Project
The loan supports two grid investment projects in Norway: the upgrade of the Surna–Viklandet transmission line in Møre og Romsdal and the modernisation of the Frogner substation in Lillestrøm.
Statnett is upgrading the 47 km Surna–Viklandet transmission line from 300 kV to 420 kV, largely along the existing route southwest of Trondheim. The project aims to increase regional grid capacity and enable higher north–south power flows. Construction started in 2024 and is scheduled for completion in 2027. The project is classified as Category A and was disclosed for public consultation between 16 December 2025 and 16 January 2026, during which no comments were received.
Statnett is also upgrading the Frogner substation, originally built in 1973, to meet expected growth in electricity demand north of Oslo and to ensure reliable supply in support of electrification and the energy transition. Construction began in 2023 and is expected to be completed in 2029.
Fulfilment of NIB's mandate
Productivity:
The Surna–Viklandet project will significantly strengthen transmission capacity through central Norway and improve transfer capability towards western and southern parts of the country. The additional capacity is required to accommodate expected growth in electricity demand and to enable the connection of planned renewable generation. By reducing transmission constraints, the project supports more efficient utilisation of the Norwegian power system.
The Frogner substation is an important node in the transmission network supplying the Oslo and Romerike region. The upgrade will enable the substation to manage higher load levels and increased system complexity. Modernised switchgear and transformer capacity will support reliable operation, limit transmission losses, and maintain security of supply in one of Norway’s major consumption areas.
Environment:
The Surna–Viklandet 420 kV upgrade will strengthen regional transmission capacity and provide bidirectional supply to nearby substations, increasing exchange capacity with the regional grid and enabling higher north–south power flows. While new or expanded electricity generation is planned in the area, the project’s direct impact on additional production has not been quantified.
The Frogner substation upgrade focuses on modernising ageing infrastructure to ensure reliable electricity supply and accommodate future demand growth in the Oslo and Romerike region.
