The Wivenhoe Power Station is situated between the Splityard Creek Dam and Lake Wivenhoe. The Splityard Creek dam is situated in hills adjacent to Lake Wivenhoe and is about 100 metres above it.
The Wivenhoe Dam has been built across the Brisbane River about 30 kilometres north of Ipswich,
During the pumping phase in the operating cycle the generator operates as an electric motor driving the pump to lift water from Lake Wivenhoe to the upper storage of Splityard Creek Dam. When peak demand for electricity occurs the flow of water is reversed, flowing from the upper to the lower storage and driving the turbine generator to generate electricity.
The Splityard Creek dam has sufficient capacity of 500 MW for 10 hours of continuous power generation. It takes about 14 hours of pumping to refill it.
Wivenhoe Dam Power Station was commissioned in 1984. It was transferred from Tarong Energy to CS Energy )both Queensland Government instrummentalities) in 2011.
A mini hydro-electric power station with an output of 4.5 MW, powered by water from the Wivenhoe Dam, into the Brisbane River commenced operation in 2003.
