CEZ Group is building Czechia's largest battery storage facility in Ostrava-Vítkovice

CEZ Group is building Czechia's largest battery storage facility in Ostrava-Vítkovice. The battery storage system will have a capacity of ten megawatts and store 9.45 megawatt-hours of energy, three times the capacity of CEZ's current largest battery in Tušimice in the Chomutov region. The battery, which is as large as a family house and will cost more than 100 million crowns to build, is intended to help stabilise the Czech power system. It is expected to be fully operational in the second half of this year. CEZ Group spokesperson Vladislav Sobol told the Czech News Agency today.

„The battery storage system will support the transformation of the Czech energy sector and help stabilise the power grid by providing ancillary services,“ the spokesperson said.

The large-scale battery at the Energocentrum Vítkovice site will operate in conjunction with a conventional power unit, which is a major regional energy supplier. The contractors are ČEZ Energetické služby, part of CEZ ESCO, and IBG Česko. It will be operated by ČEZ Energo, part of CEZ ESCO.
