Liapootah Power Station
The Liapootah Power Station is a hydroelectric facility utilizing run-of-the-river technology, situated within Tasmania's Central Highlands region. It lies within the Lower River Derwent catchment area and is under the ownership and management of Hydro Tasmania.
Technical details
As a component of the Derwent hydroelectric system, which comprises eleven power stations, Liapootah is the initial station in the lower run-of-river segment. Positioned downstream of Lake Liapootah, it receives water channeled through a concrete-lined tunnel originating below the Tarraleah and Tungatinah stations. Lake Liapootah functions as a narrow run-of-river reservoir; its water level is managed by an automated drum gate designed to prevent upstream flooding at Tarraleah while optimizing hydraulic head and generation capacity without reducing dam elevation.
Commissioned in 1960 by the Hydro Electric Corporation (TAS), this power station contains three English Electric Francis turbines with a combined generating capacity of . Each turbine incorporates a fully embedded spiral casing, with flow regulated via a spherical rotary main inlet valve alongside a turbine relief valve to safeguard against excessive pressure. The estimated annual energy production is , which is delivered to the TasNetworks grid through three 11 kV/220 kV English Electric generator transformers.
