Power outages struck apartment complexes in Seoul and Suwon around 2 a.m. this Thursday [1].
The failures occurred during a period of intense tropical nights, leaving hundreds of residents without air conditioning or cooling systems during high temperatures.
In Seoul's Dobong-dong neighborhood, a transformer failure plunged seven apartment blocks into darkness [1]. The outage affected approximately 500 households [1]. The complex utilizes three on-site transformers, but one of these units failed [1].
Song Jun-yong, a resident of the Dobong-dong complex, described the moment the power failed. "Suddenly, there was a loud noise from outside, like a bomb exploding," Song said [1].
Crews from the Korean Electric Power Corporation (KEPCO) arrived at the scene to investigate the cause. Technicians are examining both the on-site equipment and external utility poles to determine why the transformer failed [1].
A separate but similar power outage occurred in the Yeongtong-gu district of Suwon, Gyeonggi Province [1]. That incident affected about 900 households [1].
Residents in both locations reported spending the night awake, using handheld fans to cope with the heat while waiting for power to be restored [1].
“"Suddenly, there was a loud noise from outside, like a bomb exploding,"”
These simultaneous failures in Seoul and Suwon suggest that aging electrical infrastructure may be struggling to meet the peak demand caused by extreme summer heat. When a single transformer fails in a high-density residential complex, the lack of redundancy can leave hundreds of people vulnerable to heat-related health risks.
