Europe on the verge of 100 GW of energy storage
Europe is entering a new phase of energy infrastructure development. Later this month, the total installed capacity of energy storage systems in the EU, the UK, Norway, and Switzerland is set to exceed 100 GW, according to the latest analysis by LCP Delta and Energy Storage Europe, presented at the Enlit Europe 2025 conference. Surpassing this milestone marks a symbolic stage in the market’s development and a tangible proof that energy storage has become one of the pillars of Europe’s energy transition. Analysts predict that by 2030, the continent will reach over 215 GW of storage capacity, of which 160 GW will be battery storage.
Batteries growing at a rapid pace
Despite strong interest in battery energy storage, pumped-storage hydropower still holds the largest share of Europe’s storage mix. Their total capacity reaches 50.6 GW, including the newly commissioned 500 MW in Belgium and Austria.
However, the battery sector is growing much more dynamically. In 2025 alone, more than 4 GW of large-scale battery installations were added. This is driven by falling technology costs, an increasing number of storage-focused auctions, and the need to rapidly integrate variable renewable energy (VRE) into power systems.
By segment, the growth looks as follows:
- C&I (Commercial & Industrial) – Storage for businesses has become an important tool for cost optimization and supporting self-consumption of renewable energy. In 2025, this segment saw steady growth, driven by high energy prices, dynamic tariffs, and increasing reliability requirements.
- Residential segment – After a boom in 2022–2023 fueled by subsidies, the market has stabilized. Analysts expect solid growth to return between 2027–2030, supported by PV market recovery, heating electrification, e-mobility expansion, and new financing models (energy leasing, subscriptions, dynamic tariffs).
Energy storage as a foundation of the European energy mix
Reaching 100 GW of energy storage is strategically significant. Resources of this scale can cover peak electricity demand equivalent to the combined consumption of Germany and the Netherlands. At the same time, as Silvestros Vlachopoulos, Head of Energy Storage Research at LCP Delta, emphasizes: “This is a key moment for the market. Energy storage opens space for greater renewable generation and lays the foundation for even faster growth in the coming years.”
Increasing storage capabilities allow transmission and distribution system operators to balance the system effectively, eliminate grid bottlenecks, and reduce renewable curtailment. They also provide flexibility for managing capacity markets and system services.
Growing investment attractiveness and accelerating policy support
Rapid development is expected particularly for large utility-scale battery installations. Their competitiveness is improving due to:
- declining costs of lithium and LFP cells,
- new contract models, including flexibility contracts,
- targeted auctions conducted in an increasing number of countries,
- growing profitability of energy arbitrage in systems dominated by renewables.
As Jacopo Tosoni from Energy Storage Europe notes: “Energy storage is the fastest-growing clean technology in Europe. Proper policies can turn energy storage into a driver of competitiveness for our industry.” Regulations on flexibility services, electricity market modernization, and storage obligations will become key investment drivers in the coming years.
Challenges and necessary actions
To maintain and accelerate the growth of the energy storage market, Europe must address several critical challenges:
- Standardization and simplification of grid connection procedures, which currently hinder investments in many countries.
- Creation of stable and predictable business models, including long-term flexibility service contracts.
- Modernization of distribution networks to enable integration of growing volumes of local resources.
- Support for new technologies, such as long-duration energy storage (LDES), essential for full system decarbonization.
According to forecasts by LCP Delta and Energy Storage Europe, by 2030 total storage capacity in Europe is expected to exceed 215 GW (including over 160 GW of battery storage), with annual capacity additions estimated at 20–25 GW.
