Russian state corporation Rostec has announced the start of serial production of mobile electrical substations, describing the systems in a Telegram post as an “energy ambulance” for blackout scenarios.
The complexes, developed with the participation of RT-Project Technologies, are mounted on wheeled platforms, including off-road trailers. They support various voltage classes and are adapted for operation in any climate. Rostec claims the solution allows power supply to be restored immediately upon arrival at the site.
The corporation explicitly noted that such systems are especially relevant “amid the risk of large-scale outages as a result of drone attacks.” According to specialists’ calculations, having two to four mobile substations in a region’s balance can cover any emergency need. The complexes are also planned for use during scheduled repairs and reconstruction of stationary energy facilities.
Ukrainian drones regularly damage power grids in Russia’s border regions, most often in Belgorod Oblast. In the first 10 months of 2025, according to Novaya Gazeta Europe’s calculations, drone attacks caused 467 cases of damage to power grids. By mid-November last year, more than 4,000 accidents had occurred at Russian energy facilities, with one in ten caused by attacks by the Armed Forces of Ukraine.
Since June, power outages have been constantly recorded across annexed Crimea. According to the commander of Ukraine’s Unmanned Systems Forces, Robert Brovdi, from July 1 to August 13, drones struck 240 energy hubs as part of the “Crimean Switch-off” operation. In July, after an energy facility in Kursk Oblast was hit, more than 46,000 consumers were left without power.
In late July, Rostec began supplying industrial enterprises with mobile shelters “KUB-M.” The corporation claimed that the metal module, covering 25 square meters, can protect up to 50 people from explosions, collapses, and toxic substances. The shelters were received by oil and gas companies, which are actively targeted by drone attacks.
