US tech giant Amazon has secured a landmark tolling agreement with Anza Power, the Australian subsidiary of US infrastructure investment firm I Squared Capital, for the 50 MW/200 MWh Bairnsdale battery energy storage system (BESS) under development in Victoria, marking a global first for Amazon in standalone battery storage asset cooperation.

Under the unprecedented deal, Amazon gains full access to the energy stored in the Bairnsdale BESS, along with exclusive rights to control the facility’s charging and discharging operations and conduct grid arbitrage activities. In exchange, Amazon will pay a fixed regular fee to Sydney-based Anza Power, eliminating the need for the company to undertake any construction or maintenance responsibilities for the battery storage project. Notably, the partnership also sets a new benchmark in Australia, being the nation’s first-ever BESS tolling agreement inked by a non-energy corporate entity.

Unlike conventional wind or solar-linked storage facilities, the Bairnsdale BESS will operate as an independent grid asset with direct connection to Australia’s electricity network, delivering dedicated, standalone energy storage capacity. Prior to this deal, Australia’s BESS tolling partnerships were exclusively limited to energy sector players, including local gentailers and developers such as EnergyAustralia and Akaysha Energy, which holds a 12-year virtual tolling agreement for the Orana BESS project.

Carlo Frigerio, Chief Executive Officer of Anza Power, highlighted the deal’s industry significance amid the global shift toward low-carbon energy infrastructure. “This agreement underscores the surging demand from major corporate energy buyers for tailored dedicated storage solutions that underpin a stable, low-emission electricity grid,” Frigerio stated. “The Bairnsdale project showcases our capability to deliver flexible energy infrastructure that adapts to evolving market and customer requirements. We will continue to build on the strong momentum we have gained since Anza’s launch earlier this year.”
