4 Frequently Asked Questions about "Large-scale energy storage projects in Northern Europe"

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.

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.

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.

Is ore energy building Europe's largest Bess?

Netherlands-based iron-air long-duration energy storage (LDES) startup Ore Energy has completed a grid-connected pilot of its 100-hour iron-air LDES system at EDF Lab les Renardières in France. Owner-operator Fidra Energy came out of virtually nowhere to be building one of Europe's largest BESS in the UK, the 1.4GW/3.1GWh Thorpe Marsh project.
