FlexGen provides integrated energy storage solutions by designing and deploying battery energy storage systems (BESS) and pairing them with HybridOS, a proprietary software platform that manages and optimizes these assets. The product combines hardware and software to enable automated energy dispatch from batteries, solar/wind, and conventional generators to meet grid demands. It can manage a single site or an entire fleet of storage assets and delivers real-time data and performance analytics. Unlike competitors that may focus on either hardware or software alone, FlexGen offers a tightly integrated, software-first solution that coordinates multiple energy sources and storage assets in one system. Its goal is to support the energy transition by stabilizing the power grid, integrating renewable energy, and ensuring reliable power supply for utilities, independent power producers, and large industrial customers, while optimizing asset performance and cost for its customers.
