(a) on or before 31-03-2020, if the sustained deviation from schedule continues for 12 time blocks, the State Entity (buyer or seller), shall correct its position either by changing the sign of its deviation from schedule or by restricting the sustained deviation to the permissible limits as specified in Table-3 below with reference to its schedule for the time block to be reckoned for violation, at least once, latest by 13 th time block.
Table-3 Maximum permissible limits for Sustained Deviation from Schedule Sl.
No.
Schedule for relevant time block to be reckoned for violation Maximum permissible limits (in one direction of sustained deviation) in MW
1. Up to 10 MW 0.5
2. Upto 25MW 1.0
3. Upto 100MW 2.00
4. Above 100 MW 10.00
Provided that each violation of the requirement under this clause shall attract an additional charge of 10% on the time block DSM payable/ receivable as the case may be;
(b) on or after 01-04-2020, if the sustained deviation from schedule continues for 6 time blocks, the State Entity (buyer or seller), shall correct its position, either by changing the sign of its deviation from schedule or by restricting the sustained deviation to the permissible limits as specified in Table-3 above with reference to its schedule for the time block to be reckoned for violation, at least once, latest by 7th time block:
Provided that violation of the requirement under this clause shall attract an additional charge as specified in the table-4 below:
Table-4 Additional Charge for Violation in Sustained Deviation from Schedule:
No. of Violation in a Day Additional Change Payable From first to fifth violation For each violation, an additional charge @ 3% of daily base DSM ayable/receivable.
From sixth to tenth violation For each violation, an additional charge @ 5% of daily base DSM payable/receivable.
From eleventh violation onwards For each violation, an additional charge @ 10% of daily base DSM payable/receivable.
Provided further that counting of number of sign change violations under clauses
(a) & (b) of this Regulation shall start afresh at 00.00 Hrs. for each day:
Provided further also that payment of additional charge for failure to adhere to sign change requirement as specified under clauses (a) & (b) of this regulation shall not be applicable to—
(i) any infirm injection of power by a generating station prior to CoD of a unit during testing and commissioning activities, in accordance with the Connectivity Regulations; and 16 Compendium of HPERC Regulations, March 2021
(ii) any drawal of power by a generating station for the start-up activities of a unit.
Explanation.—For the purpose of this Regulation, sustained deviation means continuous deviation outside the maximum permissible limit as specified in Table-3 above, such range being a subset of the volume limit as specified in sub-regulations (1) and (2) of regulation 8. In other words, if the deviation is brought within the range as specified in Table-3 or it remains within the range specified in Table-3, it will not be considered as sustained deviation, even if the change in sign of deviation has not taken place.
Illustrations:—
(i) Illustration to clause (a) of this regulation.—A State Entity having a sustained deviation from time blocks t1 to t12, should correct its position either by changing the sign of its deviation (from positive to negative or negative to positive as the case may be) or come back in the permissible limits as specified in Table-3 above with reference to its schedule latest in the end of time block t13. In case, such sign change does not take place or it fails to come back in the range as specified in Table-3 above in the end of time block t13, but such correction of position takes place from time block t14 up to time block t24, then the additional charge shall be levied equivalent to one violation.
The above violation shall attract an additional charge at the rate of 10% of the time block DSM for t13. Further, in case, sign change does not take place or it fails to come back to the range as aforesaid even latest in the end of t25, but correction of position takes place from time block t26 up to time block t36, then the additional charge shall be levied equivalent to two violations. The above violation shall attract an additional charge at the rate of 10% of the time block DSM for t13 & t25, and so on.
(ii) Illustration to clause (b) of this regulation.—On or after 01-04- 2020, if a State Entity having a sustained deviation from time blocks t1 to t7, should correct its position either by changing the sign of its deviation (from positive to negative or negative to positive as the case may be) or come back in the range as specified in Table-3 above with reference to its schedule latest in the end of time block t7. In case, such sign change does not take place or it fails to come back in the aforesaid range in the end of time block t7, but such correction of position takes place from time block t8 up to time block t12, then additional charge shall be levied equivalent to one violation. Further, in case, sign change does not take place or it fails to come back in the range as aforesaid latest in the end of t13, but correction in position takes place from time block t14 up to time block t18, then the additional charge shall be levied for two violations and so on.
The additional charge shall be at the rate as specified in Table-4 above of this Regulation.
(iii) In case the State Entity effects change in the sign of its deviation from the schedule, or otherwise restricts the deviation to the permissible Compendium of HPERC Regulations, March 2021 17 limit as per Table-3, before the expiry of latest time block in which it was required to do so, the violations, if any, for the remaining period of the day shall be counted with reference to the time block in which it has actually complied the said requirement prior to the expiry of that time block.
(iv) The additional charge as per this regulation shall be computed on the sum total of the mode values (i.e. by ignoring the sign) of the amount payable and receivable for that day under regulation 7.]
