MUMBAI: Another grid failure, this time sparked off in Madhya Pradesh, led to a temporary loss of power in parts of Maharashtra on Wednesday.
A spokesperson for Mahavitaran said that at 1.12 p.m., the Chandrapur Parli-2 line tripped and subsequently the Koradi-Bhusawal line also tripped.
The utility reported a generation loss of over 2000 MW, from three units of 500 MW each from Chandrapur, one unit of 110 MW from Koradi and all units of Bhusawal, about 600 MW.
However, power from the Koyna hydro-project of about 1500 to 1600 MW saved the situation. To make up for the loss in power, some extra partial load shedding was resorted to.
The power supply was affected when the 400 Kv Itarsi Khandwa line in Madhya Pradesh tripped, causing the lines in Maharashtra to trip on power swing.
All affected generating units were commissioned by 4.30 p.m. and normality was restored.
The situation was not as bad as that of February 25, when western Maharashtra, Konkan and parts of Mumbai had a blackout for over five hours.
A one-man committee, comprising Shishir Tamotia, director, operations, Mahatransco, was appointed to inquire into last Sunday's grid failure. He will submit a report on Thursday, according to the spokesperson for Mahavitaran.
The Maharashtra Electricity Regulatory Commission (MERC) had issued notices to Mahatransco, asking it to explain Sunday's power failure.
