RWE will work with Welsh port operators on developing infrastructure to support a “gigawatt-scale” floating wind build-out in the Celtic Sea off western Britain, the utility group announced.

The Germany-based global power giant has signed memoranda of understanding (MoUs) with Associated British Ports (ABP) and the Port of Milford Haven over potential manufacture and assembly of floating turbines and foundations, plus O&M support for completed wind farms at Port Talbot and Pembroke Dock.

RWE said it aims to build large-scale floating wind off Wales after entering the UK Crown Estate’s planned Celtic Sea round for seabed leasing, which could see acreage for up to 4GW of capacity awarded by the end of 2023.
