Taking a suo motu cognisance of Thursday’s three-hour long power failure in city suburbs, the Maharashtra Electricity Regulatory Commission (MERC) has asked the two suppliers Tata Power Company and RInfra to submit its findings on November 25.

A MERC spokesperson said the commission would hear all parties involved, including the State Load Dispatch Centre that monitors power transmission and keeps authentic records, to present their cases.

“The companies will also be asked to submit their plans that would help avoid similar blackouts in future,” said the spokesperson.

MERC took a notice of the development because two companies were engaged in a blame-game while justifying the outage that hit 28 lakh suburban consumers, including airport and hospitals on Thursday. Power was restored in phases by late evening. The trouble started at 5.45 pm.

Tata Power Company supplies to the airport and it also supplies to other 80,000 commercial consumers such multiplexes, malls, offices and residential suburban consumers using RInfra’s distribution network.

The suppliers, Tata Power Company and RInfra, started blaming each other for the blackout.

Tata said the failure of power supply has been primarily due to tripping (shut down) of the Dahanu plant along with the 3 receiving station of RInfra.

RInfra countered the claim by producing SLDC records that said that Tata’s Trombay-Salsate transmission line tripped first which then overloaded RInfra system.

Tata said Trombay-Salsate lines also tripped but added that the cause for this failure was yet to be ascertained.

Since RInfra’s receiving substation too stopped working on Thursday, Dahanu’s 500 MW plant got tripped automatically.

RInfra said that their Dahanu power plant stopped working because of tripping of Tata’s Trombay-Salsate transmission line.
