A new battery energy storage facility has officially entered operation in the southern Hungarian city of Baja, further strengthening the country’s expanding renewable energy infrastructure.
The project was developed by local company Merital Vagyonkezelo and features a storage system with a total capacity of 3 MWh, representing an investment of approximately €1.55 million. The facility has been integrated with an existing solar power plant at the same site, which has an installed capacity of 1.8 MW.
The system is designed to store excess solar electricity during periods when grid injection is restricted, helping to improve overall efficiency and utilization of renewable generation. By capturing surplus output, the installation reduces waste and supports more stable energy delivery.
Beyond solar integration, the facility will also participate in Hungary’s balancing energy market, specifically within the automatic frequency restoration reserve (aFRR) segment. This allows it to contribute to grid stability by responding to short-term fluctuations in electricity supply and demand.
A portion of the project’s financing was provided through Hungary’s Recovery and Resilience Plan, under which it received around €600,000 in non-refundable EU funding, highlighting continued support for energy transition investments in the region.
