Since we first embarked into offshore wind two decades ago with our first co-development, the 25MW Arklow Bank project in the Irish Sea, we have grown to become a world-leader in offshore wind.

In the 20 years since, we have contributed to the development and delivery of over 2.5GW of installed offshore wind farms already operating in UK and Irish waters, including the 0.5GW Greater Gabbard1, the 0.6GW Beatrice2 and the 1.1GW Seagreen3 offshore wind joint venture sites which we operate daily on behalf of our asset partners.

Seagreen is now Scotland’s largest and the world’s deepest fixed bottom offshore wind farm.

Today, we’re leading the construction of the 3.6GW Dogger Bank4 on behalf of our asset partners Equinor and Vårgrønn, the world’s largest offshore wind farm currently in delivery which represents a total £9bn spend in infrastructure capex.

We also have the largest secured offshore wind development pipeline in the UK and Ireland at over 9GW. This includes projects such as Ossian5, our first commercial-scale venture into floating wind, and Berwick Bank which is setting new biodiversity standards.

Still in our core markets, our unrivalled 5GW future pipeline of prospects includes a potential fourth phase for the world’s largest offshore wind farm, Dogger Bank, as well as over 3GW of new capacity around Ireland at Celtic Sea Array, Setanta and Tarbert.

Internationally, we’re expanding into new markets where the offshore wind opportunity is immense and critical to achieving significant emissions reductions.
