For Gurgaon residents Ishan Mohan and Ankur Bora, Friday evening didn’t go as planned. One was left sweating through a six-hour blackout in Sector 31, repeatedly calling electricity officials for help. The other watched his workday collapse as backup power failed, roads went dark, and even the Rapid Metro abruptly shut down.As temperatures soared and metro commuters were forced to walk along tracks in the dark, residents flagged that Friday’s power outage was a stark reminder of how Gurgaon’s rapidly growing power demand is outpacing its fragile infrastructure.“I work from home, so calls were affected because backup can only run for so long. We ventured outside then but it was all dark there too, and we could not take the Rapid Metro anywhere as that also got shut,” said Ankur Bora, a financial services professional living in the Suncity township on Golf Course Road.In Sector 31, public relations professional Ishan Mohan said his locality remained without electricity long after power was reportedly restored elsewhere.“Although electricity returned in most areas, our locality remained without power for over six hours and we had to personally reach out to DHBVN officials before action was taken,” he said.While Mohan acknowledged that the response later became prompt, he said such disruptions have become increasingly common during Gurgaon’s summers.“Such prolonged outages are not unusual in Gurugram, especially during summers and the monsoon, largely due to weak power infrastructure. Incidents involving transformers and electrical systems catching fire or malfunctioning have also become a recurring concern,” he added.Story continues below this adAccording to Dakshin Haryana Bijli Vitran Nigam (DHBVN) spokesperson Sanjay Chugh, the blackout was triggered by a technical fault at the Sector 72 power station, where the current transformers (CTs) of both 220 KV circuits were damaged. The fault disrupted supply to substations serving Sectors 15, 38, 44, 46, 52, 56, and the Maruti area.“One circuit was restarted within half an hour. The Rapid Metro service was impacted for about 35 minutes, from 7:50 pm to 8:25 pm, after which its supply was restored,” Chugh said.He explained that because the entire electrical load initially had to be shifted to a single operational circuit, precautionary power cuts were imposed in several areas.“However, through the continuous, coordinated efforts of DHBVN and HVPN teams, the power supply from both 220 KV circuits at PGCIL Sector 72 was fully normalized by 10:10 pm,” the spokesperson added.Story continues below this adDespite the official restoration timeline, residents across the city reported prolonged outages lasting well into the night.Pawan Yadav, president of the Residents Welfare Association of Sushant Lok Extension, said electricity in his area only resumed at 5 am.“Our residents were very troubled and we had to keep nagging DHBVN officials. Moreover, a CR/PT (transformer junction box) in our area tripped at 9 pm and took three hours to fix, aggravating the issue. The deeper issue is the power supply just cannot handle our society’s internal load fully and this leads to frequent cuts in summers,” he said.The outage also triggered chaos on the Rapid Metro network, with commuters venting frustration on social media as trains stalled in extreme heat.Story continues below this ad“I didn’t know that power cuts in Gurgaon also affected the metro. At Phase-3 Rapid since last one hour in immense heat, no power, no arrangements. Absolutely mental!” an X user named Vatsal posted at 8.18 pm.“I am also stuck in the metro for the past half hour. AC is off and gates are also closed in this heat. No one has reached out or asked about the situation and the driver is not helping,” another user, Rohit Sharma, posted at 8.20 pm.The disruption comes at a time when Gurgaon’s power consumption is surging dramatically, placing increasing strain on its electrical network. According to DHBVN data for May 21, 2026, the Gurugram-I and Gurugram-II circles together consumed 518.9 lakh units (LUs) of electricity in a single day.Gurugram-II – covering newer residential and commercial sectors including DLF areas – recorded 323.59 LUs of consumption, marking a massive 55.68% rise compared to the same day last year. Much of this demand came from urban households.Story continues below this adGurugram-I, which covers older parts of the city and surrounding areas like Pataudi, consumed 195.31 LUs, driven by both domestic and industrial usage.
