Final report published on Reliability Panel's review of the guidelines for identifying reviewable operating incidents

20 December 2012

On 20 December 2012 the Reliability Panel published the final report and the final revised guidelines for identifying reviewable operating incidents. 

Consistent with the requirements under the National Electricity Rules (NER), the final guidelines focus on reviewing incidents that could have a significant impact on the operation of the power system.  To this end, the final guidelines introduce the concept of ‘critical transmission elements’.  Incidents that impact critical transmission elements will need to be reviewed by AEMO.  The revised guidelines come into effect on 1 April 2013.  This provides time for AEMO to consult with stakeholders on the definition of critical transmission elements.

 

Looking ahead to lower cost ways to support electric vehicles

11 December 2012

The AEMC today released its final advice on implications for energy market arrangements from the introduction of electric and natural gas powered vehicles.

The Commission has taken a long term view in relation to the introduction of market reforms designed to support the economically efficient uptake of electric and natural gas vehicles. Electric vehicles in particular are another new “appliance” which is set to place new demands on Australia’s power system. This review has found that each electric vehicle could impose additional network and generation costs from $7500 up to $10,000 per vehicle over the 5 years from 2015 to 2020 in the absence of appropriate pricing signals and efficient charging decisions.

AEMC Chairman, John Pierce, said today that each electric vehicle could result in additional generation and network costs that, under current market arrangements would be shared by all consumers.

“Promotion of efficient investment by both consumers and service providers in electric vehicles requires some changes to electricity market arrangements,” Mr Pierce said.

 “To facilitate efficient market outcomes in relation to electric vehicles we recommend that pricing signals (particularly network pricing signals) should reflect the underlying cost of supplying electricity.

The final advice confirms the review’s findings that efficient electric vehicle charging and consumer choice would be promoted by development of new metering arrangements in the market.

AEMC recommendations include:

  • As stated in our Power of choice review, we propose that cost reflective network pricing be phased in through a banding approach, with medium to large consumers transitioned to efficient and flexible network prices. This should be set to capture a high proportion of EV consumers.
  • Introducing new metering arrangements that enable consumers to separate their electric vehicle power consumption from their household consumption. This would enable them to source the most appropriate mixture of retail deals to best reflect their preferences;
  • Adoption of metering with interval reading capability for all electric vehicles;
  • Devising new metering arrangements that enable third parties to install electric vehicle charging infrastructure in commercial properties (eg. shopping centres and business parks); and
  • Specifying principles for load management where an electric vehicle owner delegates charging rights to another party.

The final advice concludes that no significant changes need to be made to market arrangements to cater for the uptake of natural gas vehicles.

Last resort planning power 2012 review

11 December 2012

The Australian Energy Market Commission (AEMC) today released the final report for its Last Resort Planning Power 2012 Review in relation to the National Electricity Market (NEM).

The National Electricity Rules contain a requirement for the AEMC to report annually on whether transmission network service provider planning had responded to inter-regional network congestion as identified in national planning documents. The 2012 review finds that interconnector capacity received an appropriate level of assessment and there was no need for the AEMC to exercise its last resort planning power in the year under review.

The NEM comprises five regions with interconnected transmission networks. The flow of electricity between regions is critical for the efficient and reliable operation of the market as a whole. Investment in interconnectors and the regional networks that support them has the potential to ensure reliable supply for customers in the most cost efficient way, as well as allowing improved market efficiency through cross regional trading.

Each region of the NEM has its own transmission Jurisdictional Planning Body (JPB). Each JPB is responsible for undertaking transmission infrastructure forward planning within its region. In addition, the Australian Energy Market Operator (AEMO) as the National Transmission Planner (NTP) develops a strategic overview of the future transmission requirements of the NEM.

The National Electricity Rules (NER) allocate the Last Resort Planning Power (LRPP) to the Australian Energy Market Commission (AEMC). This is the power to direct a Registered Participant to undertake a Regulatory Investment Test for Transmission (RIT-T) to determine if a transmission project is warranted. The AEMC is to exercise this power if it considers that the JPBs are not giving due regard to a constraint on inter-regional flows. Each year the AEMC considers the documented planning actions of the JPBs and the NTP and reports on its reasons for either issuing a direction or not doing so. The AEMC is yet to exercise its power to issue a direction.

On December 6 the AEMC published the second draft determination and second draft rule in relation to the inter-regional transmission charge rule change request.

AEMC proposes new opportunities for consumers to manage their electricity use and expenditure

30 November 2012

Substantial reforms to the National Electricity Market (NEM) have been recommended to Commonwealth and state governments by the Australian Energy Market Commission (AEMC) in its final report of the Power of Choice Review – giving consumers options in the way they use electricity.

The recommendations include changes to the National Electricity Rules (NER), the National Energy Retail Rules and several government programs to provide the information, technology and price options, which households, business and industry can use to manage their electricity use and expenditure.

Residential consumers may make savings, in the short term, if they choose to change their retail price offers and adapt consumption patterns.

The 18 month review today released recommendations and a proposed implementation plan to give consumers real choice about how they use electricity and what they pay.

AEMC Chairman, Mr John Pierce, said the package of reforms would enable the electricity market to meet the needs of consumers over the next 15-20 years.

“The reforms provide more opportunities for consumers to make informed choices based on the benefits that end use services provide. Ultimately, consumers are in the best position to decide what works for them.

The overall benefits to the system will be realised through the choices that consumers make.” Mr Pierce said.

AEMC recommendations propose:

–        More flexible electricity pricing to better reflect the costs of electricity supply at different times.

–        Price incentives for consumers who choose to change their consumption patterns, with safeguards for consumers with limited capacity to change their consumption.

–        A review of existing arrangements to make it easier for consumers to switch between electricity retailers.

–        Encouraging commercial investment in the technology that enables flexible pricing options and other demand side participation products.

–        Rewarding commercial and industrial energy users for changing their consumption patterns.

–        Improving consumer access to electricity consumption data to enhance understanding of their energy use.

–        Clarifying the role of third parties providing energy management services to improve competition and robust consumer protection.

–        Incentives for networks to consider demand side projects in lieu of infrastructure investments.

–        Allowing consumers to sell energy they generate (eg. solar, embedded generation, battery storage) to parties other than their retail electricity supplier.

A comprehensive awareness program to help consumers to make informed decisions about their electricity consumption is recommended prior to the implementation of pricing and metering reforms.

The Power of choice review is a combined State, Territory and Commonwealth government initiative through the Standing Council on Energy and Resources (SCER). The final report, together with a detailed implementation plan, is with SCER ministers for consideration.

Mr Pierce said most recommendations could be implemented with changes to the rules governing energy market regulation; others require decisions or legislative change by the relevant governments.

Reports on time taken to finalise network regulation rule changes

29 November 2012

The AEMC today published reports providing reasons why the network regulation rule changes were not finalised within 12 months from their formal commencement. These reports are required under section 108A of the National Electricity Law and section 320 of the National Gas Law.

 

Final determination made on Small Generation Aggregator Framework

29 November 2012

On 29 November 2012, the AEMC published the Small Generation Aggregator Framework final determination and final rule. The rule as made seeks to lessen potential barriers to fully participating in the market faced by small generators.

The rule was proposed by the Australian Energy Market Operator (AEMO).  AEMO considered that, for generators that would otherwise be exempt from registration requirements, the process of becoming a Market Generator to sell output at the spot price represented an inefficient cost. To address this AEMO proposed that small generating units be able to aggregate and sell their generation through a third party.

The rule as made is the proposed rule with consequential alterations. A new category of Market Participant has been added to the National Electricity Rules (NER). This Market Small Generation Aggregator (MSGA) will be able to receive the spot price on behalf of a portfolio of generators that are exempt from the requirement to register with AEMO due to their small size. This addition of this category of participant will provide more options to the owners of small generating units, potentially leading to a more efficient wholesale market.

Final determination made on network regulation rule changes

29 November 2012

The AEMC today published its final determination and final rules on the regulation of electricity and gas network prices.

The AEMC’s final position published on 15 November 2012 has been confirmed. Implementation arrangements have now been included in the rules to set out how they will apply to specific businesses.

In short, the new rules give the regulator additional tools to set maximum prices which network businesses can charge. The rules improve the strength and capacity of the regulator to determine network price increases so consumers don’t pay more than necessary for reliable supplies of electricity and gas.

The new rules take effect immediately. They will be applied by the regulators, subject to the implementation arrangements, the next time the regulator makes a determination for a particular business.

AEMC Chairman, John Pierce, said the new rules were focused on improving the AER’s capacity by giving it an enhanced toolkit to determine efficient costs for each regulated business – and enabling it to decide what costs are efficient.

“These new rules will enhance the AER’s ability to set efficient costs,” Mr Pierce said.

“In line with the timetable for price and revenue determinations, the new rules will be applied starting with the New South Wales businesses in 2013. This means that from 1 July 2014 the new rules will start to have an impact.”

In addition to these rule changes, the AEMC is working across the electricity and gas supply chains to identify other areas where changes can be made to improve the efficiency of the total system. This work includes looking at ways for consumers to have more control over the way they use electricity and the prices they pay through our Power of Choice review. The Transmission Frameworks Review is looking at ways to reduce long-term price pressures. The Reliability Standards Review has suggested there is merit of moving to a national framework for distribution reliability standards. Advice on all of these areas is being provided to governments.

Draft report published on Review of Arrangements for Compensation following an Administered Price, Market Price Cap or Market Floor Price

29 November 2012

The AEMC today published a draft report for the review of compensation arrangements following an administered price, market price cap or market floor price.

The frameworks which set out these compensation provisions are included in the national electricity rules.  Claims for compensation are unusual events; to date, only one claim has been made in the NEM. However, it is important that the compensation frameworks are transparent and effective, as this will help ensure efficient outcomes for consumers.

The draft report contains several key recommendations designed to improve the functioning of the compensation frameworks. These include:

  • new processes for determining who is eligible to claim compensation;
  • changes to the AEMC’s process for assessing compensation claims;
  • clarification of the purpose of compensation; and
  • clarification of the processes for recovering the cost of compensation from market customers.

Stakeholders are invited to provide comment on the draft report. Submissions must be received no later than 24 January 2013.

Draft determination made on Changes to normal voltage

29 November 2012

On 29 November 2012, the AEMC published a draft rule determination and draft rule in response to a rule change proposal from International Power GDF Suez regarding transparency around requests to change the normal voltage level.

The Commission has determined to make a more preferable draft rule which requires the Australian Energy Market Operator (AEMO) to notify registered participants of a request to change the normal voltage level. The draft rule also requires AEMO to notify registered participants of the outcome of such a request. The AEMC considers that the draft rule would improve market transparency and efficiency by assisting registered participants to make more informed investment and operational decisions.
