The e-commerce giant on Thursday announced it had signed nine more renewable energy purchase agreements, taking its total investment to 20 projects with a combined capacity of 990 megawatts once operational.
Amazon said it had invested an estimated $2.8 billion into renewable energy in Australia since 2020, and was the largest corporate purchaser of carbon-free energy in 2025.
The agreements come as the company begins spending $20 billion on data centres in Sydney and Melbourne to support customer demand for cloud computing and artificial intelligence, in a deal announced in 2025 alongside Prime Minister Anthony Albanese at its Seattle headquarters.
Matt O'Rourke, head of infrastructure and energy policy at Amazon Web Services, said the green energy projects would not directly power Amazon's data centres but provide power to the national grid that those centres draw electricity from.
"The motivation stems from our commitment to achieving net zero carbon by 2040, and that's really our North Star," he told AAP.Â
"Everything we're doing works back from that, and our involvement in renewable energy is part of that."
The deals lock in an offtake price for power over 15 years, helping the green energy developers de-risk their projects and bring them to fruition.
The projects announced Thursday include an agreement to purchase power from stage two of the Golden Plains 2 wind farm in Rokewood, Victoria, which will become the southern hemisphere's largest wind farm when it completes in mid-2027.
Amazon Australia has also agreed to buy power from three utility-scale solar and battery hybrids, four distributed solar-battery projects, and a new battery storage project at the Mokoan solar farm under construction in Winton, Victoria.
The battery storage deals are a first for Amazon outside of the United States.
