Videos circulating on social media show a drone striking the electrical substation in the village of Energetik and sparking a large fire.
The Vladimir substation, rated at 750 kV, is one of the largest and most powerful in Europe. It is a strategic node in Russia’s Unified Energy System, supplying power to the Central Federal District, including Moscow, Vladimir, Nizhny Novgorod, and parts of the Ivanovo oblast.
In Yaroslavl, residents heard multiple explosions near the Slavneft-YANOS refinery. Other social media reports suggested that the Yaroslavnefteorgsintez refinery, located nearby, may have been targeted as well.
In response to a drone attack alert, the Russian Federal Aviation Authority (Rosaviatsia) imposed temporary flight restrictions at Yaroslavl Airport.
Earlier in the day, local authorities confirmed that the Oryol Thermal Power Plant had also been attacked by drones, damaging regional power supply systems.
