Statnett is currently working to construct the next-generation national power grid. An important step towards this goal is to increase the capacity of the power line grid and the power stations by upgrading from today’s 300 kilovolts to 420 kilovolts.

This voltage upgrade will increase the capacity in the power line grid and, in turn, help improve security of supply and secure interconnectors to Europe. It will also facilitate production of additional renewable energy, which will help Norway and Europe achieve their climate targets.

What’s happening at Ertsmyra

  • Construction of a new 420 kilovolt substation at Ertsmyra, which will partly replace the existing substation at Tonstad.
  • NordLink: Establishment of a HVDC installation for the exchange of electric power between Norway and Germany. Overall development managed by NordLink.
  • Agder Energi: Establishment of a regional grid installation (132 kilovolts)
  • Re-routing of cables to the new Ertsmyra substation
