Substation fire in Kryvyi Rih after a drone strike

What happened

A drone attack caused a fire at a Ukrenergo substation in the Dnipropetrovsk region and damaged equipment there and on two high-voltage overhead lines serving Kryvyi Rih. The report said this was the third strike that night with Shahed drones on energy infrastructure in the Dnipro region, and that shelling and falling drone debris caused the damage. As of 07:30, about 7,500 residential and industrial customers in Kryvyi Rih were without electricity. Ukrenergo began emergency repairs after the air alarm ended, and the report said customers were being supplied with power.

Contributing factors

The source attributes the fire and the damage to a drone attack, including shelling and falling drone debris. No equipment fault is described.

Lessons learned

1. A strike can damage substation equipment and nearby overhead lines in the same event, so restoration planning should cover both.
2. Repair work may have to wait until an air alarm ends, which delays the start of recovery.
3. Outage figures should be tied to a stated time, because supply can begin to return while repairs are still under way.
