A major technical snag hit the power supply in Chandigarh, resulting in a complete blackout in most areas of the city beautiful for long hours on Wednesday night.
Sectors 10, 11, 15, 25, 32 to 40 and 43 to 56 of Chandigarh faced seven-hour long power cut around 6.30 pm onwards.
The affected sectors get their power supply from the 66-KV grid station in Mohali, about 10 km from Chandigarh.
"The disruption was caused by a technical problem at the Mohali grid station which is now being repaired," said M.P. Singh, superintendent engineer of the Chandigarh electricity department.
Residents of Chandigarh, the capital of Punjab and Haryana, complained that officials failed to give them any information on the outage.
"The officials were not able to inform us as to when the (power) supply would be restored. We had to come outside our houses. Even street lights were not working," J.N. Sharma, president of the New Light housing society in Sector 51, told IANS.
The supply was restored in some sectors at around 12.30 am However, the problem of low voltage persisted in many areas till 9 am.
