Splityard Creek Dam, of earth and rock construction, forms the upper reservoir for a power station.
Owned and operated by CS Energy, Wivenhoe Power Station is located on the eastern side of Wivenhoe Dam, north west of Brisbane. The station, which began commercial operation in 1984, was Queensland’s first pumped storage hydro-electric plant.
The dam has a capacity of 28 700 megalitres, enough for the power station to run at full load for about 10 hours. Using both pumps, this water can be replaced in about 14 hours. The pumped storage power station consists of two circular concrete silos, each of about 32 metres internal diameter. Each of the silos houses a 250MW turbine generator and pump set, giving a total capacity of 500MW.
