What happened

A fire was reported at a substation in Smaznevo, in the Zalesovsky district of Altai Krai, Russia. The head of the district was quoted as saying the substation was on fire, that an emergency power outage affected the whole district, and that the fire was being put out, after which the substation was to switch to backup supply. Telegram channels reported an explosion, and early reports said a transformer caught fire. Neither point is confirmed in the district statement. No information about casualties was given.

Contributing factors

Not reported. An explosion and a transformer fire have been mentioned only in early media and Telegram reports.

Lessons learned

  1. Treat early claims of explosion or a specific failed component as unconfirmed until the operator or fire service states them.
  2. Plan how a district-wide outage will be covered if a substation must move to backup supply after a fire.
  3. Keep public updates limited to what is known about casualties, the fire, and restoration.
