MET Group inaugurates Hungary’s largest battery energy storage system
MET Group installed a battery energy storage system of 40 MW and a two-hour duration at its gas power plant Dunamenti near Budapest. The company said it is the largest BESS in Hungary.
Hungary’s largest standalone battery energy storage system (BESS) has been inaugurated today. MET Group put into operation a facility of 40 MW in nominal operating power and a two-hour cycle, translating to 80 MWh in capacity. The Switzerland-based company said it is part of a series of its investments in BESS throughout Europe.
MET already installed a 4 MW / 8 MWh demonstrator unit in 2022, also at its gas-fired Dunamenti Power Station in Százhalombatta, in Pest county. It is based on Tesla Megapack 2 batteries.
The combined capacity would be sufficient to supply the entire decorative and public lighting needs of Budapest for four hours, the energy company pointed out. The supplier of the new equipment is Huawei Technologies and the main contractor is Forest-Vill, MET Group added.
BESS is essential for energy transition
Battery energy storage systems are a key element for the energy transition, as they allow greater penetration of renewable sources into the power grid, Dunamenti’s Chief Executive Officer Péter Horváth said at the inauguration ceremony.
“We must strive by all possible means to exploit Hungary’s renewable energy sources as extensively as possible, using well-established, cost-effective technologies. Therefore, the Hungarian Battery Association supports the efforts of the Hungarian energy policy, which deals with the green energy transition as a top priority,” the association’s President Péter Kaderják stated.
MET Group investing in batteries colocated with solar power plants
MET Group said that with its ongoing investments in BESS projects across Europe, it aims to address the increasing need of balancing technologies to support the energy transition. The company acquired French battery storage operator and developer Comax in 2024.
A significant part of the investments is for storage facilities colocated with solar parks, the update reads.
MET is present in 17 countries, 32 national gas markets and 44 international energy trading hubs. It has more than 1,100 employees. The company’s consolidated sales revenue amounted to EUR 17.9 billion last year, with a total traded volume of natural gas amounting to 140 billion cubic meters and total traded electricity of 76 TWh.
