The Powergrid Corporation Ltd (PGCIL) has held seven major Indian states guilty of drawing more electricity than their allotted quota.
Uttar Pradesh, Gujarat, Maharashtra, Jammu and Kashmir, Haryana, Rajasthan and Punjab have all been found violating the Indian Electricity Grid Code (IEGC).
The Central Electricity Regulatory Commission (CERC) had directed PGCIL to furnish a list of such states, giving details of their quantum of overdrawals between October 9 and 15.
"The excessive withdrawals by these states made the Central Grid's frequency often fall below 49 Hertz, bringing the grid perilously close to collapse," said a PGCIL official who was involved in collecting the data. The report will be filed electronically to the CERC by Monday.
The constant maintenance of a satisfactory grid frequency has become all the more important after synchronisation of the Northern Regional Grid with the Central Grid, which comprises the Western, Eastern and North-Eastern Regional Grids.
The grid code requires that states should always try to restrict their net draw from the grid to their respective drawing schedules, whenever the system frequency is below 49.5 Hz. When the frequency falls below 49.0 Hz, load shedding to the extent required should be resorted to by states to prevent overdrawal.
CERC Chairman AK Basu said, "It has been brought to our notice that a number of states had resorted overdrawing power from October 9 to 15. This is dangerous, and we will take strict action against the violators. We are awaiting the report from PGCIL."
Added Power Secretary RV Shahi, "We have called meeting of energy secretaries of northern, western and southern states on Friday. Each of the states has to adhere to the IEGC, it is manageable problem if all the concerned follow the rules."
What is the code?
The Indian Electricity Grid Code lays down the rules, guidelines and standards to be followed by various agencies and participants in the system to plan, develop, maintain and operate the power system, while facilitating healthy competition in the generation and supply of electricity.
