The Tarraleah Power Station is a hydroelectric power station located in the Central Highlands, Tasmania, Australia. It is part of the Upper Derwent Hydro Scheme and is operated by Hydro Tasmania.
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.{{cite web|url=https://www.engineersaustralia.org.au/portal/system/files/engineering-heritage-australia/other-supporting-material/Tarraleah_Nom_%2B_Cer.pdf|title=Tarraleah Power Development: 1938 to date|date=19 February 1998|work=Historic Engineering Marker Submission and Ceremony Report|publisher=Engineers Australia|access-date=4 July 2015}}{{rp|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.{{cite book |pages=76–120 |chapter=Chapter 3: On the Upper Derwent |author1=Felton, Heather |title=Ticklebelly Tales and other stories from the people of the Hydro |date=2008 | publisher=Hydro Tasmania| isbn=978-0-646-47724-4 }}

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 {{convert|25|km}} via the Tarraleah Canals.{{cite web |url=http://www.hydro.com.au/community/sites/upper-derwent-valley-area |title=Upper Derwent Valley area |work=Community |publisher=Hydro Tasmania |access-date=4 July 2015}}{{cite web |url=http://www.hydro.com.au/energy/our-power-stations/derwent-0/tarraleah-power-station |title=Derwent: Tarraleah Power Station |work=Energy |publisher=Hydro Tasmania |access-date=4 July 2015}}
