Australia’s Origin Energy has confirmed that it is to build a 300MW / 650MWh battery at the Mortlake Power Station in south-west Victoria at a cost of A$400 million.
The battery is expected to be commissioned late in 2026.
Origin will begin site preparation and civil works in the “coming months” after signing contracts with energy storage systems supplier Fluence.
Origin CEO Frank Calabria said, “The Mortlake battery is another significant step in our ambition to lead the energy transition through cleaner energy and customer solutions.
“Origin’s strategy is to accelerate renewable energy and storage in our portfolio and we expect large-scale batteries and other storage technologies to play a vital role in Australia’s energy transition. With the proliferation of wind and solar farms, particularly in Victoria’s South West Renewable Energy Zone, the Mortlake battery will help keep the grid stable and support more renewable energy coming into the system as the market continues to decarbonise.”
