Large parts of Mumbai, Thane and Navi Mumbai faced a power outage on Monday, due to which several suburban and long-distance trains were held up. According to Brihanmumbai Electric Supply and Transport (BEST), the unprecedented electricity cut that was reported after 10 am was because of the failure of a power grid. Apart from local trains, traffic signals at some areas were also affected.

The power supply has been restored in most parts of the city. Meanwhile, the Mumbai airport and the stock exchange were functional amid the outage.
