Technical FAQs 4

How many battery energy storage systems were installed in Europe in 2024?

21.9 GWh of battery energy storage systems (BESS) was installed in Europe in 2024, marking the eleventh consecutive year of record breaking-installations, and bringing Europe’s total battery fleet to 61.1 GWh. However, the annual growth rate slowed down to 15% in 2024, after three consecutive years of doubling newly added capacity.

What is Europe's largest battery energy storage system?

While these projects boast massive planned capacities, the largest active BESS in Europe is now the first 400 MWh phase of ENGIE’s 200 MW / 800 MWh system in Vilvoorde, Belgium, which has officially gone live. Sungrow and ENGIE bring Europe’s largest battery energy storage system online in Belgium with the completion of its first 400 MWh phase.

Why is battery storage so important in Europe?

Markus Elsaesser, the CEO of Solar Promotion GmbH (he/him), said: “Europe’s solar success has laid the foundation – now battery storage is stepping into its pivotal role. With solar power surging across the continent, the need for flexible capacity has never been clearer, and batteries are ready to deliver.

What is the European energy storage inventory?

A new interactive platform delivers real-time clean energy storage insights as Europe shifts toward sustainable energy sources. Energy storage helps to balance supply and demand. The European Energy Storage Inventory is the first of its kind at European level to show all forms of clean energy storage solutions.
