Australia’s biggest coal-fired power station, Eraring in Lake Macquarie, will stay open until April 2029. Origin Energy, which runs the plant, had agreed earlier to close it in August 2027. The extension adds two more years. The NSW environment minister, Penny Sharpe, said this move helps meet the state's 2030 emissions targets while ensuring power security. Sharpe said, “Origin’s decision gives certainty to workers, the market and energy consumers across the state, as well as contributing to NSW’s 2030 emissions reduction target.” The plan comes after the Australian Energy Market Operator warned of possible energy shortfalls from 2027-28 if Eraring shut as planned. Origin CEO Frank Calabria said running Eraring longer gives “more time for renewables, storage and transmission projects” to be ready. He added: “It reflects uncertainty regarding the reliability of Australia’s ageing coal and gas fleet.” Climate advocates criticized the decision. The NSW Greens’ environment spokesperson, Abigail Boyd, called it a “disaster” for climate targets. She said running Eraring for two more years would produce “16TWh” of electricity and push the state further from emissions goals. The state aims to cut emissions by 50% below 2005 levels by 2030 and reach net zero by 2050. Other voices warned the extension shows the need to speed up green energy projects. However, the NSW opposition said the announcement helps energy security but reveals broader issues with renewables rollout. The Eraring plant has operated at full capacity since 1984 and produces 2,880 MW. About half of Australia’s electricity comes from black coal-fired power stations like Eraring.
