A key Russian substation, Veshkaima, burned down in the Ulyanovsk region.

Russia has lost the Veshkaima substation (500 kV) in the Ulyanovsk region – one of the key elements of its power system.

The head of the Center for Countering Disinformation under the National Security and Defense Council, Andriy Kovalenko, reported this on Telegram .

According to him, the substation provided a connection between the Ulyanovsk, Mordovia, Chuvashia, and Samara regions and served as a transit hub for transmitting electricity from the Syzran and Zhigulevskaya hydroelectric power plants to the central regions of Russia.

“This is what happens when you hit Ukraine’s energy sector,” Kovalenko emphasized.

The Veshkaima substation is considered a key facility in the Russian power grid, connecting several major industrial regions of the Russian Federation.

It was previously reported that the operation to destroy part of the refinery’s facilities was carried out by Ukrainian Special Operations Forces jointly with the Black Spark rebel movement . This is the third time this year that the Kirishi refinery has been attacked. Each time, the consequences for Russian oil refining are becoming increasingly painful.

As a reminder, Ukrainian drones caused record damage to Russia’s oil refining industry, knocking out nearly 38% of primary oil refining capacity.

On October 2 , powerful explosions were heard in Russia’s Perm Krai : drones struck a branch of the Uralchem plant’s Azot plant in the city of Berezniki, located 1,700 km from the Ukrainian border.

Earlier, SBU drones struck Russia’s largest oil terminal, Primorsk, in the Baltic Sea, halting oil shipments.
