Europe’s battery storage market is set to rise from 32 GWh in 2025 to 57 GWh in 2026, a 78% year-on-year increase, whilst the competition is fierce between the companies facilitating the growth.
The data comes from EUPD Research’s latest EES Report, supporting the integration of battery storage systems as they become critical for renewable integration and grid flexibility.
Germany and Italy lead the charge with mature installer ecosystems and established policy frameworks, while the UK’s BESS sector is scaling rapidly through expanding front-of-the-meter pipelines.
Falling battery costs and rising electricity prices are driving Europe to adopt BESS at a faster rate than ever seen before, on a commercial and industrial scale, yet the residential segment remains one of Europe’s quickest growing sectors for BESS, with installations expected to increase from 11 GWh in 2025 to 15 GWh in 2026.
With growing demand comes growing competition – in this case, the BESS supplier dynamics are heated. The gap between the top 4 competitors (Fox ESS, Huawei, BYD and Sigenergy) has closed significantly in H1 2026, showing a more balanced competitive landscape.
However, this competition is pushing brands to evolve beyond BESS systems and into neighbouring equipment, such as integrated energy solutions, with brands that combine modular storage systems, intelligent energy management and comprehensive product ecosystems gaining momentum above those who only offer BESS.
