What Corio Generation does

Corio Generation was a London-headquartered, specialist offshore wind project developer founded in 2022 and wholly owned by Macquarie Group's infrastructure fund. The company's core activity was the development of utility-scale offshore wind farms — from early-stage consenting through to project readiness for tender, PPA, or equity-sale monetization — targeting government energy authorities and national grid operators seeking to meet renewable capacity targets. Its primary product exposures were the 1.5GW Outer Dowsing project in the UK North Sea (co-developed with TotalEnergies and Gulf Development, with up to 100 turbines and projected to power over 1.6 million UK households) and the 450MW Sceirde Rocks project off the Irish coast (developed through subsidiary Fuinneamh Sceirde Teoranta).

The business model was project-development led rather than asset-operating: Corio originated projects, secured regulatory consents and seabed agreements, formed co-development consortia with energy majors, and ultimately exited via tenders, PPAs, or co-investment equity sales. There were no disclosed consumer or commercial pricing models; project economics were determined by government tender allocations, power purchase agreements, and equity co-investment structures. Revenue was not disclosed in available materials, consistent with a pre-revenue development-stage company reliant on parent-company capital.

As of 1 April 2026 Corio Generation ceased operating as a standalone business. The Sceirde Rocks planning application had been withdrawn in January 2026 (forfeiting a €35.4 million performance bond) and the Korean unit was disbanded in April 2026 after failing to find a buyer, as part of a corporate restructuring to focus on a smaller global portfolio. Macquarie Group continues to manage a number of Corio's former projects, including Outer Dowsing. The CEO, Samuel Leupold (previously of Dong Energy / Orsted heritage), has been nominated to Orsted's board.
