Google, AirTrunk and European Energy Australia Complete 25 MW Mulwala Solar Farm to Power Australian Digital Infrastructure

Google, AirTrunk and European Energy Australia have announced that the 25-megawatt Mulwala Solar Farm in the Riverina district of New South Wales is reaching completion and about to connect to the National Electricity Market, delivering on a corporate power purchase agreement announced in 2023. The project will inject new clean energy capacity into Australia's grid, supporting the country's broader energy transition while advancing Google's aim to operate on carbon-free energy around the clock. The Mulwala Solar Farm represents one of the first examples in Australia of digital infrastructure investment being directly linked to new-build renewable energy generation, creating a blueprint for how the technology sector can partner locally to bring additional clean capacity online.

 

The PPA Structure and Its Significance

 

The Mulwala Solar Farm operates under a corporate PPA structure that connects Google's data centre electricity demand directly to a newly constructed solar asset rather than relying on existing renewable capacity or certificate markets. This additionality dimension, bringing new generation into the grid rather than simply claiming credits from existing assets, is increasingly recognised as the more credible approach to corporate clean energy procurement by both investors and regulators assessing the genuine climate impact of technology company energy strategies. By partnering with AirTrunk as the data centre operator and European Energy Australia as the renewable energy developer, Google has structured a three-party collaboration that links the full value chain from solar generation through transmission to digital infrastructure consumption.

Bikash Koley, Vice President of Global Infrastructure at Google, said Australia has ambitious energy goals and that the company wants to ensure the growth of the digital economy directly accelerates the transition to a cleaner grid. He described Mulwala Solar Farm as an example of how AI and digital infrastructure can be built responsibly as part of Google's Digital Future Initiative in Australia, demonstrating that the technology of tomorrow can be powered responsibly today. The framing explicitly positions digital infrastructure growth as a potential accelerant of grid decarbonisation rather than a burden on clean energy targets, a distinction that is becoming increasingly important as Australian policymakers and communities debate the net impact of data centre expansion on the energy transition.

Community and Grid Benefits

 

The Riverina district of New South Wales receives direct economic and infrastructure benefits from the Mulwala Solar Farm, including construction employment, local procurement and long-term contribution to grid stability in a region that will increasingly host renewable generation as Australia's energy mix transitions. The project's injection of new capacity into the National Electricity Market provides grid-wide benefits that extend beyond the direct parties to the PPA, contributing to Australia's Renewable Energy Zone framework and supporting the broader buildout of transmission and generation needed for the energy transition. Damien Spillane, Chief Customer and Innovation Officer at AirTrunk, said hyperscale data centres can help accelerate Australia's energy transition by supporting investment in new renewable energy and strengthening long-term energy security.

Catriona McLeod, Managing Director of European Energy Australia, said partnerships like this one give the industry confidence as it develops more solar and wind farms, describing the collaboration as a perfect example of how major technology companies and renewables developers can work together to support the energy transition. The confidence signal provided by a committed long-term corporate PPA from a creditworthy counterparty such as Google is commercially significant for renewable energy developers seeking to underpin project finance for new assets in an environment where merchant power price risk can be difficult to manage. This demand signal supports the financial viability of new renewable development that benefits the grid as a whole.

Outlook for Technology-Renewable Energy Partnerships in Australia

 

The Mulwala Solar Farm completion reinforces a growing pattern in Australia in which hyperscale technology companies are partnering with local renewable developers to fund new generation capacity as a direct response to their data centre electricity demand. Australia's strong solar and wind resources, combined with ambitious national renewable energy targets and growing digital economy investment, create a natural alignment between technology company clean energy procurement needs and the country's infrastructure development priorities. Projects that combine new renewable generation with direct demand from digital infrastructure operators are well positioned to attract both development finance and policy support.

Whether the Mulwala model can be replicated at larger scale across Australia's major renewable energy zones will depend on the continued growth of technology company data centre investment, the pace of grid connection approvals and the development of the transmission infrastructure needed to connect new renewable generation with demand centres. Sustained replication would accelerate Australia's clean energy buildout while ensuring that digital economy growth contributes positively to rather than straining the country's grid decarbonisation trajectory. The three-party collaboration between Google, AirTrunk and European Energy Australia provides a commercially and operationally proven template for similar partnerships across the Australian energy market.
