The 2-hour battery energy storage system (BESS) is the largest in Hungary, Switzerland-headquartered MET Group said, deployed at its Dunamenti thermal power plant in Százhalombatta, near Budapest.
The new facility supports a growing push to green Hungary’s power grid. Hungary has just switched on its largest battery energy storage system (BESS) to date, stepping up its role in Central Europe’s growing grid-scale energy transition.
MET Group has switched on Hungary’s largest battery, a 40 MW/80 MWh system, at the site of a power station near Budapest. From ESS News Swiss-based energy company MET Group has officially inaugurated Hungary’s largest standalone battery energy storage system (BESS) at its Dunamenti Power Station in Százhalombatta, located close to Budapest.
The new facility boasts a total power output of 40 MW and a storage capacity of 80 MWh. This project significantly expands MET Group’s energy storage portfolio in Hungary. It joins a smaller 4 MW / 8 MWh demonstrator BESS, which utilizes Tesla Megapack 2 batteries and was installed at the same site in 2022.
In future developments, innovations in energy storage technologies will further enhance their role in the energy transition. For instance, improving the energy density of battery containers is an important direction in the development of current battery technologies.
Although energy storage technologies still face certain challenges in terms of cost, efficiency, and large-scale application, with ongoing research and development and increased policy support, the future development prospects of energy storage technologies are vast.
