State to probe power failures

Maharashtra Electricity Regulatory Commission

Worried about the two successive power breakdowns in the city last week, the state electricity regulator has started inquiring into the technical failures and looking for measures to avoid such instances.

Taking suo motu cognisance, the Maharashtra Electricity Regulatory Commission (MERC) asked Tata Power Company and Reliance Infrastructure (RInfra) to submit their reports on the three-hour outage on November 18.

On Monday, the regulator again asked the utilities, including island city supplier Brihanmumbai Electric Supply and Transport (BEST), to furnish details of Sunday’s power breakdown, reasons and a corrective plan to pre-vent such incidents in the future.

A hearing will be held on Thursday at the MERC headquarters.

The regulator initiated inquiry primarily because the companies involved made contradictory statements; and instead of giving out information were busy pointing fingers at each other.

“The MERC wants to know the exact reasons that caused major power failures twice in three days because the megapolis cannot continue to suffer like this,” said a MERC official requesting anonymity, because he is not authorised to talk with media.

On Sunday evening, many parts of the south and south-central Mumbai went without power following a tripping in receiving station in Dharavi.

Parts of the island city were plunged in darkness for an hour from 5.15pm. Even railway services were delayed because the signals were not working.

BEST officials said the power failure on Sunday took place because the Tata transmission line between Trombay and Dharavi tripped.

Tata Power’s receiving station in Dharavi, which supplies electricity to seven other substations in the island city, was affected.

As a result of this failure, power in some eastern suburbs too went off. RInfra supplies power to these areas.

The blackout on November 18 occurred due to a tripping of Tata Power’s Trombay-Salsette-Borivli 220 KV transmission lines. The Dahanu Thermal Power Station had tripped because of overloading of the system, resulting in power failure in the suburbs.
