Technical FAQs 4

Where is Hungary's largest battery energy storage system located?

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.

Will Hungary's new battery energy storage system help Green the grid?

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.

How much power does met have in Hungary?

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.

How will Hungary's subsidy scheme affect battery energy storage?
