Green Investment Group

Global Head Mark Dooley has operational control of the platform. He oversees a regional structure in which Edward Northam runs UK and European development, while CEO Jonathan Cole leads Corio Generation, the group’s dedicated offshore wind subsidiary. Ultimate investment committee authority and balance-sheet deployment sit within Macquarie Asset Management.

GIG originates projects through in-house development teams rather than relying on third-party auctions or brokered acquisitions. Its roots as the UK Green Investment Bank gave it a developer’s balance-sheet capability: it secures land, permits, and grid connections directly, then builds and operates the assets. This vertically integrated approach produces a pipeline of utility-scale projects across the UK, Europe, and Australia.

Neither. GIG is a wholly owned subsidiary of Macquarie Group and operates within Macquarie Asset Management as a developer-investor in physical infrastructure. It does not function as a family office, a venture capital firm, or an independent fund manager — its capital comes from the Macquarie balance sheet and its managed funds.

The group develops and invests directly in hard-asset projects, not through third-party fund commitments. GIG originates, constructs, and owns utility-scale wind, solar, and battery storage projects on the Macquarie balance sheet and for Macquarie-managed institutional vehicles. It does not act as a limited partner in external green funds.

Macquarie Group acquired the UK Green Investment Bank from the UK Government in 2017, merged it with Macquarie Capital’s renewables team, and rebranded the combined entity as Green Investment Group. In 2022, GIG was moved into Macquarie Asset Management, where it operates as the specialist green infrastructure development and investment arm.

GIG typically leads its own developments rather than co-investing alongside external fund managers in blind-pool structures. Its model depends on in-house origination and development capability. When external capital is involved, it comes through project-level financing or institutional funds managed by Macquarie Asset Management, not through passive LP relationships with other managers.

GIG’s mandate is limited to the green energy transition. The firm does not invest in fossil-fuel generation, downstream oil and gas infrastructure, or traditional thermal power assets. Its portfolio is restricted to renewable generation, energy storage, and enabling grid infrastructure.
