Gurugram, May 14 -- Residents across several parts of Gurugram, including Sectors 37D and 66 and localities such as Om Nagar, Gandhi Nagar, Shivaji Nagar and Badshahpur, continue to face recurring power disruptions. The latest major outage in Sector 37D affected at least 5,000 families and lasted around 30 to 33 hours from Monday afternoon to late Tuesday night, according to residents and officials. Nearly five group housing societies, including Ramprastha City and four Signature Global societies-several without full power backup-were affected due to faults in a shared 33kV underground feeder line connected to the 220/33kV substation in Sector 85. Dakshin Haryana Bijli Vitran Nigam Limited (DHBVNL) officials said the 33kV feeder, laid by the realtor, developed a fault on Monday evening due to overloading. Residents said the outage began around 2pm to 3pm Monday, with normal supply restored around 11pm Tuesday, though intermittent disruptions continued due to internal issues. Prakash Jha, a chartered accountant and resident of Signature Global Millenia-III in Sector 37D, said: "Diesel generator backups remain confined to common areas, leaving hundreds of families to struggle with basic amenities. A similar 30-hour outage occurred on April 23." He added: "We faced another major power outage issue hardly 20 days back." We need urgent intervention." Another resident of Sector 37D, Ranjeet Kumar, said, "Affordable housing societies were the worst affected, alleging the existing cable network frequently trips due to operational load falling short of actual demand." Vijay Kinger of Ramprastha Society alleged, "Neither the realtor nor the discom takes onus to fix the issues. We pay maintenance, energy bills and all other utilities on time. yet end up suffering for hours." Dinesh Raina, an RWA president in Ramprastha said: "Representatives of the realtor handling the power supply allege that the outage is due to a fault from the side of the discom. When we contacted them, they alleged that fault in the 33kV private feeder laid by the realtor for powering the society was the cause of the outage." In response to the plaints, Manoj Kumar Nehra, executive engineer (city division), said, "It was the 33kV underground feeder. which developed a fault by 4pm on Monday," adding maintenance is not the discom's responsibility. Supply was restored by 12.58am Tuesday. Manish Wadhwa, sub divisional officer (DHBVN), said: "A coordinated action is required for smooth functioning." In Sector 66 and Badshahpur, residents said repeated outages affect commercial establishments, with Aditya Singh noting "genset costs at least three times as much burdening businesses." DHBVN officials said transformer upgrades are underway, and single-core cables have been replaced with insulated wires in Om, Hira, and Shivaji Nagar. A senior official said field teams work three shifts around the clock to restore supplies....
