Working in partnership with UK suppliers

Introducing offshore wind in the UK

RWE has been pioneering offshore wind in the UK for more than two decades. Blyth, our first venture into offshore wind, was commissioned in 2000. Since then, both our technical expertise and offshore portfolio have grown substantially

Currently in the UK, we have 10 operational offshore wind farms, have one under construction and a further 6 in development making us one of the largest developers in the UK.

Introducing offshore wind in the UK

Growing the UK pipeline

RWE recognises suppliers as being the backbone of our success. Throughout our journey, we have sought to maximise UK supplier opportunities, working in partnership with our skilled and diverse supplier network. Together, we have been at the forefront of innovation and driven both regional and industry-wide successes in terms of local regeneration, job creation, Gross Value Add (GVA), infrastructure opportunities and enhanced supplier capabilities.

All of which contribute to the success of the UK market globally.


Up to £ 00 billion

00 %

of O&M spend at project level at GyM was with UK based suppliers in 2022 (£65million)

Out of 00 suppliers

used by Rampion Offshore Wind Farm in 2022, 145 were UK based (86%)

Championing supplier development

RWE works closely with UK Government, other developers and suppliers to facilitate supply chain growth. Via the Offshore Wind Industry Council (OWIC) we are helping to shape the policies that will realise the UK Government’s ambition of 50GW by 2030.

At a regional level, we recognise the importance of creating opportunities to deliver new supplier networks and regional growth by fostering local businesses, skills and innovation activities, via industry clusters including the Offshore Energy Alliance which we established in 2019.

Supporting supplier innovation

RWE has been driving UK innovation as a leader or active participant in many UK research programmes. Examples of collaboration include those with key parties such as the Offshore Renewable Energy Catapult (OREC) and The Carbon Trust. We recognise innovation as a crucial component to supplier growth and overall UK market success and are committed to ongoing collaborative efforts to engage in this way.

We also collaborate at a local project basis with a range of universities and R&D institutes, to drive knowledge creation in the offshore sector. Most recently, RWE’s state-of-the-art Sofia construction project has been actively involved in OREC’s Launch Academy. Through this, small innovative companies are able to address project-specific and wider industry challenges, as identified by RWE.

Continuously advancing the supplier network

We understand our role in advancing UK supplier capability and consider this across our project, company and industry level engagements. Through the development of tailored Supply Chain Plans our projects are delivering on commitments across green business growth, infrastructure investments, innovation and skills to aid the development of our future workforce and industry. 

We work via Memorandum of Understandings (MoUs) and other initiatives to explore valuable relationships with prospective supplier partners, funding studies and working in partnership where we see potential. At an industry level, we work with our counterparts to identify challenges and pose solutions that enable vital growth and success.

Supply Chain Plans

The UK government’s Supply Chain Plan (SCP) process is in place for renewable projects over 300MW applying for a Contract for Difference (CfD). The process requires developers to submit a document containing commitments across the categories of: Green Growth, Infrastructure, Innovation and Skills. Through the SCP process, RWE’s recent Triton Knoll and Sofia Offshore Wind Farms have undertaken a range of initiatives, showcasing success right across the four categories.

RWE is committed to high quality SCPs across all of our project developments.
