Located at the Dunamenti Power Station in Százhalombatta, MET previously established a 4 MW / 8 MWh demonstrator plant featuring Tesla Megapack 2 batteries in 2022. With the commissioning of this new BESS plant, MET Group and the Dunamenti Power Station are enhancing their role in Hungary’s energy transition. The combined storage capacity of all BESS units on site would be adequate to meet the entire decorative and public lighting requirements of Budapest for four hours. The equipment supplier is Huawei Technologies, while Forest-Vill Ltd serves as the project’s main contractor.

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.

Péter Horváth, CEO of the Dunamenti Power Station

Through its sustained investments in BESS projects across Europe, including the recent acquisition of French battery storage operator and developer Comax in 2024, MET Group is responding to the growing demand for balancing technologies essential for the energy transition. Additionally, MET is advancing technologically, making substantial investments in co-located storage facilities that are being developed alongside solar parks in various European nations.

Romanian division of ENGIE launches its first hybrid project in Europe

French energy group ENGIE has announced the development of its first hybrid energy project in Europe, co-locating wind energy generation with battery energy storage systems (BESS). The facility is being built in Băleni, Galați County, located in southeastern Romania.

The storage asset is being installed directly within ENGIE’s operational 50 MW Băleni wind farm, which has been active since 2013. The grid-connected battery will feature a power capacity of 5 MW and a storage capacity of 10 MWh, allowing it to deliver maximum electricity output to the grid for a continuous two-hour window. The unit is scheduled to be fully commissioned by the end of this year.
