The two cables going from Sogn and Ulven substations is from the 1950s and 60s, and needs to be replaced. Sogn substation needs upgrading on order to withstand a future voltage of 420 kV.
Statnett will thoroughly explore potential solutions for the cable interconnectors between Sogn and Ulven. We will map buildings, infrastructure, roads and the environment, assess emergency preparedness, risk for the surrounding areas and make economic calculations. Throughout the process, we will have meetings with local authorities and public agencies to receive their input.
