Gurgaon: More outages feared as Sector-72 sub-station develops major fault

Utility officials said they are sourcing from sub-stations in nearby areas to meet the demand

City residents will continue to bear the brunt of power cuts over the next couple of weeks or more. The sub-station of the Dakshin Haryana Bijli Vitaran Nigam (DHBVN) at Sector 72 tripped on Tuesday afternoon, causing a shortfall of 550-MVA and affecting half of the city in terms of power cuts.

The areas located along Sohna Road, Golf Course Road and Golf Course Extension Road were the worst-hit. Such is the shortfall that the DHBVN engineers are in the process of sourcing additional power from neighbouring areas to meet the daily need.

“We are in the process of arranging electricity from the sub-stations in neighbouring areas such as Jhajjar and Palwal. The fault developed suddenly and it will take another 10 days or more to repair it,” said Sanjiv Chopra, chief engineer (CE), Smart Grid Project, DHBVN, Gurgaon.

The official said that around 3pm on Tuesday, two transformers of the Sector 72 substation of the state utility tripped. The trip was triggered by a substation of the Power Grid Corporation of India Limited (PGCIL).

“Power tripped due to damage to the cables of one of the transformers at the power grid sub-station. The damage to cables and the power trip at our sub-station caused a sudden loss of 550-MVA,” said Chopra.

The DHBVN later restored one of the transformers around 5.30pm but the capacity was reduced to 270 MVA.

“It would take another 10 days for the power grid to be restored,” Chopra said, adding that the fault led to a sudden electricity deficit in Gurgaon.

Chopra said the Haryana Vidyut Prasaran Nigam (HVPN) has managed to source electricity from substations at Rangala Rajput and Pali to meet the demand for now.

“We are trying our best to cope up with the situation. However, there will be scheduled power cuts across New Gurgaon,” Chopra said.

Meanwhile, the DHBVN and HVPN officials are in touch with PGCIL officers to replace the damaged transformer and cable to restore normal service as early as possible.

Neeraj Yadav, resident South City 2, said, “We have been badly affected by power cuts and the elderly and children suffer the most. Tripping happens frequently and we are starting to lose our patience.”
