The race for Australia’s largest big battery is heating up, with Origin Energy unveiling plans for a massive 700MW big battery to be located at the company’s Eraring power station in the New South Wales Hunter region.

Origin Energy’s plans for the big battery would include up to four hours of dispatchable power, providing up to 2,400MWh of energy storage capacity, and is currently the largest battery storage system under consideration in Australia.

The Eraring power station is expected to close by 2032, but remained open to the prospect that the power station could close earlier. The construction of a big battery project at the Eraring site would allow the battery to utilise the existing network connections and infrastructure, long after the power station has been decommissioned.

Origin Energy announced that it had issued an ‘expression of interest’ for potential suppliers and builders of the big battery to come forward, as well as kick-starting negotiations with network company TransGrid to connect the battery to the Eraring substation.

Origin Energy executive general manager for energy supply and operations, Greg Jarvis, said that the company understood it had a role to play in supporting the New South Wales energy system manage the entry of new wind and solar projects as the state’s coal plants exit the market. “The deployment of this battery at Eraring will support Origin’s orderly transition away from coal-fired generation by 2032, while complementing the policy objectives of the NSW energy roadmap,” Jarvis added.

Origin said that it expects that the battery would be installed in three stages, with the first stage of the project expected to be operational by late 2022.
