NHOA Energy has been awarded by ENGIE a contract for the supply, commissioning and long-term service of an 80 MW/320 MWh battery energy storage system (BESS) at ENGIE’s Drogenbos power station near Brussels. This installation, due to enter service in late 2027, will be ENGIE’s third large-scale battery asset in Belgium. Selected in the country’s fifth Capacity Remuneration Mechanism auction, the project carries a 15-year contract beginning November 2027 and underscores Belgium’s emphasis on procuring flexible resources to support energy security as renewable capacity grows.
The Drogenbos BESS will be based on NHOA Energy’s NHEXUS platform and consist of 88 battery containers capable of four hours of continuous discharge—equivalent to meeting the average daily electricity demand of approximately 38,000 households. By providing essential grid flexibility and stability services, the system will facilitate greater integration of wind and solar generation into Belgium’s national grid.
Construction is slated to begin in March 2026, with full commissioning expected by September 2027. Under a comprehensive Long-Term Service Agreement, NHOA Energy will deliver product and performance warranties alongside dedicated operation and maintenance services. Continuous monitoring and data-driven maintenance, supported by an established local structure, will ensure high availability levels and optimized performance throughout the asset’s lifecycle.
This award follows the ongoing construction of the 400 MWh Kallo BESS and reinforces NHOA Energy’s long-term commitment to the Benelux region’s energy transition. The project strengthens the strategic partnership between ENGIE and NHOA Energy, reinforcing both companies’ commitments to advancing utility-scale storage solutions and supporting Europe’s clean energy goals.
“With this new battery park, we are strengthening our current position as the Belgian reference in flexible energy generation and storage. It is no coincidence that flexibility is one of the three cornerstones of ENGIE’s strategy in Belgium, alongside renewable energy and smart customer solutions. 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 help us make optimal use of the available renewable energy.” commented Vincent Verbeke, CEO of ENGIE Belgium.
Lucie Kanius-Dujardin, Global Managing Director of NHOA Energy, highlighted the return to Drogenbos, where a pilot system was commissioned with ENGIE in 2018, and underscored the company’s role as a reliable partner in developing flexible and resilient power systems.
