On the night of September 8, 2026, a large-scale power outage occurred in Ukraine's Mykolaiv and Kherson regions, affecting Mykolaiv, Kherson, and a number of settlements in both regions. According to Ukrenergo, around 20:00, electricity supply was simultaneously cut off across a significant portion of both regions' territory. The cause of the blackout was yet another attack by the Russian Armed Forces on energy infrastructure facilities. By 21:30, energy workers had completed the restoration work and restored power to consumers, taking less than two hours from the moment of the incident.
Timeline of the incident and speed of restoration
According to a statement by Ukrenergo, published on the company's official Telegram channel, as soon as the security situation on the ground allowed work to begin, energy crews started restoring the power supply. The promptness of their actions made it possible to restore electricity in most settlements of Mykolaiv and Kherson regions within approximately 90 minutes. The company emphasized that the restoration work was carried out under conditions of heightened threat and required strict coordination with military structures to ensure the safety of personnel.
Statements by regional authorities
Georgy Reshetilov, head of the Mykolaiv Regional Military Administration, who issued a clarification after the work was completed, confirmed that energy workers had promptly restored power to the region's residents. Earlier, at the height of the blackout, Yaroslav Shchanko, head of the Kherson City Military Administration, reported that at that time electricity was absent across the entire territory of the Kherson community. Thus, the sequence of statements reflects the dynamics of the situation: from a complete power outage in the city to the subsequent restoration of energy supply.
Scale of restoration work in August – early September
The incident in Mykolaiv and Kherson regions was part of a broader picture of damage to the power system that had accumulated over the past weeks. According to data previously published by RBC-Ukraine, from August 31 to September 6, DTEK energy workers restored electricity for nearly one million households in Donetsk, Odesa, Dnipropetrovsk, and Kyiv regions, which had been left without power as a result of Russian attacks. Over the entire month of August 2026, the total volume of restored capacity by DTEK in the four regions and Kyiv amounted to nearly 4.5 million homes. These figures bear witness to the systematic nature of the strikes on the energy sector and the continuous nature of the restoration work, which energy workers carry out in near real time.
Operational context and significance for consumers
The restoration of electricity in Mykolaiv and Kherson within an hour and a half after a large-scale blackout demonstrates the well-rehearsed action algorithms of energy services under combat conditions. For the residents of the two southern regions, where the absence of electricity affects water supply systems, communications, medical care, and heating, the speed of restoration is a critical factor. Ukrenergo and the relevant companies continue to monitor the state of the networks and are ready for repeat restoration work in the event of new damage to infrastructure.
