The Sleipner/Gudrun electrification project is an offshore HVAC power‑from‑shore link that supplies onshore renewable electricity to the Sleipner field centre and the Gudrun platform on Norway’s Utsira High. The physical link consists of a circa 28 km high‑voltage subsea AC cable between Sleipner and the Gina Krog platform, with Gina...

4 Apr 2024Financial Other
Upon start‑up of partial power‑from‑shore operations for the Sleipner field centre and Gudrun platform in March 2024, Equinor reported that total investments in the Sleipner/Gudrun electrification project amount to about NOK 1.08 billion. The figure includes the EPCIC modification work on Sleipner awarded to Aibel and the high‑voltage cable system manufactured and installed by NKT, as part of the Utsira High electrification scheme.

24 Mar 2024First Power
On 24 March 2024, Equinor started supplying the Sleipner field centre with electricity from shore via a 28 km power cable from the Gina Krog platform, itself connected to the Johan Sverdrup Utsira High area power-from-shore system, and on the same date the Gudrun platform was connected to this onshore power through its existing cable to Sleipner, marking the first import of shore power and the start of partial electrification for Sleipner and Gudrun. This milestone enables a significant reduction in emissions from the Sleipner/Gudrun area as gas turbines are gradually phased down and all Utsira High installations operate with power from shore.
24 Mar 2024Commercial Operations Full Power
On 24 March 2024, shore power supply to the Sleipner field centre via a cable from the Gina Krog platform entered operation, and on the same date the Gudrun platform began receiving electricity through the existing cable from Sleipner. This partial electrification of Sleipner, Gudrun and associated fields on the Utsira High marked the start of operational use of power from shore for the Sleipner/Gudrun electrification project, enabling significant CO₂ emissions reductions on the Norwegian continental shelf.

Licence: Approval of revised Plan for Development and Operation (PDO) for partial electrification of the Sleipner field centre
The Norwegian Ministry of Petroleum and Energy approved Equinor’s revised Plan for Development and Operation (PDO) for partial electrification of the Sleipner field centre, enabling the Sleipner/Gudrun power-from-shore connection via Gina Krog as part of the Utsira High area solution and supporting substantial CO₂ emissions reductions.
9 Jun 2020Capital Support Awarded
In connection with Equinor and its partners’ investment decision to electrify the Sleipner field centre and associated fields such as Gudrun via power from shore, Norway’s Business Sector NOx Fund committed to contribute up to NOK 430 million towards the project costs. This capital support helps realise the partial electrification scheme that links Sleipner and its tie‑ins into the Utsira High power‑from‑shore area solution.

9 Jun 2020Cable Supplier Selected
On 9 June 2020, Equinor and its partners confirmed that NKT had been awarded the contract to manufacture and lay the 28‑km high‑voltage power cable between the Gina Krog platform and the Sleipner field centre, providing the key subsea link that enables partial electrification of Sleipner and associated fields, including Gudrun, from the Utsira High power‑from‑shore system.
9 Jun 2020Planning Consent Submitted
Licence: Revised Plan for Development and Operation (PDO) for partial electrification of the Sleipner field centre and associated fields
Equinor and its partners Vår Energi, LOTOS and KUFPEC submitted a revised Plan for Development and Operation (PDO) for partial electrification of the Sleipner field centre to the Norwegian authorities, covering the new power-from-shore solution via Gina Krog that will also supply Gudrun and other tie-ins on the Utsira High.
Jun 2020Fid Financial Close
Equinor and partners Vår Energi, LOTOS and KUFPEC took the final investment decision in mid‑2020 to partly electrify the Sleipner field centre, enabling power‑from‑shore via a new 28 km high‑voltage cable from Gina Krog as part of the Utsira High area solution that will also supply the Gudrun platform and other tie‑in fields. The Sleipner power‑from‑shore investment was set at about NOK 850 million, supporting emission reductions of over 150,000 tonnes of CO₂ per year from Sleipner within the wider Utsira High electrification scheme.

Oct 2019Late Development Other
In October 2019, Equinor announced that the Utsira High area licence partners were working towards the partial electrification of the Sleipner field centre together with the Gudrun platform and other tie‑in fields, using an expanded power‑from‑shore solution expected to supply ten fields and reduce CO₂ emissions by about 1.2 million tonnes per year.
