Skanska has signed a contract with Hydro for the construction of the new Illvatn pumped-storage hydropower plant in Luster municipality, Vestland County, Norway. The contract is worth NOK 950M, about SEK 900M, which will be included in the Nordic order bookings for the fourth quarter of 2025.
The contract includes construction of an underground power station with associated tunnel and infrastructure work. A pressure tunnel of approximately 8 kilometers will be constructed between the Fivlemyrane and Illvatn reservoirs, with the total tunnel system measuring around 9 kilometers. The project also includes construction of a new permanent road, access tunnel to the transformer hall and station hall, as well as a surge system measuring 250 meters in length. Parts of the project area are roadless and require helicopter transport.
The Illvatn pumped-storage plant will utilize the energy potential between the Fivlemyrane and Illvatn reservoirs. The facility will increase the storage capacity in Illvatn by 90 million cubic meters and contribute to more efficient utilization of water resources by pumping water up to Illvatn during the summer months or when energy prices are low. The new power plant will provide new annual electricity production of approximately 84 GWh.
Preparatory work has already commenced, and the project is scheduled for completion in august 2030.
