Maharashtra Energy Minister Nitin Raut announced that a four-member inquiry committee has been set up with a mandate to examine the causes of the power failure and to find out if it was caused due to negligence. The probe will also find out why only 50% of the repair of the GIS system was done. The committee will also suggest measures to be adopted to avoid such incidents in the future.

The committee will submit its report within a week. Further, the MahaTransco has been directed to conduct root cause analysis and a technical audit of the transmission systems in the state. The repair and maintenance protocol will be strengthened.

Tata Power released a statement explaining the reasons for the power outage and expressed regret for the inconvenience caused to the customers. 

Here is the statement:

“Based on the preliminary assessment of the situation, Tata Power would like to inform that today many parts of Mumbai experienced an unforeseen electricity failure starting at 10 am in the morning due to tripping of MSETCL’s 400 KV transmission system at Kalwa which supplies to Mumbai and adjoining areas. MSETCLs 400kV Pune-Kalwa line was under forced shutdown since yesterday due to R-Y phase fault.

It is understood that MSETCL had taken emergency shutdown for 400 KV Kalwa- Padghe line -1 at 6.54hrs today morning to attend fault and was expected to be revived by 09:30hr, but could not revive it. 

As understood, at 09:58hrs 400kV Kalwa-Padghe-2 carrying 633 MW tripped. The flow on Pune-Kharghar rose upto 900MW and tripped at 10:00hrs resulting in load drop in Mumbai system.

Mumbai’s islanding system that saves the city from major power outages was separated, however it could not hold as additional 900MW load dropped at 10:05hrs. 

Tata Power swiftly began restoration work to bring back supply from the 3 Hydro units and Trombay gas and coal units as soon as the MSETCL transmission lines were connected. Tata Power started restoring supply to its consumers progressively from 12 noon onwards.

Tata Power regrets the inconvenience caused to its consumers due to this unforeseen event in power failure due to the transmission system failure leading to the cascading impact to all downstream suppliers of electricity including Tata Power, BEST and its consumers.”

The power supply in Mumbai will be fully restored in an hour, said a source.

The power outage was mainly because of a failure in the state grid and the city is supplied electricity under islanding system, the source told PTI.

Under islanding system, an area is supplied electricity in such a way that it is insulated from any grid failure or other technical issues happening outside that. 

The source also said that POSOCO has already charged up many electricity supply lines of the city and its suburbs.

Power Grid Corporation Ltd has no role to play as its main inter-state transmission lines were working perfectly, the source added.

Large parts of Mumbai and its suburbs faced a power failure due to which several trains have been held up.

Traffic signals in some areas were also not working.
