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
