Mount Piper Power Station is acoal powered power station with twosteam turbines with a combinedgenerating capacity of 1,400MW ofelectricity. It is located nearPortland, in the Central West ofNew South Wales,Australia and owned byEnergyAustralia, a subsidiary ofCLP Group. On 23 September 2021, it was announced that the closure of the power station is being brought forward from 2042 to 2040 at the latest. The power station employs 250 workers.[1] In 2024,Peter Dutton[broken anchor] said he intends, if elected, to build one of seven government-owned nuclear power plants on this site, to be operational by 2035–2037.[2]
The first generator (Unit 2) was completed in 1992, and the second (Unit 1) in 1993. Units 3 and 4, although planned, were not built. It was the last power station built by the Electricity Commission of New South Wales (a body since abolished). Much of the design work done was undertaken in-house by the commission.
In 2009 Delta Electricity (the government owned enterprise that previously owned and managed the power station as a commercial entity) unofficially re-rated the units at Mount Piper from their original 660MW to 700MW.[3]
In 2007 & early 2008 there was public talk of 'completing' the power station by using modern super-critical, dry-cooling tower, coal-fired units of up to 1000MW capacity which uses much less water from surrounding rivers.[4]
On 7 April 2010 theNew South Wales Department of Planning announced that approval had been given toDelta Electricity to 'complete' the station by installing 2000 MW of new generating capacity.[5] A 500 MW / 2,000 MWhgrid battery is planned for the power station.[6]
Mount Piper draws its cooling water fromLyell Dam andThomsons Creek Dam, both purpose-built for the station. Lyell Dam is located on theCoxs River 20 kilometres (12 mi) away. Large pumps draw water from the dam and transfer it to a pipeline built between Thompsons Creek Dam and Mount Piper. The power station taking what water it needs and the excess flowing into Thompsons Creek Dam. When no pumps are in service the water supply to the power station is gravity fed from Thompsons Creek Dam.
Carbon Monitoring for Action estimates this power station emits 9.08 million tonnes ofgreenhouse gases each year as a result of burningcoal.[7] The National Pollutant Inventory[8] provides details of other pollutant emissions, but, as at 23 November 2008, notCO2.
