Hungarian state-owned utility MVM is advancing the installation of a large-scale battery energy storage system at its gas-fired power plant in Ajka, as part of its strategy to enhance grid stability.
The planned facility will have a rated output of 57 MW and is expected to be completed by the end of June. The total investment exceeds €27 million, with around €10 million provided through EU support under Hungary’s Recovery and Resilience Plan.
MVM says the new battery will be able to deliver full output within seconds, helping to offset electricity system volatility, especially fluctuations linked to weather-dependent renewable generation.
The Ajka project follows a similar development at MVM’s Tiszaujvaros site, also partly funded by the EU. Beyond storage, MVM plans a broader expansion of conventional capacity, targeting 1,600 MW of new gas-fired electricity generation across Hungary in the coming years.
