Denham Sustainable Infrastructure

What Denham Sustainable Infrastructure does

Denham Sustainable Infrastructure (DSI) is the energy transition-focused investment platform of Denham Capital Management LP, a private equity and credit firm founded in 2004. DSI deploys institutional capital into three core strategies: Sustainable Infrastructure Equity (global mid-market equity investments in sustainable infrastructure assets), Sustainable Infrastructure Credit (direct lending to investment-grade and below-investment-grade sustainable infrastructure companies), and Mining (financing for critical metals and minerals). The Denham platform has raised over $12 billion across multiple fund vehicles and manages a 12,800 MW portfolio of power generation assets spanning wind, solar, hydro, gas-fired generation, and battery storage across 30+ countries, with offices in Boston, Jersey City, and London.

DSI's portfolio comprises directly-owned and co-owned operating businesses including Gray Oak Power (customized firm power for U.S. hyperscale data centers), Virtue Power (U.S. distributed solar), Ceiba Energy (Latin American power), Endeavor Energy (African independent power generation with 450 MW under construction), Roam (UK EV fast-charging infrastructure), Pontal Energy (~1 GW Brazilian renewables), and Serra Verde (Brazilian ionic clay rare earths). The credit strategy was anchored in July 2021 by a $2 billion commitment from Aflac Global Investments, with additional green bond investments in South Jersey Industries ($80 million) and Hawaiian Electric Industries ($35 million). The Mining platform separately manages over $2 billion in commitments.

DSI generates revenue through management fees on committed and invested capital (standard institutional fund terms, typically 1-2%), carried interest on successful exits (typically 20% above hurdle), and credit investment returns. The firm distributes capital through direct institutional LP relationships with pension funds, insurance companies, and sovereign wealth funds, and originates investments through industry networks and existing portfolio relationships. The firm is signatory to the Principles for Responsible Investment and aligns investments with IFC Performance Standards.
