NHOA Energy has secured a major contract from ENGIE for the supply, commissioning and long-term maintenance of a 80 MW / 320 MWh Battery Energy Storage System (BESS). The project will be installed at ENGIE’s Drogenbos power station near Brussels, with construction set to begin in March 2026 and full commissioning expected by September 2027.
A project supported by the capacity remuneration mechanism
The Drogenbos system was selected in Belgium’s fifth Capacity Remuneration Mechanism (CRM) auction and secured a 15-year contract starting in November 2027. It is ENGIE’s third large-scale storage asset in the country. The BESS, based on NHOA Energy’s proprietary NHEXUS platform, will include 88 battery containers capable of delivering up to four hours of discharge, equivalent to the average daily electricity consumption of over 38,000 households.
Strengthening industrial presence in Belgium
The project further reinforces NHOA Energy’s presence in the Benelux markets, following the ongoing construction of the 400 MWh Kallo plant. It also highlights the strategic value of the Drogenbos site, where the two companies had already collaborated on a pilot system in 2018.
Long-term service agreement to optimise performance
After commissioning, NHOA Energy will operate the plant under a long-term service agreement, combining product and performance warranties with comprehensive operations and maintenance services. The system will rely on real-time monitoring and data-driven maintenance, supported by local infrastructure, to ensure high availability and optimised performance throughout the asset’s lifecycle.
ENGIE positions flexibility as a strategic pillar
ENGIE considers system flexibility a core element of its strategy in Belgium, alongside renewable energy and smart customer solutions. The company continues to strengthen its position as a key player in flexible energy management on the Belgian market, with increasing storage capacity aimed at supporting national grid stability.
