The Devils Gate Power Station is a conventional hydroelectric power station located in north-western Tasmania, Australia. The dam is 84 metres (276 ft) high. It is one of the thinnest concrete arch dams in the world.
Technical details
Part of the Mersey–Forth scheme that comprises seven hydroelectric power stations, the Devils Gate Power Station is the sixth station in the run-of-river 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.
The power station was commissioned in 1969 by the Hydro Electric Corporation and 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, is fed to TasNetworks' transmission grid via an 11 kV/110 kV Siemens generator transformer to the outdoor switchyard.
Recreation
Lake Barrington is a world-famous rowing venue that hosted the 1990 World Rowing Championships.
Engineering heritage
The dam received a Historic Engineering Marker from Engineers Australia as part of its Engineering Heritage Recognition Program.
