ENGIE And NHOA Energy Begins Construction of 400 MWh Battery Storage Project In Belgium

NHOA Energy, a global provider of large-scale energy storage systems, has officially begun construction of a 400 megawatt-hour battery energy storage system (BESS) in Kallo, Beveren, Belgium, in partnership with ENGIE. The project will be delivered under a supply contract and long-term service agreement between the two companies. A groundbreaking ceremony was held to mark the start of construction, with key figures in attendance including Belgium’s Federal Minister of Energy Mathieu Bihet, the Mayor of Beveren Marc Van de Vijver, ENGIE Belgium CEO Vincent Verbeke, and NHOA Energy’s Global Managing Director Lucie Kanius-Dujardin.

This battery project follows ENGIE’s selection in the fourth Capacity Remuneration Mechanism (CRM) auction organized by Belgian grid operator Elia. The CRM was introduced by the Belgian government to help secure the country’s future energy needs, especially as Belgium plans to partially phase out its nuclear power by 2025. The Kallo site, once home to a power plant that ran on gas and fuel oil before closing in 2011, will now support the country’s energy transition through advanced storage technology.

Vincent Verbeke, said, “It is with great pride that we are launching the construction of this battery park in Kallo today, together with the Minister of Energy, the municipality, and our valuable partners. This is ENGIE’s second large-scale park in Belgium, a project that can only be realized through close cooperation with all of them. By developing this additional flexible capacity, we are contributing to the optimal use of wind and solar energy and meeting the needs of the electricity grid.

“We are proud to once again join forces with ENGIE, reinforcing our mutual dedication to expanding battery energy storage solutions across Europe. This partnership to support the Belgian grid operator, Elia, underscores the essential role of energy storage in enabling the transition toward a more sustainable and resilient energy system,” mentioned Lucie Kanius-Dujardin.

NHOA Energy brings nearly 20 years of experience in energy storage, with strong European expertise in power electronics and engineering. The Kallo BESS is designed to deliver electricity for up to four hours and will be capable of powering more than 48,000 households. The system will also feature high standards of performance, cybersecurity, and resilience to support Belgium’s growing renewable energy infrastructure.
