Hylen power plant

Norway / Hydropower / Power plant

The Hylen power plant uses water from the Suldalslågen watercourse in Suldal Municipality in Rogaland County.

  • 1980
    Entered into operation
  • 160 MW
    Installed capacity
  • 653.3 GWh
    Annual production

The power plant was commissioned in 1981 and uses a height of fall of 68 metres from Lake Suldalsvatnet down to sea level at Hylsfjorden.

The water level of Lake Suldalsvatnet can be regulated within a range of 1.5 metres. Lake Suldalsvatnet receives water from Kvilldal power plant. A separate spillway has been built at Hylen power plant to ensure run-off in case of plant stoppages including during maintenance work. Two Francis turbines are installed in the plant.

Architect Egil Sorteberg designed and drew the plans for the machine room in Hylen power plant.

Hylen power plant is one of Statkraft's facilities being considered for preservation as a cultural heritage site. The reception building has therefore been proposed for preservation. In addition, several of the power plant's caverns inside the mountain are included in the conservation plan.

Statkraft's subsidiary Skagerak Energi has an ownership stake in Hylen power plant.

Good Environmental Choice (Bra Miljöval)

The power plant is certified for Bra Miljöval (Good Environmental Choice). The label is managed by Svenska Naturskyddsföreningen and is a Swedish ecolabel with strict criteria for environmental protection of power plant operations. The label ensures that the electricity is generated in a sustainable way, considering both the environment, flora and fauna around the power plant.
