Windstorm’s Impact Mumbai’s Power Grid Faces Temporary Disruptions

Mumbai, a bustling metropolis on India’s western coast, faced about of technical disruptions in its power supply infrastructure on Monday, as strong winds wreaked havoc on the city’s electricity grid.

The Maharashtra State Electricity Transmission Corporation Limited (MSETCL) substation in Kalwa bore the brunt of the wind-induced chaos, experiencing a sudden technical snag that led to power outages for consumers serviced by the Brihanmumbai Electric Supply and Transport (BEST) Undertaking. The incident unfolded in the afternoon when gusty winds, accompanied by dust, swept through Mumbai. At approximately 4 pm, sparks were observed at the MSETCL substation in Kalwa, coinciding with the onset of the technical glitch. Transformers at Kalwa and Kharghar also tripped around this time, exacerbating the disruption in power supply across the city.

While officials from MSETCL assured that the issue was promptly addressed within 10 minutes, residents reported lingering effects of the power cuts well into the evening. At least nine feeders supplying electricity to end consumers were affected by the storm, impacting areas such as Prabhadevi, Dadar, Matunga, and Chhatrapati Shivaji Maharaj Terminus, all serviced by the BEST Undertaking. However, authorities claim that power was restored to affected areas within 15-20 minutes of the onset of the disruptions.

The sudden disturbance in power supply also coincided with a notable decrease in electricity demand across Mumbai. Data from the Maharashtra State Load Despatch Centre revealed a drop in demand from 3,700 megawatts to 2,800 megawatts within 30-45 minutes of the storm. This decrease in demand was particularly noticeable among BEST consumers, with electricity demand plummeting from 850 megawatts to 575 megawatts during the peak of the disruptions. While the storm-induced power snags primarily affected consumers serviced by the BEST Undertaking, major power suppliers such as Adani Electricity and Tata Power reported minimal disruptions to their services, serving as a testament to the resilience of their infrastructure amidst adverse weather conditions.
