What Kendall Sustainable Infrastructure does
Kendall Sustainable Infrastructure, LLC (KSI) is a privately held development, finance, and asset management firm that develops, finances, owns, and operates distributed-scale sustainable infrastructure assets—primarily solar, with adjacent storage and water resource investments. Founded around 2011 as an affiliate of Kendall Investments, LLC (established 2004) and headquartered at 6 University Road in Cambridge, Massachusetts, KSI has deployed approximately $500M of capital across more than 80 distributed infrastructure transactions and owns or operates 130 MWdc of completed solar capacity across eight US states (New York, New Jersey, California, Vermont, New Hampshire, Rhode Island, Oregon, and Illinois), with an additional 60 MWdc under active construction as of February 2026.
KSI operates as an independent power producer with three interlocking revenue streams: (1) project finance and take-out financing for developers and EPC contractors on assets typically between $500K and $25M, (2) long-term ownership of operating distributed-scale solar assets monetized through PPAs, net metering, and tax-equity–supported economics, and (3) asset management services for its investor LPs. Its go-to-market relies on deep, repeat relationships with regional developers and EPC contractors rather than competitive bidding. The capital stack includes senior secured debt from Prudential Private Capital (PGIM) and Cambridge Savings Bank, tax equity from Nelnet Solar and Monarch Private Capital, and institutional co-investment via Manulife Investment Management (which funded the December 2024 CleanCapital acquisition of KSI's 22.7 MW portfolio, concluding the lifecycle of KSI's first fund). Off-takers span municipalities, universities, schools, and hospitals (MUSH segment); commercial and industrial buyers such as Corning and Cornell University; and over 800 community solar subscriber households.
