A newspaper reported that "The blackout occurred at around 3:37 p.m. in a southern residential district of Ulsan, about 300 kilometers southeast of Seoul, due to a malfunctioning substation, according to the industry ministry and the state-run utility Korea Electric Power Corp. (KEPCO). The power outage was caused by a malfunctioning switch isolator at the substation," a KEPCO official said, noting it was trying to determine the cause of the accident. KEPCO said it has fully resumed operation of the substation after restoring power to the affected households at around 5:25 p.m.
