The Rowallan Power Station is a traditional hydroelectric facility located in the northwestern region of Tasmania, Australia, positioned roughly south of the town of Liena.
Technical details
As the initial facility within the eight-station Mersey–Forth hydroelectric system, Rowallan Power Station lies approximately downstream from Rowallan Dam, which creates Lake Rowallan. This dam functions as one of the two principal headwater reservoirs managing water supply to four hydroelectric plants situated further downstream.
Commissioned in 1971 by the Hydro Electric Corporation, this power station utilizes a single Maier Francis turbine with a generating capacity of . It produces an estimated annual energy output of , which is transmitted into the TasNetworks grid through a 22 kV/110 kV transmission line connecting to the switchyard transformer.
Rowallan Lake
Rowallan Lake extends over in length and encompasses an area of , resting at an elevation of above sea level. The lake is flanked by Clumner Bluff and Howells Bluff. Overseen by the Tasmanian Inland Fisheries Service as a managed trout fishery, it is regularly stocked with Brown trout and Rainbow trout, while also sustaining native fish species including Climbing galaxias, Spotted galaxias, and River blackfish.
Additionally, the lake provides access to surrounding highland regions such as the Walls of Jerusalem National Park. In 2010, concerns were raised about the structural condition of the embankment dam, leading to increased examination of its safety.
Etymology
Both the power station and lake derive their names from Thomas Corbett, 2nd Baron Rowallan, who served as a former Governor of Tasmania.
