The Oldereid Hydroelectric Power Station (Norwegian: Oldereid kraftverk or Oldereid kraftstasjon) is a hydroelectric power station in Misvær in Nordland county, Norway.
The plant utilizes a drop of 321 meters (1,053 ft), drawing water from the watercourses of the Oldereid and Skred rivers. The plant uses Lake Børnup as a reservoir, regulated between an elevation of 320 m (1,050 ft) and 308 m (1,010 ft). Water is also supplied from two other lakes: Gjømmervatnet (Lule Sami: Siggajávrre), regulated between 398 m (1,306 ft) and 389 m (1,276 ft), and Mangevatnet, regulated between 472 m (1,549 ft) and 465 m (1,526 ft).
The plant has a single turbine with an installed capacity of 12 MW and an average annual production of about 60 GWh. Its catchment area is 50 square kilometers (19 sq mi). The plant is owned by Salten Kraftsamband and it came into operation in 1953. The owner has obtained a license for further development, and water from two more lakes, Tindvatn and Lurfjellvatnet, will be transferred to the power plant. The Oldereid plant replaced what were originally six smaller river plants in the area.
The municipalities of Bodø, Skjerstad, Fauske, Saltdal, and Sørfold started negotiations on building a conventional hydroelectric power station in 1945. The options were Daja in the Sulitjelma drainage system or the Oldereid drainage system, but the authorities were unable to reach an agreement, and so the Norwegian Water Resources and Energy Directorate had to make the choice. The decision was made in 1948 and the size of the facility was determined by the guidelines set up for electricity supply. Only Bodø and Skjerstad approved the decision, and Salten Kraftlag was founded in April 1949. Bodø became a shareholder with 90% ownership and Skjerstad with 10%.
