SharedSolar develops and deploys smart microgrids that combine renewable energy, metering, and storage management to deliver reliable, grid-like electricity in off-grid communities. Its pay-as-you-go model lets customers prepay in flexible amounts while real-time data helps operators manage demand and gives users visibility into their energy use. The Columbia Sustainable Engineering Lab project has carried out field work in places including Uganda and Mali.

The company also provides installation, training, remote monitoring and technical support, with deployments ranging from farms in Maryland to agricultural operations in the Democratic Republic of Congo and Tanzania.POTOMAC, MD
Crawford Solar PowerCrawford Solar Power develops sculptural solar trees with integrated battery storage and links them into EDEN, a distributed network designed to generate local power and support electric-vehicle charging. Its concept combines renewable-energy infrastructure with community uses such as vehicle rentals and driving schools, and the company is seeking founder-donors to launch an automated solar tree factory.CORONA, NY
YansaFounded in 2009, Yansa develops community-controlled wind farms, providing the technology, capital, training and management needed to bring locally governed renewable energy projects to life. Its pilot project partners with the Zapotec community of Ixtepec in Oaxaca, Mexico, where wind-farm revenues are directed toward priorities chosen by residents while the community retains control of its land and resources. The Yansa Group combines a nonprofit foundation focused on community welfare with a technical arm that plans projects and secures financing.NEW YORK, NY
AGreatE IncFounded in 2017 by scientists and engineers based in New York State, AGreatE develops lithium-ion battery energy-storage systems for renewable-power, microgrid, commercial, and residential applications. Its Wattainer systems use compact, modular battery architecture and AI-embedded management software designed to improve system safety, maintenance, and energy use. The company also extends that work to off-grid applications, including a portable DC power system and a solar clean-cooking ecosystem being piloted in Cameroon.BINGHAMTON, NY
