Statnett SF is owned by the Norwegian State and organized pursuant to the Act relating to state-owned enterprises. The ministry of Petroleum and Energy represents the State as owner.

The intention of this agreement is to cover the costs incurred by the owners of the national grid for developing and maintaining the grid. Oslo, October 2013 Statnetts mission is to: Ensure quality of supply in the short term by coordinating electricity supply and demand Ensure quality of supply in the long term by developing the Norwegian national grid Offer access to the power transmission grid on equal terms to all by administering the Main Grid Commercial Agreement Gunnar G. Løvås Ensure accessible transmission routes by means of good maintenance practices.
