Mumbai witnessed a massive power outage around 9.40am on Sunday morning, affecting electricity supply in almost all parts of the city. Maharashtra government officials told CNBC TV-18 that due to the tripping of the MSEB 220kv transmission line on Mulund-Trombay, power supply to most parts of Mumbai has been affected.
The power outage affected the entire city and almost every aspect of the city’s day-to-day functioning.
Railway officials told CNBC TV-18 that due to the power outage, almost all local trains in Mumbai and the Mumbai metropolitan area came to a halt. The Central Railway claimed train service on the Central Route was restored after 10 minutes. On the western line, the route between Churchgate-Mumbai Central is still affected, but service between Mumbai Central-Vile Parle has been restored, officials said.
Due to this disruption of commuter train services, many passengers got stranded on the trains, and some of them got off and started walking on the tracks.
Authorities said they were constantly checking with different agencies, residential companies and commercial facilities to make sure people weren’t stuck in elevators.
At the time this copy was published, power was back in some areas of the city such as Nariman Point and Wadala. Authorities said power throughout the city will be restored by noon.
Prior to that, it was in October 2020 that Mumbai experienced a similar blackout. Meanwhile, the possibility that a cyberattack was the reason for the outage began to creep in.
The Maharashtra government had earlier formed an eight-member committee to investigate the power outage, led by Prof. Fernandes, IIT-Mumbai, Department of Electrical Engineering.
The panel submitted its report in November 2020 and cited cascade triggering as the reason and ruled out the cyber sabotage angle. The committee report mentions that due to heavy rains that year, the Talegaon-Kalwa line was damaged. This weighed on the other three lines and resulted in the October 2020 blackout.
But in March 2021, a US-based company released a report mentioning that some unidentified Chinese entities were involved in the power outage. After the report was released, Maharashtra government ministers also started talking about a foreign hand responsible for the blackout.
Further investigations have been ordered by the Center and state governments and many of these reports have yet to be submitted.
