Engie kicks-off 800MWh Belgian battery build

July 10, 2024

ENGIE has began construction of “one of Europe’s largest” battery energy storage systems (BESS), a 200MW / 800MWh project at its Vilvoorde site in Belgium.

BESS Vilvoorde will store energy in 320 battery modules measuring 25 metres by 4 metres by 3 metres and will meet the electricity consumption needs of 96,000 households. The battery park has a 15-year contract with Elia, the Belgian national grid operator.

BESS Vilvoorde will be launched in two phases, with the commissioning of 100 MW of batteries in September 2025, and a further 100 MW in January 2026. ENGIE is also developing two other BESS projects in Belgium for which the Group has already obtained permits, at Kallo (100MW / 400 MWh) and Drogenbos (80MW / 320 MWh).

Sébastien Arbola, executive vice president in charge of Flex Gen & Retail activities at Engie, said: “With the growing share of renewable energies in the energy mix, the contribution of battery energy storage systems to ensuring the reliability and security of energy systems is becoming crucial. Batteries will enable the absorption of peaks in renewable energy production, and the release of this energy when production is lower and consumption higher. These flexibility solutions will thus help accelerate the development of renewable energies and the energy transition.”
