Extremely Frequent Power Cuts in Nerul Sector 15

Facing very frequent power cuts in Nerul Sector 15. For the last 5 days, everyday power has been cut for 1-3 hours.

What's happening? Any idea ?

I recently moved to Navi Mumbai from Kolkata and I can't believe this is so frequent. We used to get this level of power cuts back in 1990s.

What is happening ? Is it common here ?
