On 17 August 2026, Russia's state defence-industrial conglomerate Rostec announced that serial production of mobile power substations had begun — units explicitly designed to restore electricity supply after drone attacks knock out grid infrastructure.
The producing entity is AKRON PT, a joint venture between Rostec's subsidiary RT-Design Technologies and AKRON Holding. Rostec announced the launch on its Telegram channel under the name 'Energy Ambulance in Case of a Blackout.' The conglomerate stated the systems are 'especially needed amid the risk of large-scale outages caused by drone attacks.'
The substations are mounted on wheeled truck trailer platforms, including off-road vehicles, and arrive fully factory-equipped, ready to connect to a power supply system immediately on delivery. They support different voltage classes, can be fitted with transformers of various capacities, and are adapted to operate in all climatic conditions, from Russia's southern regions to the Far North.
Vasily Zuikov, general director of RT-Design Technologies, framed the product's rationale in stark terms. Damage to power supply centres, he said, can cause outages lasting hours or days, while restoring large transformers can take weeks or months. A mobile substation bridges that gap, supplying power while permanent repairs are carried out.
AKRON PT specialists estimate that two to four mobile substations per region would be sufficient to cover any emergency power need. That figure has not been independently verified, and no production volumes, pricing, or delivery timelines have been disclosed. It is also not known which regions have placed orders or whether any units have already been deployed in an emergency.
The announcement follows an earlier move by the same Rostec subsidiary. On 4 August 2026, RT-Design Technologies and AKRON Holding were already offering Russian regions turnkey energy facility construction with integrated anti-drone protection, including unmanned aerial vehicle (UAV) detection and suppression systems. The serial production launch two weeks later marks a further step: moving from bespoke construction contracts to standardised, deployable hardware that can be stockpiled and dispatched at short notice.
The broader logic is one of redundancy over repair. Fixed grid infrastructure, once damaged, requires specialist equipment and time. A truck-mounted substation, by contrast, can be driven to a stricken district and plugged in within hours. Production volumes and the pace of any rollout across Russia's regions have not been disclosed, and Rostec has not said how quickly it intends to scale output.
What the launch does confirm is that Rostec has formally entered the civilian grid-resilience market — and that the rationale it has chosen to advertise publicly is protection against drone strikes rather than general infrastructure modernisation.
