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.
According to portfolio.hu, the project is estimated to cost HUF 8.5 billion (EUR 21 million), with a capacity of 60 MWh. Currently, Hungary’s entire energy storage capacity stands at 30 MW. The new storage battery is set to be operational by 2025, making it easier and more cost-effective to store renewable energy.
Hungary’s largest energy storage facility is currently under construction near Szolnok, with Chinese company Huawei involved in the solar energy project. The contract was signed in February, with MAVIR Ltd. as the investor. According to portfolio.hu, the project is estimated to cost HUF 8.5 billion (EUR 21 million), with a capacity of 60 MWh.
Hungary isn’t alone in stocking up on battery backup as it charts its green energy path. In neighbouring Bulgaria, a massive 124 MW/496 MWh battery energy storage system went live in Lovech earlier this year.
