Top 10 Best Wind Energy Companies in Isle of Anglesey

Wind Power Around Anglesey

Wind has always shaped life on the Isle of Anglesey. The island's historic windmills, such as Melin Llynon near Llanddeusant, are a reminder of how its exposed landscape has long been used to harness the breeze. Today, modern turbines are doing the same work on a far larger scale. Onshore wind farms have operated on the island for decades, and the waters of the Irish Sea off North Wales host some of the UK's most significant offshore wind farms.

The next wave of development is even more ambitious. New offshore projects planned for the Irish Sea will generate gigawatts of clean electricity, requiring ports, operations and maintenance bases, grid connections and skilled workers. Anglesey, with its deep-water port at Holyhead and its engineering heritage, is well placed to benefit.

How We Selected These Companies

We considered companies operating or developing wind projects near Anglesey, major turbine manufacturers supplying the region, port and supply chain organisations and industry bodies influencing policy. We prioritised scale, track record and relevance to the island.

The Top 10 Wind Energy Companies Linked to Anglesey

1. RWE

RWE is the leading offshore wind operator off the North Wales coast, with projects including Gwynt y Môr, North Hoyle and Rhyl Flats. Its proposed Awel y Môr extension will add substantial new capacity, reinforcing the region's role in the UK's clean energy system.

2. bp

bp, in partnership with EnBW, is developing the Mona and Morgan offshore wind projects in the Irish Sea. Mona in particular is planned with a grid connection into North Wales, creating major opportunities for local supply chains.

3. EnBW

EnBW, a German energy company with extensive offshore wind experience, is bp's partner on Mona and Morgan. Its expertise in delivering large-scale offshore projects brings valuable know-how to the Irish Sea region.

4. Ørsted

Ørsted is a global offshore wind leader operating several major wind farms in the eastern Irish Sea, including Burbo Bank and Walney. Its regional presence supports a wider North West and North Wales offshore wind supply chain.

5. Siemens Gamesa Renewable Energy

Siemens Gamesa is one of the world's leading turbine manufacturers, with turbines installed across many UK offshore wind farms, including those off North Wales. Its UK manufacturing and service operations create skilled jobs across the sector.

6. Vestas

Vestas is a Danish wind turbine manufacturer with a huge global fleet of onshore and offshore turbines. Its machines are widely used across the UK, and its service technicians maintain turbines in challenging coastal environments.

7. Port of Mostyn

The Port of Mostyn on the Dee Estuary has played a key role in constructing and operating North Wales offshore wind farms. Its experience demonstrates the value of port infrastructure to the sector and offers lessons for Holyhead's future role.

8. Statkraft

Statkraft, Europe's largest generator of renewable energy, operates onshore wind farms in Wales and invests in grid stability services. Its long-term commitment to Welsh renewables makes it an important player in the national energy transition.

9. Bute Energy

Bute Energy is a Welsh onshore wind developer planning a portfolio of projects across Wales along with associated grid connections. While its projects are primarily in mid and south Wales, it is part of the wider debate about onshore wind's role in the country.

10. RenewableUK Cymru

RenewableUK Cymru is the trade association representing the renewable energy industry in Wales. It brings developers, suppliers and policymakers together and advocates for investment in wind and marine energy across the country, including around Anglesey.

Trends in Wind Energy for North Wales

Offshore turbines are growing larger and more powerful, reducing costs per unit of electricity. Floating offshore wind is emerging as a future option in deeper waters. Grid connection capacity is a major constraint, with new transmission infrastructure needed across North Wales. Community benefit funds associated with wind farms support local projects, while skills programmes at Coleg Menai and other institutions prepare technicians for careers in the sector. The repowering of older onshore sites with fewer, more efficient turbines is also gaining attention.

Frequently Asked Questions

Are there wind farms on Anglesey itself?

Yes. The island has operated onshore wind farms for several decades, and offshore wind farms off the North Wales coast are visible from parts of Anglesey on clear days. Larger new offshore projects are planned further out in the Irish Sea.

What jobs does offshore wind create?

Roles include turbine technicians, marine crew, engineers, project managers, environmental specialists and logistics staff. Operations and maintenance jobs can last for the lifetime of a wind farm, often twenty-five years or more.

How can island businesses join the offshore wind supply chain?

Businesses can register with developer supplier portals, attend industry events, gain relevant safety and quality certifications and work with organisations such as RenewableUK Cymru and regional business networks to identify opportunities.

What Wind Energy Means for Anglesey

For island businesses, offshore wind creates opportunities in vessel operations, marine engineering, logistics, accommodation and catering for workforces. For young people, it offers well-paid technical careers without leaving North Wales. Balancing development with Anglesey's protected landscapes and tourism economy remains vital, but the potential for long-term economic benefit is considerable.
