Founded 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.

Viridi Parente, IncFounded in 2009, Buffalo-based Viridi Parente manufactures American-made, fail-safe lithium-ion battery energy storage systems for distributed power, including installations inside occupied and mission-critical buildings. Its proprietary anti-propagation technology is designed to contain thermal events at the cell level, while integrated AI and remote monitoring help customers manage power and resilience. Viridi has completed more than 500 deployments across North America and operates a 160,000-square-foot smart manufacturing facility in Buffalo.BUFFALO, NY
Key Capture EnergyFounded in 2016, Albany-based Key Capture Energy develops, constructs, owns and operates utility-scale battery energy storage systems that help balance the U.S. electric grid. The independent power producer uses in-house market optimization software to manage its batteries, with more than 620 MW operating and a development pipeline exceeding 10,000 MW across the country. Its projects span from New York to Texas and are designed to make renewable power available when the sun is not shining or the wind is not blowing.ALBANY, NY
Stryten EnergyFrom its Alpharetta headquarters and a network of U.S. manufacturing plants, Stryten Energy makes batteries and energy-storage systems for everything from microgrids and warehouses to cars, trains and trucks. Its vertically integrated domestic supply chain supports nearly 15 gigawatt-hours of annual storage capacity, spanning advanced lead, lithium and vanadium redox flow technologies alongside intelligent chargers and fleet-management software. The company’s Salina, Kansas, plant has manufactured batteries for 50 years and employs more than 700 people in the surrounding county.BRIDGEVILLE, PA
EticaAGEticaAG, a joint venture between Etica Battery and AssetGenie, manufactures U.S.-made lithium-ion battery energy storage systems built around LiquidShield immersion cooling. Founded from Etica Battery’s 2002 battery-manufacturing heritage, the company submerges cells in dielectric fluid to control heat and prevent thermal propagation, while its HazGuard system neutralizes hazardous off-gases. EticaAG manufactures in New York and offers FEOC-, BABA- and BAA-compliant systems for safety-sensitive energy projects.GREENSBURG, PA
