What Climate Adaptive Infrastructure does
Climate Adaptive Infrastructure (CAI) is a San Francisco-based private infrastructure investment firm founded in 2019 that invests to accelerate deep decarbonization across three focus areas: water, energy, and urban infrastructure. CAI provides growth equity and strategic capital to climate infrastructure companies, with disclosed portfolio companies spanning solar PV and battery storage independent power production (IPX Power, 4.4 GW solar and 8.8 GWh storage in California and Texas), community solar and distributed renewables (38 Degrees North, including its 250+ MW U.S. Light Energy acquisition), and atmospheric water generation technology (Aquaria, with Hydrogrid technology targeting commercial real estate, green hydrogen, mining, and data centers). The firm operates an enterprise, relationship-driven go-to-market, originating and executing transactions directly with institutional capital partners — including TPG Rise Climate, Google/Alphabet, Greenbelt Capital Partners, and Kimmeridge Energy Management — rather than intermediated distribution. CAI's most notable transaction is its participation as a lead shareholder in the $4.75 billion sale of Intersect Power to Alphabet (one of the largest private renewable energy exits in history), followed by the March 2026 spin-out of grid-tied assets into IPX Power at a combined $12 billion enterprise value.
The firm generates revenue through returns on equity investments, capital appreciation, and management of infrastructure assets; pricing details are not publicly disclosed, consistent with the firm's private investment manager status. CAI is led by co-founder and managing partner Bill Green, with Aaron Gold appointed Partner and President in April 2026 (formerly Managing Director at Argo), bringing over 30 years of infrastructure investment experience. The firm is recognized in the industry as a 2023 finalist for Infrastructure Investor's Energy Transition Investor of the Year, North America award. CAI's strategic positioning targets the projected ~250 GW of new U.S. power capacity required by 2030, with portfolio exposure to renewable generation, energy storage, and water infrastructure designed to monetize the intersection of AI-driven electricity demand and the energy transition.
