Resilience against intensified air campaigns

Ukraine has successfully navigated the most challenging winter of the conflict, characterized by a record breaking Russian air campaign and extreme weather conditions. Between January and March 2026, Ukrainian authorities documented the launch of over 1,700 attack drones and 700 missiles. President Volodymyr Zelenskiy noted that during the final week of winter alone, Moscow deployed more than 1,720 drones and 1,300 guided aerial bombs. The scale of this assault was designed to push the national energy infrastructure to a total breaking point, yet the grid managed to avoid a catastrophic failure.

Impact of extreme sub-zero temperatures

The military assault coincided with a period of severe environmental strain, as daytime temperatures plummeted to minus 20 degrees Celsius. This combination of kinetic strikes and deep frost brought several regions close to a humanitarian crisis. In major urban centers like Kyiv, particularly on the eastern bank of the Dnipro River, residents faced emergency blackouts lasting over eight hours. Hundreds of high-rise apartment blocks were left without centralized heating as the infrastructure struggled to cope with the dual pressure of physical damage and record high heating demand.

Strategic strikes on nuclear infrastructure

The most critical moment for the energy sector occurred on February 7, when Russian forces targeted substations directly linked to Ukraine's nuclear power plants. According to Vitaliy Zaichenko, head of the state grid operator Ukrenergo, this specific attack reduced the electricity output from the nuclear fleet by approximately 50%. These strikes were part of a broader campaign against the state’s energy assets; Naftogaz reported 229 attacks on its facilities over the past year, a figure higher than the previous three years combined.
