About

synthesis · audited 2026-08 as of 2026-07

An Australian financial group whose green energy activity has run through specialist platforms — the Green Investment Group, acquired from the UK government, and later the dedicated offshore developer Corio Generation. It sits awkwardly between categories: an asset manager by ownership, but one that originates and develops projects rather than only buying built ones, which is why it appears among developers here. Its portfolio is wide and heavily weighted to development-stage assets.

Strategic read

Macquarie acquired the UK Green Investment Bank (£2.3bn, 2017) and built one of the world's largest offshore wind investment platforms under Mark Dooley. GIG deployed capital aggressively: East Anglia ONE (40%, ~£1.7bn), Japan JV with Iberdrola (3.3 GW), UK Round 4 (1.5 GW with Total), MGREF2 fund (€1.6bn), ScotWind 2 GW. Spun out Corio Generation (March 2022) as a standalone developer with 15+ GW pipeline. GIG moved into Macquarie Asset Management (April 2022). In April 2024, Corio announced a $50bn investment plan across 30 GW — the peak ambition statement. Reversal was swift: Macquarie explored selling Corio (Oct 2024), laid off staff (Dec 2024), and abandoned the sale (Apr 2025) due to lack of buyer interest. Corio refocused on a "smaller portfolio." Failed exit is the clearest bearish signal — from "enormous game" (2019) to failed sale in six years.

    Bloomberg interview — Corio Generation $50 billion offshore wind investment
    “Whether by good luck or excellent management, we find ourselves in a situation where we were born and came onto the market only two years ago. We haven't found ourselves in a situation where we've had to make cancellations of projects and write-offs.”
    Jonathan Cole, CEO, Corio Generation source →
  5. 2023-10 cautious
    Bloomberg New Economy Forum, Singapore
