Western suburbs plunged in darkness for 6-odd hours
The western suburbs of Malad, Kandivli and Borivli faced unexpected power cuts yesterday after two lines of 220 KV each tripped, resulting in load shedding starting 5.30 pm.
The blackout continued till the time of going to press and officials said the fault was expected to be rectified by midnight.
Sources within the power sector said that the first line tripped at 5.30 pm and the second at 6.30 pm, interrupting power supply at many locations. The two lines are under the care of Tata Power, which also supplies power to Reliance Infrastructure. As such, the latter’s consumers were also affected.
A shortfall of 80 MW was recorded after the tripping of the first line, which resulted in additional strain on the second. Officials from Tata Power said that there were technical faults in both the supply lines.
Sources said the power cables are very old and the smallest strain can lead to their tripping. They added that initially there were problems in pinpointing the exact location of the fault.
By evening, locals claimed, there were power cuts across many areas in the suburbs. Tata Power and Reliance Infrastructure carried out rotational load-shedding of 30 minutes each in different areas to manage the load.
