The Paloona Power Station is a conventional hydroelectric power station located in northern Tasmania, Australia.

Technical details

Part of the Mersey–Forth scheme that comprises seven hydroelectric power stations, the Paloona Power Station is the final station in the scheme. The power station is located immediately below the rock-filled concrete faced Paloona Dam which forms Lake Paloona. Water from the lake is fed to the power station by a short single penstock under the dam.[2]

The power station was commissioned in 1972 by the Hydro Electric Corporation (TAS) with a Fuji Kaplan turbine, with a generating capacity of 30 megawatts (40,000 hp) of electricity.[3]

In 2014 the turbine was upgraded to a more efficient Andritz Kaplan turbine, which also has a generating capacity of 30 megawatts (40,000 hp) of electricity.[4]

The station output, estimated to be 151 gigawatt-hours (540 TJ) annually,[1] is fed to TasNetworks' transmission grid via an 11 kV/110 kV Siemens generator transformer to the outdoor switchyard.[5]
