ENGIE will start building an 80MW/320MWh battery at Drogenbos in Flemish Brabant in March 2026 with completion slated for September 2027.
The project secured a 15-year capacity contract from November 2027 in Elia’s fifth Capacity Remuneration Mechanism auction announced on 30 October 2025.
The Drogenbos scheme will comprise 88 battery modules able to deliver for four hours, equivalent to 64,000 5kWh home batteries or the average daily electricity use of 38,400 households.
It is ENGIE’s third large-scale Belgian storage project after Vilvoorde at 200MW/800MWh and Kallo at 100MW/400MWh, taking the portfolio to 380MW and 1.5GWh.
“With this new battery park, we are strengthening our current position as a Belgian reference in the field of flexible energy production and storage,” said ENGIE Belgium chief executive Vincent Verbeke.”It is no coincidence that flexibility is one of the three cornerstones of ENGIE’s strategy in Belgium, along with renewable energy and smart customer solutions,” said Verbeke.
“The flexible storage capacity of batteries will play a key role in tomorrow’s energy system: by balancing supply and demand, they support the electricity grid and enable us to make the most of the available renewable energy,” said Verbeke.
