Take a glance into our in-depth market intelligence. What is included in this Sample? Explore the Top 17 Battery Energy Storage Systems (BESS) companies of 2025, including Fluence, LG Energy Solution, Samsung SDI, Hitachi ABB Power Grids, TotalEnergies, Narada, Siemens Energy, GE Renewable Energy, Kokam, and VRB Energy.
The global Battery Energy Storage Systems (BESS) industry is projected to reach USD 18.6 billion in 2025, reflecting strong momentum in grid modernization, renewable integration, and decarbonization initiatives.
Modern BESS achieves round-trip efficiencies of 86–94%, depending on chemistry and system architecture, making them one of the most efficient energy storage technologies available. The primary role of BESS is to store excess electricity—especially from renewables like solar and wind—and release it during peak demand or grid disturbances.
BESS units range from small residential systems under 10 kWh to utility-scale installations exceeding 500 MWh. A typical BESS includes four core components: the battery module, battery management system (BMS), power conversion system (PCS), and energy management system (EMS).
