What Greenskies Clean Focus does

Greenskies Clean Focus is a vertically-integrated U.S. commercial solar developer founded in 2009 in Connecticut (originally as Greenskies Renewable Energy) and headquartered in North Haven, CT. The company originates, develops, constructs, finances, owns, and operates distributed solar projects — including rooftop, ground-mounted, carport, and agrivoltaic installations — augmented by battery storage, microgrids, and CCHP offerings. Since founding it has developed more than 395 MW across 710+ sites in 19 states, ranking as the No. 1 commercial solar developer in the Northeast and a top-three U.S. commercial solar owner per Solar Power World.

The business is structured around a Clean Focus affiliate that finances and owns the systems while Greenskies handles end-to-end development and operations, enabling 15-25 year power purchase agreements (PPAs) with zero upfront cost to customers. Target segments are commercial and industrial buyers, municipalities and school districts, nonprofits/universities/hospitals, landowners, and utility/community-solar subscribers, served through direct enterprise sales, an EPC channel-partner network (Vanguard Energy Partners, Pfister Energy, Eznergy), energy consultancies (Titan Energy), and partnerships such as Connecticut Green Bank and Cape & Vineyard Electric Cooperative.

Greenskies is privately held, with strategic investment from Hull Street Energy and JLC Infrastructure in October 2023. Leadership includes CEO Vijay Singh (appointed March 2026, formerly NextEra Energy and PPL Corp.), CCO Dan O'Brien, and VPs of Power Marketing and Project Finance. The firm employs 101-250 people with additional offices in Pleasanton, CA and New York, NY.
