Project overview: The Ivar Aasen electrification is part of the Utsira High “power from shore” area solution that supplies onshore electricity via subsea transmission cables to offshore installations in the northern North Sea. It is distinct from the Ivar Aasen hydrocarbon field itself and refers specifically to the domestic shore-power...

Project Timeline (15)
28 Mar 2023Cable Installation Complete
Power cable installation to electrify the Ivar Aasen platform from shore was completed in March 2023, when NKT finalized the AC cable systems connecting multiple Utsira High platforms, including Edvard Grieg and Ivar Aasen, to the Johan Sverdrup-based onshore power supply, thereby enabling delivery of electricity from shore to Ivar Aasen.
Mar 2023Cable Installation Complete
In March 2023, NKT completed the power cable systems and AC cable connections that link the Johan Sverdrup hub to the Ivar Aasen platform, as part of the Utsira High electrification scheme, thereby finalising the cable infrastructure needed to supply Ivar Aasen with electrical power from shore via the Norwegian onshore grid.
Dec 2022Commercial Operations Full Power
The Ivar Aasen electrification project reached full commercial operation in December 2022, when the Utsira High area power-from-shore solution was established and the platform became fully electrified. From this point, Ivar Aasen, previously powered via cable from the Edvard Grieg installation, began receiving power from shore through the Johan Sverdrup area solution, covering its entire power demand with shore-based electricity.
Q4 2022First Power
By the fourth quarter of 2022, electrification of the Ivar Aasen and Edvard Grieg platforms had been finalised, with Ivar Aasen now receiving electrical power from shore through the Johan Sverdrup–Utsira High area solution, and contractor NKT confirming completion of the power cable systems connecting six Utsira High platforms, including Ivar Aasen, to the onshore grid.
28 Oct 2019Late Development Other
In October 2019 the Johan Sverdrup licence and the partners in the Gina Krog, Ivar Aasen, Edvard Grieg and Sleipner fields reached an agreement on the allocation of shore-based power within the Utsira High area solution. This agreement, implemented as part of Johan Sverdrup phase 2, confirmed that Ivar Aasen would receive power from shore via the shared Utsira High electrification system, marking a key late‑stage development milestone for the Ivar Aasen electrification project.
1 Sept 2019Onshore Construction StartStale
Onshore construction for phase 2 of the Haugsneset power-from-shore plant, which will help supply electricity from land to Johan Sverdrup and establish the area solution for power from shore to the Utsira formation fields including Ivar Aasen, was planned to start at Haugsneset after the summer of 2019, involving around 120 Aibel employees in the construction phase. This follows Equinor’s award of the contract to Aibel to build phase 2 of the onshore power plant east of Kårstø, which is intended to provide the shared shore power solution for Edvard Grieg, Ivar Aasen and Gina Krog.
11 Jul 2019Cable Supplier Selected
Lundin Norway awarded NKT a turnkey contract to supply and install a 24‑km, 132 kV AC high‑voltage power cable linking the Edvard Grieg production platform to the Johan Sverdrup field centre. This cable connection is described as completing the Utsira High Power Hub Project, which will use the Johan Sverdrup onshore power link to electrify multiple fields on the Utsira High, including Ivar Aasen, and thus constitutes the main offshore cable supply selection that enables the Ivar Aasen electrification scheme.
May 2019Planning Consent Awarded
Licence: Approval of Johan Sverdrup Phase 2 development including Utsira High power-from-shore area solution (covering Edvard Grieg, Gina Krog and Ivar Aasen)
In May 2019, Norwegian authorities approved the Johan Sverdrup Phase 2 development, which, in addition to a new processing platform and satellite areas, includes the power-from-shore supply to the Utsira High area. This approval authorises extending the shore-based electrical supply from Johan Sverdrup to the Edvard Grieg, Gina Krog and Ivar Aasen fields, enabling the Ivar Aasen electrification as part of the Utsira High area solution.
9 Oct 2018Onss Commissioned
The onshore HVDC converter station at Haugsneset near Kårstø, built by Aibel with HVDC equipment supplied by ABB and export cables installed by NKT, was officially brought into operation to supply the Johan Sverdrup field with power from shore. This commissioning of the land-based power-from-shore facility, connected by a 200 km cable to the offshore field centre, established the core infrastructure that will also be used to electrify other Utsira High fields including Ivar Aasen.
May 2018Cable Installation Start
In May 2018, Statoil started installation of the power-from-shore cable system for the Johan Sverdrup development, with the cable-laying vessel NKT Victoria beginning to lay nearly 200 kilometers of power cables from the converter station at Haugsneset near Kårstø out to the field in the North Sea. This cable infrastructure, which is described as the future lifeline of Johan Sverdrup, will in its second development phase enable power from shore to be extended to other Utsira High fields including Ivar Aasen, thereby underpinning the Ivar Aasen electrification project.
