It is current news, Power is being restored as I post this.
A bit soon to have an answer, but some chatter about a "Grid Failure"
""The electric supply is interrupted due to TATAs incoming electric supply failure. Inconvenience is regretted," Brihanmumbai Electric Supply and Transport (BEST) had tweeted.
"Due to a technical glitch in Circuit 2 of the Kalva-Padghe powerhouse, the regions between Thane and Mumbai are facing a power cut. Our staff is working on it and power will be restored in an hour or 45 minutes," Maharashtra Energy Minister Nitin Raut said."
Possibly a side effect of planned maintenance?
This has a listing of events. Scroll toward the bottom.
Looks like it started with one circuit tripping, and then the event cascaded. Likely more to the story.

Kind of shows the system had very little spare, but also a couple of the lines at least were out for maintenence. Some systems seem to have survived as island supplies.
Once people start getting off trains and walking though that makes it impossible to re-start services.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

The preliminary investigation findings of Tata Power on the incident are attached.
Tripping of 400kV lines on overload suggests of Zone-3 element of distance protection.
(I don't think these lines are provided with overload protection, just current based).
