Amazon has signed nine new wind, solar and battery storage power purchase agreements across New South Wales and Victoria, marking the global tech giant’s largest ever renewables investment in a single year and making it the largest corporate power purchaser in Australia this financial year.
Amazon Australia announced the huge 430 megawatt (MW), $A2.8 billion buy-up on Wednesday, with eight of the nine deals incorporating battery storage – and three of those projects being utility-scale solar-battery hybrids – a first for Amazon outside of the United States.
The newly signed portfolio includes a contract to buy just over 201 MW from Australia’s largest operational wind farm, Tag Energy’s Golden Plains project in Victoria, which with the powering up of a 577 MW second stage is making its way towards a total capacity of 1.33 gigawatts (GW).
The portfolio also includes a 32 MW offtake from a new battery that will be installed at the 46 MW Mokoan Solar Farm, an operational European Energy project in Winton, Victoria, with which Amazon has a previously signed PPA.
The three large-scale solar-hybrid PPAs include 94.5 MW of PV and 70 MW of battery capacity from OX2’s Muswellbrook project in New South Wales coal country, 72 MW each of PV and battery from X-ELIO’s Forest Glen project near Dubbo in NSW, and 48 MW each from Anza Power’s Laceby project near Wangaratta in Victoria.
Another 14.4 MW of firmed renewables is contracted across four distributed solar-BESS hybrids in Victoria and NSW, all owned by Anza Power, through PPAs sized between 3.4 MW and 3.8 MW.
All told, the new projects take Amazon’s total investment in Australia to 20 renewable energy projects, with a combined capacity of 990 MW once all of the projects are fully operational – enough to power the equivalent of more than half a million households a year (but far fewer data centres).
Even before this major new deal, Amazon had established itself as a major buyer of renewables power contracts in Australia. Between 2020 and 2025, it invested an estimated another $A2.8 billion in solar and wind projects across the country.
Amazon Web Services head of infrastrucrure and energy policy for Australia and New Zealand, Matt O’Rourke, says this latest round of buying has seen the web giant’s focus shift to projects with storage, mirroring the market’s current obsession with hybrid solar and batteries.
“In Australia, we’re entirely focused on renewables firmed with batteries,” O’Rourke tells Renew Economy. “That’s reflected in this set, but in particular with the Makoan bolt-on, where we’ve seen an opportunity to bolt a battery project onto an existing solar [project].”
O’Rourke says that the power hungry company is “generally, spoiled for choice” on solar and wind projects to contract power from in Australia, but that “there can always be more,” as the business of artificial intelligence (AI) and big data continues to boom.
Last June, Amazon announced a $A20 billion investment to expand data centre infrastructure in Sydney and Melbourne by 2029, supporting the increasing demand for cloud computing and AI, and enabling organisations of all sizes to modernise their 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,” he said in a separate statement.
“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 says that Amazon’s own net-zero target – which it aims to hit a decade earlier than Australia – is “really our North Star driving this and all of our sustainability initiatives throughout our business.” To this end, the company has zero interest in contracting fossil fuels of any kind.
As for the economics, Amazon is no different from the most companies in being notoriously cagey about revealing the financial terms of power offtake deals. But O’Rourke puts it this way: “The finances need to work out as well, [and] we are reaching PPAs with with the partners on agreed terms.”
“We are continuing to play our role as an off-taker to try and provide that revenue certainty to get projects over the line and bring them into the grid,” he adds.
“These nine PPAs have seen Amazon become the largest corporate purchaser of renewable energy in Australia in 2025, so we’re quite proud of that achievement and we want to double down and do more.”
