Europe is set to achieve a landmark 100GW of installed energy storage this month, covering the EU, UK, Norway and Switzerland.
According to analysis presented at the Enlit Europe conference by LCP Delta and Energy Storage Europe, this milestone equals the peak electricity demand of Germany and the Netherlands. With capacity forecast to grow by 115% by 2030, storage will be vital in enabling more renewable energy on the grid.
Since 2020, storage technologies have advanced at different speeds. Pumped-hydro storage (PHS) remains dominant at 50.6GW, including 500 MW added this year in Belgium and Austria. Battery storage has expanded rapidly, with more than 4GW of new utility-scale capacity installed in 2025 alone. Commercial and industrial (C&I) systems have grown steadily as businesses seek efficiency and cost savings, while residential battery sales, after subsidy-driven peaks in 2022–2023, are now stabilising.
Looking ahead, analysts expect storage capacity to exceed 215GW by 2030, with batteries alone surpassing 160GW. Annual deployment could reach 20–25GW by the end of the decade, far outpacing the 2020s. Utility-scale projects will benefit from auctions and supportive policies, while residential sales are forecast to rebound from 2027, driven by PV uptake, electrification, dynamic tariffs and new financing models.
Silvestros Vlachopoulos, energy storage research lead at LCP Delta, said, “Reaching 100GW of installed energy storage across Europe is a key moment for the market. It not only unlocks more space for renewables on the grid today but sets the stage for even faster growth in the coming years. Keeping investors and developers engaged will be essential to scaling projects and providing the flexibility needed for Europe’s 2030 targets.”
