Amazon Australia has signed nine renewable energy power purchase agreements in New South Wales and Victoria, adding 430MW to the National Electricity Market.
Once operational, the deals will lift Amazon's contracted renewable energy footprint in Australia to 990MW across 20 projects, according to the company.
The new portfolio spans generation and storage. It includes one wind farm, three utility-scale solar and battery hybrid projects, four distributed solar-battery projects, and a new battery installation at the Mokoan Solar Farm in Victoria.
Eight of the nine agreements include battery storage, marking Amazon's first solar-battery hybrid projects in Australia. Amazon also said the portfolio is its first of this kind outside the United States.
Between 2020 and 2025, Amazon invested an estimated AUD $2.8 billion in renewable energy projects in Australia, and said this latest round of agreements was its largest renewable energy investment in a single year in the country.
BloombergNEF ranked Amazon as the largest corporate purchaser of carbon-free energy in Australia for 2025, according to the company, which also said it is among the leading corporate purchasers worldwide.
Project mix
The largest project in the latest group is Golden Plains 2 in Victoria, a TagEnergy wind development with 201.8MW of renewable energy capacity. In New South Wales, OX2's Muswellbrook solar and battery project adds 94.5MW of solar capacity and 70MW of battery storage.
Forest Glen in New South Wales, developed by X-ELIO, contributes 72MW of solar generation and 72MW of battery storage. Laceby in Victoria, developed by Anza, adds 48MW of solar and 48MW of storage.
Amazon has also contracted four smaller distributed solar and battery projects with Anza. Stanbridge in New South Wales adds 3.8MW of solar and 3.8MW of storage, while Indigo, Barnawartha, and Mooroopna in Victoria add 3.6MW, 3.6MW, and 3.4MW respectively, each paired with matching battery storage. The Mokoan battery project in Victoria, developed by European Energy, adds 32MW of storage.
The agreements are intended to expand the supply of carbon-free electricity while supporting grid reliability, Amazon said. Battery storage has become central to Australia's electricity transition as more intermittent renewable generation comes online and market operators seek greater flexibility to manage supply and demand.
Land use
Some of the developments also reflect broader trends in renewable project siting. Amazon said the Muswellbrook solar farm is located on rehabilitated or brownfield land, including sites redeveloped from former coal mining areas.
Other projects incorporate agricultural co-use, including livestock grazing between solar panels. Such arrangements have become more common as developers and landowners look for ways to combine energy generation with continued farming activity.
The latest energy procurement comes alongside Amazon's broader infrastructure build-out in Australia, particularly in data centres. Large technology companies face growing scrutiny over how they will meet the rising electricity demand linked to cloud computing and artificial intelligence infrastructure.
That has made long-term power purchase agreements an increasingly important tool for securing supply and helping new renewable projects obtain finance. In Australia, battery-backed contracts are also being closely watched because they offer a way to pair new generation with dispatchable storage.
Matt O'Rourke, AWS head of infrastructure and energy policy for Australia and New Zealand at Amazon, said: "This is Amazon's largest single-year renewable energy investment in Australia and brings our total investment in renewable energy projects in Australia to AU$2.8 billion since 2020. We're proud to be helping accelerate the transition to a more sustainable energy future."
He also highlighted the link between energy supply and Amazon's computing operations. "As we expand our cloud and AI infrastructure, we're powering it not only with carbon-free energy, but also battery storage that strengthens grid reliability and proves data centres can run confidently on an increasingly renewables-based system," O'Rourke said.
He said the long-term structure of the contracts could also help projects move ahead. "These long-term, storage-backed PPAs enable new projects to proceed and help to stabilise electricity costs. These projects help accelerate Australia's clean energy transition and are part of Amazon's Climate Pledge goal to reach net-zero carbon across our operations by 2040," O'Rourke said.
