MET Group has officially commissioned Hungary’s largest standalone battery energy storage system (BESS), marking a major milestone in the country’s journey toward a more resilient and renewable power grid. Located at the Dunamenti Power Station in Százhalombatta, the new facility boasts a capacity of 40 MW with 80 MWh of storage, capable of operating on a two-hour cycle.
The project is the latest in MET Group’s growing portfolio of battery storage investments across Europe. The group had previously installed a smaller 4 MW / 8 MWh demonstrator facility on the same site in 2022, utilizing Tesla Megapack 2 batteries.
This latest installation, which significantly expands the site’s energy storage capacity, has been designed to supply enough power to meet Budapest’s entire decorative and public lighting demand for approximately four hours. The main equipment supplier for the project is Huawei Technologies, with Forest-Vill Ltd. serving as the principal contractor.
During the inauguration event, Péter Horváth, CEO of Dunamenti Power Station, stressed the strategic importance of battery storage in enabling a cleaner energy mix. “Battery energy storage systems are essential tools for increasing the penetration of renewables into our power grid,” he said.
Péter Kaderják, President of the Hungarian Battery Association, echoed this sentiment, noting the need to fully leverage Hungary’s renewable energy potential through cost-effective and proven technologies. “The green energy transition remains a top priority in national energy policy, and this project is a clear step forward,” he stated.
This BESS launch is part of MET Group’s broader effort to build balancing and flexibility-enhancing technologies across Europe. The company’s 2024 acquisition of French battery storage firm Comax is one of several strategic moves to develop co-located storage with solar parks in multiple countries.
