Anza Power has signed a tolling agreement with Amazon Australia for the 50MW/200MWh Bairnsdale battery energy storage system (BESS) in East Gippsland, Victoria. The deal marks Amazon's first standalone battery storage tolling agreement in the Asia-Pacific region and is described as a first-of-its-kind agreement in Australia for a non-energy business to contract for a standalone battery storage system.
Anza Power is a renewable energy developer, owner, and operator launched by global infrastructure investor I Squared Capital in January 2026, with a US$300 million commitment to deliver reliable, clean energy across Australia and New Zealand. Unlike the solar-plus-storage projects that have typically anchored Amazon's Australian renewable energy portfolio, the Bairnsdale system will connect directly to the electricity grid as an independent asset, without being paired with a co-located solar or wind farm.
The Bairnsdale deal extends a pattern of escalating battery storage commitments Amazon has made in Australia over the past year. In April 2026, Amazon signed nine renewable energy power purchase agreements totalling 430MW, eight of which included co-located battery storage. In July 2026, the company signed a battery storage PPA covering the 100MW/220MWh storage component of European Energy's Winton North solar-plus-storage project. According to Amazon, the company has now invested in ten battery storage projects across Australia, seven of them in Victoria, with a combined capacity of 368MW once completed.
What remains unknown is the financial value or duration of the Bairnsdale tolling agreement, as the source does not disclose those terms. The project is designed to store electricity and dispatch it during periods of peak demand, supporting regional grid reliability and enabling greater integration of renewable energy generation into the National Electricity Market, but specific operational timelines and commissioning dates were not provided in the available reporting.
