The Cethana Power Station is a conventional hydroelectric power station located in north-western Tasmania, Australia.
Technical details
Part of the Mersey–Forth scheme that comprises eight hydroelectric power stations, the Cethana Power Station is the fifth station in the scheme. The power station is located underground and is supplied with water from Lake Cethana which is fed by the outflow from the Lemonthyme Power Station on the Mersey River and the Wilmot Power Station located below Lake Gairdner, and uncontrolled flow from the Forth River. Water from the station is returned to the Forth River through a tailrace tunnel which has a tailrace gate structure at the outlet portal.
The power station was commissioned in 1971 by the Hydro Electric Corporation (TAS) and the station has one Fuji Francis turbine, with a generating capacity of 100 megawatts (130,000 hp) of electricity. The station output, estimated to be 434 gigawatt-hours (1,560 TJ) annually, is fed to the outdoor switchyard via a three single-phase 13.8 kV/220 kV Fuji generator transformer.
