The main grid from Tonstad to Lysebotn will be upgraded from 300 kV to 420 kV, and work on new power lines will be conducted on three different power line sections:


  • From Ertsmyra substation in Sirdal municipality to Lyse substation in Lysebotn in Forsand municipality. 
  • Between Ertsmyra and Solhom substations in Kvinesdal municipality.
  • On the section between Lyse and Duge substations in Forsand municipality.


About 90 kilometres of the old grid between Tonstad and Lyse will be demolished once the new grid has been built. New substation facilities will also be constructed in Lysebotn and by Solhom power station in Kvinesdal; Lyse substation and Fjotland substation, respectively. 


“Continuation of the projects is of great significance for future operation and security of supply in South-Western Norway. The work will strengthen the main grid and facilitate new power production as well as the new international interconnections that we are building in the region,” says Executive Vice President Elisabeth Vardheim.


The power lines and substations that are ready for construction now, are included in the Western Corridor project, which involves a major upgrade of the continuous main grid between Sauda and Kristiansand. Start-up of construction is contingent on the necessary licences.


The Western Corridor project will bring major socio-economic benefit through establishment of new international interconnectors, and by facilitating connection of new renewable power production. The estimated cost of the Western Corridor project is between NOK 7.1 and 8.5 billion.
