A major power outage disrupted large parts of Gurugram on Friday evening after a transformer explosion in Sector 72 triggered the collapse of the local electricity grid, affecting homes, businesses and metro services across the city. The incident also halted operations on the Rapid Metro Gurugram for nearly 45 minutes, leaving several passengers stranded inside trains.
According to officials, the disruption began around 7:50 pm after a technical fault caused oil leakage in a 220 KVA current transformer. The leakage reportedly led to a blast when the breaker was being disconnected, triggering a fire and causing a widespread blackout. Authorities said the incident interrupted power supply from the 220 KV substation to multiple areas, including Sector 52 and Sector 56, along with five associated substations.
Officials stated that thermal heating was believed to be the primary cause behind the transformer malfunction. Emergency teams and engineers were rushed to the site to contain the fire and restore electricity supply. The blackout occurred during extremely hot weather conditions, with temperatures in Gurugram touching nearly 41 degrees Celsius, intensifying discomfort for residents and disrupting commercial operations across the city.

The Delhi Metro Rail Corporation confirmed that metro operations were significantly affected due to the power failure. A DMRC spokesperson said train services on the Rapid Metro corridor and the Gurugram section of the Yellow Line remained suspended between 7:50 pm and 8:33 pm because of the outage linked to the Sector 72 substation operated by Haryana Vidyut Prasaran Nigam Limited.
Videos shared on social media showed passengers walking along metro tracks after trains came to a standstill during the disruption. Metro authorities later confirmed that commuters were safely evacuated under staff supervision and no injuries were reported. The incident nevertheless caused inconvenience and delays for hundreds of office-goers and daily commuters during evening peak hours.
Power supply and metro services were eventually restored after technical teams stabilised the system and repaired the affected infrastructure. Authorities said a detailed investigation would be conducted into the transformer blast and associated grid failure to determine the precise cause of the incident and prevent similar disruptions in the future.
