Australia Sets Renewable Power Requirement for New Data Centres With Limited Fossil Fuel Exemptions

Australia’s federal government has reinforced plans to require new large data centres to support their electricity demand with renewable energy, while allowing a limited pathway for state-owned energy providers to seek exemptions where fossil fuel generation can be demonstrated to be cheaper.

Climate Change and Energy Minister Chris Bowen said the proposed national standards would apply across every Australian state and territory, rejecting suggestions that Queensland or the Northern Territory had secured broad exemptions allowing new data centres to rely on coal or gas.

The clarification followed a National Cabinet meeting on 26 August, where federal, state and territory leaders agreed to develop consistent mandatory standards covering the energy, water and land-use impacts of large data centres. The federal government plans to legislate the broader artificial intelligence regulatory framework in early 2027.

Under the proposed approach, large data centres would generally be required to match their electricity demand with new renewable generation, supported by sufficient firming capacity to maintain reliable operations.

Bowen has said data centres will use Australia’s Renewable Electricity Guarantee of Origin framework to demonstrate that their electricity consumption is being supported by renewable generation that would not otherwise have been developed. Companies could meet this obligation through mechanisms including power purchase agreements or direct investment in new renewable projects.

The government also expects operators to demonstrate that they have adequate firmed electricity available to cover their load. Storage and other firming technologies could contribute, while gas-fired generation may continue to have a role as backup capacity during periods when renewable generation is insufficient.

Fossil Fuel Option Subject to Federal Approval

The National Cabinet negotiations introduced some flexibility for jurisdictions with state-owned electricity systems.

According to Bowen, a state-owned energy company that believes it can supply a data centre more cheaply using existing generation may submit a case to the federal government. The Australian Energy Regulator would assess the proposal, including whether the non-renewable option genuinely offers a lower-cost outcome.

The Commonwealth would retain the final decision.

Bowen said this arrangement should not be interpreted as a general exemption from the renewable electricity requirements. In an ABC interview following the National Cabinet meeting, he said the federal legislation would apply nationally, and that applications involving coal or gas would need to be assessed individually.

The distinction is particularly relevant to Queensland and the Northern Territory, where political leaders have expressed interest in using existing fossil fuel resources to support data centre development.

The broader federal policy is intended not only to manage emissions but also to prevent large new electricity users from increasing costs or reliability risks for households and other businesses. The government has previously said large data centres should underwrite new electricity supply, pay their full share of grid connection costs and be capable of reducing demand when necessary to support grid stability.

Data Centre Electricity Demand is Accelerating

The regulatory debate comes as Australia faces a sharp increase in electricity consumption from digital infrastructure.

The Australian Energy Market Operator, or AEMO, estimates that data centre electricity consumption in the National Electricity Market could rise from approximately 5 terawatt-hours in 2025-26 to 34 TWh in 2035-36.

That would increase the sector’s share of electricity supplied through the grid from around 3% to approximately 13% within a decade.

Development activity is already substantial. At the end of the March 2026 quarter, 11 large data centre projects with a combined maximum demand of 5.4 GW were progressing through the transmission connection process. Around 60% of that proposed capacity was located in New South Wales and 40% in Victoria.

AEMO has identified data centres as one of the fastest-growing sources of electricity demand in both the National Electricity Market and Western Australia’s Wholesale Electricity Market.

The challenge for policymakers is therefore not simply securing enough electricity for individual facilities. Large clusters of data centres can influence transmission investment, generation requirements, grid stability and wholesale electricity prices.

Renewable Expansion Will Need to Keep Pace

Australia’s electricity system is simultaneously undergoing a transition away from ageing coal-fired generation toward renewable energy, batteries, transmission infrastructure and other flexible resources.

AEMO reported that around 40 GW of new generation and storage capacity is either committed or anticipated, with a further 33 GW supported by government programs. However, continued investment will be required as electricity demand rises and existing thermal generators retire.

Data centre development adds another major variable to those forecasts.

If operators are required to contract additional renewable capacity rather than simply purchasing electricity already available in the market, the sector could become a significant source of long-term demand for new solar, wind and storage projects.

However, implementation will be important. Regulators will need to establish how additional renewable generation is verified, how firming requirements are calculated and what evidence must be provided when state-owned electricity companies seek exemptions.

The government will also have to coordinate energy rules with planned standards covering water consumption and land use, two other increasingly significant issues for large data centre developments.

Data Centres Emerge as Part of Australia's Climate Policy

The new rules are being developed while Australia continues to reduce emissions from electricity generation.

Government figures released on 28 August show national greenhouse gas emissions fell 1.6% in the year to March 2026 to an estimated 455.6 million tonnes. Electricity-sector emissions declined by 5.6 million tonnes, or 3.7%, as increasing solar, wind and battery deployment displaced coal and gas generation.

Australia is targeting a 43% reduction in emissions below 2005 levels by 2030, net-zero emissions by 2050 and a 62% to 70% reduction by 2035.

Against that backdrop, rapidly expanding AI and data centre electricity consumption is becoming part of the country’s wider energy transition challenge.

The proposed national standards represent an attempt to link digital infrastructure growth directly with investment in additional electricity supply. For developers, utilities and renewable energy companies, the final legislation could therefore influence not only where new data centres are built, but also how billions of dollars in associated energy infrastructure are financed and developed.
