Kjensvatn power plant is an upgrade and expansion project in Rana power plant's regulated water area in Rana Municipality in Nordland County.
Kjensvatn power plant uses a height of fall of 70 metres between Lake Gressvatn and Lake Kjensvatn. In addition to water from Lake Gressvatn, water is also transferred from Lake Durmålsvatn and the stream Gråfjellbekken. A tunnel from Leirskardalen Valley has been extended and serves both as a diversion tunnel to Lake Gressvatn and head race tunnel to the power plant. The waterways and power plant are all located inside the mountain.
The power plant is equipped with a Francis turbine that can take in 20 cubic metres of water per second.
Construction began in the spring of 2012. The power plant came on line for the first time on 24 July 2014.
