Met Group has inaugurated Hungary's largest standalone battery energy storage system (BESS), a 40 MW / 80 MWh facility located at the Dunamenti Power Station in Százhalombatta. The project marks a significant step in the country's energy transition, providing key infrastructure to support renewable energy integration.
The new system, capable of storing and discharging electricity over a two-hour cycle, builds on an earlier 4 MW / 8 MWh demonstrator plant installed by Met in 2022. Together, the facilities have enough capacity to power all decorative and public lighting in Budapest for four hours. The project was delivered with equipment supplied by Huawei Technologies and constructed by Forest-Vill Ltd.
“The application of battery energy storage systems is a key element on the road to energy transition,” said Péter Horváth, CEO of Dunamenti Power Station. “They allow for greater penetration of renewable energy into the power grid.”
Péter Kaderják, President of the Hungarian Battery Association, added: “Hungary must exploit its renewable energy sources using proven, cost-effective technologies. We support all initiatives aligned with the country's green energy goals.”
The Dunamenti project is part of Met Group's broader strategy to invest in energy storage across Europe. The company recently acquired French battery storage developer Comax and is expanding its portfolio of co-located battery and solar energy facilities. With operations in 17 countries and €17.9 billion in revenue in 2024, Met Group is positioning itself as a key player in Europe's energy transition.
