Statnett is planning to upgrade the operating voltage on the 300 kV Aurland – Sogndal power line to 420 kV. The project is scheduled for completion by 2019.

Upgrading the power line to 420 kV will improve the transmission capacity across Sognefjorden and connect the 420 kV grid in Aurland to the new Ørskog-Sogndal power line which is currently under construction. The Aurland-Sogndal section is currently considered the main bottleneck in the Indre Sogn grid.

The upgrade will also enable Statnett to remove the existing facilities in Fardal.  In this connection, the Sogndal – Hove power line will also be re-routed from the Sogndal substation across Sogndalsfjorden.
