Mydalen is a power plant on the Skien River in Hjartdal Municipality in Telemark County.
Ownership: Statkraft is an indirect co-owner through its 66.62 per cent ownership in Skagerak Energi AS
Production: 29 GWh
Power: 7 MW
The power plant was commissioned in 1959 and uses a height of fall between Lake Kovvatn and Lake Breivatn.
Mydalen differs somewhat from most other power plants in that you cannot see water downstream from the plant. Water used in production continues by pipe to Lake Breivatn without seeing the light of day. So Mydalen power plant looks like any other kind of building.
The height of fall is 122 metres.
The plant is equipped with a Francis turbine and is operated jointly with Hjartdøla power plant.
Through its majority ownership in Skagerak Energi AS, Statkraft is co-owner of this power plant. Skagerak Kraft AS, a wholly owned subsidiary of Skagerak Energi, is responsible for daily operations, and manages the licences and obligations in terms of river management and regulating of the watercourse.
