Sungrow & ENGIE Complete First 400 MWh of Europe’s Largest Battery Storage Project
On 30 September 2025, Sungrow and ENGIE announced a milestone: the first 400 MWh segment of the Vilvoorde battery storage project in Belgium is now successfully connected to the grid. This is part of what is projected to become one of Europe’s largest battery energy storage systems (BESS) on the mainland. (Sungrow Power)
Project Overview
- The full project is designed for 200 MW / 800 MWh capacity, to be completed in two phases. (Sungrow Power)
- The first phase (400 MWh) uses 320 units of Sungrow’s PowerTitan liquid-cooled battery systems. (Sungrow Power)
- The second phase (remaining 400 MWh) is scheduled to be grid-connected before the end of 2025. (Sungrow Power)
- The site is located in Vilvoorde, Belgium. (Sungrow Power)
Technical & Strategic Significance
The Vilvoorde BESS project is strategically important:
- It will support grid stability by absorbing surplus power and supplying energy during high demand periods. (Sungrow Power)
- It can serve up to 96,000 households with clean, flexible energy across Belgium. (Sungrow Power)
- The modular PowerTitan units are optimized for compact land use, temperature control, and efficient deployment. (Sungrow Power)
- This project demonstrates Sungrow’s capabilities in large-scale BESS integration, especially in collaboration with major energy firms like ENGIE.
Partnership & Market Implications
This collaboration between Sungrow and ENGIE emphasizes the growing importance of energy storage in Europe’s energy transition.
- It strengthens Sungrow’s position in the Benelux / DACH region by showcasing scale and reliability.
- It provides a blueprint for how utility-scale storage can be financed and executed without disrupting existing grid systems.
- The success may catalyze more BESS projects, especially where renewable penetration is high and grid balancing is critical.
Outlook & Next Steps
- The second half of the project (remaining 400 MWh) is expected to connect by year end 2025. (Sungrow Power)
- Operational data and system performance will be closely watched as benchmarks for future projects.
- This success could attract further investments for storage in neighboring regions and countries.
Conclusion:
With the first 400 MWh now live, the Vilvoorde project stands as a landmark in European battery deployment. Sungrow & ENGIE have proven that large-scale BESS can be realized at speed and scale, paving the way for a more flexible, reliable renewable grid future.
