A new energy storage complex has been launched in Ukraine, specifically in the Kyiv and Dnipropetrovsk regions, capable of supplying electricity to 600,000 households for two hours.

This was reported by the Ministry of Energy.

“Ukraine has commenced operations of its largest energy storage complex with a capacity of 200 MW, built by DTEK in partnership with the American company Fluence Energy B.V. The complex consists of six facilities constructed in a record time of just one year. Investments in the project totaled 125 million euros,” the report states.

It is noted that the complex can store 400 MWh of electricity, sufficient to meet the needs of 600,000 homes over a two-hour period.

“The new facilities enhance the reliability and flexibility of the system, reduce the risks of emergency outages, and allow for effective preparation for the winter. This also opens up new opportunities for the development of renewable energy and the decentralization of the energy system,” commented Energy Minister Svitlana Hrynchuk.

Thus, storage systems provide Ukraine with additional capabilities for balancing the energy system and regulating frequency, which is particularly important given the increasing share of renewable sources and ongoing challenges due to the war.

The Market Operator JSC will begin testing a platform on October 7, 2025, which will allow for the assessment of the economic viability of energy storage systems across different market segments. According to forecasts from NEC “Ukrenergo,” in the next 10 years, the Ukrainian energy system will require 1.5 GW of energy storage capacity.
