Sumitomo takes 33.3% stake in UK’s Gwynt Glas floating wind project
The acquisition marks Sumitomo’s first foray into floating wind technology and aligns with its strategic pivot toward overseas energy solutions under its 2026 management plan.
Sumitomo Corporation has acquired a 33.3 per cent equity stake in the Gwynt Glas floating offshore wind farm project, located in the Celtic Sea approximately 40km from the UK coast. The development, which is being led by EDF Power Solutions UK and Ireland and the Electricity Supply Board (ESB), is planned to have a generation capacity of up to 1.5GW.
This transaction represents Sumitomo’s first investment in a floating offshore wind project. While the company has participated in European offshore wind initiatives since 2014, the move into floating technology distinguishes this asset from its previous holdings. Floating platforms allow for the exploitation of wind resources in deeper waters, a capability the UK government has identified as critical to meeting its Net Zero 2050 target.
The investment follows a memorandum of understanding signed in 2025 with the UK’s Office for Investment, under the Department for Business, Innovation, Science and Trade, to promote inward investment. The Gwynt Glas project is cited as one of the key initiatives under this agreement, reflecting Sumitomo’s broader strategic realignment.
In May 2024, Sumitomo announced its Medium-Term Management Plan 2026, which aims to accelerate portfolio transformation and expand its overseas energy solutions. The company stated it intends to develop renewable energy projects in line with local energy policies and market conditions, seeking to support sustainable growth and contribute to clean energy efforts in the UK and other regions.
Jun Minase, general manager of Sumitomo Overseas Energy Solutions, described the project as an important opportunity to contribute to the energy transition. He noted that the company would leverage its experience in the UK market and the offshore wind sector to work closely with partners and enhance the project’s long-term value.
The acquisition contrasts with Sumitomo’s recent divestment of equity stakes in three offshore wind power projects off the Belgian coast. This sale was part of a wider strategy to reallocate resources, suggesting a selective approach to its global renewable energy portfolio as it prioritises specific technological segments and geographic markets.
The specific timeline for the construction and operational commencement of the Gwynt Glas project has not been disclosed, nor has the financial value of the 33.3 per cent stake. The original report was created and published by Power Technology, a GlobalData owned brand.
