The Catagunya Power Station is a run-of-the-river[1] hydroelectric power station located in the Central Highlands region of Tasmania, Australia. The power station is situated on the Lower River Derwent catchment and is owned and operated by Hydro Tasmania.
Technical details
Part of the Derwent scheme that comprises eleven hydroelectric power stations, the Catagunya Power Station is the seventh power station in the scheme and the third power station in the lower run-of-river system. The power station is located above ground, below Lake Catagunya, a small storage created by the rock-filled Catagunya Dam on the Derwent River below its junction with the Nive River. Water from the Derwent from Liapootah Power Station and spill from Liapootah Dam flows into Wayatinah Lagoon. Water in the lagoon is diverted by a Шаблон:Convert-long tunnel to two low pressure woodstave pipelines, each Шаблон:Convert long. It then descends Шаблон:Convert through three steel penstocks to the Wayatinah Power Station. The tunnel intake structure is provided with two vertical lift, gravity close intake gates designed to cut off full flow. Each of the three steel penstocks is provided with a hilltop valve designed to close under full flow.[1][2]
The power station was commissioned in 1962 by the Hydro Electric Corporation (TAS) and the station has two Шаблон:Convert Boving Francis-type turbines, with a combined generating capacity of Шаблон:Convert of electricity. Within the station building, each turbine has a semi-embedded spiral casing, and water flow is controlled via twin radial gates installed at the entrance to each penstock and designed to cut off full flow. No inlet valves are installed in the station. The station output, estimated to be Шаблон:Convert annually,[3] is fed to TasNetworks' transmission grid via two 11 kV/220 kV ASEA generator transformers to the outdoor switchyard.[1]
Engineering heritage
The dam received a Historic Engineering Marker from Engineers Australia as part of its Engineering Heritage Recognition Program.[4]
