Wivenhoe Power Station
CS Energy's Wivenhoe Power Station is a 500 megawatt, pumped storage hydroelectric plant located on the eastern side of Wivenhoe Dam, about 90 kilometres north-west of Brisbane.
Wivenhoe Power Station is the only pumped storage hydroelectric plant in Queensland. It consists of two 250 megawatt units that are the largest hydro machines in Australia and weigh 1,500 tonnes each.
Electricity is generated, absorbed and stored at Wivenhoe Power Station by recycling water between an upper reservoir (Splityard Creek Dam) and lower reservoir (Wivenhoe Dam). Water is pumped from Wivenhoe Dam into Splityard Creek Dam. To produce electricity, water is released from Splityard Creek Dam through tunnels to the turbines that drive the generators. In this way, Wivenhoe Power Station works like a giant rechargeable battery.
Wivenhoe Power Station was transferred to CS Energy’s asset portfolio on 1 July 2011 as a result of the Queensland Government’s Generator Restructure.
Commissioned in 1984, Wivenhoe Power Station has an expected life of up to 100 years and has 13 onsite employees.
