Changes to national data centre rules will be considered in September. The council, which includes energy ministers from the federal government and all state and territory governments, met virtually to discuss data centre energy proposals after flagging the issue in May. Changes to national rules would be considered in September, including reforms to the way data centres reported energy use. But introducing a blanket rule for data centres' energy use could be ineffective if it was not designed with industry input, Data Centres Australia chief executive Belinda Dennett said. "A one-size-fits-all approach will not work and may well be counterproductive to renewable energy investment objectives," Ms Dennett said.
