The Central Electricity Regulatory Commission (CERC) has sought detailed information on India's worst-ever power failure that occurred on 30-31 July last year from Power System Operation Corp. Ltd (Posoco) within the next fortnight.
Posoco, a subsidiary of transmission utility Power Grid Corp. of India Ltd, was formed in March 2010 to handle the power management functions of the transmission utility.
In an email to Posoco on 26 July 2012, Power Grid had requested for a shutdown of the 400 kilovolt Agra-Gwalior transmission line, apparently due to overload.
Power Grid had sent an e-mail to POSOCO on July 26, 2012 requesting for shut down of 400 kV Agra-Gwalior transmission line apparently due to likely overload.
The Commission has asked POSOCO whether there was a communication from Power Grid which led to revision of Total Transfer Capability (TTC) of the Western and the Northern region.
TTC is the amount of electric power that can be transferred over the interconnected transmission network in a proper manner.
CERC has also sought reasons from POSOCO for not imposing congestion charges on Punjab on July 30,2012, when the state's drawal was more than its ATC.
Available Transfer Capability (ATC) is a measure of the transfer capability remaining in the physical transmission network for further commercial activity over and above already committed uses.
CERC has sought clarification from Power Grid on the different setting adopted post disturbance and the basis for it and its implication, by May 15 this month.
The Commission has reserved its order on the suo moto petition on the grid failure, which occurred in July last year, plunging half of the nation into darkness and bringing essential services like trains and hospitals to a grinding halt.
The blackout in 20 states across north, eastern and north-eastern India affected more than 60 crore people and severely impacted train services.
