Czechia's largest battery, being built in Ostrava-Vítkovice, will be ready by year-end

The largest battery storage system in the Czech Republic, which ČEZ Group is building in Ostrava-Vítkovice, will be completed by the end of this year. Company spokesperson Vladislav Sobol told CTK today. The battery, which is as large as a family home, will have a capacity of almost ten megawatt-hours of energy—three times that of ČEZ's current largest battery in Tušimice in the Chomutov region.

The project is expected to cost around 100 million crowns. ČEZ aims to build new energy storage facilities with a capacity of 300 megawatts by 2030. The Ostrava battery is being built at the site of ČEZ Energetické služby in Ostrava-Vítkovice. Following demolition, the main construction work has now begun and is expected to be completed by the end of the year.

“The main construction work is now in full swing. It involves building retention tanks and foundations, creating new paved areas and relocating power cables from the decommissioned energy duct,” said Rostislav Díža, director of ČEZ Energetické služby.
