The '''Cluny Dam''' is a [[gravity dam]] across the [[Derwent River (Tasmania)|Lower River Derwent]], located in the [[Central Highlands (Tasmania)|Central Highlands]] region of [[Tasmania]], Australia. Completed in 1967, the resultant [[reservoir]], Cluny Lagoon, was established for the purpose of generating [[hydroelectricity]] by the '''Cluny Power Station''', a [[Hydroelectricity#Conventional (dams)|conventional]] hydroelectric [[power station]]. The dam and power station are owned and operated by [[Hydro Tasmania]].
== Dam overview == Built by the [[Hydro Tasmania|Hydro Electric Corporation (TAS)]] in 1967, the concrete dam wall is {{convert|30|m}} high and {{convert|204|m}} long. When full, the reservoir has capacity of {{convert|4880|ML|acre.ft|lk=on}} and covers {{convert|80|ha}}, drawn from a [[drainage basin|catchment area]] of {{convert|2971|km2}}. The [[Spillway#Types|uncontrolled spillway]] has a flow capacity of {{convert|4248|m3/s}}. The reservoir receives water from the [[Repulse Power Station|Repulse Dam]].<ref name=ANCOLD>{{cite web |title=Register of Large Dams Australia-2015 |date=January 2022 |access-date=2026-03-05 |url=https://ancold.org.au/information-resources/dams-information/ |work=[[ANCOLD]] |format=[[Microsoft Excel|Excel]]. Requires download. Row 113}}</ref>
== Hydroelectric power station == Part of the [[River Derwent (Tasmania)|Derwent]] scheme that comprises eleven hydroelectric power stations, the Cluny Power Station is the tenth power station in the scheme. The power station is located aboveground below the Cluny Lagoon. The facilities at the Cluny Power Station are simple and include the dam, intake structure with intake gate designed to cut off full flow, a short [[penstock]] which is integral with the dam, power station building, generator equipment and associated facilities.<ref name=hydro>{{cite web |url=https://www.hydro.com.au/clean-energy/our-power-stations/derwent |title=Derwent |work=Energy |publisher=[[Hydro Tasmania]] |access-date=19 June 2023 |archive-url=https://web.archive.org/web/20220217174205/https://www.hydro.com.au/clean-energy/our-power-stations/derwent |archive-date=17 February 2022 |url-status=live }}</ref><ref name=TECH>{{cite web |url=https://www.hydro.com.au/docs/default-source/clean-energy/our-power-stations/power-station-fact-sheets/cluny-power-station-fact-sheet.pdf?sfvrsn=2bcd9b28_2 |title=Cluny Power Station Fact Sheet: Technical fact sheet |work=Energy: Our power stations |publisher=[[Hydro Tasmania]] |access-date=19 June 2023 |archive-url=https://web.archive.org/web/20230619052620/https://www.hydro.com.au/docs/default-source/clean-energy/our-power-stations/power-station-fact-sheets/cluny-power-station-fact-sheet.pdf?sfvrsn=2bcd9b28_2 |archive-date=19 June 2023 |url-status=live }}</ref>
The power station was commissioned in 1967 by the Hydro Electric Corporation and has a single Boving [[Kaplan turbine|Kaplan-type]] [[Water turbine|turbine]] with a generating capacity of {{convert|18.6|MW|e3hp|lk=on}} of electricity. Within the station building, the turbine has a four-bladed runner and concrete spiral casing. Pre-stressed cables passing through the stay vanes anchor the spiral casing and form part of the station foundation. No inlet valve is installed in the station. The station output, estimated to be {{convert|90|GWh||lk=on}} annually, is fed to [[TasNetworks]]' transmission grid via an 11 k[[voltage|V]]/220 kV [[Siemens]] generator transformer to the outdoor switchyard.{{r|TECH}}
Water discharged from the Cluny Power Station flows into the River Derwent.<ref name=hydro/>
