The scheduling and despatch code thereon shall be governed by following principles:

i. Based on the availability given by generators (Sellers) and load requirement forecasted by Buyers, the SLDC shall draw up the least cost despatch schedule on Day Ahead basis for the State Entities in accordance with the merit order principles as specified in State Grid Code or the guidelines as may be approved by the Commission separately, if required, in accordance with the State Grid Code.

ii. Wheeling transactions of captive users and open access consumers shall be despatched as contracted, subject only to transmission constraints and system emergency conditions.

The above violation shall attract an additional charge at the rate of 10% of the time block DSM charge for t13. Further, in case, sign change does not take place or it fails to come back in the range as aforesaid latest by the end of t25, but correction in position takes place from time block t26 up to time block t36, then the additional charge shall be levied for two violations and so on.

(b) For the period from 01.12.2020 onwards: If the sustained deviation from schedule continues in one direction (positive or negative) for 6 time blocks, the state entity (buyer or seller), shallPUNJAB GOVT. GAZ. (EXTRA), SEPTEMBER 10, 2020 (BHDR 19, 1942 SAKA) 1299 correct its position, by making the sign of its deviation from schedule changed or by remaining in the range of +/- 20 MW with reference to its schedule, at least once, latest by 7th time block, such range being a subset of the volume limit as specified under Regulation 10 of these Regulations;

Provided that violation of the requirement under clause (b) of this Regulation shall attract an additional charge as specified in the table below:

No. Of violations in a day Additional Charge Payable

From first to fifth violation For each violation, an additional charge @3% of the daily base DSM

charge payable or receivable

In case, such sign change does not take place or it fails to come back in the aforesaid range by the end of time block t7, but such correction of position takes place from time block t8 up to time block t12, then an 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 by 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;

Note:-

i. The Deviation Settlement Mechanism (DSM) rate vector will have a dynamic slope determined by joining the identified price points at 50 Hz. (daily simple average ACP), frequency of 49.85 Hz (Rs. 8 per unit) and 50.05 Hz (zero) on a daily basis.

ii. The maximum ceiling limit applicable for average Daily ACP discovered in the DAM segment of Power Exchange at 50.00 Hz shall be 800 Paise/kWh.

iii. Charges for deviation for each 0.01 Hz step shall be equivalent to the Slope determined by joining the price at 'Not below 50.05 Hz' and 'identified price at 50.00 Hz' in the frequency range of 50.05-50.00 Hz, and to the Slope determined by joining the 'price identified at 50.00 Hz' and price at 'below 49.85 Hz' inPUNJAB GOVT. GAZ. (EXTRA), SEPTEMBER 10, 2020 (BHDR 19, 1942 SAKA) 1305 frequency range 'below 50 Hz' to 'below 49.85 Hz'.

iv. The daily simple average ACP of the Power Exchange having a market share of 80% or more in energy terms on a daily basis shall be taken into consideration for linking to the DSM price vector. If no single Power Exchange is having a market share of 80% or more, the weighted average day-ahead price shall be used for linking to the DSM price.

v. The daily simple average Area Clearing Prices (ACP) in the day-ahead market (exclusive of any transmission charges and transmission losses) shall be used as the basis for market linked DSM price at 50 Hz.

Provided that based on a review of the above mechanism within one year or in such time period as may be decided by the Commission, if the Commission is satisfied that the market conditions permit, the basis for market linked DSM price shall be substituted, by the time-block-wise ACP in the day ahead market or as and when the real time market is introduced, by the hourly ACP or the ACP of such periodicity as may be considered appropriate by the Commission.

vi. In case of non-availability of the daily simple average ACP due to no-trade on a given day, daily simple average ACP of the last available day shall be considered for determining the DSM charge.

vii. Deviation price shall be rounded off to nearest two decimal places

viii. An illustration to DSM price vector specified in table above, is provided as Annexure-III

The National Load Despatch Centre (NLDC) shall act as the Nodal Agency to declare the daily DSM rates and shall display all relevant information on its websitePUNJAB GOVT. GAZ. (EXTRA), SEPTEMBER 10, 2020 (BHDR 19, 1942 SAKA) 1306
