Buying solar means comparing equipment, financing and promises about the next 25 years. EnergySage built a business by putting those promises on the same page - and now wants to do the same for the rest of the electric home.

The lawyer-turned-developer learned that solar runs on statutes, queues and trust as much as sunshine. At Arena Renewables, that education became a near-1 GW pipeline and an acquisition before the company’s third anniversary.

The Boston founder built Resonant Energy around a stubborn idea: clean power should lower costs for nonprofits and affordable housing, not wait for the easiest roof and richest owner.
Isaac Baker and Ben Underwood built a solar company around the customers the industry finds too poor or too complicated. Nearly a decade in, the affordable-housing rooftops are paying them back.
Three industry veterans bet that community solar's real money is in development, not ownership. Two and a half years later, Headwater Energy bought the whole pipeline.
True Green Capital built its business in the awkward middle of renewable energy: projects too small for utility-scale giants, yet too capital-intensive for many developers. Its answer is to assemble, operate and eventually sell them at institutional scale.
Born to electrify farms that private utilities passed over, GVEC now links poles, fiber, thermostats and home batteries into one regional system. Its next trick is turning thousands of member-owned devices into useful capacity for the Texas grid.
Ampion, PBC is a Boston-based public benefit corporation and software platform for community solar and distributed generation. Its enterprise technology handles subscriber acquisition, billing, revenue management, customer care, and sustainability reporting for solar asset owners, connecting households and businesses to local solar farms so they can lower electricity bills without rooftop installations or upfront costs. Ampion manages hundreds of megawatts across multiple U.S. states and has saved subscribers more than $42 million in electricity costs.
Nate Owen is the founder and CEO of Ampion, a Boston-based Public Benefit Corporation that acquires and manages community solar subscribers across the country. He started Ampion in 2014 after two decades running Energy Services Group, the back-office software company he founded in 1996 to serve the newly deregulated electric and gas markets. Under Owen, Ampion has grown to roughly 120 employees, manages about 1.5 GW of community solar capacity, and says it has saved subscribers more than $42 million on their electricity bills.
Public Grid is a climate-tech company building a software layer on top of the existing electric grid so households can switch to renewable energy and find savings without hardware, paperwork, or gatekeeping. Its platform sits on top of a user's utility account, brokers bulk green-energy contracts, applies local incentives, and surfaces cleaner, cheaper options in one click. Founded in 2022 (originally as Cottage Energy) and based in New York City, Public Grid says it serves 25,000+ households and is backed by Redbud VC and Hamilton Ventures.
