Swiss-based energy firm MET Group has officially commissioned Hungary’s largest standalone battery energy storage system (BESS), marking a major step forward for the country’s renewable energy infrastructure. Located at the Dunamenti Power Station near Budapest, the new facility has a total output of 40 megawatts (MW) and a storage capacity of 80 megawatt-hours (MWh).
The project represents a significant expansion of MET Group’s presence in Hungary’s clean energy sector and follows the successful deployment of a smaller 4 MW / 8 MWh BESS pilot in 2022. That demonstrator system, also located at the Dunamenti site, utilizes Tesla Megapack 2 battery technology.
“Battery storage is a vital element in the transition to a stable, low-carbon energy grid,” said MET Group representatives at the inauguration. “This new installation reinforces our commitment to building a more resilient and flexible power system in Central and Eastern Europe.”
Originally a coal and gas power station, the Dunamenti site has undergone a steady transformation since MET Group acquired a 75% stake from GDF Suez in 2014. The energy company has since integrated solar photovoltaic systems and now, with the latest battery infrastructure, is establishing the site as a key hub for renewable energy innovation.
The standalone BESS will help balance Hungary’s increasingly variable renewable energy supply and support grid stability as the country moves away from fossil fuels.
