The Tungatinah Power Station is a traditional hydroelectric facility situated within Tasmania's Central Highlands area. It is positioned on the catchment of the Upper River Derwent and is both owned and managed by Hydro Tasmania.
Technical details
As one of eleven hydroelectric plants forming the Derwent scheme, Tungatinah ranks as the second station in sequence and is located above ground adjacent to the Nive River. The station's intricate headworks system comprises multiple dams—including Bronte Lagoon (Bronte Dam), Bradys Lake (Bradys Dam), Lake Binney, and Tungatinah Lagoon—along with an array of tunnels, canals, pipelines, flumes, control gates, and a pump station. Water flows from Tungatinah Lagoon down through five steel penstocks to reach the power generation facility.
Constructed between 1953 and 1956 under the direction of Hydro Tasmania, this station contains five Boving Francis turbines that collectively deliver a capacity of . Each turbine is equipped with a semi-embedded spiral casing, utilizing a spherical rotary inlet valve to regulate flow and a relief valve designed to prevent excessive pressure. The plant generates an annual output near . Electricity produced is transmitted to TasNetworks through five 11 kV/110 kV three-phase GEC generator transformers connected to an outdoor switchyard.
Following turbine operation, water is released into the Nive River, where it merges with discharges from Tarraleah Power Station. This combined flow supports six additional Lower Derwent hydroelectric stations.
