Belgian investor to build Romania’s largest energy storage facility

In Ialomița County, eastern Romania, the Belgian company Aukera Energy will develop a large-scale Battery Energy Storage System (BESS) based on lithium-ion technology.

The facility will have a capacity of 150 MW / 300 MWh, capable of discharging at full power for two hours — making it the largest such battery project in Romania to date.

The project has secured €10 million in funding from Romania’s National Recovery and Resilience Plan (PNRR). Commissioning is scheduled by the end of 2026.

The site is strategically located in an area with significant wind power generation, designed to absorb excess renewable energy and stabilize the national grid.

Comment from the Institute of Danube Research

“The development of large-scale energy storage in the Danube–Black Sea macro-region is a milestone for the energy transition. For Romania, this project increases system flexibility and renewable integration. For Ukraine, it signals the emergence of regional energy balancing infrastructure that could, in the future, support cross-border cooperation.

Such investments open opportunities for Romanian–Ukrainian collaboration, especially in grid synchronization, renewable energy deployment, and storage solutions. Strengthening this energy resilience is crucial for the entire region.”
