Mubadala invests $325m in UK offshore wind farm

Abu Dhabi sovereign wealth fund Mubadala will invest $325 million (AED1.2 billion) in an offshore wind farm in the United Kingdom as part of its strategy to take stakes in high-quality global infrastructure assets.

The investment in Hornsea 3, developed by Danish energy company Ørsted, is being channelled through a consortium led by New York-based Apollo-managed funds.

Positioned off the UK’s eastern coast in the North Sea, the asset will be “the world’s single largest offshore wind farm”, Mubadala said in a statement.

The investment follows Apollo Funds’ acquisition of a 50 percent stake in the joint venture holding Hornsea 3. Ørsted will retain the remaining 50 percent stake and continue to lead the construction and operation of the project.

The Hornsea 3 project is expected to deliver 2.9 gigawatts (GW) of capacity, providing enough renewable electricity to power more than 3.3 million homes.

The UK has set a target of up to 50GW of offshore wind capacity by 2030, as part of its ambition to reach net zero. This is underpinned by rising electricity demand, expected to more than double by 2060, driven by the structural shifts across transport, heating and digital infrastructure.

Karim El Jazzar, head of EMEA infrastructure at Mubadala, said that investment in Hornsea 3 reflects the company’s approach of investing alongside experienced partners in high-quality infrastructure assets that support energy transition and deliver long-term value.

This month Mubadala took a minority stake in US-based Power Factors, supporting the global expansion of the renewable energy management software company.

Mubadala has already invested in renewable energy platforms, including Tata Power Renewables, Skyborn Renewables, PAG Renewables and Rezolv Energy.

Earlier this week the Abu Dhabi wealth fund and New York-based investment company Stonepeak agreed to co-invest $300 million to build the world’s largest container-leasing platform.

Mubadala’s $385 billion portfolio spans six continents and includes investments across multiple sectors and asset classes.

Its assets under management rose by nearly one-fifth to $385 billion in 2025.
