FlexGen Power Systems is a Durham, North Carolina energy storage technology company founded in 2009 that designs, integrates and operates grid-scale battery energy storage systems (BESS) and the software that runs them. Its flagship product is HybridOS, a hardware-agnostic energy management system (EMS) for multi-source, multi-site battery and solar portfolios, alongside HybridOS Control BMS (a US-built battery management system), a solar power plant controller (PPC), EMS retrofit, activation and lifecycle services, and data-center power solutions. FlexGen has been named a BloombergNEF Tier 1 energy storage company, acquired Clean Energy Services (CES) and the assets of Powin, and states that HybridOS exposes automated APIs and historian data API access to customers.
