Sungrow has commissioned the first 400MWh of ENGIE’s 200MW/800MWh battery energy storage system (BESS) in Vilvoorde, Belgium — the largest such facility in mainland Europe. The feat is a significant step forward for the region’s grid flexibility and integration of renewables.
The project employs 320 units of Sungrow’s PowerTitan liquid-cooled battery storage systems. Upon completion of the second 400MWh phase by the end of 2025, the entire installation will be providing clean, stable power for about 96,000 homes and helping stabilize Belgium’s power grid.
Battery storage is one of the most vital, yet too often overlooked, pieces of the energy transition jigsaw,” said Moritz Rolf, Sungrow Europe Vice President. “Our partnership with ENGIE on Vilvoorde demonstrates how our solutions deliver the grid flexibility that will underpin Europe’s renewable future.”
Strengthening Europe’s Energy Backbone
The Vilvoorde project is a big step forward in updating Europe’s energy infrastructure for the modern age. While this marks a major milestone, several other large-scale battery energy storage projects are also under development across the continent, signaling rapid momentum in the sector. By absorbing surplus energy when renewable production peaks and feeding it into the grid during high demand, the facility stabilizes the grid and reduces network congestion — an increasing challenge as Europe accelerates its decarbonization push toward 2050.
ENGIE’s solution illustrates the incorporation of large-scale BESS into existing grids with clean energy, as a blueprint for future grid modernizations across the region.
Technology Built for Safety and Scale
Sungrow’s PowerTitan solution is the foundation for both phases of the project. The system features a compact, modular design that’s well-suited for rapid deployment and optimized land use efficiency. Its liquid-cooled, temperature-controlled technology optimizes operational reliability while reducing maintenance and lifecycle costs — considerations critical to utility-scale storage.
“With the first series of batteries in operation, ENGIE is delivering part of the flexibility the grid needs to balance supply and demand,” said Vincent Verbeke, Managing Director of ENGIE Belgium. “This success can only be achieved through collaboration with solid partners like Sungrow.”
Growing Local Presence
Sungrow is strengthening its foothold in the BeNeLux market. The company operates offices and an R&D center in Amsterdam. Local teams handle technical support, sales, and after-sales services. This ensures close collaboration with partners such as ENGIE.
Sungrow also takes part in major regional events, including Intersolution and the Laadinfra Congress. Recently, it hosted an EV Charging Summit in Amsterdam, highlighting its expanding role in Europe’s clean energy ecosystem.
