Langvann Hydroelectric Power Station

The Langvann Hydroelectric Power Station (Langvann kraftverk or Langvann kraftstasjon) is a hydroelectric power station in the municipality of Gildeskål in Nordland county, Norway. It is sometimes referred to as the Langvatn kraftverk, which should not be confused with the Langvatn Hydroelectric Power Station in Rana.

The plant utilizes a drop of 64 m between two lakes: Fellvatnet (Roavggojávrre), regulated between an elevation of 393 m and 333 m, and Langvatnet (Gåddumjávrre), regulated between an elevation of 331 m and 299 m.

The plant has a 5 MW turbine and an average annual production of about 21 GWh. Its catchment area is 93 km2. The plant is owned by Salten Kraftsamband and it came into operation in 1979. The plant is built into the mountainside at the end of a drain tunnel and the water it discharges is later used by the Sundsfjord Hydroelectric Power Station.
