Hungary’s state-owned energy group MVM has commissioned a 31 MW / 62 MWh battery energy storage facility in eastern Hungary. The project received approximately HUF 4 billion (€10 million) in European Union funding through Hungary’s Recovery and Resilience Facility.
The new battery installation, located in Tiszaújváros, forms part of MVM’s broader strategy to increase grid flexibility, improve the integration of renewable electricity and strengthen Hungary’s energy security.
Building an energy hub
The battery facility is located alongside one of Hungary’s largest ongoing energy projects, a new combined-cycle gas turbine (CCGT) power plant with planned capacity of around 1 gigawatt.
Together, the gas-fired plant and the battery storage system are expected to create a highly flexible generation hub capable of responding to fluctuations in renewable electricity production while supporting overall grid stability.
Battery storage allows surplus electricity generated during periods of strong sunshine to be stored and released later, reducing pressure on the transmission network and helping maintain system stability during periods of lower renewable output.
Storage portfolio continues to grow
Following the commissioning of the Tiszaújváros project, MVM’s battery storage portfolio has reached 124 MW with a total energy storage capacity of 215 MWh. The company expects installed battery capacity to increase to 141 MW before the end of 2026.
Looking further ahead, MVM plans to expand its battery fleet to approximately 500 MW by 2030, positioning energy storage as one of the central pillars of Hungary’s energy transition strategy.
