Maharashtra Power Distribution Company Ltd said the electricity crisis, which affected several parts of Mumbai on Thursday was due to a fault in Tata Power Company's station and not at MPDC's switchyard as claimed by TPC.
"We have not found any fault in our Koyna receiving station at Trombay and the way the TPC lines have collapsed, it shows that the fault was with their station," MPDC Director A D Palampar told PTI.
TPC was supplying about 200 MW power to Maharashtra state Electricity Board when the fault occurred following which the supply stopped, he said.
MSEB supplied about 500-600 MW of power to TPC after the tripping and the latter had to undertake a lot of load-shedding to bring the situation to normal.
Earlier, TPC had claimed that a technical snag in Koyna switchyard of Maharashtra State Electricity Board had affected the Trombay plant, and islanding system could not be employed, leading to power disruption at around 6:25 am.
Meanwhile, Reliance Energy, in a press release, said both units of its Dahanu Thermal Power Station continued to operate at the full capacity of 500MW and supplied power to its licensed area in Mumbai Suburbs.
"Reliance Energy, in addition to its own source, has to depend upon TPC to source the additional requirement of power to cater its area of supply. However, today (Thursday) a major breakdown in TPC's Generation system kept REL's area of supply without power and REL therefore was compelled to resort to load shedding," the release said.
