Stølsdal is a hydropower plant on the Ulla-Førre river system in Hjelmeland Municipality in Rogaland County. The power plant came online in 1986.
The power plant has an installed capacity of 17 MW as a power plant and 2x3 MW of installed pump capacity. The water can be pumped up into Kvilldal power plant's intake reservoir. The power plant exploits the elevation difference of 103 metres from lake Kvivatnet and lake Bjørndalsvatnet. Lake Vassbotnvatnet is used as a regulation reservoir for the pumping station. The lake can be regulated between 475 and 470 metres above sea level.
Statkraft's subsidiary Skagerak Energi also has a shareholding in Kvilldal power plant.
