Technical FAQs 4

What is the largest battery storage project in Belgium?

Construction has started on what will be the largest battery storage project in Belgium at 25MW/100MWh when completed later this year. Nala Renewables’ lithium-ion battery energy storage system (BESS) will come online at metals conglomerate Nyrstar’s zinc smelting operation in Balen, in Belgium’s Flemish region, by the end of 2022.

What is the energy storage project in Belgium?

The main energy storage project in Belgium is the construction and operation of an offshore “energy atoll” (essentially a manmade offshore pumped-storage facility), for which the Electricity Act has been modified in 2014 (see below), in order to support offshore wind-generated electricity production.

Why are battery storage projects taking off faster in Belgium?

Battery storage projects in Belgium have taken off quicker than in the rest of mainland Europe thanks to more storage-friendly market rules. The market has some strong drivers for storage including a lack of grid flexibility and good interconnection with other markets.

Where is Europe's largest battery energy storage system located?

Engie and Sungrow have commissioned the first 400 MWh phase of mainland Europe’s largest battery energy storage system in Vilvoorde, Belgium, with full capacity due by end-2025.
