customer for both standard control services and alternative control services may be a member of 2 or more tariff classes).
(d)	A tariff class must be constituted with regard to:
(1)	the need to group retail customers together on an economically efficient basis; and
(2)	the need to avoid unnecessary transaction costs.
6.18.4	Principles governing assignment or re-assignment of retail customers to tariff classes and assessment and review of basis of charging
(a)	In formulating provisions of a distribution determination governing the assignment of retail customers to tariff classes or the re-assignment of retail customers from one tariff class to another, the AER must have regard to the following principles:
(1)	retail customers should be assigned to tariff classes on the basis of one or more of the following factors:
(i)	the nature and extent of their usage;
(ii)	the nature of their connection to the network;
(iii)	whether remotely-read interval metering or other similar metering technology has been installed at the retail customer's premises as a result of a regulatory obligation or requirement;
(2)	retail customers with a similar connection and usage profile should be treated on an equal basis;
(3)	however, retail customers with micro-generation facilities should be treated no less favourably than retail customers without such facilities but with a similar load profile;
(4)	a Distribution Network Service Provider's decision to assign a customer to a particular tariff class, or to re-assign a customer from one tariff class to another should be subject to an effective system of assessment and review.
Note:
If (for example) a customer is assigned (or reassigned) to a tariff class on the basis of the customer's actual or assumed maximum demand, the system of assessment and review should allow for the reassignment of a customer who demonstrates a reduction or increase in maximum demand to a tariff class that is more appropriate to the customer's load profile.
(b)	If the charging parameters for a particular tariff result in a basis of charge that varies according to the usage or load profile of the customer, a distribution determination must contain provisions for an effective system of assessment and review of the basis on which a customer is charged.
6.18.5	Pricing principles
Network pricing objective
(a)	The network pricing objective is that the tariffs that a Distribution Network Service Provider charges in respect of its provision of direct control services to a retail customer should reflect the Distribution Network Service Provider's efficient costs of providing those services to the retail customer.
Application of the pricing principles
(b)	Subject to paragraph (c), a Distribution Network Service Provider's tariffs must comply with the pricing principles set out in paragraphs (e) to (j).
(c)	A Distribution Network Service Provider's tariffs may vary from tariffs which would result from complying with the pricing principles set out in paragraphs (e) to (g) only:
(1)	to the extent permitted under paragraph (h); and
(2)	to the extent necessary to give effect to the pricing principles set out in paragraphs (i) to (j).
(d)	A Distribution Network Service Provider must comply with paragraph (b) in a manner that will contribute to the achievement of the network pricing objective.
Pricing principles
(e)	For each tariff class, the revenue expected to be recovered must lie on or between:
(1)	an upper bound representing the stand alone cost of serving the retail customers who belong to that class; and
(2)	a lower bound representing the avoidable cost of not serving those retail customers.
(f)	Each tariff must be based on the long run marginal cost of providing the service to which it relates to the retail customers assigned to that tariff with the method of calculating such cost and the manner in which that method is applied to be determined having regard to:
(1)	the costs and benefits associated with calculating, implementing and applying that method as proposed;
(2)	the additional costs likely to be associated with meeting demand from retail customers that are assigned to that tariff at times of greatest utilisation of the relevant part of the distribution network; and
(3)	the location of retail customers that are assigned to that tariff and the extent to which costs vary between different locations in the distribution network.
(g)	The revenue expected to be recovered from each tariff must:
(1)	reflect the Distribution Network Service Provider's total efficient costs of serving the retail customers that are assigned to that tariff;
(2)	when summed with the revenue expected to be received from all other tariffs, permit the Distribution Network Service Provider to recover the expected revenue for the relevant services in accordance with the applicable distribution determination for the Distribution Network Service Provider; and

(c)	A dispute between a Distribution Network Service Provider and a Connection Applicant about matters referred to in clause 5.5(f) or clause 5.5(h) is an access dispute for the purposes of Part 10 of the Law.
6.22.2	Determination of dispute
(a)	In determining an access dispute about terms and conditions of access to a direct control service, the AER must apply:
(1)	in relation to price, the Distribution Network Service Provider's approved pricing proposal and the Distribution Network Service Provider's tariff structure statement or, in respect of the Distribution Network Service Provider's transmission standard control services in respect of which the AER has made a determination under clause 6.25(b) that pricing in respect of those services should be regulated under Part J of Chapter 6A through the application of rule 6.26, the Distribution Network Service Provider's approved pricing methodology;
(2)	in relation to other terms and conditions, Chapters 4, 5, this Chapter 6 and Chapter 7 and any other applicable regulatory instrument; and
(3)	in relation to all terms and conditions of access (including price) the decisions of AEMO or the AER where those decisions relate to those terms and conditions and are made under Chapters 4, 5, this Chapter 6 and Chapter 7.
(b)	In determining an access dispute about the terms and conditions of access to a direct control service, the AER may:
(1)	have regard to other matters the AER considers relevant; and
(2)	hear evidence or receive submissions from AEMO about power system security and from Distribution Network Users who may be adversely affected.
Note:
Section 130 of the Law requires the AER, in making an access determination, to give effect to a network revenue or pricing determination applicable to the services that are the subject of the dispute even though the determination may not have been in force when the dispute arose.
(c)	In determining an access dispute about terms and conditions of access to a negotiated distribution service, the AER must apply:
(1)	in relation to price (including access charges), the Negotiated Distribution Service Criteria that are applicable to the dispute in accordance with the relevant distribution determination; and
(2)	in relation to other terms and conditions, the Negotiated Distribution Service Criteria that are applicable to the dispute and Chapters 4, 5, this Chapter 6 and Chapter 7 of the Rules; and
(3)	in relation to all terms and conditions of access (including price) the decisions of AEMO or the AER where those decisions relate to those terms and conditions and are made under Chapters 4, 5, this Chapter 6 and Chapter 7 of the Rules;
and must have regard:
(4)	to the relevant negotiating framework prepared by the Distribution Network Service Provider and approved by the AER.
(d)	In determining an access dispute about the terms and conditions of access to a negotiated distribution service, the AER may:
(1)	have regard to other matters the AER considers relevant; and
(2)	hear evidence or receive submissions from AEMO and Distribution Network Users notified and consulted under the Distribution Network Service Provider's negotiating framework.
(e)	In determining an access dispute about access charges, or involving access charges, the AER must give effect to the following principle:
Access charges should be based on the costs reasonably incurred by the Distribution Network Service Provider in providing distribution network user access and, where they consist of compensation referred to in clause 5.5(f)(4)(ii) and (iii), on the revenue that is likely to be foregone and the costs that are likely to be incurred by a person referred to in those provisions where an event referred to in those provisions occurs.
6.22.3	Termination of access dispute without access determination
(a)	If the AER considers that an access dispute could be effectively resolved by some means other than an access determination, the AER may give the parties to the dispute notice of the alternative means of resolving the dispute.
(b)	The giving of such a notice is a specified dispute termination circumstance for the purposes of section 131(3) of the Law.
Note:
It follows that the AER may exercise its power to terminate the dispute without making an access determination (See section 131(1)(d) of the Law).
Part M	Separate disclosure of transmission and distribution charges
6.23	Separate disclosure of transmission and distribution charges
(a)	A Distribution Customer:
(1)	with a load greater than 10MW or 40GWh per annum; or
(2)	with metering equipment capable of capturing relevant transmission and distribution system usage data,
may make a request (a TUOS/DUOS disclosure request) to a Distribution Network Service Provider to provide the Distribution Customer with a statement (a TUOS/DUOS disclosure statement) identifying the separate components of the designated pricing proposal charges and distribution use of system charges comprised in the charges for electricity supplied to the Distribution Customer's connection points.
(b)	Within 10 business days of receipt of a TUOS/DUOS disclosure request, a Distribution Network Service Provider must notify the Distribution Customer of the estimated charge (including details of how the charge is calculated) for providing the TUOS/DUOS disclosure statement. The charge must be no greater than the reasonable costs directly incurred by the Distribution Network Service Provider in preparing the statement for the Distribution Customer.
(c)	If the Distribution Customer advises the Distribution Network Service Provider within 20 business days of receipt of the notice referred to in paragraph (b) that it still requires the requested TUOS/DUOS disclosure statement, the Distribution Network Service Provider must prepare the statement and provide it to the Distribution Customer within 20 business days of being so advised. The TUOS/DUOS disclosure statement must include detailed information on the method used to determine the distribution use of system charges and the allocation of the designated pricing proposal charges to the Distribution Customer for electricity supplied to its connection points. The information must be sufficient to allow the Distribution Customer to assess the impact on its network charges of a change in its network use.
(d)	The TUOS/DUOS disclosure statement must also separately identify the amounts that have been allocated to the Distribution Customer's connection points under Part J of Chapter 6A in respect of each of the categories of prescribed transmission services, where the Distribution Customer requests this information.
(e)	Where the Distribution Customer requests the information referred to in paragraph (d), the Distribution Network Service Provider must separately identify the component of the charge notified under paragraph (b) that relates to the provision of the additional information.
(f)	Each Distribution Network Service Provider must publish information annually disclosing the designated pricing proposal charges and distribution use of system charges for each of the classes of Distribution Customers identified for this purpose by the Distribution Network Service Provider, or as required by the AER.
Part N	Dual Function Assets
6.24	Dual Function Assets
6.24.1	Application of this Part
This Part applies to Distribution Network Service Providers which own, control or operate both a distribution system and a dual function asset.
6.24.2	Dual Function Assets
Subject to rule 6.26, for the purposes of Chapters 6 and 6A:
(a)	any part of a network owned, operated or controlled by a Distribution Network Service Provider which operates between 66 kV and 220 kV and which operates in parallel, and provides support, to the higher voltage transmission network is deemed to be a dual function asset;
(b)	any service that is provided by a Distribution Network Service Provider by means of, or in connection with, the Distribution Network Service Provider’s dual function assets that, but for this Part, would be a prescribed transmission service for the purposes of Chapter 6A is deemed to be a standard control service;
(c)	any service that is provided by a Distribution Network Service Provider by means of, or in connection with, the Distribution Network Service Provider’s dual function assets that, but for this Part, would be a negotiated transmission service under Chapter 6A is deemed to be a negotiated distribution service; and
(d)	references to prescribed transmission services do not include a service provided by means of, or in connection with, a dual function asset.
6.25	AER determination of applicable pricing regime for Dual Function Assets
(a)	A Distribution Network Service Provider which owns, controls or operates dual function assets must advise the AER at least 32 months prior to the end of the current regulatory control period of the value of that Distribution Network Service Provider's dual function assets which provide standard control services that would be prescribed transmission services were it not for the operation of clause 6.24.2 (referred to as transmission standard control services). The value to be advised is the value ascribed to the relevant dual function assets in the relevant Distribution Network Service Provider's regulatory asset base as at the start of the regulatory year which commences 36 months prior to the end of the current regulatory control period.
(b)	The AER must review the information provided under paragraph (a) and determine, in accordance with clause 6.8.1, whether the value of that Distribution Network Service Provider's dual function assets which provide transmission standard control services comprise such a material proportion of that Distribution Network Service Provider's regulatory asset base that pricing in respect of those services should be regulated under Part J of Chapter 6A through the application of rule 6.26. 
(c)	In making its determination under paragraph (b) the AER must consider:
(1)	whether regulating the pricing of the transmission standard control services provided by a Distribution Network Service Provider's dual function assets:
(i)	under Part I of Chapter 6 as though they were prescribed distribution services; rather than
(ii)	under Part J of Chapter 6A as though they were prescribed transmission services,
will result in materially different prices for Distribution Customers (including those connected directly to the relevant dual function assets and those connected to other distribution networks);

(a)	This rule 6.26 applies if the AER has determined under rule 6.25(b) that pricing in respect of transmission standard control services provided by a Distribution Network Service Provider's dual function assets should be regulated under Part J of Chapter 6A.
(b)	The AER must, for the purposes of the distribution determination for the relevant Distribution Network Service Provider, divide the revenue calculated under Part C of Chapter 6 into the following two portions:
(1)	a portion relevant to the Distribution Network Service Provider's transmission standard control services provided by its dual function assets. This portion is defined as its transmission standard control service revenue; and
(2)	a portion relevant to the other standard control services provided by the Distribution Network Service Provider. This portion is defined as its distribution standard control service revenue,
based on the Distribution Network Service Provider’s approved Cost Allocation Method.
(c)	The relevant Distribution Network Service Provider must submit a proposed pricing methodology to the AER in respect of its transmission standard control service revenue as if it were a Transmission Network Service Provider as part of its regulatory proposal under Chapter 6, and Part E of Chapter 6A applies in respect of that pricing methodology (with the necessary changes).
(d)	The AER and the relevant Distribution Network Service Provider must apply and comply with all aspects of Part J of Chapter 6A instead of, and to the exclusion of, Parts I, J and K of Chapter 6 in respect of the dual function assets which provide transmission standard control services, subject to the following:
(1)	for the purposes of Part J of Chapter 6A:
(i)	the dual function assets are relevantly deemed to be transmission network assets which provide prescribed transmission services;
(ii)	the Distribution Network Service Provider which owns, controls or operates the relevant dual function assets is relevantly deemed to be a Transmission Network Service Provider;
(2)	the maximum allowed revenue referred to in clause 6A.22.1 is taken to be the transmission standard control service revenue;

(4)	references to "transmission determination" are to be read as references to the relevant "distribution determination", with the AER being required to include in the distribution determination a decision to approve a proposed pricing methodology in relation to the transmission standard control services provided by the relevant dual function assets; and
(5)	if there is no previous method to establish prices under clause 6A.24.3(b)(3), the relevant Distribution Network Service Provider must apply the pricing methodology of the largest Transmission Network Service Provider operating in the participating jurisdiction in which that Distribution Network Service Provider operates the relevant dual function assets.
(e)	The pricing rules in Part I of Chapter 6 are to be applied to the Distribution Network Service Provider's distribution standard control service revenue.
Part O	Annual Benchmarking Report
6.27	Annual Benchmarking Report

Schedule 6.2	Regulatory Asset Base
S6.2.1	Establishment of opening regulatory asset base for a regulatory control period
(a)	Application of this clause
This clause S6.2.1
(1)	applies to the establishment of the value of the regulatory asset base for a distribution system as at the beginning of a regulatory control period on the roll forward of the regulatory asset base to that regulatory control period from the previous regulatory control period; and
(2)	also applies to the establishment of the value of the regulatory asset base for a distribution system as at the beginning of a regulatory control period where the distribution system was not immediately before that time the subject of a building block determination.
(b)	Roll forward model to comply with this clause
The values to be used for completing the roll forward model must be established in accordance with this clause and clauses S6.2.2 and S6.2.3.
(c)	Distribution systems of specific providers
(1)	In the case of a distribution system owned, controlled or operated by one of the following Distribution Network Service Providers as at the commencement of this schedule, the value of the regulatory asset base for that distribution system as at the beginning of that first regulatory year must be determined by rolling forward the regulatory asset base for that distribution system, as set out in the table below, in accordance with this schedule:

Jurisdiction	Distribution Network Service Provider	Regulatory Asset Base ($m)	
Australian Capital Territory	ActewAGL	510.54 (as at 1 July 2004 in July 2004 dollars)	
New South Wales	Country Energy	2,440 (as at 1 July 2004 in July 2004 dollars)	
	EnergyAustralia	4,116 (as at 1 July 2004 in July 2004 dollars)	
	Integral Energy	2,283 (as at 1 July 2004 in July 2004 dollars)	
Queensland	ENERGEX	4,308.1 (as at 1 July 2005 in July 2005 dollars)	
	Ergon Energy	4,198.2 (as at 1 July 2005 in July 2005 dollars) but, if the Queensland Competition Authority nominates a different amount in writing to the AER, the regulatory asset base is the amount so nominated.	
South Australia	ETSA Utilities	2,466 (as at 1 July 2005 in December 2004 dollars)	
Tasmania	Aurora Energy	981.108 (as at 1 January 2008 in July 2006 dollars)	
Victoria	AGL Electricity	578.4 (as at 1 January 2006 in July 2004 dollars)	
	Citipower	990.9 (as at 1 January 2006 in July 2004 dollars)	
	Powercor	1,626.5 (as at 1 January 2006 in July 2004 dollars)	
	SP AusNet	1,307.2 (as at 1 January 2006 in July 2004 dollars)	
	United Energy	1,220.3 (as at 1 January 2006 in July 2004 dollars)	

(2)	The values in the table above are to be adjusted for the difference between:
(i)	any estimated capital expenditure that is included in those values for any part of a previous regulatory control period; and
(ii)	the actual capital expenditure for that part of the previous regulatory control period.
This adjustment must also remove any benefit or penalty associated with any difference between the estimated and actual capital expenditure.
(3)	When rolling forward a regulatory asset base under subparagraph (1), the AER must take into account the derivation of the values in the above table from past regulatory decisions and the consequent fact that they relate only to the regulatory asset base identified in those decisions.
(d)	Other distribution systems
(1)	This paragraph (d) applies to a distribution system not referred to in paragraphs (c) when standard control services that are provided by means of, or in connection with, that system are to be regulated under a building block determination.
(2)	The value of the regulatory asset base for that distribution system as at the beginning of the first regulatory year of the first regulatory control period for the relevant Distribution Network Service Provider is the prudent and efficient value of the assets that are used by the provider to provide those standard control services (but only to the extent that they are used to provide such services), as determined by the AER. In determining this value, the AER must have regard to the matters referred to in clause S6.2.2.
(3)	The value of the regulatory asset base for that distribution system as at the beginning of the first regulatory year of any subsequent regulatory control period must be determined by rolling forward the value of the regulatory asset base for that distribution system as at the beginning of the first regulatory year of the first regulatory control period in accordance with this schedule.
(e)	Method of adjustment of value of regulatory asset base
Except as otherwise provided in paragraph (c) or (d) and subject to paragraph (g), the value of the regulatory asset base for a distribution system as at the beginning of the first regulatory year of a regulatory control period must be calculated by adjusting the value (the previous value) of the regulatory asset base for that distribution system as at the beginning of the first regulatory year of the immediately preceding regulatory control period (the previous control period) as follows:
(1)	The previous value of the regulatory asset base must be:
(i)	increased by the amount of all capital expenditure incurred during the previous control period, including any capital expenditure determined for that period under clause 6.6A.2(e)(1)(i) in relation to contingent projects where the distribution determination has been amended by the AER in accordance with clause 6.6A.2(h) (regardless of whether such capital expenditure is above or below the forecast capital expenditure for the period that is adopted for the purposes of the distribution determination (if any) for that period); and
(ii)	reduced by the amount of any capital expenditure that has been recovered by way of a pass through under clause 6.6.1 where the amount of that capital expenditure would otherwise have been included in the value of the regulatory asset base.
(2)	The previous value of the regulatory asset base must be increased by the amount of the estimated capital expenditure approved by the AER for any part of the previous control period for which actual capital expenditure is not available, including any capital expenditure in relation to contingent projects where the total revenue requirement has been amended by the AER in accordance with clause 6.6A.2(h).
(3)	The previous value of the regulatory asset base must be adjusted for the difference between:
(i)	the estimated capital expenditure for any part of a previous regulatory control period where that estimated capital expenditure has been included in that value; and
(ii)	the actual capital expenditure for that part of the previous regulatory control period.
This adjustment must also remove any benefit or penalty associated with any difference between the estimated and actual capital expenditure.
(4)	The previous value of the regulatory asset base must only be increased by actual or estimated capital expenditure to the extent that all such capital expenditure is properly allocated to the provision of standard control services in accordance with the Cost Allocation Method for the relevant Distribution Network Service Provider.
(5)	The previous value of the regulatory asset base must be reduced by the amount of depreciation of the regulatory asset base during the previous regulatory control period, calculated in accordance with the distribution determination for that period.
(6)	The previous value of the regulatory asset base must be reduced by the disposal value of any asset where that asset has been disposed of during the previous regulatory control period.
(7)	The previous value of the regulatory asset base must be reduced by the value of an asset where the asset was previously used to provide standard control services (or their equivalent under the previous regulatory system) but, as a result of a change to the classification of a particular service under Part B, is not to be used for that purpose for the relevant regulatory control period.
(8)	The previous value of the regulatory asset base may be increased by the value of an asset to which this subparagraph applies to the extent that:
(i)	the AER considers the asset to be reasonably required to achieve one or more of the capital expenditure objectives; and
(ii)	the value of the asset has not been otherwise recovered.
This subparagraph applies to an asset that:
(i)	was not used to provide standard control services (or their equivalent under the previous regulatory system) in the previous regulatory control period but, as a result of a change to the classification of a particular service under Part B, is to be used for that purpose for the relevant regulatory control period; or
(ii)	was never previously used to provide standard control services (or their equivalent under the previous regulatory system) but is to be used for that purpose for the relevant regulatory control period.
(f)	An increase or reduction in the value of the regulatory asset base under subparagraph (7) or (8) of paragraph (e) is to be based on the portion of the value of the asset properly allocated, or formerly properly allocated, to standard control services in accordance with the principles and policies set out in the Cost Allocation Method for the relevant Distribution Network Service Provider. The value of the relevant asset is taken to be its value as shown in independently audited and published accounts.
(g)	The previous value of the regulatory asset base must be reduced by any amount determined by the AER in accordance with clause S6.2.2A(f), (i) or (j).
S6.2.2	Prudency and efficiency of capital expenditure
In determining the prudency or efficiency of capital expenditure under clause S6.2.1(d)(2), the AER must have regard to the following:
(1)	the need to provide a reasonable opportunity for the relevant Distribution Network Service Provider to recover the efficient costs of complying with all applicable regulatory obligations or requirements associated with the provision of standard control services;
(2)	the need to provide effective incentives to the Distribution Network Service Provider to promote economic efficiency in the provision of standard control services;
(3)	whether the relevant project in respect of which capital expenditure was made was evaluated against, and satisfied, the regulatory investment test for transmission or the regulatory investment test for distribution (as the case may be);
(4)	whether the Distribution Network Service Provider undertook the capital expenditure in a manner consistent with good business practice and so as to practicably achieve the lowest sustainable cost of delivering the standard control services to be provided as a consequence of that capital expenditure;
(5)	the desirability of minimising investment uncertainty for the Distribution Network Service Provider;
(6)	the need to provide incentives to the Distribution Network Service Provider to avoid undertaking inefficient capital expenditure;
(7)	the value of the relevant asset as shown in independently audited and published accounts.
In determining the prudency or efficiency of capital expenditure the AER must only take into account information and analysis that the Distribution Network Service Provider could reasonably be expected to have considered or undertaken at the time that it undertook the relevant capital expenditure.
S6.2.2A	Reduction for inefficient past capital expenditure
(a)	Prior to making a decision on the regulatory asset base for a distribution system as required by clause 6.12.1(6), the AER may determine under this clause S6.2.2A that the amount of capital expenditure as a result of which the previous value of the regulatory asset base would otherwise be increased in accordance with clause S6.2.1(e) should be reduced.
(a1)	for the purposes of this clause S6.2.2A, "review period" means:
(1)	the previous control period (excluding the last two regulatory years of that previous control period); and
(2)	the last two regulatory years of the regulatory control period preceding the previous control period.
(b)	The AER may only make a determination under paragraph (a) if any of the following requirements is satisfied:
(1)	the requirement set out in paragraph (c) (the overspending requirement);
(2)	the requirement set out in paragraph (d) (the margin requirement); or
(3)	the requirement set out in paragraph (e) (the capitalisation requirement).
(c)	The overspending requirement is satisfied where the sum of all capital expenditure incurred during the review period exceeds the sum of:
(1)	the forecast capital expenditure accepted or substituted by the AER for the review period as such forecast capital expenditure has been adjusted in accordance with clauses 6.6.5(f) and 6.6A.2(h); and
(2)	any capital expenditure that is recovered by way of such part of an approved pass through amount as is permitted to be passed through to Distribution Network Users during the review period less any capital expenditure that is included in a negative pass through amount that is required to be passed through to Distribution Network Users during the review period. 
(d)	The margin requirement is satisfied where the amount of the capital expenditure as a result of which the previous value of the regulatory asset base would otherwise be increased in accordance with clause S6.2.1(e) includes capital expenditure that represents a margin paid by the Distribution Network Service Provider in circumstances where the margin is referable to arrangements that, in the opinion of the AER, do not reflect arm's length terms.
(e)	The capitalisation requirement is satisfied where the amount of the capital expenditure as a result of which the previous value of the regulatory asset base would otherwise be increased in accordance with clause S6.2.1(e) includes expenditure that, under the Distribution Network Service Provider's applicable capitalisation policy submitted to the AER as part of a regulatory proposal, should have been treated as operating expenditure.
(f)	Where the overspending requirement is satisfied, and subject to paragraphs (g) and (h), the AER may determine that the amount of the capital expenditure as a result of which the previous value of the regulatory asset base would otherwise be increased in accordance with clause S6.2.1(e) should be reduced by such amount as the AER is satisfied corresponds to capital expenditure incurred during the review period that does not reasonably reflect the capital expenditure criteria.
(g)	The amount determined by the AER under paragraph (f):
(1)	must not be greater than the amount calculated in accordance with paragraph (c);
(2)	must be determined in a manner that is consistent with the capital expenditure incentive objective; and
(3)	must be determined taking into account the Capital Expenditure Incentive Guidelines.
(h)	In making a determination under paragraph (f), the AER must:
(1)	have regard to the capital expenditure factors; and
(2)	only take into account information and analysis that the Distribution Network Service Provider could reasonably be expected to have considered or undertaken at the time that it undertook the relevant capital expenditure.
(i)	Where the margin requirement is satisfied, and subject to paragraph (k), the AER may determine that the amount of the capital expenditure as a result of which the previous value of the regulatory asset base would otherwise be increased in accordance with clause S6.2.1(e) should be reduced by such of the margin referred to in paragraph (d) as the AER is reasonably satisfied would not have been paid if the arrangements to which the margin is referable had been on arm's length terms.
(j)	Where the capitalisation requirement is satisfied, and subject to paragraph (k), the AER may determine that the amount of the capital expenditure as a result of which the previous value of the regulatory asset base would otherwise be increased in accordance with clause S6.2.1(e) should be reduced by any or all of the amount of expenditure referred to in paragraph (e) which should have been treated as operating expenditure .
(k)	A determination made under paragraph (i) or (j) must be consistent with the capital expenditure incentive objective and, in making such a determination, the AER must take into account the Capital Expenditure Incentive Guidelines.
(l)	Nothing in this clause S6.2.2A is to be taken to preclude the AER from:
(1)	requiring a Distribution Network Service Provider to provide such information; or 
(2)	undertaking such analysis, 
as the AER considers appropriate to enable it to make a statement, with supporting reasons, as referred to in clause 6.12.2(b).
S6.2.2B	Depreciation
(a)	Pursuant to clause 6.12.1(18), the AER must decide, for a distribution determination, whether depreciation for establishing the regulatory asset base for a distribution system as at the commencement of the following regulatory control period is to be based on actual or forecast capital expenditure.
(b)	The decision referred to in paragraph (a) must be consistent with the capital expenditure incentive objective.
(c)	In making the decision referred to in paragraph (a), the AER must have regard to:
(1)	the incentives that the Distribution Network Service Provider has in relation to undertaking efficient capital expenditure, including as a result of the application of any incentive scheme or any other incentives under the Rules;
(2)	the substitution possibilities between assets with relatively short economic lives and assets with relatively long economic lives and the relative benefits of such asset types;
(3)	the extent to which any capital expenditure incurred by the Distribution Network Service Provider has exceeded the corresponding amount of forecast capital expenditure accepted or substituted by the AER and the amount of that excess expenditure which is not efficient;
(4)	the Capital Expenditure Incentive Guidelines; and
(5)	the capital expenditure factors.
S6.2.3	Roll forward of regulatory asset base within the same regulatory control period
(a)	Application of this clause
This clause applies to the establishment of the value of the regulatory asset base for a distribution system as at the beginning of one regulatory year in a regulatory control period on the roll forward of the regulatory asset base to that regulatory year from the immediately preceding regulatory year (if any) in that regulatory control period.
(b)	Roll forward model to comply with this clause
The roll forward model referred to in clause 6.5.1 must provide for that value to be established in accordance with the requirements of this clause.
(c)	Method of adjustment of value of regulatory asset base
The value of the regulatory asset base for a distribution system as at the beginning of the second or a subsequent year (the later year) in a regulatory control period must be calculated by adjusting the value (the previous value) of the regulatory asset base for that distribution system as at the beginning of the immediately preceding regulatory year (the previous year) in that regulatory control period as follows:
(1)	The previous value of the regulatory asset base must be increased by the amount of forecast capital expenditure accepted or substituted by the AER for the previous year in accordance with clause 6.5.7(c) or clause 6.12.1(3) (as the case may be).
(2)	The previous value of the regulatory asset base must be reduced by the amount of depreciation included in the Distribution Network Service Provider's annual revenue requirement for the previous year.
(3)	The previous value of the regulatory asset base must be reduced by the disposal value of any asset included in that value where the asset is forecast to be disposed of during the previous year.
(4)	The previous value of the regulatory asset base must be increased by an amount necessary to maintain the real value of the regulatory asset base as at the beginning of the later year by adjusting that value for inflation.
(d)	Allowance for working capital
If the AER determines that it is appropriate to do so, it may include an allowance for working capital in the regulatory asset base for a distribution system which is rolled forward in accordance with this clause.
