The Devils Gate 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 Devils Gate Power Station is the sixth station in the scheme. The power station is located below the double-arched concrete Devils Gate Dam which forms Lake Barrington. Water from the lake is fed to the power station by a 150-metre (490 ft) single penstock tunnel.[2][3]
The power station was commissioned in 1971 by the Hydro Electric Corporation (TAS) and the station has one Boving Francis turbine, with a generating capacity of 63 megawatts (84,000 hp) of electricity. The station output, estimated to be 314 gigawatt-hours (1,130 TJ) annually,[1] is fed to Transend Networks’ transmission grid via an 11 kV/110 kV Siemens generator transformer to the outdoor switchyard.[4]
Recreation
Lake Barrington is a world famous rowing venue that hosted the 1990 World Rowing Championships. The dam is 84 metres (276 ft) high. It is one of the thinnest concrete arch dams in the world.[3]
