 This project shows how to get a significant amount of power by utilized watercourses around existing exposed watercourses by utilizing water resources in a better way. We simply get more power out of each drop, says Kristin Lian, CEO of Hafslund Kraft.

The Hemsilvassdraget has already been influenced by previous hydropower developments through the development of the power of the Hemsil 1 and Hemsil 2. The new power plant will, like Hemsil 2, have intake at the Eikredammen in Hemsedal municipality. A new tunnel will be built in the mountains in parallel with an existing tunnel to Hemsil 2, and the power station will be located in the mountains in connection with the power station of Hemsil 2 on Gol. Hemsil 3 will have an outlet to the Hallingdalselva just off today's expiry of Hemsil 2.

The project will increase power generation in Hemsil 2 by approx. 110 GWh through an even better utilization of water resources than today. The installed effect will increase from 98 to 181 MW, which will improve the power plant's ability to produce power when the need is greatest.
