Ukraine's energy system has become more fragile than a year ago. This is reported by The New York Times.
This winter, power plants will supply 4.5 gigawatts of electricity, a third of the pre-war volume.
In the summer, the UN gave the same assessment of generation, indicating little progress in repair work.
Although Ukraine has improved its ability to shoot down drones and its most important facilities are protected, experts believe that in the event of successful attacks by the Russian armed forces, the country will have few sources of backup power.
