Train services came to a halt, homes and businesses were without electricity and people sweltered in humid heat as a grid failure resulted in massive power outages across Mumbai on Monday.
As the day progressed, power restorations efforts began on “war footing”.
Railway services across city on the Western Railway and Central Railway came to a grinding halt at 1005 hrs as a result of the power outage, with both the networks blaming power cut from Tata Power (their power supplier) for it.
State’s Power Minister Nitin Raut said the trouble emanated from Maharashtra State Electricity Transmission Company (MSETCL) facilities during a planned maintenance work.
Tata Power, which is into both generation and distribution, attributed the power outage to a simultaneous substation tripping at 1010 hrs at state-run transmission company MSETCL’s two substations in the suburbs of Kalwa and Kharghar.
Raut said power supply will resume soon, as officials were working on it on a war footing.
As the afternoon progressed, power at many pockets including the Bandra Kurla Complex business district, Lower Parel and South Mumbai started resuming.
With work-from-home (WFH) becoming the norm across vital industries like banking, finance and information technology, employee output was also impacted as the residences do not have electricity backup in a city which generally has stable power.
