ENGIE & NHOA Energy Broke Ground on Its 320MWh Belgium BESS

ENGIE and NHOA Energy broke ground on a 320MWh battery energy storage system at ENGIE’s Drogenbos power station near Brussels. The project was awarded in Belgium’s fifth Capacity Remuneration Mechanism auction and includes a 15-year contract beginning in November 2027. The Belgium grid battery energy storage project includes 88 battery containers providing up to four hours of discharge, covering the average daily electricity use of more than 38,000 households. It is managed through NHOA Energy’s NHEXUS and PROPHET control platforms.
The project is ENGIE’s third large-scale battery initiative in Belgium, alongside the 400MWh Kallo BESS currently under construction, supporting ENGIE’s target of 500MW of battery storage in Belgium by 2030.
ENGIE and NHOA Energy show how pairing long-term capacity contracts with purpose-built control platforms can make large-scale battery storage a commercially viable and grid-critical infrastructure investment.
