Grid upgrades in Southwestern Norway

Statnett is in the process of building its next-generation main grid. An important step towards the next-generation main grid is to increase the grid voltage from 300 to 420 kV (voltage upgrade). This will be done by converting existing lines and 300 kilovolt substations, and by replacing some old and weak lines with new ones. In this way we can increase the capacity of each line, without using new routes. This will contribute to the production of more renrewable energy.

The project has now entered the planning phase. The following is important in this phase:

  • Identification of needs
  • Concept choice studies
  • External quality assurance

Statnett is responsible for planning and applying for the projects we believe to be socio-economically viable.

Licensing process

The project has now entered the licensing phase. A regular licensing process is currently structured as follows:

Planning proposal:

  • Statnett submits a planning proposal to the Norwegian Water Resources and Energy Directorate (NVE)
  • The NVE submits the proposal for public consultation

Licence application:

  • Statnett submits the application with enclosed impact assessments to the NVE
  • The NVE will organise the consultation, site inspection and public meetings
  • The NVE submits its recommendation to the Ministry of Petroleum and Energy (MPE)
  • The MPE submits the recommendation for consultation and makes a decision
  • The King in Council makes the final resolution

Appeals process:

  • Potential appeals from affected parties
  • The NVE considers the appeals and submits it to the MPE
  • The MPE settles the appeal

Ongoing construction.
