HybriX Energy Achieves Financial Close on Two 35MW Grid-Scale Battery Storage Projects

 Belgium, 17/04/2026 – HybriX Energy, a Belgian pure-play developer dedicated to grid-scale battery energy storage systems (BESS), today announced that it reached financial close at the end of March on two large-scale battery storage projects located in Geel and Massenhoven. Named “Volta” and “Franklin”, the projects pay tribute to Alessandro Volta and Benjamin Franklin - pioneers in the early discovery and understanding of electricity and batteries. 

Each project will have a capacity of 35MW with 4 hours of storage duration, marking a significant milestone in strengthening Belgium’s energy resilience amid ongoing market volatility and the broader European energy crisis. 

As part of the transaction, HybriX Energy secured senior debt financing from leading Belgian financial institutions BNP Paribas Fortis and Belfius. The financing highlights continued lender confidence in grid-scale storage as a key enabler of the energy transition, as well as strong domestic support for strategic energy infrastructure. 

Construction works on both sites have already commenced, with project completion targeted for 2027. Once operational, the two battery systems combined will deliver 300 MWh of storage capacity, equivalent to the average daily electricity consumption of approximately 30,000 Belgian households. The installations will provide essential grid flexibility, support the integration of renewable energy sources, and contribute to stabilizing electricity supply during peak demand periods.

“Hitting financial close on these projects is a defining moment for HybriX Energy,” said Kevin Lammertyn, Co-Founder and CEO of HybriX Energy. “It confirms both the strength of our team and pipeline and the growing recognition that grid-scale storage is critical infrastructure in today’s energy system.”

“Our focus has always been on developing high-quality, grid-scale BESS assets that deliver real system value,” added Stijn Heyselberghs, Co-Founder and CDO of HybriX Energy. “With construction already underway in Geel and Massenhoven, we are proud to contribute concretely to Belgium’s energy transition and security of supply.”

The financial close of these two projects represents another step forward in HybriX Energy’s mission to build a more resilient, sustainable and future-proof energy system.

Supporting Belgium’s security of supply through CRM 

Both projects have previously been successfully awarded 15-year capacity contracts under Belgium’s Capacity Remuneration Mechanism (CRM), operated by Elia, which ensure security of supply for the coming delivery years and highlight the growing role of battery storage in the Belgian energy mix. 

The CRM framework provides long-term revenue visibility for capacity providers while ensuring that sufficient flexible resources are available to maintain grid reliability, particularly as Belgium continues its energy transition. 

As Europe continues to navigate an evolving energy landscape marked by supply constraints and increasing renewable penetration, battery energy storage systems are becoming indispensable. Grid-scale BESS projects enable more efficient use of renewable generation, reduce curtailment, and enhance grid reliability—key factors in addressing both short-term energy security concerns and long-term decarbonization goals.
