HELLENiQ ENERGY launches major battery storage facility in Thessaloniki

HELLENiQ Renewables, a subsidiary of HELLENiQ ENERGY, has officially completed and commissioned its first large-scale battery energy storage system (BESS) at the company’s industrial site in Thessaloniki, Greece. This infrastructure project represents an investment of approximately 50 million euros and stands as one of the largest electricity storage installations in both Greece and Southeast Europe.

The facility features an installed power capacity of 100 MW and a total storage capacity of 200 MWh. It is designed to enhance the efficiency of renewable energy utilization by capturing excess power generated from renewable sources that would otherwise be curtailed when supply exceeds instantaneous demand. The stored energy is sufficient to charge roughly 3,000 electric vehicles daily, providing critical flexibility and balancing services to the national electricity transmission system, thereby increasing grid resilience and national energy security.

This development marks a strategic shift for the group as it expands its operations beyond traditional renewable electricity generation into specialized infrastructure. The project is part of a broader regional expansion strategy, with HELLENiQ ENERGY currently developing a portfolio of storage projects exceeding 1 GW across Greece, Romania, Cyprus, and Bulgaria.
