SHOSTKA: As the lights went out in her hometown, 40-year-old Zinaida Kot could not help but think about her next dialysis treatment for kidney disease. Without electricity, the machine that keeps her alive stops working.

Kot is among millions of Ukrainians who are bracing for another winter of power cuts and possibly blackouts as Russia renewed its campaign of attacks on the country’s energy grid. Analysts and officials say that this year Moscow has shifted tactics, targeting specific regions and gas infrastructure.

In some regions — mostly those closer to the front line in the east — the season of buzzing generators has started, as well as long hours of darkness with no power or water. People are once again pulling out small power stations, charging numerous power banks, and storing bottles of water in their bathrooms.

The attacks have grown more effective as Russia launches hundreds of drones, some equipped with cameras that improve targeting, overwhelming air defenses — especially in regions where protection is weaker.

The consequences are already reshaping daily life — especially for those whose survival depends on electricity. For Zinaida Kot, who has been on dialysis for seven years, this is far worse than mere discomfort.
