Post 2025 National Electricity Market Design
The COAG Energy Council has requested that the Energy Security Board (ESB) consider whether any changes are required to the core National Electricity Market framework in order to facilitate the technological shift towards a lower emissions electricity system. It is intended such changes will deal with increasing concentrations of distributed energy resources at least cost and without impacting reliability of supply.
The COAG Energy Council has approved ESB's forward work plan, which lists indicative timeframes within which stages of their advice will be developed in the lead up to its implementation in 2025.
December 2018 – ESB's forward work plan approved by the COAG Energy Council
22 March 2019 – COAG Energy Council officially tasked ESB to develop a market framework in place of or amending the existing market design to ensure a higher degree of network reliability
March-August 2019 – Assessment of international options for a more secure, reliable and lower emissions electricity system.
2 September 2019 – Stakeholder consultation regarding the future scenarios that will be used by ESB when assessing options for change, the assessment framework used when evaluating market design options and the opportunities, challenges and implications of proposed market design options.
To be completed:
December 2019 – Identification of two potential options (in addition to current market design) to deliver a secure, reliable, lower emissions electricity system at least cost.
Stakeholder consultation commences on these two options.
2020 – Develop detailed design and analysis of two potential options and provide recommendations regarding suggested amended or alternative market designs
2021 – Develop, consult and agree any changes to the National Electricity Law and/or Rules required to implement amended or alternative market design
1 July 2022 – Finalisation of changes to post-2025 Market Design
