Green Investment Group

What Green Investment Group does

Green Investment Group (GIG) is a specialist green infrastructure investment and development platform operating as a wholly-owned subsidiary of Macquarie Group within Macquarie Asset Management's Real Assets division. Headquartered in the UK, GIG mobilizes institutional capital into renewable energy and energy transition assets across offshore wind, onshore wind, solar, battery storage, bioenergy, CCUS, hydrogen, and EV charging infrastructure. The business operates across 25+ markets with 450+ employees and has committed or arranged over £26 billion into green energy projects since 2012, with 85+ GW of projects in development as of September 2022.

GIG's operating model combines principal investment with third-party capital mobilization through managed funds. Its revenue derives from fund management fees (notably MGREF1, MGREF2 at €1.6 billion, and MGETS), carried interest on successful investments, and returns from direct equity stakes on the balance sheet. GIG serves three primary customer segments: institutional investors (pension funds, sovereign wealth funds, insurers) committing capital to managed funds; governments (notably the UK Government as JV partner in UK Climate Investments) deploying public climate finance; and corporate energy buyers (Amazon, Tesco, Axpo, Dominion Energy) contracting renewable PPAs from GIG's portfolio companies.

GIG executes its strategy through a portfolio of eight specialist development platforms (Corio Generation for offshore wind, Cero Generation for European solar, Blueleaf Energy for APAC renewables, Savion and Galehead for US solar, Eku Energy for battery storage, Fleete for EV infrastructure, and HyCC for green hydrogen) plus three investment vehicles (MGREF1, MGREF2, and UK Climate Investments). The platforms operate as specialist development businesses that originate and develop projects, while the funds provide the capital to scale them. GIG's governance is differentiated by five binding Green Purposes enshrined in its Articles of Association, with the independent Green Purposes Company holding a special share requiring consent for any changes — a structural commitment to green objectives that institutional investors cite as a credibility differentiator.
