Construction work at the end of a roadless road

The excavation work for the Lidal and Romøyr hydropower plants is in full swing in Western Norway.

Lemminkäinen and the Norwegian energy company Småkraft AS signed an agreement on the construction of two hydropower plants in Sogn and Fjordane county in Western Norway in July 2015. The excavation work on the Lidal and Romøyr power plants began the same month.

Our contract covers the construction of the two power plants, including intakes, shafts and tunnels. In addition, we will be building intakes for two other power plants as part of the Fjærland project, including approximately 2.5 kilometres of tunnel construction.

We have now excavated more than two kilometres of tunnels and 600 metres of shafts. The project involves approximately 40 employees in the field, with around ten more in the office. 

Project Manager Ola Kvammen confirms that the excavation of the tunnels has run smoothly and is nearing the final stages.

“We expect to complete the tunnel excavation work in early June. Drilling at the Romøyr pressure shaft will continue and construction work will also continue at the Lidal power plant,” he says.


The contract is part of the Fjærland project by Småkraft AS, in which the company will develop six small power plants along rivers discharging into Fjærland Fjord. The project is expected to be completed around the end of the year.

“The contract should be complete by mid-January 2017, and there is no reason to believe that we will not stick to the schedule,” says Kvammen, satisfied that everything has gone according to plan so far.

Naturally, there have been problems along the way. All of the power plants are located in an area inaccessible by road. However, Lemminkäinen has considerable and diverse experience in building power plants in challenging terrain.


“All transport has been carefully planned and coordinated,” says Kvammen.

Ships are being used for transport at sea level, but materials must be taken higher by helicopter. In the winter, Lemminkäinen also built an 18-kilometre mountain road through the snow.

“The road allowed us to ensure an ongoing, unbroken supply chain.”
