The Gwynt Glas offshore wind project has today announced a significant strengthening of its joint venture with Sumitomo Corporation joining as an equal partner alongside EDF power solutions UK and Ireland and ESB. Each partner now holds a 33.33% stake, while DP Energy continues to provide critical development support, leveraging its expertise in early stage project delivery and local engagement.
This strategic collaboration brings together three global leaders in renewable energy combining deep expertise in large scale development and delivery. The partnership positions Gwynt Glas to advance confidently through its next phases, reinforcing its role in delivering clean, homegrown energy for Wales and the UK while supporting energy security and economic growth.
Gwynt Glas is a proposed innovative floating offshore wind farm in the Celtic Sea. The up to 1.5GW project continues to make strong progress and successfully submitted its Scoping Report to the Planning Inspectorate this summer.
Matthieu Hue, CEO of EDF power solutions UK and Ireland said:
"We are delighted to welcome Sumitomo Corporation to the Gwynt Glas team. Their extensive global experience in offshore wind development and investment complements our own and ESB’s, creating a powerful partnership dedicated to delivering this vital project for Wales and the UK.”

Jun Minase, General Manager, Overseas Energy Solutions SBU at Sumitomo Corporation:
"We are delighted to join the Gwynt Glas project. As a large-scale floating offshore wind development being advanced by EDF power solutions UK and Ireland and ESB, the Project represents an important opportunity to contribute to the energy transition. Leveraging our experience and expertise in both the UK market and the offshore wind sector, Sumitomo Corporation will work closely with its partners to support the successful development of the Project and enhance its long-term value.
