action against the seller/buyer for all such violations as per the provision of Section 146 of the Act.

(K) Sustained Deviation Charges:

In the event of sustained deviation from schedule in one direction (positive or negative) by any state entity,

such state entity (buyer or seller), shall correct its position in the manner as specified under clause (a) and

(b) of this Regulation.

(a)

For the period upto 30.11.2020: If the sustained deviation from schedule continues in one direction

(positive or negative) for 12 time blocks, the state entity (buyer or seller) shall 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 13th time block, such range being a subset of the volume

limit as specified under Regulation 10 of these Regulations;

Provided that each violation of the sign change requirement under this clause shall attract an additional

charges of 10% of the time block DSM Charges payable or receivable as the case may be.

To illustrate,

A state entity having a sustained deviation from time blocks t1 to t12, shall 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 of +/- 20 MW with reference to its schedule, latest by the end of time block

t13. In case, such sign change does not take place or it fails to come back in the range of +/- 20 MW by

the end of time block t13, but such correction of position takes place from time block t14 up to time

block t24, then 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 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,

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,

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.

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
