Western European Photovoltaic Energy Storage System

What is the European energy storage inventory?

In March 2025, the Commission launched the European Energy Storage Inventory, a real-time dashboard that displays energy storage levels across different European countries. It is the first European-level tool of its kind and offers energy storage data across a full range of technologies.

Is Germany still a leader in photovoltaics & residential storage systems?

In a country-by-country comparison, Germany is still the European leader for both photovoltaics and residential storage systems. Installation figures for 2020 indicate that the German market accounts for around 70% of the total installed capacity in the European residential storage system market, making it a force that cannot be overlooked.

Why is energy storage important in the EU?

It can also facilitate the electrification of different economic sectors, notably buildings and transport. The main energy storage method in the EU is by far 'pumped hydro' storage, but battery storage projects are rising. A variety of new technologies to store energy are also rapidly developing and becoming increasingly market-competitive.

What does the European Commission say about energy storage?

The Commission adopted in March 2023 a list of recommendations to ensure greater deployment of energy storage, accompanied by a staff working document, providing an outlook of the EU’s current regulatory, market, and financing framework for storage and identifies barriers, opportunities and best practices for its development and deployment.

How much energy storage will Europe have in 2022?

Many European energy-storage markets are growing strongly, with 2.8 GW (3.3 GWh) of utility-scale energy storage newly deployed in 2022, giving an estimated total of more than 9 GWh. Looking forward, the International Energy Agency (IEA) expects global installed storage capacity to expand by 56% in the next 5 years to reach over 270 GW by 2026.

Which country has the most residential storage systems in Europe?

Lagging behind Germany by a considerable margin, the other four countries making up the top 5 of the European residential storage system market are Italy, Great Britain, Austria and Switzerland. Together, these five countries are home to 93% of all European residential storage systems.
