Liddell retirement cuts pollution, not reliability, says NCC

The Nature Conservation Council of New South Wales (NCC), the states leading environmental advocacy organisation, has today highlighted that over 1100 MW of dispatchable capacity has been added to the NSW electricity grid since the closure of Liddell was announced.

“The retirement of the Liddell coal-fired power station over the next week is a case study in cleaning up the state’s climate pollution,” NCC CEO Jacqui Mumford said today.

“Since AGL announced the retirement date for Liddell in 2015, 19 energy storage projects have been completed across the country, and another 33 are under construction.” [1]

In NSW alone, 1190 MW of firm capacity has been added since Liddell’s retirement was announced, in excess of the 750 MW of average availability Liddell provided in 2022. See table below.

“We can have a safe climate for our kids and a reliable power grid, and Liddell’s closure is a demonstration of how we must do this” said Mumford.

“Replacing this power station has huge benefits, including a massive 8% drop in NSW’s greenhouse gas emissions,”[2]

“That’s equivalent to swapping 60% of the cars in NSW with zero emissions EVs. [3]

“The impact of Lidell’s announced closure was to accelerate investment in renewables across the state.”

“Commentary on keeping old and polluting coal fired power plants open longer than scheduled is only serving to spook investors and make it harder to secure the clean energy generation we need.”

“This has been planned for and the NSW energy system is ready.”
