The Brihanmumbai Municipal Corporation (BMC) has considered electrical supply disruption as one of its biggest challenges during disaster management. The power outages of 8 hours in October 2020 in the city and disruption of electricity supply for weeks in Chiplun, Koyna or after the Kerala floods put a big question mark over the disaster preparation plan of the city, as all the operations have 100 per cent dependency on electricity. The director of the disaster management department of the BMC has also emphasised the issue of tracking people in the absence of mobile networks.

Power outages during extreme weather events like cyclones or heavy rains are common in rural areas. In the past few years the city has been facing issues of extreme events and though the city gets 24 by 7 power supply the issue of supply disruption poses a big challenge. Mahesh Narvekar, director of the Disaster Management Department said  besides floods there are many other issues related to rain like cyclone, landslides, lightning, tree falls, electrocution, short circuit, buildings collapse, epidemics, even chemical hazard. The disaster management department deals with all of them.
