Parts of Mumbai's suburbs faced disruption in power supply for several hours on 29-06-2016 after a transmission tower at Airoli on the Kalwa-Satte transmission line collapsed.
Several areas such as Kurla, Andheri, Goregaon, Malad, Kandivli and Borivli suffered power outages as the Kalwa-Satte lines 3 and 4, maintained by Tata Power, had to be taken out of service to attend to the collapsed tower.
Reliance Energy, which predominantly supplies electricity to the suburbs, restored power supply around 1.30 pm Wednesday, but has warned of possible rotational load-shedding till the technical glitches are fixed.
A company spokesperson said, "In case the repairing of the tower by Tata Power takes a longer time, Reliance Energy may have to resort to rotational load shedding for another day or two to maintain stability of Mumbai's power distribution system."
According to information from Tata Power, Reliance Infrastructure sources its power requirement of about 750 megawatt from outside Mumbai and uses the Kalwa-Satte transmission lines for importing electricity. The company will, thus, need to resort to rotational load shedding due to unavailability of power supply.
The transmission tower at Airoli collapsed Tuesday evening, plunging several areas in the dark for about 45 minutes. It once again suffered power disruptions Wednesday morning.
"The tower is likely to have fallen due to methane gas corrosion from the garbage dump at the foot of the tower or the removal of a few structural members by elements that visit the garbage dumps. Tata Power is working on providing an alternate route, which may take around five days," said a Tata Power official.
