The power station is situated on the Lower River Derwent catchment and is owned and operated by Hydro Tasmania.

It then descends 56 metres (184 ft) through three steel penstocks to the Wayatinah Power Station.

Each of the three steel penstocks is provided with a hilltop valve designed to close under full flow.

[2][3] The power station was commissioned in 1962 by the Hydro Electric Corporation (TAS) and the station has two 25-megawatt (34,000 hp) Boving Francis-type turbines, with a combined generating capacity of 48 megawatts (64,000 hp) of electricity.

The station output, estimated to be 237 gigawatt-hours (850 TJ) annually,[1] is fed to TasNetworks' transmission grid via two 11 kV/220 kV ASEA generator transformers to the outdoor switchyard.
