Grid Disturbances on 30th and 31st july, 2012 due to
Multiple Factors
The Minister of State, Shri K.C. Venugopal, in a written reply informed the Rajya Sabha today that the Enquiry Committee constituted to enquire into the grid disturbances has come to the conclusion that no single factor was responsible for the grid disturbances on 30th and 31st July, 2012. The Committee has concluded that the disturbances were caused by a combination of factors, inter-alia, weak inter-regional corridors due to multiple outages, high loading on 400 kV Bina-Gwalior-Agra link, inadequate response by State Load Despatch Centres (SLDCs) to the instructions of Regional Load Despatch Centres (RLDCs) to reduce overdraw, loss of 400 kV Bina-Gwalior link. On 31st July, 2012, apart from the aforementioned reasons, the system was weakened by outages of transmission lines in the Eastern Region network near Eastern – Western Region interface. The minister further informed that irrespective of the recent grid collapse, Central Electricity Regulatory Commission (CERC) has been initiating action under Sections 142 and 143 of the Electricity Act, 2003, against the States for violating the grid discipline by overdrawing more power and not adhering to the drawal of power as per their schedule.
