Technical details

Part of the Mersey – Forth run-of-river hydro scheme that comprises seven hydroelectric power stations, the Wilmot Power Station is the fourth station in the scheme. The power station is located on the foreshore of Lake Cethana. Water stored at Lake Gairdner is transferred east approximately 4.5 km (2.8 mi) to the station via a tunnel and a surface penstock. Water is then discharged from the station into Lake Cethana. [2]

The power station was commissioned in 1971 by the Hydro Electric Corporation (TAS). It has one turbine, with a generating capacity of 32 megawatts (43,000 hp) of electricity.

The station output, estimated to be 137 gigawatt-hours (490 TJ) annually, [1] is fed to TasNetworks' transmission grid via an 11 kV/220 kV Siemens generator transformer to the outdoor switchyard. [3]
