Overview
- On Wednesday, Aug 5, Energy Minister Chris Bowen told the National Press Club the Commonwealth will use all available federal powers and has formally asked the Australian Energy Market Commission to draft rules forcing large data centres to underwrite new renewable generation and pay for transmission connections.
- The AEMC has advised staged national reforms that would require large developers to register with the market operator, prove they have dedicated additional renewable capacity, accept monitoring, and apply lower standards for smaller sites under about 30 megawatts.
- Queensland and the Northern Territory have publicly rejected parts of the plan and argued states should be free to consider gas-fired options, with NT ministers calling federal limits on gas 'overreach', while Bowen said proposals relying solely on gas would not meet the minimum standards.
- Industry groups broadly support the user-pays principle but want credit where data centres fund shared assets used by others and seek phased or scaled rules to avoid onerous upfront costs for some projects.
- The government plans to take legislation to parliament in early 2027 after AEMC consultation and staged implementation, a step that could raise upfront costs for new projects, speed new renewable build, and shape where and how major sites such as those proposed for Darwin and Bundey proceed.
