TATA Power, the power supplier for Mumbai, has informed that At 10.10 am, there was simultaneous substation tripping in MSETCL’s Kalwa, Kharghar causing a huge dip in frequency in Mumbai transmission system which led to tripping of power supply. They informed that they are working to restore power supply by bringing supply from the 3 Hydro units & Trombay units.

As per sources quoted by Indian Express, the BEST procures electricity from Tata Power whose major transformer in Kawla and Pardha had suffered multiple tripping and failures. This is the major transformer that is the main supply line that provides 350 MW electricity to Mumbai. Tata also provides electricity to Adani power which then distributes outside city limits, while BEST provides power inside the city.
