According to Sawyer Merritt, 2025 marked a major milestone for Battery Energy Storage Systems as global operational storage capacity exceeded 250 GW, surpassing pumped hydropower for the first time. Annual additions reached over 100 GW or 280 GWh, nearly tripling from previous years. This rapid growth in energy storage is enabling increased integration of AI-driven energy management systems, opening new business opportunities for predictive analytics, machine learning optimization, and real-time grid balancing, as reported by Sawyer Merritt.
