Development plans for Troll West electrification handed over to the authorities
Equinor and partners have submitted the PDO for electrification of Troll platforms in the North Sea.
How we’re contributing to reductions in global emissions:
Electrification of oil and gas operations
Electrification means replacing a fossil-based power supply with renewable energy, enabling a reduction in greenhouse gas emissions. Equinor is fully committed to reducing emissions from our offshore oil & gas production. Here’s how we’re doing it.
0
planned reduction in emissions from Norwegian Continental Shelf by 2040
0
emissions from our oil & gas production on the NCS by 2050
0
reduction in Norway’s total emissions by 2030
Hilde Røed, Senior vice president climate and sustainability
“We’ve addressed our own emissions. And we’ve come up with a concrete and feasible plan. Put simply: we’re thinking globally, and acting locally. We hope many others will follow suit.”
Hilde Røed, Senior vice president climate and sustainability
WHAT IS ELECTRIFICATION?
- Electrification is using electricity as the power source at offshore platforms, instead of or in addition to gas, on order to reduce emissions.
- The electricity is provided either through power cables from land, or by offshore wind turbines.
- Electrification in the North Sea is one of the main measures to reach our climate ambitions for the next decades.
WHAT ARE THE CLIMATE BENEFITS?
- Efficiency improvements by replacing offshore gas turbines with electricity, allowing the gas to be used elsewhere with greater efficiency and thereby reduced emissions. As market demand for hydrogen increases, natural gas can be converted to hydrogen, decarbonising products and production from the NCS.
- The reduction in Norwegian emission sources will mean that there will be fewer emission quotas. When emission sources are reduced, allowances become redundant and EU quotas are revoked. Electrification thereby contributes to reducing emissions in the European energy system.

The transition to a low-carbon society requires strong growth in renewable energy. However, even in the most optimistic forecast scenarios for the green shift, the world will still be dependent on oil and gas for a long time to come. It is therefore essential that the oil and gas that the world needs is produced with as low a carbon footprint as possible.
Today, most offshore installations produce their own electricity using gas turbines, which account for a quarter of Norway's total emissions of both NOX and CO2.
Electrification of the shelf involves laying cables from the mainland to the areas where it will be most appropriate to replace the gas turbines.
Power from either renewable energy production or gas power plants with CO2 management can replace parts of today's polluting power generation on the oil platforms. Here, we explain the many initiatives we are undertaking in electrification.
“Cutting greenhouse gas emissions on the Norwegian shelf is important. The UN Climate Panel has designated electrification and energy efficiency as important climate measures. In addition, measures taken early are extra important, because they result in lower cumulative emissions.”

Facts and figures about electrification of the Norwegian continental shelf
- Oil and gas installations on the NCS emit approximately 13 million tonnes of CO2 equivalents
- Over 160 gas turbines used for power generation on the platforms as well as flaring account for 84.6% of total CO2 emissions from the Norwegian continental shelf
- In 2018, petroleum activities on the Norwegian continental shelf accounted for 28% of Norway's total greenhouse gas emissions
- Operators on the Norwegian continental shelf pay tax on emissions. In addition to climate quotas, which are around NOK 250 per tonne, operators must also pay a separate fee of approx. 500 kroner per tonne. This means that in practice it costs about NOK 750 for every tonne of emissions
- Electrification is an investment in both the climate and the sustainable future of the oil industry
- Electrification of the Norwegian continental shelf is an expensive but profitable climate measure
- Our Johan Sverdrup field has CO2 emissions of just 0.67 kg per barrel, compared with an average of 9 kg, thanks to electrification.

The oil and gas industry is largely run on electricity generated on site using gas turbines and currently accounts for approximately one quarter of Norway’s total carbon emissions.
Troll A was the first platform on the Norwegian continental shelf to be electrified, back in 1996.
The Gjøa field was electrified from the very outset. As development operator, Equinor lay a 100 km long cable from Mongstad out to the Gjøa field – the longest alternating current cable in the world at that time.
In 2018, Martin Linge was prepared for electrification through the laying of a 163 km long cable from Kollsnes. Production from the Martin Linge field is scheduled to start in 2021.
The Johan Sverdrup field has been electrified by means of power from land, helping ensure record-low emissions from production. Johan Sverdrup has CO2 emissions of just 0.67 kg per barrel, compared with an average of some 9 kg on the Norwegian continental shelf and 18 kg globally.
Sverdrup phase 2 will also supply other fields on the Utsira High with power from the shore. Plans are also being made to enable the Sleipner Field Centre, the Gudrun platform and other connected fields to reduce their emissions through power supply from the Utsira High.
The next technological milestone will be to supply the Gullfaks and Snorre platforms with wind power through the pioneering project Hywind Tampen, the largest floating offshore wind farm in the world when it starts operating in 2022.
In addition, there is work underway to investigate the possibility of supplying power from shore to the Troll B and C platforms and to the Oseberg field. We are also exploring the possibility of supplying the LNG plant in Hammerfest with power from the grid. Further projects will come in the years ahead.
