Mumbai power outage cause discovered: Unprofessional management

As MSETCL 400 kV Kalwa-Padgha GIS circuit 1 for Mumbai was taken for repair; the load went to the second unit circuit, which suffered a snag

From the statement of the power minister of Maharashtra, it is now clear that the business capital of India had earlier today suffered a major outage as the management did not have a contingency plan amid maintenance of one supply unit. Following the massive power outage in Mumbai, Thane and Navi Mumbai, the power supply has resumed in Mumbai Central, Byculla, Tardeo, Andheri, Bhandup, Vikhroli, Churchgate, Sion, Chembur and Belapur. Train services were also restored on both Central and Western Railway lines.

Power outage in Mumbai on 12 October brought the local trains, the city’s lifeline, to a standstill for nearly 2.5 h, causing hardships to commuters. In the congested local train coaches, as people nearly suffocated with fans and lights not running, many passengers disembarked and walked on tracks to reach the nearest station or road.

According to railway officials, this was a rare occurrence in the recent past when the suburban services on both the Central Railway (CR) and Western Railway (WR) routes came to a halt due to power grid failure.

Chief minister Uddhav Thackeray spoke to state power minister Dr Nitin Raut and BMC commissioner IS Chahal over grid failure in Mumbai and gave directions for its restoration as soon as possible, according to Maharashtra CM’s office.

“Chief minister has given instructions for the restoration of power supply as soon as possible. He has also instructed departments like fire brigade, etc. to remain vigilant during this time of need. The Chief Minister has also instructed the local authorities to make proper arrangements for the standard passengers of Mumbai local trains,” as per an official statement.

Mumbai power outage: Minister explains cause

Maharashtra Energy Minister Nitin Raut said that MSETCL 400 kV Kalwa-Padgha GIS circuit 1 was not available today due to repair and maintenance job. The load, therefore, moved to the second unit circuit. There was but a technical problem in the second unit, which led to a major power outage across Mumbai Metropolitan Region, said Raut.

Officials said it would take 30 min to an hour for complete restoration of power. Electric supply has resumed at a few places.

Multiple lines and transformer (Kalwa-Padghe and Khargar ICTs) supplying power to Mumbai system tripped today due to the cascading effect of the load, sources said. The supply in Mumbai and suburbs was the worst affected.

“The electric supply in island city is interrupted due to Tata Power’s incoming electric supply failure,” said a BEST official.
