Origin has committed $80 million (USD 53.2 million) to construct the fourth stage of the project, which will lift the dispatch duration of stage two of the Eraring battery project to nearly six hours, allowing it to store electricity produced in the daytime such as from solar, for release when needed most.
Construction of stage four will begin before the end of the year and is anticipated to come online in the first quarter of the 2027 calendar year.
All other stages of the project are also progressing on track, delivering Origin additional storage and dispatch capability. Across all four stages, the total size of the Eraring battery will now be 700MW / 3,160MWh, providing 4.5 hours of storage on average.
Origin’s Head of Energy Supply and Operations, Greg Jarvis said, “This next stage of the Eraring big battery adds 360 MWh of storage, building on the work now underway and strengthening the site’s status as the largest approved battery energy storage system in the Southern Hemisphere.”
“As Australia continues its energy transition, large-scale batteries will be essential for reliable supply of energy, supporting more renewables coming online and helping ease pressure on wholesale prices.”
“Batteries can respond instantly to changes in supply and demand, which is why they’re becoming a core part of Australia’s renewable energy future.”
“We’re excited to add additional storage capacity at Eraring to cover the evening peak – the period of highest electricity demand – as we continue to transform the site to support the reliability and security of electricity supply through the energy transition.”
“When complete, Australia’s largest power station site will host the nation’s largest approved battery storage system, reinforcing Eraring’s role as critical infrastructure at the centre of Australia’s energy system for decades to come,” Mr Jarvis said.
Origin has committed to developing or contracting 1.7 GW in owned and tolled large-scale battery projects, including at Eraring, Mortlake Power Station in Victoria, the Summerfield battery storage project in South Australia and the Supernode battery in Queensland.
Battery equipment for stage four of the Eraring battery will be supplied by Finnish technology group Wärtsilä and design and construction services will be provided by Enerven, consistent with the rest of the project.
