The IEEE Spectrum article examines the extraordinary efforts of Ukrainian electrical engineers working to repair the country’s power grid amid ongoing attacks on critical infrastructure during the war with Russia. Since the full-scale invasion in 2022, Ukraine’s energy system has become a frequent target of missiles and drone strikes, forcing engineers and technicians to operate in dangerous conditions while attempting to restore electricity to millions of residents.
Repairing the grid has become both a technical and humanitarian challenge. Crews must often rush to damaged substations and transmission lines shortly after attacks, sometimes while new strikes remain possible. The work is hazardous: injuries among workers in electricity generation, transmission, and distribution have increased sharply since the invasion began, and dozens of engineers have died while performing repairs.
One of the engineers highlighted in the article is Oleksiy Brecht, a senior operations leader at the Ukrainian grid operator Ukrenergo. Brecht played a crucial role in strengthening the resilience of the national grid before and during the war. Among his contributions was reintroducing “live-line” maintenance techniques, which allow crews to repair transmission equipment while circuits remain energized, enabling electricity to continue flowing to homes and critical facilities.
Brecht also helped prepare Ukraine for one of the most significant strategic changes to its energy system: disconnecting from Russia’s power network and synchronizing with the European grid. This move provided additional stability and backup electricity during wartime disruptions.
The article recounts Brecht’s final day during a major Russian attack that involved missiles and hundreds of drones targeting Ukraine’s energy infrastructure. While helping lead repairs at a heavily damaged substation, he accidentally touched an electrified busbar and was killed. His death underscores the extreme risks faced by engineers responsible for keeping the country’s power system functioning.
Despite repeated destruction, Ukrainian engineers continue to restore power through ingenuity and rapid improvisation, redesigning damaged systems when replacement equipment is unavailable. Their work has become an essential part of the nation’s resilience, ensuring electricity continues to reach homes, hospitals, and critical services even under wartime conditions.
