A RWE spokesperson said: “The priority of the Five Estuaries project is to progress its transition from development into construction and ultimately operation.
“We are delighted that EDF, with its long-standing commitment to delivering UK renewables, is committed to maintaining the pace of the project’s ambitions, and we look forward to seeing it come to fruition in the months and years to come.”
The Five Estuaries Offshore Wind Farm, located in the southern North Sea, covers two seabed zones spanning approximately 128km².
The project has construction consent for up to 79 wind turbines, each with a maximum tip height of 370m, and associated foundations.
When fully operational, the wind farm is expected to have a total capacity sufficient to supply around one million average UK households.
Development consent for the project was granted on 17 December 2025 by the UK’s Secretary of State for Energy Security and Net Zero.
RWE will continue to support the transition process to EDF in the short term.
The Five Estuaries scheme is an extension project associated with the Galloper Wind Farm, which lies 30km off the Suffolk coast.
Galloper is a 353MW facility with a reported investment of $1.98bn (£1.5bn). It began generating power in November 2017 and became fully operational in March 2018.
The planned Five Estuaries extension will cover two seabed areas and connect onshore at Sandy Point, next to Frinton-on-Sea and Holland-on-Sea.
RWE secured five awards representing 6.9GW of installed capacity in the UK’s most recent Contracts for Difference Allocation Round 7 and intends to add a net 5GW of offshore wind capacity by 2031.
Last month, RWE reached a final investment decision to construct a battery storage facility with a capacity of 400MW/1.1GW-hours at its Moerdijk power station in Noord-Brabant, the Netherlands.
