About Sofia Offshore Wind Farm

Key facts and figures about one of the world’s largest offshore wind farms

ABOUT SOFIA

Sofia will be one of the largest offshore wind farms in the world as well as one of the farthest from shore. Technically it will be a major engineering feat, drawing on long-term offshore wind heritage and on our suppliers’ technological expertise. It will implement many of the innovations and advances made by the offshore wind sector as it has grown in size and sophistication over the past few years.

KEY BENEFITS

OWNER

Sofia Offshore Wind Farm is currently 100% owned by RWE. In line with the company’s strategy for offshore wind, it is likely investment partners will be sought when the project is sufficiently matured.

THE STORY SO FAR

2009

In 2009, RWE joined forces with three other leading international energy companies - SSE, Statoil (now Equinor) and Statkraft - to bid for a Zone Development Agreement as part of The Crown Estate’s third licence round for UK offshore wind farms (Round 3).

January 2010

In January 2010, following a competitive tender process, The Crown Estate announced that Forewind had been awarded development rights for the largest zone: Dogger Bank.

2015

In 2015 the Secretary of State awarded development consent orders to four projects, each with a proposed installed capacity of 1.2GW. These were Dogger Bank Creyke Beck A, Dogger Bank Creyke Beck B, Dogger Bank Teesside A and Dogger Bank Teesside B.

March 2017

In early (March) 2017, Statkraft decided to leave Forewind. SSE and Equinor took the opportunity to increase their shares to 37.5% each, with RWE (innogy) retaining a 25% share.

August 2017

In August 2017, the remaining three Forewind partners agreed on how best to further progress the development of the four consented projects, with RWE taking full ownership and control of Dogger Bank Teesside B. SSE and Equinor together progress the other three projects.

December 2017

Dogger Bank Teesside B was re-named Sofia via an internal competition and in December 2017, the new name Sofia Offshore Wind Farm was registered at Companies House.

2019

The year 2019 saw two major successes: when an application to increase the installed capacity to 1.4GW was approved and when the project won a Contract for Difference in the UK Government's competitive auction round, greenlighting the team to progress the project.
