Belgium's Largest Operational Battery Asset Goes Live

EDF subsidiary Luminus and infrastructure fund I4B have officially commissioned the Navagne battery energy storage system (BESS) located in Lixhe, Belgium. Boasting a capacity of 150 MW and 600 MWh, the facility represents a significant milestone for the Belgian energy transition. Backed by a substantial €160 million capital investment, Navagne stands as the largest operational battery asset in the region, marking a major step forward in the country's decarbonization and grid modernization efforts.

Technical Specifications and Grid Integration

The 600 MWh Navagne facility features a four-hour dispatch duration. This configuration reflects a growing regional trend in the Benelux area towards deeper energy shifting, wholesale arbitrage, and capacity provision. To achieve this scale, the project-level capital expenditure was approximately €266.7 per kilowatt-hour. The system utilizes advanced Sungrow battery models, with 132 storage containers installed on-site to deliver the massive four-hour discharge capability required by the market.

Navagne connects directly to transmission system operator Elia’s high-voltage network, allowing it to provide critical grid-support services, manage congestion, and stabilize the local electricity supply during periods of high renewable generation or peak demand.

Financial Close and Future Outlook

The project successfully reached financial close in June 2025, paving the way for rapid construction and deployment. The commissioning of Navagne not only enhances grid flexibility in Belgium but also demonstrates the commercial viability of large-scale, standalone battery investments in the European market. As the Benelux region continues to integrate higher shares of intermittent renewable energy, massive assets like Navagne will be absolutely crucial for managing variability, ensuring reliable power delivery, and maintaining overall system stability across the interconnected European grid.
