Mødalen-Samnanger in operation
The reconstruction of the existing power line between Mødalen and Samnanger will help increase transmission capacity between the northern and southern regions of Western Norway, without increasing the number of pylons.
In connection with the construction of the power line between the Sima power plant and Samnanger substation, Statnett also rebuilt the existing power line between Mødalen and Samnanger. The new power line has been constructed for 420 kV voltage, whereas the old power line was for 300 kV. The project is part of a long-term project of upgrading the national main grid to 420 kV. The new section, which is about ten kilometres long, entered operation in June 2012. The section is part of the power line between Mauranger and Samnanger.
As the rest of the 300 kV grid is upgraded, more power can be transmitted between Western Norway's northern and southern regions, without increasing the number of pylons. Further upgrades can be conducted after the Sima-Samnanger power line has entered operation, ensuring that security of supply is acceptable when some sections are disconnected for reconstruction.
