Energy storage system provider NHOA Energy and French electric utility Engie has agreed to partner in a new project to install a battery energy storage system (BESS) near Brussels, Belgium.
NHOA said it has been selected by Engie to supply, commission and service a new 80MW/320MWh BESS to be installed at the site of Engie’s Drogenbos power station.
The Drogenbos BESS will be Engie’s third large-scale battery asset in Belgium.
NHOA will install its NHEXUS platform, including 88 battery containers capable of providing up to four hours of discharge, corresponding to the average daily electricity demand of over 38,000 households.
Lucie Kanius-Dujardin, Global Managing Director of NHOA Energy, said: “With Drogenbos, we bring to the country another multi-hour storage system powered by our proprietary NHEXUS BESS platform and engineering expertise, reinforcing our position as a long-term partner for the development of flexible and resilient power systems.”
NHOA will also support the Drogenbos power plant with a long-term service agreement.
The company will guarantee high availability levels and optimised operational performance through the asset’s lifecycle.
The project expands the collaboration between NHOA and Engie, after the two worked together on an ongoing construction of the 400 MWh Kallo BESS, another flagship project for Belgium’s energy transition.
Vincent Verbeke, CEO of ENGIE Belgium, said: “With this new battery park, we are strengthening our current position as the Belgian reference in flexible energy generation and storage.
“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.”
The BESS project was selected in the fifth Capacity Remuneration Mechanism (CRM) auction by Belgian grid operator Elia, with its 15-year contract set to start running in November 2027.
The construction of the Drogenbos plant is scheduled to begin in March 2026, with full commissioning expected by September 2027.
