Mubadala committed US$325 million to Ørsted’s Hornsea 3 offshore wind project in the UK in May 2026. The investment sits alongside Apollo-managed funds, USS, and La Caisse, after Apollo acquired a 50% stake in the joint venture holding the 2.9GW under-construction project. Ørsted retains the remaining 50% and will continue development, construction, and operations.

The shift in UK offshore wind M&A is clear. Developers are using consortium equity to fund large construction programs while keeping operating control. For buyers, the attraction is exposure to a gigawatt-scale infrastructure asset in a mature offshore wind market, without taking full development responsibility.

Apollo’s earlier US$6.5 billion commitment covered a 50% stake and funding for half of Hornsea 3’s remaining construction costs. Mubadala’s entry adds sovereign capital to a structure already backed by private capital and pension institutions.

This mirrors broader European deal behavior. Enerdatics’ Q3 2025 M&A report noted that PE-led acquisitions accounted for 45% of European deal volume, with large infrastructure investors targeting de-risked renewable platforms and assets.

The commercial reason is balance-sheet efficiency. Ørsted monetizes part of a capital-intensive offshore wind asset, while Apollo and co-investors secure long-duration infrastructure exposure before completion.

Hornsea 3 signals that UK offshore wind M&A is moving away from full platform takeovers and toward staged, consortium-backed ownership of mega-projects.
