Abu Dhabi sovereign investor Mubadala Investment Company has announced a USD 325 million investment in the Hornsea 3 offshore wind project being developed by Danish energy company Ørsted off the Norfolk coast in the United Kingdom.

Once completed, Hornsea 3 is expected to hold the title of the world's single largest offshore wind farm, with a planned capacity of 2.9 gigawatts capable of powering more than 3.3 million UK homes.

Consortium Structure and Ownership

Mubadala is joining a consortium led by Apollo-managed funds, alongside the Universities Superannuation Scheme, known as USS, and La Caisse, the Canadian pension fund manager.

The consortium's involvement in Hornsea 3 follows Apollo Funds' acquisition of a 50 percent stake in the joint venture that holds the project. Ørsted retains the remaining 50 percent ownership and will continue to lead the development, construction, and operation of the wind farm.

The transaction deepens an existing relationship between Mubadala and Apollo, with the two firms having previously worked together on infrastructure investments. Mubadala described the deal as a further strengthening of that partnership.

Scale and Strategic Significance of Hornsea 3

Hornsea 3 is Ørsted's third gigawatt-scale offshore wind project within the Hornsea zone in the North Sea. The project's planned output of 2.9 gigawatts places it in a category of infrastructure that Mubadala characterized as a generational asset.

Apollo Infrastructure Partner Adam Petrie described the project as having "the capacity to provide reliable, renewable power to over 3 million homes across the UK."

The United Kingdom represents the largest offshore wind market outside China, and the country has set a target of up to 50 gigawatts of offshore wind capacity by 2030 as part of its broader net-zero ambition.

UK electricity demand is expected to more than double by 2060, driven by structural shifts across transport, heating, and digital infrastructure, according to Mubadala's announcement.

Mubadala's Rationale for the Investment

Karim El Jazzar, Head of EMEA Infrastructure at Mubadala, said the investment reflects the firm's approach of partnering with experienced operators in high-quality infrastructure assets that support the energy transition while delivering long-term value.

He noted that as electricity demand continues to grow, projects of Hornsea 3's scale will play a critical role in expanding generation capacity and supporting the transition to a more sustainable energy system.

The investment aligns with Mubadala's broader strategy of building out a global renewable energy portfolio. The Abu Dhabi sovereign investor has previously committed capital to a range of renewable platforms, including Tata Power Renewables in India, Skyborn Renewables, PAG Renewables, and Rezolv Energy. Hornsea 3 adds a major European offshore wind asset to the existing collection of clean energy holdings.

Apollo's Perspective on the Consortium

Adam Petrie, Infrastructure Partner at Apollo, said Mubadala is an exceptional partner and that the firm was pleased to welcome them into the Hornsea 3 consortium.

He pointed to the composition of the investor group, which includes leading institutional investors, as a reflection of the quality and scale of the project. Petrie's comments underscored Apollo's view of Hornsea 3 as a long-duration infrastructure asset with durable revenue characteristics tied to the UK's regulated offshore wind market.

UK Offshore Wind Policy Context

The United Kingdom's offshore wind sector operates within what Mubadala described as a stable regulatory environment backed by long-term policy commitment.

The country's 50 gigawatt target for offshore wind by 2030 represents a significant expansion from current installed capacity and underpins the commercial rationale for large-scale investments such as Hornsea 3.

Rising electricity demand projections, expected to more than double by 2060, further support the long-term investment case for offshore generation assets of this scale.

The Norfolk coast location of Hornsea 3 places it within the North Sea, a region that has become the center of gravity for the global offshore wind industry outside of Asian markets.

Ørsted's Hornsea zone has already produced two previous gigawatt-scale projects, with Hornsea 3 representing the third and largest installment in that program.

Mubadala's Broader Infrastructure Activity

The Hornsea 3 announcement is one of several infrastructure and investment transactions Mubadala has disclosed in 2026. The Abu Dhabi firm has also announced a partnership with Stonepeak to invest in container leasing platforms, an acquisition of a minority stake in Power Factors, and a joint venture with Aldar that acquired an asset at Masdar City.

The firm also sold a minority stake in CoolIT to Ecolab as part of a KKR-led transaction valued at USD 4.75 billion. The USD 325 million commitment to Hornsea 3 was announced from Abu Dhabi and represents one of the more substantial single renewable energy investments Mubadala has disclosed in recent months.

The project's expected completion would deliver a landmark moment for the UK's offshore wind sector and for the consortium of investors backing the venture.
