What’s driving Europe’s battery boom? Insights from EUPD Research’s Business Climate Survey and Storage Report Europe’s battery storage market is projected to nearly double from 34 GWh in 2025 to 65 GWh in 2026, driven primarily by utility-scale projects and growing renewable energy integration. Meanwhile, intensifying competition in residential and commercial storage is pushing manufacturers toward integrated energy solutions, strategic partnerships, and advanced energy management technologies.

Age awareness for BESS As the use cases for battery energy storage systems (BESS) evolve, so does the way the batteries are operated. How these changes affect BESS lifetime and reliability is a question the industry needs answered, and one the International Energy Agency’s Photovoltaic Power Systems Programme (IEA-PVPS) is working to address. Erik Marstein, director of Norwegian PV Research Center FME Solar, outlines the results of recent research into BESS reliability and how asset owners can take system aging into account in daily operations.
