Firming Infrastructure

We have announced the results of firming infrastructure tender in NSW, a significant contribution to the reliability and security of our energy system. AEMO Services, acting as the NSW Consumer Trustee conducted this tender in response to a direction by the NSW Minister for Energy.

The tender originally sought at least 380 MW of firming infrastructure and demand response from the market but was expanded to 930 MW with the Commonwealth Government supporting up to an additional 550MW of firming infrastructure through the Capacity Investment Scheme (CIS).

The successful projects in Tender Round 2 include two, 2-hour duration Battery Energy Storage Systems (BESS) projects, one 4-hour duration BESS project, and three demand response projects. Combined, they will provide 1,075 MW with almost 3 gigawatt hours (GWh) of energy to the network.

Project name	Proponent	Technology	Capacity	Storage capacity
Liddell BESS	AGL Energy	Lithium-ion batter	500 MW	1,000 MWh
Orana BESS	Akaysha Energy	Lithium-ion batter	415 MW	1,660 MWh
Smithfield BESS	Iberdrola Energy	Lithium-ion batter	65 MW	130 MWh
Virtual Power Plant (VPP)	Enel X Australia	Demand Response	95 MW comprising three separate VPPs (50MW, 20 MW, and 25 MW)	Minimum dispatch duration of 2 hours, which will be maintained throughout the LTESA term.

All projects committed to be operational by December 2025 and make meaningful contributions to the local workforce and communities. For more information on the successful projects, please see our Market Briefing Note.
