(b)	The structure of Participant fees must, to the extent practicable, be consistent with the following principles:
(1)	the structure of Participant fees should be simple;
(2)	Participant fees should recover the budgeted revenue requirements for AEMO determined under clause 2.11.3 on a basis where:
(i)	the following principles are relevant to the recovery of recurrent expenditure:
(A)	if AEMO recovers an excess of revenue over expenditure from the provision of a particular service in a financial year, it may roll over the excess to a later financial year (or later financial years) so as to reduce revenue requirements in the later financial year (or years);
(B)	AEMO may recover a shortfall of revenue as against expenditure for the provision of a particular service in a later financial year or later financial years;
(C)	AEMO may take any other action it considers desirable to smooth the impact of actual or anticipated cost variations on the users of a service provided by AEMO;
(ii)	capital expenditures (incurred after market commencement) are recovered through the depreciation or amortisation of the assets acquired by the capital expenditure in a manner that is consistent with generally accepted accounting principles;
(iii)	costs of transition are recovered over a period of 4 years from the changeover date.
(iv)	notwithstanding clauses 2.11.1(b)(2)(i), (ii) and (iii), expenditure incurred by, and depreciation and amortisation charged to, AEMO associated with a declared NEM project are recovered from the start date and over the period determined for that declared NEM project under clauses 2.11.1(bb) or 2.11.1(bd). Amounts associated with a declared NEM project determined in accordance with this clause are to be recovered through an additional Participant fee determined in accordance with clauses 2.11.1(bb) or 2.11.1(bd) until the next general determination of all Participant fees is made under clause 2.11.1(a);
(3)	the components of Participant fees charged to each Registered Participant should be reflective of the extent to which the budgeted revenue requirements for AEMO involve that Registered Participant;
(4)	Participant fees should not unreasonably discriminate against a category or categories of Registered Participants; and
(5)	the fixed component of Participant fees for a Market Ancillary Services Provider who is registered with AEMO solely for the purpose of providing market ancillary services, may be zero.
(ba)	AEMO may determine any of the following projects to be a declared NEM project:
(1)	a major reform or development (including an anticipated reform or development) of the market; or
(2)	a major change (including an anticipated change) to a function, responsibility, obligation or power of AEMO under the Rules; or
(3)	a major change (including an anticipated change) to any of the computer software or systems that AEMO uses in the performance of any of its functions, responsibilities, obligations or powers under the Rules.
(bb)	When AEMO determines a project to be a declared NEM project under clause 2.11.1(ba), it must also determine the start date for recovery and the period or periods over which recovery will occur for the declared NEM project. AEMO must also determine the structure of an additional Participant fee to be used in the recovery of costs associated with a declared NEM project until the next general determination of all Participant fees is made under clause 2.11.1(a).
(bc)	In making determinations under clauses 2.11.1(ba) and (bb), AEMO must comply with the Rules consultation procedures.
(bd)	The introduction and facilitation of full retail competition is taken to have been determined to be a declared NEM project under clause 2.11.1(ba) and AEMO will be entitled to recover through Participant fees expenditure incurred by, and depreciation and amortisation charged to, AEMO in respect of full retail competition. The period or periods over which recovery will occur for this declared NEM project will be determined by AEMO using the Rules consultation procedures. If any amounts associated with the introduction and facilitation of full retail competition are to be recovered prior to the next general determination of all Participant fees under clause 2.11.1(a), such recovery must be through an additional Participant fee determined using the Rules consultation procedures.
(c)	The components of the Participant fees may include, but are not limited to:
(1)	registration fees, comprising an annual fee payable by each person for each Registered Participant category in which they are registered;
(2)	ancillary service fees, to recover AEMO's budgeted revenue requirements in relation to its procurement of non-market ancillary services;
(3)	power system operations fees, to recover AEMO's budgeted revenue requirements in relation to its power system operation activities described in clause 2.11.3(b)(2);
(4)	metering fees to recover AEMO's budgeted revenue requirements for the collection, storage and processing of metering data;
(5)	billing and settlements fees, to recover AEMO's budgeted revenue requirements as described in clause 2.11.3(b)(4); and
(5A)	NTP function fees to recover AEMO's budgeted revenue requirement as described in clause 2.11.3(b)(4A);
(5B)	additional advisory function fees to recover AEMO's budgeted revenue requirement as described in clause 2.11.3(b)(4B);
(6)	administration fees, to recover the remainder of AEMO's budgeted revenue requirements;
and each component of the Participant fees may take into account adjustments which may be appropriate in light of the matters described in clauses 2.11.3(b)(7) or (8).
(d)	In undertaking the process described in clause 2.11.1(a) AEMO must consider other fee structures in existence which it thinks appropriate for comparison purposes.
(e)	AEMO must publish to Registered Participants and to such other persons as AEMO thinks appropriate, the structure of Participant fees determined, the methods used in determining the structure and an assessment of the extent to which the structure complies with the principles set out in clause 2.11.1(b) at least 3 months prior to the implementation of the structure.
2.11.2	Payment of Participant fees
(a)	AEMO may charge a Registered Participant the relevant components of Participant fees in accordance with the structure of Participant fees by giving the Registered Participant a statement setting out the amount payable by that Registered Participant and the date for payment.
(b)	In the case of a Market Participant, AEMO may, alternatively, include the relevant amount in the statements described in clause 3.15.15.
(c)	A Registered Participant must pay to AEMO the net amount stated to be payable by that Registered Participant in a statement issued under clause 2.11.2(a) or in accordance with clause 2.11.2(b) to meet AEMO's budgeted revenue requirements by the date specified for payment, whether or not the Registered Participant disputes the net amount payable.
