RWE has taken the financial investment decision on the 1.4 GW Sofia offshore wind farm project in the UK.

The 100 per cent RWE-owned project represents a total investment of approximately GBP 3 billion (EUR 3.48 billion).

The company is now poised to forge ahead with the construction of Sofia, with onshore enabling works due to start this Spring and offshore construction in 2023.

Final project completion is expected by the fourth quarter of 2026. RWE was awarded a Contract for Difference (CfD) for Sofia in 2019, achieving a strike price of GBP 39.65 per megawatt hour (in 2012 prices).

”Through this decision, we strengthen our commitment to growing and investing in renewable energy in the UK, and to playing a significant part in helping deliver the UK’s ambition to grow offshore wind capacity to 40 gigawatts by 2030,” Tom Glover, Chief Commercial Officer RWE Renewables and RWE UK Country Chair said.

”Today’s milestone and the achievements to come represent successful collaboration with the local, regional and national supply chain, and the local communities with whom we are committed to continuing to work. Through our investment, Sofia presents a great opportunity for RWE to unlock long-term local jobs, and business benefits, while delivering new renewable energy for over 1.2 million UK homes every year.”

The consented project is located on Dogger Bank, 195 kilometres from the nearest point on the UK’s North East coast.

The wind farm will have a single offshore converter platform, with the electricity generated transported via a high voltage direct current export cable to landfall 220 kilometres away in Redcar, Teesside.

Sofia will require a new onshore converter station, and already has an agreed grid connection point at the existing National Grid substation in Lackenby, Teesside, seven kilometres inland. RWE is reviewing port options for the project’s long-term operations & maintenance activity.

Preferred Supplier Agreements are already in place for all of Sofia’s key suppliers and RWE will now proceed to finalise contracts with them in the coming weeks.

Siemens Gamesa Renewable Energy is lined up to supply 100 of its SG 14-222 DD wind turbines.
