History

The Upper River Derwent hydroelectric scheme was developed at a time in 1934 when the former Hydro-Electric Commission had only two working power stations.[2]: 1  In 1934 the Derwent Valley Power Development power scheme was approved by the Parliament of Tasmania with the Tarraleah Power Station as the first completed power station of that scheme.[3]

Ticklebelly Flat, the nickname for the married quarters at Tarraleah Camp number 2 in the 1930s, is a name for the history of Hydro Tasmania by Heather Fenton, known as Ticklebelly Tales.[4]

Power station

The outdoor switchyard located adjacent to the Tarraleah Power Station.

Part of the Derwent scheme that now comprises eleven hydroelectric power stations, the Tarraleah Power Station is located aboveground on the west bank of the Nive River downstream from the village of Tarraleah and a short distance from the Lyell Highway. The station draws its water from a variety of sources. Water from the concrete arched Clark Dam across the River Derwent that forms Lake King William flows from the lake and also from the Butlers Gorge Power Station around 25 kilometres (16 mi) via the Tarraleah Canals.[5][6][7]

The power station was opened in July 1938[8][9][10][11] and has six Pelton-type turbines, with a generating capacity of 90 megawatts (120,000 hp) of electricity. The station output is fed to the transmission grid via 11 kV metal clad switchgear and two 11 /110 kV 75MVA 3-phase power transformers.[6]

Engineering heritage award

The Tarraleah hydro-electric development received a Historic Engineering Marker from Engineers Australia as part of its Engineering Heritage Recognition Program.[12]
