Europe is expected to surpass 100 gigawatts of installed energy storage capacity later this month, covering the EU, UK, Norway and Switzerland, according to new analysis from LCP Delta and Energy Storage Europe.
The report, released at the Enlit Europe conference this week, said the milestone represents enough storage capacity to meet the combined peak electricity demand of Germany and the Netherlands.
Pumped-hydro storage remains the largest contributor, accounting for 50.6 GW of installed capacity, including 500 MW added this year in Belgium and Austria. Utility-scale battery storage is expanding more rapidly, with more than 4 GW of new additions in 2025 alone, the analysis said.
Residential battery sales, which surged during the early 2020s due to subsidy support, have begun to stabilise after peaking in 2022–23, the report added.
LCP Delta and Energy Storage Europe forecast that total storage capacity will surpass 215 GW by 2030, with battery systems exceeding 160 GW. By the end of the decade, annual deployments are expected to reach 20–25 GW — more than 20 times the installation rate seen in the 2020s.
Silvestros Vlachopoulos, energy storage research lead at LCP Delta, said the milestone underscores the sector’s rapid growth. “Reaching 100 GW of installed energy storage across Europe is a key moment for the market,” he said. “Keeping investors and developers engaged will be essential to scaling projects and providing the flexibility needed for Europe’s 2030 targets.”
Jacopo Tosoni, head of policy at Energy Storage Europe, said supportive regulation will determine how quickly storage can expand. “With the right policies, energy storage can maximise our homegrown green energy while lowering bills for households and industry alike,” he said. “It has the potential to become the engine of Europe’s competitiveness.”
