Liddell Power Station is a coal-powered thermal power station with four 500 megawatts (670,000 hp) GEC (UK) steam driven turbo alternators for a combined electrical capacity of 2,000 megawatts (2,700,000 hp). Commissioned between 1971 and 1973, the station is located at Lake Liddell near Muswellbrook, in the Hunter Region, New South Wales, Australia.
Prior to September 2014 Liddell power station was part of NSW Government power producer, Macquarie Generation.[1] Macquarie Generation was acquired by AGL Energy in September 2014.[2]
History
The first generator was completed in 1971, two more in 1972, and the fourth in 1973. At the time of its completion, Liddell was the most powerful generating station in Australia. The completion of Liddell aided in the retirement of earlier power stations in Sydney, such as Bunnerong.
Originally fitted with the then-standard electrostatic precipitators for dust collection, the more efficient Fabric Filters (as used at Eraring, Munmorah units 3 and 4,Vales 5+6, Bayswater and Mount Piper) were retrofitted in the early 1990s, reducing particulate emissions to a barely visible level.
Much of the coal is supplied by overland conveyors from mines it shares with the nearby Bayswater Power Station. Liddell was the first major power station in New South Wales to be built inland, using fresh water for cooling instead of the more abundant salt water used in coastal power stations. To accommodate this, Lake Liddell was expanded to provide more water.
AGL announced in 2015 and reaffirmed in 2017 that it intends to close the Liddell Power Station in 2022.[3] The closure of this and other coal-burning power stations in Australia has led to the Prime Minister of Australia, Malcolm Turnbull, to seek advice from the Australian Energy Market Operator on extending the life of a number of them,[4] to head off future power shortages.[5]
Alternative fuel sources
In addition to the coal-fired steam turbines, Liddell runs two 25 MW oil-fired gas turbines[6] and an 0.85 MW mini-hydroelectric generator.[6][7] It is also "licensed to co-fire plant biomass and coal to produce electricity", which essentially means it can use sawdust and wood shavings from the nearby timber industry as a portion of its fuel, replacing up to 5% of its coal requirements.[8][9] In practice, however, biomass accounts for only about 0.5% of Liddell's output.[citation needed]
In 2007 a project commenced at Liddell to replace some of the station's boiler feed-water by hot water from a solar thermal array.[10] As of March 2007, the project was at a second-stage prototype but had not been connected to the power station. Subsequently the 9 MW solar section was added to the Liddell coal-fired generator, but has now effectively been closed. Analysts say the incentive to use solar boost has also been reduced by removal of carbon price and excess coal supply.[11]
Greenhouse emissions
Carbon Monitoring for Action estimates this power station emits 14.70 million tonnes of greenhouse gases each year as a result of burning coal.[12] In 2010 the Australian Government introduced a Carbon Pollution Reduction Scheme to help combat climate change. The scheme has impacted on emissions from power stations. The National Pollutant Inventory provides details of a range of pollutant emissions, including CO, estimated at 1,000,000 kilograms (2,200,000 lb) for the year ending 30 June 2011.[13]
