The Fisher Power Station is a conventional hydroelectric power station located in north-western Tasmania, Australia.
Technical details
[edit]Part of the Mersey–Forth scheme that comprises eight hydroelectric power stations, the Fisher Power Station is the second station in the scheme. The power station is located in the upper reaches of the Fisher River. The station is supplied with water from Lake Mackenzie, supplemented by water run-off from the plateau and by water pumped from Yeates Creek and Parsons Falls pumping stations. Water flow to the station is via a 6.5-kilometre (4.0 mi)-long flume, siphon and canal and then a 5.2-kilometre (3.2 mi)-long vertical shaft, inclined shaft, tunnel and surface penstock. The water descends 650 metres (2,130 ft) from the lake to the power station and then flows 4 kilometres (2.5 mi) before flowing into Lake Parangana (see Parangana Power Station).[2]
The power station was commissioned in 1973 by the Hydro Electric Corporation (TAS) and the station has one Fuji Pelton turbine, with a generating capacity of 46 megawatts (62,000 hp) of electricity. The station output, estimated to be 240 gigawatt-hours (860 TJ) annually,[1] is fed through an 11 kV air-blast circuit breaker to TasNetworks' transmission grid via an 11 kV/220 kV Siemens generator transformer T1 and a second transformer T2, accepts the station 22 kV output from Rowallan Power Station.[3]
