Origin Energy has approved the construction of a large-scale battery at the Mortlake Power Station in Victoria, with an investment of around $400 million.

The Mortlake Power Station battery, with a 300 MW capacity, is set to deliver up to 650 MWh of power, ensuring a reliable power supply for customers.

Origin CEO Frank Calabria said the Mortlake battery is a significant step towards the company’s goal of leading the energy transition through cleaner energy and customer solutions.

“I am pleased to announce that contracts have been signed with global energy storage systems supplier Fluence and site preparation and civil works are expected to commence over coming months,” Calabria stated.

“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. Today’s announcement follows our decision last year to approve Origin’s first large-scale battery at Eraring, which is currently under construction,” he added.

According to him, the Mortlake battery, a key component of Victoria’s South West Renewable Energy Zone, is expected to maintain grid stability and facilitate the integration of more renewable energy sources in the market.

Mortlake Power Station is Victoria’s largest gas-fired power station, having a generating capacity of 566 MW. The peaking power station uses gas from the Otway Basin.

The battery is anticipated to be commissioned in late 2026.
