MET Group has inaugurated Hungary’s largest standalone battery energy storage facility at the Dunamenti Power Station in Százhalombatta.
The 40MW/80MWh system, which operates on a two-hour cycle, is the latest in a series of MET investments across Europe and aims to support renewable energy integration into the Hungarian grid.
It follows the company’s earlier installation of a 4MW/8MWh demonstrator at the same site in 2022, based on Tesla Megapack 2 batteries.
The new facility is equipped by Huawei Technologies, with Forest-Vill Ltd serving as the main contractor.
Péter Horváth, chief executive of Dunamenti Power Station, said: “The application of battery energy storage systems is a key element on the road to energy transition, as they allow to increase the penetration of new renewable sources into the power grid.”
Hungarian Battery Association president Péter Kaderják added: “We must strive by all possible means to exploit Hungary’s renewable energy sources as extensively as possible, using well-established, cost-effective technologies.”
The combined storage capacity at the Százhalombatta site can meet the decorative and public lighting needs of Budapest for four hours, according to MET.
The Swiss-headquartered company is also expanding its BESS portfolio through acquisitions, including the 2024 purchase of French battery developer Comax.
MET is investing in co-located storage projects alongside solar parks in several European countries.
In 2024, MET Group reported sales revenue of €17.9bn, with traded volumes of 140 billion cubic metres of gas and 76TWh of electricity.
