Energy Storage Europe reports that installed storage capacity across Europe passed 100 GW during 2025. By the second quarter of 2026, storage had also overtaken nuclear generation in installed power capacity.
The organisation expects electrochemical storage alone to add a further 153 GW by 2030. That growth will affect equipment availability, grid rules, flexibility markets and the economics of storing electricity produced on site.
What buyers should compare
Battery capacity is only one part of the decision. Compare usable energy, charge and discharge power, inverter communication, backup behaviour, expected cycling and installation requirements. Also decide which surplus must remain electricity and which portion can be stored more simply as heat.
