Europe’s Largest Battery Storage Project Sees First Phase Activated by Sungrow and ENGIE

Amsterdam, September 30, 2025 – The first 400 MWh segment of mainland Europe's most extensive battery energy storage system (BESS) has been successfully connected to the grid in Vilvoorde, Belgium. This milestone was announced by Sungrow, a global leader in PV inverters and energy storage systems, which supplied 320 of its PowerTitan liquid-cooled storage units for this phase of ENGIE’s 200 MW/800 MWh initiative.

The project's second and final 400 MWh phase is scheduled for grid connection before the end of 2025. Upon full commissioning, the two-phase development is projected to significantly enhance grid reliability and supply clean electricity for approximately 96,000 households in Belgium.

"Battery storage is a pivotal, yet frequently undervalued, element for a successful shift to renewable energy. This undertaking showcases how our technology delivers the essential grid flexibility required for Europe's ongoing energy transition," stated Moritz Rolf, Vice President of Sungrow Europe. "Our effective collaboration with ENGIE on the Vilvoorde site underscores the vital function of large-scale storage in providing universal clean power and reaffirms our dedication to the European market."

A Milestone for Energy Infrastructure Modernization

The Vilvoorde project marks significant progress in the modernization of Europe's energy infrastructure, aligning with continental sustainability objectives for 2050. By storing excess energy during high generation periods and discharging it during peak demand, such large-scale BESS installations ensure a consistent and adaptable electricity supply from renewables. This project acts as a model for seamlessly incorporating green energy into existing grids, addressing congestion and improving balance.

Advanced BESS Technology in Focus

Both project phases are powered by Sungrow's PowerTitan units. These BESS solutions are designed with a compact footprint for rapid deployment and operational efficacy, key for large-scale infrastructure. The system's streamlined design maximizes land use and incorporates intelligently linked, liquid-cooled technology, promoting a temperature-regulated, economical, and dependable setup. These features ensure a secure and sustainable integration of massive energy storage into power networks.

"With the initial battery series now active in Vilvoorde, ENGIE is contributing crucial flexibility needed for grid supply-demand equilibrium. The park's efficient construction was made possible through robust partnerships. Aligning with innovative allies like Sungrow allows us to hasten the adoption of renewables and advance towards a more resilient, sustainable, and cost-effective energy framework," commented Vincent Verbeke, CEO of ENGIE Belgium.

Strengthened Local Engagement

Sungrow maintains a solid regional footprint in the BeNeLux area, with core offices and a research center in Amsterdam. A specialized team delivers technical support, sales, and after-sales services. The firm actively participates in key industry forums such as Intersolution and the Laadinfra congress, and organizes events like an EV Charging Summit in Amsterdam. This local engagement ensures prompt and efficient partner support, cementing its role in the region's renewable energy landscape.
