A new floating wind industry for the Celtic Sea region

The creation of a floating wind industry for the Celtic Sea region presents a multi-billion pound economic development and investment opportunity, unlocking a prosperous green legacy and Net Zero future for the region.

RWE, as Wales’ premier renewable energy generator and second largest offshore wind operator globally, is preparing to develop, install and operate commercial scale floating wind projects within the Celtic Sea, if successful in The Crown Estate’s forthcoming seabed leasing round.

The UK has always been a core market for RWE, having been involved in UK offshore wind since the beginning, participating in the UK’s very first offshore wind demonstrator as well as developing the first commercial scale offshore wind farm at North Hoyle, which we continue to operate. In British waters, RWE’s fleet now includes ten projects in operation and a further twelve in construction or development. 

The Celtic Sea is the next frontier in this space, offering some of the best floating wind potential in the world, with all the requisite ingredients necessary to build the capability to deploy and maintain this new technology at scale in a way that will flourish well into the next century.

RWE’s vision for the Celtic Sea

The development of a new industry for floating wind in the Celtic Sea region will make a significant contribution to unlocking our net zero future, spearheading a multi-billion pound economic opportunity that will boost the prosperity of the region through green industrialisation, creating a lasting legacy of innovation, manufacturing and operations, with a newly-skilled workforce, bringing a host of benefits directly into the fabric of local communities.

Through early action, bringing forward the opportunity of floating wind deployment as well as the significant upfront investment needed to attract incoming supply chain opportunities, the UK can become a global leader of this emerging industry.

Together with our more than 125 year strong asset base and hundreds of experienced staff in Wales, the benefits brought by a new floating wind industry will be combined with our net zero and innovation strategies for the region that will reap collective synergistic benefits.

Our plans to decarbonise our 2.2GW Pembroke Power Station and create a centre for green technology, Pembroke Net Zero Centre, that includes creation and use of green hydrogen, are collective benefits that will be accelerated from the advancement of RWE floating wind projects within the Celtic Sea.

Development through Partnerships

In order to develop robust plans unlocking the unique benefits which floating wind can bring to the region, RWE is already working in partnership with some of the largest, local industrial leaders. Just some of our local and global partnerships of relevance to the Celtic Sea floating wind opportunity are listed below:

In early 2022, we detailed our intention to work with ABP Port Talbot and the Port of Milford Haven, to develop plans for new port infrastructure at Port Talbot and Pembroke Dock which would support a pipeline of floating offshore wind projects.

In summer of 2022, we entered a co-operation agreement with TATA Steel UK to understand and explore the production of steel components that could be used in floating wind foundations and structures for projects in the Celtic Sea.

In Autumn 2022, we commissioned Marine Power Systems (MPS) to undertake technical feasibility studies on a range of deployment scenarios of the MPS floating system utilising local ports and supply chain.

Partnerships and inter-industry collaboration will be at the heart of a successful floating wind industry within the Celtic Sea and RWE is working with all sectors to ensure that opportunities are not missed. We are engaging with local, national and global supply chains through a dedicated Supplier Engagement Platform, in conjunction with RWE’s Supplier Transparency Engagement Platform (STEP), to help promote opportunities from our investments. Find out more about the STEP initiative and our future supply chain activities through our dedicated pages.

Unrivalled technical capability in floating wind

RWE has been hard at work to build world leading expertise and knowledge on floating wind, implementing an unparalleled plan for development and deployment at a commercial scale.

Our capability programme includes pioneering demonstration projects in Spain and Norway, which provide real-life insights beyond structural competence, pointing us towards port and energy infrastructure and supply chain capability requirements, production strategies, planning and beyond, looking at how different technologies respond to varying conditions.

What is Floating Wind?

Floating wind is the next technologically innovative step in the evolution of offshore wind.

Using the same turbines as conventional offshore wind but deployed on top of floating structures, floating wind has established the means for harnessing the power of the wind in offshore regions with deeper waters, such as the Celtic Sea.

RWE has a long history in Wales

RWE is the largest power producer in Wales, and the country’s number one renewable energy generator.

We are currently involved in over 3 GW of energy in Wales across 11 sites, of which around 1 GW is renewable.
