Stokkelandsåna power plant

The Stokkelandsåna river originates in the hills east of Kvinesdal and flows into the Litleåna river at Frivoll/Espeland. The river has a large and flat catchment area with an even water flow, and is well-suited for creating value of various types.

In the past, there have been mills in the river. In the mid-80s, the river was assessed as a hydroelectric project under the national plan. In 2005, a contract was signed with Småkraft, which assumed the risk, the work with the licensing process and the development itself. NVE granted a license in the summer of 2007. Excavators arrived in December 2008, and in May 2010, the power plant was ready to deliver its contribution in the form of new renewable energy and local business revenues. With its natural stone walls and a glass façade, the station building has an attractive exterior and has been nicely adapted to the terrain. Stokkelandsåna power plant has become a facility that both landowneres and Småkraft can be proud of!

Stokkelandsåna power plant utilises a 138-metre waterfall into Stokkelandsåna river located in Kvinesdal municipality in Vest-Agder county. The Stokkelandsåna river runs into the Litlåna river, which is a tributory to the Kvina river that flows into the Feda Fjord.

The Pelton turbine has 6 nozzles with a maximum flow rate of 2.7 m3/s. It runs a 3500 kVa, 6600V generator. All power is converted to 22 kV and delivered to the grid. The intake dam is built as a gravity dam in reinforced concrete with a channel for the grate and sliding hatch. It is adapted to the terrain on the site. The penstock, made of GRP/cast iron, is 0.9 metres in diameter and 900 metres long. It is entirely buried.

The 80 m2 power plant is constructed in the familiar Småkraft style, and in this case, with a prefabricated building on the ground. Outflow is led through pipes/channel back into the river.
