What did Russian strikes do to Ukraine's power grid?

What was the state of Ukraine's energy system on 24 October 2022? By then, the reports from the preceding days described a country under sustained pressure on its power supply.

On 20 October 2022, a Russian missile struck a major thermal power station in Burshtyn, in Ivano-Frankivsk Oblast. Governor Svitlana Onyshchuk said it caused "quite serious damage". The strike showed that energy facilities far from the front line were being hit.

Two days later, on 22 October 2022, power outages were reported across Ukraine. Citizens were advised to store water, as Russian airstrikes across the country continued to damage critical infrastructure and energy facilities. The advice suggests that authorities expected disruption to more than electricity.

The weapons used were also in the news. On 20 October 2022, the United States reported that Iranian troops were in Crimea, assisting the Russian military in using Iranian drones. That report tied the strikes on infrastructure to an outside supplier of both equipment and, according to the US, personnel.

Taken together, the reports from 20 to 22 October 2022 show a pattern: repeated attacks on energy sites, outages spreading across the country, and international attention on the drones involved. Households were being asked to prepare for interruptions, and damaged plants such as Burshtyn were a concrete example of what was at stake.
