AGL Energy and Enel X Australia secured Long-Term Energy Service Agreements (LTESAs) through the New South Wales (NSW) Roadmap Tender 7 for Firming Infrastructure, committing to deliver 532 MW or 2,218 MWh of firming capacity by the end of November 2027. The 2 GWh Tomago battery energy storage system (BESS), a 500 MW / 2,000 MWh lithium-ion project developed by AGL in the Hunter region near Raymond Terrace, will support the Hunter-Central Coast Renewable Energy Zone (REZ). Enel X Australia’s 32 MW demand response virtual power plant (VPP) will aggregate flexible demand across businesses in Greater Sydney, the Central Coast, Newcastle, and the Lower Hunter to enhance grid reliability during peak demand and system stress. The projects are contracted to support the grid during Lack of Reserve (LOR) events, with performance obligations requiring capacity availability during LOR 2 and 3 events. The Tomago BESS, valued at approximately $800 million (USD 572 million), is expected to commence operations by November 2027, while the VPP will begin commercial operations by 1 July 2027.
