Fields with power to shore
Overview of fields with power from shore
In 2020, a total of 16 fields were either operated entirely or partially using power from shore, or where decisions were made and development was under way to implement power from shore solutions. I 2025 er dette antallet økt til 39.
In 2020, facilities on the Troll, Gjøa, Ormen Lange, Valhall, Goliat and Johan Sverdrup fields were supplied with power from shore in whole or in part. Several fields were also tied back to these facilities, and they were therefore also receiving power from shore. Power from shore was under development on the Martin Linge, Edvard Grieg, Ivar Aasen and Gina Krog fields. This means that there was a total of 16 fields either running on power from shore or where power from shore was under development. All of them are now in operation.
Following the 2020 report, full or partial transition to power from shore was decided for the Troll B and C, Oseberg Field Centre and Oseberg Sør, Sleipner, Njord and Draugen facilities, as well as at the Hammerfest LNG onshore facility (Melkøya). Decisions have also been made to develop the fields in the Yggdrasil area with power from shore.
Tables 2, 3 and 4 provide an overview of fields with power from shore that are currently in operation, and fields where power from shore is under development. The tables also show associated fields where processing takes place on the host facility, and which are then operated using power from shore via this facility. When all projects under development are operational, there will be a total of 39 fields with power from shore.
Table 1 (below): Fields and facilities in operation with power from shore. Here, associated fields means subsea developments or simpler facilities such as wellhead platforms tied back to a host facility for processing and power supply. For these fields, the power solution is a result of choices made on the facility.

Associated fields |
|
Troll A |
Troll A was the first facility to receive power from shore. Since the facility first came on stream in 1996, all of its power needs have been covered with electricity from Kollsnes. The volume of transmitted electricity has increased in multiple phases to compensate for falling reservoir pressure. |
|
|
Gjøa |
Parts of Gjøa's power needs are covered with power from shore. The gas export is run by a local gas turbine. With the aid of a heat recovery unit, this turbine also supplies necessary process heat. The field has been partially electrified since its start-up in 2010. |
The Vega, Nova and Duva fields are subsea fields operated with power from Gjøa. |
|
Ormen Lange/Nyhamna |
Ormen Lange is a subsea development with a pipeline to an onshore process plant (Nyhamna). The entire power need for the onshore plant and subsea facilities is supplied from the onshore grid. Ormen Lange came on stream in 2007. |
|
|
Valhall |
As part of a larger redevelopment on the field, a power from shore solution became operational in 2012. This is the first field to be refit from operation with gas turbines to operation with power from shore. The entire power need is covered from shore. |
The Hod field consists of a wellhead platform supplied with electricity from Valhall. The Fenris field is under development with an equivalent solution. |
|
Goliat |
Since its start-up in 2016, Goliat's entire power need has been covered with power from shore. Electric boilers cover the need for process heat. The facility also has a gas turbine with a heat recovery unit that has the capacity to cover the entire power need if this should be necessary. |
|
|
Johan Sverdrup |
This field was developed in two phases. When the first phase started up in 2019, power from shore was already in place. In connection with approving the development plan for phase 2, a decision was made to establish an area solution for power from shore. The area solution would cover the Edvard Grieg, Ivar Aasen and Gina Krog fields. It was also designed for possible increased needs on the associated fields, as well as any future third-party tie-backs. Johan Sverdrup phase 2 started up in late 2022. The entire power need is covered with power from shore. |
|
|
Martin Linge |
This field was developed with power transmitted via a cable from Kollsnes. The field was connected to power from shore in November 2018 and started producing oil and gas in 2021. The entire power need is covered with power from shore. |
|
|
Edvard Grieg |
This field, which came on stream in 2015, has been running on power transmitted via Johan Sverdrup and the area solution on the Utsira High since 2022. The entire power need is covered with power from shore. |
Solveig is a subsea field with power supplied via Edvard Grieg. |
| Gina Krog | This field, which came on stream in 2018, has been running on power transmitted via Johan Sverdrup and the area solution on the Utsira High since 2023. The entire power need is covered with power from shore. | Eirin is a subsea field under development which will receive power via Gina Krog. |
| Ivar Aasen | Since the field came on stream, Ivar Aasen's entire power need has been covered via a power cable from Edvard Grieg. Since the area solution on the Utsira High became operational in 2022, Ivar Aasen has also been running on power from shore. | Hanz and Symra are two subsea fields tied back to Ivar Aasen. Symra is under development. |
| Sleipner |
The development plan for transitioning Sleipner to partial operation with power from shore was approved in 2021. A decision was made to connect Sleipner to the area solution on the Utsira High with a power cable via Gina Krog to Sleipner A. The premise was that Sleipner would receive any available power once other fields' consumption was covered, while some power would still be generated by gas turbines. Since the power transmission solution became operational in 2024, Sleipner has received more electricity than what was originally presumed. The licensees are considering whether to use additional available electricity from the Utsira High to electrify additional equipment. |
The other fields tied back to Sleipner are Sigyn and Utgard, which are subsea fields, and Gungne, which was drilled with three wells from the Sleipner A facility. |
| Gudrun | Since Gudrun started up in 2014, it has been running on power transmitted via a cable from Sleipner A. Since power transmission from the Utsira High to Sleipner became operational in 2024, Gudrun has also been operated with power from shore. |

Troll B and C |
The development plan for transitioning to power from shore for Troll B and C was approved in 2021. The decision involved partially electrifying Troll B and fully electrifying Troll C. Partial electrification of B and C became operational in 2024, and work is under way on full electrification of C. The power station at Kollsnes and the subsea cable were built with the capacity to potentially fully electrify Troll B at a later date. The licensees decided to cancel work on this project in 2024. |
The Fram, Fram H-Nord and Byrding fields are all subsea fields supplied with power from Troll C. |
|
Oseberg and Oseberg Sør |
A refit of the Oseberg Field Centre and Oseberg Sør to partial operation with power from shore was approved in 2022. This project is under development. The power station at Kollsnes and the subsea cable are prepared for additional electrification. In the summer of 2024, the licensees decided to suspend work on additional electrification of the Oseberg Field Centre. |
Tune is a subsea field that receives power from the Oseberg Field Centre. |
|
Draugen |
Njord's refit to power from shore is a coordinated development with Draugen, approved in 2023, where a cable is laid from shore to Draugen and further on to Njord. Draugen will be fully electrified after the refit. When major motor loads are started up, such as gas compressors and loading pumps, a gas turbine is started up to provide the necessary extra power to start the motors. |
|
|
Njord |
Njord's refit to power from shore is a coordinated development with Draugen, approved in 2023, where a cable is laid from shore to Draugen and further on to Njord. Njord will be partially electrified. The gas turbines, which are currently used to generate power for Njord A and B, will be replaced with power from shore. As before, gas export will be operated by a gas turbine. |
Bauge, Fenja and Hyme are subsea fields that receive power from Njord. |
|
Snøhvit/Melkøya |
Snøhvit is a subsea facility with a pipeline to the onshore facility on Melkøya, Hammerfest LNG. The onshore facility has primarily been operated with power generated by gas turbines and a heat recovery unit that covers the LNG plant's heating needs. The transition to full operation with power from the grid was approved in 2023. This project is under development. After the refit, the heating need will be covered by electric steam boilers. The total transmission capacity after the refit is considered to be sufficient to cover any future needs on Snøhvit, for example offshore compression. |

|
Yggdrasil |
Yggdrasil is the name of a coordinated development of the Hugin, Munin and Fulla fields in the central part of the North Sea. The area consists of multiple discoveries and a previously shut down field, and is under development. The area is being developed with power from shore to the Hugin A facility and further on via cable to Munin. The other facilities, consisting of a wellhead platform (Hugin B) and seabed templates, will have their power need covered from Hugin A and Munin. The total transmission capacity is considered to be sufficient to cover future power needs in the area. |
