Development plans for Troll Vest electrification handed over to the authorities

Total E&P Norge AS supports Troll Vest electrification, the plan for development and operation submitted 21 April 2021 to the Minister of Petroleum and Energy by the license partners.  

The decision includes partial electrification of the Troll B platform and full electrification of Troll C in the North Sea. This will cut CO2 emissions by almost half a million tons per year, which is the equivalent of more than three percent of the petroleum industry’s emissions on the Norwegian continental shelf (NCS) and one percent of the global CO2 emissions in Norway. NOx emissions from the field will be reduced by some 1,700 tons per year. Capital expenditures total about NOK 7.9 billion. The project has been pledged a total of NOK 520 million in financial support from the Norwegian NOx fund.  

“The financial support provided by the Norwegian NOx fund helps this project materialize as well as making the link between NOx-taxes paid by the industry and the industry´s projects to reduce emissions, encouraging the emergence of climate positive projects”, says Arild Jørgensen, Total E&P Norge AS´ Asset Director.  

The Troll field – a giant on the NCS 

The Troll field is a giant in the North Sea, and the most prolific field on the NCS. The field has delivered, and will long continue to generate, enormous values for the Norwegian society. Historical revenues since 1995 total about NOK 1,650 billion, most of which has gone to the Norwegian state. Oil production at Troll is in the tail end phase, whereas only half of the gas resources have been produced.   

“The purpose of our operations in Norway is to add value to Total and Norway´s shared energy future. Our participation in Troll and the Troll Vest electrification project are good examples of us pursuing that purpose”, says Phil Cunningham, Total E&P Norge AS´ Managing Director. 

“The electrification of Troll Vest is also in concert with our ambition to become the responsible energy major”, Cunningham continues. “We continuously integrate climate into our strategy as we develop our projects aiming to reach net zero emissions overall within 2050”.   

Development solution 

The subsea cable to the Troll B and C platforms will have a landfall at Kollsnes in Øygarden west of Bergen.  A high-voltage subsea cable will run from Kollsnes to Troll B, and one from Troll B to Troll C.  

Troll Vest electrification includes full electrification of Troll C, and partial electrification of Troll B. This means that both platforms’ current power demand will be met from shore. In addition, the two gas export compressors on Troll C currently driven by gas turbines will be replaced by electric motors. The infrastructure at Kollsnes and cable out to the platform will be designed for a possible future full electrification also of Troll B.    

The Troll A platform, which came on stream in 1996, was the first electrified installation on the NCS. 

According to plan Troll B will be partially electrified in the first quarter of 2024, and Troll C will be fully electrified by the second quarter of 2026. 

The Troll Unit partners are Equinor 30.6 % (operator), Petoro 56 %, Shell 8.1 %, Total 3.7 % and ConocoPhillips 1.6 %.
