Russian forces attacked warehouses of Ukraine's largest private energy company DTEK in Dnipropetrovsk Oblast on Oct. 2, causing damage to cables, transformers, and other electrical equipment, the company said on the Telegram messaging app.
The company did not specify the extent of the damage, nor the time and resources it would require to repair it.
"No matter how hard the enemy tries," DTEK wrote, "they will not be able to disrupt our preparations for the winter season."
Russia has repeatedly attacked critical infrastructure across Ukraine since early October 2022, killing dozens of people and causing mass power outages across the country.
Moscow has admitted that Ukraine's energy system is one of its primary targets. According to the Geneva Convention, attacking vital public infrastructure constitutes a war crime.
President Volodymyr Zelensky said on Sept. 9 that there were plans in place to protect Ukraine's energy and critical infrastructure from Russian missile and drone strikes through the winter.
Earlier on Oct. 2, German Foreign Minister Annalena Baerbock emphasized the need for Ukraine's allies to increase the strength of a "winter protection umbrella" in order to alleviate the disruptions associated with the Russian military's attacks on Ukrainian critical infrastructure.
