Australian Data Center Power Draw to Increase Sevenfold by 2036, Energy Market Operator Reports

Australia's data center sector is projected to consume 13% of the nation's primary power market by the 2035-36 fiscal year, expanding from 3% today in a nearly sevenfold increase over the next decade, according to the Australian Energy Market Operator (AEMO). The forecast, detailed in AEMO's latest annual Electricity Statement of Opportunities and first reported by The Next Web via Bloomberg reporting by Keira Wright, highlights a dramatic shift in energy distribution as the country concurrently retires legacy fossil fuel infrastructure.

According to the report, facilities dedicated to artificial intelligence and cloud computing will consume 34 terawatt hours of electricity annually from the National Electricity Market by 2035-36. This demand spike comes as Australia plans to shut down approximately 13 gigawatts of coal-fired generation and almost 2 gigawatts of gas-powered capacity over the coming decade. AEMO noted that data centers present distinct challenges for grid operators because their energy draw remains constant across seasons and times of day, pressing hardest against grid capacity during off-peak hours when overall system generation dips.

Grid reliability has seen recent improvements due to accelerated investments in renewable infrastructure and storage capacity. Approximately 9 gigawatts of new generation and energy storage reached full operational capacity during the 2025-26 period, marking double the capacity brought online during the previous year. Building on momentum from August 2025 when record additions of clean power alleviated summer blackout risks, the expanded buildout seeks to offset retiring baseload facilities.

Addressing the transition, AEMO Chief Executive Daniel Westerman highlighted that substantial new capacity is slated for delivery between now and the early 2030s to replace outgoing power units and support rising demand. Westerman warned, however, that securing a subsequent wave of infrastructure investment beyond 2030 will be critical for maintaining overall system reliability across the grid network.

Despite the aggressive sector projections, actual buildout numbers remain volatile. Data center developers have recently cancelled more than a third of the proposed projects featured in AEMO’s operational forecast from last year. Even with these cancellations, financial forecasts remain massive, with Commonwealth Bank of Australia projecting that total capital expenditure on Australian data center construction could climb to A$150 billion (approximately $108 billion) by 2030.

The rapid scaling of computing infrastructure has intensified political disputes over grid access and environmental policy. Federal leaders are pushing for new data centers to run strictly on renewable energy sources, but regional administrations in Queensland and the Northern Territory have resisted federal mandates. Prime Minister Anthony Albanese is slated to address these concerns at a national cabinet meeting, promising state premiers that a proposed federal AI law will work alongside state regulations rather than override local oversight, following a setback in July when state disagreements stalled nationwide data center standards.

Industry observers, including the Clean Energy Finance Corporation and the United States Studies Centre, have warned that delays in grid expansion could trigger supply bottlenecks, elevate consumer electricity rates, and force prolonged reliance on fossil fuels. To bypass connection queues, some developers are considering standalone infrastructure, such as a proposed $28 billion off-grid AI data center located on a gas-supplied outback site. Australia's infrastructure strain mirrors broader global challenges, following connection halts in Texas, moratorium debates in Scotland, and grid congestion across European markets that has pushed 63% of new development beyond established hubs.
