Market Review: Open
The AEMC is undertaking a review into the regulatory arrangements frameworks for stand-alone power systems under the National Electricity Law (NEL), the National Energy Retail Law (NERL) and associated rules.
A stand-alone power system (SAPS) is an electricity supply arrangement that is not physically connected to the national grid. The term encompasses both microgrids, which supply electricity to multiple customers, and individual power systems, which supply electricity to a single customer.
This review, requested by the COAG Energy Council, is looking at the law and rule changes required to allow local distribution network service providers to use SAPS where it is economically efficient to do so, while maintaining appropriate consumer protections and service standards. The review is also considering regulatory arrangements for SAPS that are provided by parties other than local DNSPs.
The terms of reference for the review sets out two priority areas of work:
- Priority 1 was to develop a national framework to facilitate the transition of grid-connected customers to SAPS supply provided by the current distribution network service provider (DNSP), as well as a mechanism for the transition of grid-connected customers to third party SAPS supply.
- Priority 2 is to develop a national framework for the ongoing regulation of third-party SAPS (that is, those not provided by the local distribution business).
Priority 2: Regulation of third party SAPS
On 27 June 2019 the AEMC published a draft report on priority 2 of the review.
The draft report sets out the Commission’s initial views on a regulatory framework that would require community groups, local councils, developers and other third party providers of stand-alone power systems to comply with jurisdictional regulations on reliability, safety and consumer protections, based on nationally agreed principles. Currently, if customers obtain their own supply using a stand-alone power system, those systems are subject to jurisdictional legislative frameworks that vary in their comprehensiveness.
The AEMC is recommending a tiered framework to allow for appropriate consumer protections to be provided in a proportionate manner while avoiding unnecessary costs, rather than a one-size-fits-all approach.
A consultation paper for priority 2 was published on 1 March 2019. The AEMC received 21 stakeholder submissions to the consultation paper which can be found below.
Next steps for priority 2
The Commission invites submissions on the draft report by 8 August 2019. A final report is due by the end of October 2019.
Priority 1: Enabling distribution businesses to provide SAPS
On 30 May 2019 the AEMC published a final report for priority 1. This report recommended a suite of changes to energy laws and rules to enable the use of stand-alone power systems by distributors. The reforms will help unlock the benefits of new technologies that are increasingly allowing electricity services to be delivered through alternatives to a traditional grid connection at a lower cost and with improved reliability, and with other benefits such as reduced bushfire risks.
Under the reforms, customers who receive stand-alone systems will retain all of their existing consumer protections, including access to retail competition and existing reliability and safety standards. As such, customers would not be disadvantaged where a distributor determined that it would be more efficient to supply them on a stand-alone basis. Cost savings arising from the use of lower cost stand-alone systems will flow through to all users of the distribution network, through lower network prices.
An issues paper for priority 1 was published on 11 September 2018, and a draft report for priority 1 was published on 18 December 2018.
Next steps for priority 1
The COAG Energy Council, AER, AEMO, state and territory governments and regulators all have a role to play in delivering the recommended changes. The AEMC has provided detailed information on how to change national energy laws and state-based regulations, and we will start work on changes to the rules as soon as the proposals are agreed by energy ministers.
The Commission concurrently worked on updates to the regulatory framework for embedded networks, with the two workstreams considering a number of related issues, particularly with regards to consumer protections.
The COAG Energy Council’s Energy Market Transformation work program, managed by the Energy Market Transformation Project Team (EMTPT), is considering the regulatory response to the emergence of SAPS as a viable option for providing electricity services to customers.
In general, SAPS are currently not captured under the national electricity frameworks. SAPS are subject to jurisdictional legislative frameworks that vary in their comprehensiveness. Queensland is currently the only state that applies the NERL retail protections to all off-grid electricity supply, and also applies the NERL distributor obligations to the 33 isolated systems run by Ergon Energy.
While SAPS may provide benefits, regulation of these systems is justified for many of the same reasons as for standard supply from the national grid. Consequently there is now a need for more robust regulatory arrangements to be developed for SAPS.View less
