Battery systems

In Belgium, ENGIE plays a leading role in the transition to a low-carbon future. In doing so, in addition to renewable energies, energy storage has an important role to play.

This is because renewable energy production is intermittent. This means that when there is a lot of sun or wind, they sometimes produce too much electricity or, when there is not enough sun or wind, too little electricity to meet demand. This can lead to overloading of the electricity grid or shortages of generation during peak demand periods. This is because the grid must constantly and instantly balance production and consumption. This task becomes increasingly difficult as the share of renewable generation capacity increases. 

Battery Energy Storage Systems (BESS) can support the grid and help meet the growing need for flexibility. They do this by absorbing peaks in (renewable) energy production, storing the energy and releasing it when the (renewable) energy production is lower.

As a leading producer of green energy in Belgium, ENGIE also wants to take the lead in this field by developing battery projects. This is why ENGIE has submitted 3 permit applications for the creation of battery parks. 

For which sites have the permit applications been submitted?

Drogenbos site - 80 MW 
Kallo site - 100 MW 
Vilvoorde site - 200 MW

ENGIE commissions first half of the Vilvoorde battery park

ENGIE has officially started commercial operation of the first 100 MW/400 MWh of its battery park in Vilvoorde. Once the second half is completed by the end of the year, the entire 200 MW/800 MWh installation will be one of the largest battery energy storage systems (‘BESS’) in Europe. This landmark project enhances the integration of renewable energy sources into Belgium's energy system, and reinforces its resilience.

First spade in the ground marks start of construction for ENGIE’s new battery park in Vilvoorde

Today, on 5 July 2024, a ground breaking celebration in the presence of mayor Hans Bonte marked the start of the construction of a new 200 MW battery park on the ENGIE site in Vilvoorde. From September 2025, the batteries will be available to store 800 MWh of electricity and inject it into the grid for up to four hours. This type of flexibility, one of ENGIE's strategic priorities, will provide essential support to the power grid.
