Norwegian petrol company Equinor , together with its partners in the Troll and Oseberg fields, has started a study to identify possibilities for a 1GW floating offshore wind farm in Norway.

Equinor’s partners TotalEnergies , Shell and ConocoPhillips intend to develop the Trollvind floating offshore facility in the Troll area, which is located around 65km west of Bergen.

With an installed capacity of around 1GW and 4.3TWh of annual production capacity, Trollvind could supply clean energy to the Troll and Oseberg offshore fields via an onshore connection point.

In addition to providing green electricity to oil and gas installations, the wind farm could expedite offshore wind development in Norway while delivering additional power to the Bergen region.

Equinor chief executive Anders Opedal said: “Trollvind is a concept where renewable energy works to facilitate several objectives; helping cut emissions through electrification, delivering power to an area where shortages have already created challenges for new industrial development, and Norway maintains its position as a leader in the industrialisation of floating offshore wind.

“A full-scale floating offshore wind farm like Trollvind could boost momentum towards realising the Norwegian authorities’ ambition to position Norway as an offshore wind nation, building on expertise from the oil and gas industry.”

The partnership intends to purchase a significant amount of clean energy generated by the Trollvind wind farm at a price to make the project possible.

It is estimated that the offshore wind facility could deliver power for less than Nkr1 ($0.10) for each kWh. It is expected to come online in 2027.

TotalEnergies Country chair and managing director Phil Cunningham said: “We are excited about the possibilities to supply our energy production offshore with new renewable power.

“This project confirms Norway’s leadership in green energy production and our experience that working together is a value enabler.”
