Fire at an overloaded substation in Odesa leaves nearly 500,000 without power

What happened

On a Saturday reported in early February 2023, a fire broke out at an overloaded substation in the port city of Odesa, Ukraine. Reporting said nearly 500,000 people were left without electricity. Power was later restored to critical infrastructure. It is not reported whether supply was restored to all affected customers, or what damage the fire caused.

Contributing factors

The source describes the substation as overloaded. Wider strain on Ukraine's grid was reported at the time, but it is not established as the cause of this fire.

Lessons learned

1. An overloaded substation can fail by fire and interrupt supply to a very large number of customers.
2. Restoration plans should prioritise critical infrastructure and state clearly what has and has not been restored.
3. Early public reports should keep the cause, the extent of damage and the number still without power separate until they are confirmed.
