Ukrenergo shows house-sized crater after Russian strike on substation

Ukraine's state energy company Ukrenergo reported that a Russian strike on one of its substations left a crater the size of a house, as Moscow has intensified attacks on the country's energy infrastructure this year. Russia has shifted tactics to launch round-the-clock assaults on key energy facilities using drones and ballistic missiles. Repeated strikes are destroying equipment before repairs can be completed, though protective structures help limit damage, according to the company. Despite the ongoing attacks, repair crews are working around the clock to restore damaged objects and maintain grid balance. New power outages were reported in nine Ukrainian regions on Thursday, and four energy workers were wounded in the Poltava region.
