Hitia'a Hydroelectric Power Station

The Hitia'a Hydroelectric Power Station, also called Faatautia Hydroelectric Power Station, is located near the commune of Hitia'a on the island Tahiti in the overseas country of France, French Polynesia. It has an installed capacity of 7.54 MW and was constructed between 1983 and 1988. The hydroelectric power station is owned by Electricite de Tahiti SA.

It uses water provided by three reservoirs high up in the Faatautia Valley, above the commune. Each reservoir is created by an embankment dam. Hitia'a 2 Dam at -17.62891°N, -149.34543°W, which lies at an elevation of 637 m above sea level, is 19 m tall. It withholds a reservoir of 110000 m3. Next, at an elevation of 530 m, Hitia'a 3 Dam at -17.63087°N, -149.33571°W is also 19 m high but withholds a larger reservoir of 600000 m3. Finally, Hitia'a 1 Dam at -17.62672°N, -149.33659°W lies at 511 m above sea level, is 10 m tall, and withholds a reservoir of 11000 m3. Water from the reservoirs is sent to the power station via a 11.5 km long penstock. The power station contains an array of six Pelton turbine-generators which include a 300 kW, 140 kW, 100 kW, 1 MW and two 3 MW units.
