Technical details

Part of the Pieman River scheme that comprises four hydroelectric power stations, the Mackintosh Power Station is the second station in the scheme. The power station is located aboveground at the foot of the rock-filled concrete faced Mackintosh Dam across the Mackintosh River and the Tullabardine Dam across the Tullabardine Creek that together form Lake Mackintosh. Water from the lake is fed to the power station by a 200-metre (660 ft)-long single tunnel.[2]

The power station was commissioned in 1982 by the Hydro Electric Corporation (TAS) and the station has one Fuji Francis turbine, with a generating capacity of 81 megawatts (109,000 hp) of electricity. The station output, estimated to be 394 gigawatt-hours (1,420 TJ) annually,[1] is fed to TasNetworks' transmission grid via a 13.8 kV/220 kV Fuji generator transformer to the outdoor switchyard.[3]

The water discharged from Mackintosh Power Station flows into Lake Rosebery for use in the Bastyan Power Station.[2]
