ENGIE and NHOA Energy Begin Construction on 400MWh Battery Storage System in Belgium

ENGIE and NHOA Energy Advance Belgium’s Renewable Grid with 400MWh BESS

ENGIE and NHOA Energy have officially broken ground on a 400MWh Battery Energy Storage System (BESS) in Kallo, Beveren, Belgium. This marks a major milestone in Belgium’s efforts to strengthen grid reliability while supporting its transition to renewable energy.

The project follows ENGIE’s successful selection in the 4th Capacity Remuneration Mechanism (CRM) auction by Elia, Belgium’s transmission system operator. CRM was introduced to address energy shortages due to the expected partial phase-out of Belgian nuclear power plants in 2025. This battery system will play a critical role in ensuring grid stability during this transition.

Project Highlights and Energy Impact

ENGIE awarded the BESS supply contract and long-term service agreement to NHOA Energy. The groundbreaking ceremony included key figures such as Belgium’s Federal Minister of Energy Mathieu Bihet, Beveren Mayor Marc Van de Vijver, ENGIE Belgium CEO Vincent Verbeke, and NHOA Energy’s Global Managing Director Lucie Kanius-Dujardin.

The Kallo project will utilize NHOA Energy’s two decades of engineering experience in energy storage. Once completed, the system will deliver up to four hours of electricity—powering over 48,000 households. The site also repurposes the former Kallo power plant, which previously operated on natural gas and fuel oil before closing in 2011.

ENGIE’s Vincent Verbeke highlighted the collaborative nature of the project, stating that the new facility supports flexible energy capacity, enabling better integration of solar and wind power. Lucie Kanius-Dujardin emphasized the project’s significance in scaling battery storage across Europe to support a resilient and low-carbon energy system.

Driving Europe’s Energy Storage Future

This 400MWh project is ENGIE’s second large-scale battery park in Belgium and demonstrates the company’s commitment to renewable integration. It reflects a growing trend across Europe, where utility-scale battery systems play a vital role in balancing electricity supply and enhancing energy security.

SuperMetalPrice continues to monitor these developments, especially as they relate to critical materials like lithium, copper, and aluminum, which power the battery storage revolution. Projects like Kallo not only help modernize Europe’s grid but also highlight the strategic role of metal-intensive technologies in the clean energy transition.
