Local train
The state chief secretary met various department heads and police officers to discuss the demand for increasing local train services and has taken a decision to allow women to use local train services during non-peak hours.

Mumbai’s local train services were partially restored on Monday (October 12) after a power grid failure in the city. The power supply was hit due to Tata Power’s incoming supply failure, the Brihanmumbai Electric Supply and Transport (BEST) said.

The Central Railways said its Harbour Line was restored around 11 am and that its engineers were in touch with the power grid experts. In a tweet, it appealed to commuters not to panic and asked them to avoid walking on the tracks.

Mumbai’s local trains are the city’s lifeline, as they ferry an estimated 80 lakh people every day. Three distinct systems — the Central Line, Western Line, and the Harbour Line — together form the city’s overall train commuter service.

Juhu, Andheri, Mira Road, Navi Mumbai, Thane and Panvel were among the areas that were largely affected. A Brihanmumbai Electric Supply and Transport (BEST) spokesperson confirmed: “Due to grid failure, the supply of power in the city is disrupted.”

Hours later, Adani Electricity tweeted: “There is a major power grid failure due to which supply is affected in most areas of Mumbai. As per grid safety protocols, Adani Power System has been able to sustain and islanded. Our teams are working to restore the supply in the affected areas at the earliest. We regret the inconvenience caused.”

Briefing citizens on the trouble, Energy Minister Nitin Raut said a technical failure in one of the circuits (Circuit 2) of a 400 KV line of the Maharashtra State Electricity Transmission Company Limited (Mahatransco) at the Kalwa-Padha GIS Centre had resulted in the power cut. “Repair and maintenance work on the other circuit (circuit 1) at the centre is underway,” he said.

In hospitals, while no disruptions were reported so far, authorities immediately began a battery-back up for ventilator and ICUs. They were directed to ensure back-up for four hours. “We have 1,000 litres of diesel in surplus and generator that will last for 12 hours. We started the generator the minute the electricity supply was cut. We are arranging for additional supply if needed. No patient was inconvenienced,” Dr Rajesh Dere, Dean of BKC jumbo covid facility, said.

Authorities also cautioned citizens against a reduced water supply. “There will be reduced water supply or no supply. So a request to use water judiciously,” a statement by a BMC corporator read.

Sources said BEST takes supply from Tata Power whose major transformer in Kalwa and Pardha has suffered multiple tripping and failed. Tata also supplies power to Adani which then distributes outside city limits, while BEST provides power in the island city. The Kalwa transformer is the main supply line that provides 350MW to Mumbai.

The state’s Common Entrance Test (CET) exam, which began today, were conducted using power generators. The first shift of the exam was from 9.30 am-12.30 pm. “Due to the power backups, we have been able to continue the exam,” an official from the state CET cell said. The next shift will begin at 2.30 pm.

The effect of the power outage was also felt at the Bombay High Court where videoconferencing proceedings were halted till resumption of services, the registrar said.

However, airport operations remained unaffected.
