Wärtsilä & Origin sign €300m Australian storage deal

April 20, 2023

Technology group Wärtsilä has been selected by Origin Energy as the preferred contractor to deliver the  460MW / 920MWh first phase of what it says will be “one of Australia’s largest energy storage projects”. 

The Eraring battery will be installed at Origin’s Eraring Power Station, with the potential for it to be expanded to 700 MW / 2,800 MWh in the future. 

The companies have signed an engineered equipment delivery (EEQ) contract with a total value of slightly more than €300 million, Wärtsilä’s “largest single energy storage deal to-date”. Equipment delivery is expected to occur from October 2023 to September 2024.

The Eraring battery will be connected to Australia’s National Electricity Market (NEM) and “support energy security and reliability” in the state of New South Wales, a statement said.
