The project for client Eidsiva Vannkraft involves about 12km of tunnelling work, construction of the power station and transformer hall in the mountain and concrete work around the intake, power plant area, outflow and portal.
Nedre Otta power plant will use the existing intake dam at the Eidefossen power plant. The water will travel through tunnel from the intake to the new plant. It will have an installed capacity of 85MW and the annual production from the plant will be about 315GWh, equivalent to the consumption of around 15,000 households.
The project is designed to ensure that rafting, canoeing and fishing will be able to continue as before in the area during summers.
Construction will begin next month for completion in spring 2020.
