The Papenoo Hydroelectric Power Station is located near the commune of Papenoo on the island Tahiti in the overseas country of France, French Polynesia. It has an installed capacity of 28 MW and was constructed between 1989 and 1994. The hydroelectric power station is owned by Electricite de Tahiti SA. It is the largest hydroelectric power station in Tahiti.[1]
It uses water provided by five reservoirs high up in the Papenoo Valley, above the commune. Each reservoir is created on the Papenoo River or a tributary by an embankment dam. From highest in elevation to lowest; Vaitapaa Dam at Lua error in package.lua at line 80: module 'strict' not found., which lies at an elevation of 411 m (1,348 ft) above sea level, is 15 m (49 ft) tall. It withholds a reservoir of 8,000 m3 (6.5 acre·ft). Next, at an elevation of 400 m (1,300 ft), Tahinu Dam, at Lua error in package.lua at line 80: module 'strict' not found. is 33 m (108 ft) high and withholds a larger reservoir of 1,500,000 m3 (1,200 acre·ft). It is the tallest dam in Tahiti. Moving down is Vainavenave Dam at Lua error in package.lua at line 80: module 'strict' not found. which lies at 399 m (1,309 ft) above sea level, is 29 m (95 ft) tall, and withholds a reservoir of 150,000 m3 (120 acre·ft). Fourth down the valley is the Vaituoru Dam at an elevation of 200 m (660 ft) with a reservoir capacity of 100,000 m3 (81 acre·ft). It is located at Lua error in package.lua at line 80: module 'strict' not found.. Finally is the Tevaiohiro Dam at 85 m (279 ft) above sea level with a reservoir volume of 150,000 m3 (120 acre·ft). It is located at Lua error in package.lua at line 80: module 'strict' not found..[2][3]
Water from the reservoirs is sent to three separate power stations via Lua error in Module:Convert at line 272: attempt to index local 'cat' (a nil value). of penstock. The power station highest in elevation, Papenoo 1 contains four 4 MW Pelton-turbine-generators and is located at Lua error in package.lua at line 80: module 'strict' not found.. Next downstream is Papenoo 2 at Lua error in package.lua at line 80: module 'strict' not found. which contains one 4 MW Pelton turbine-generators. Lastly, Papenoo 3 contains two 4 MW Pelton turbine-generators and is located at Lua error in package.lua at line 80: module 'strict' not found..[2][3]
