Reason For Revision
 

Through the dispute process, an issue was identified where during HASP market disruption intervals, the IDS charge code was calculating penalties based on 0 HASP schedules.  The 0 values does not accurately represent the actual instructions followed by market participants.  The solution is to exempt HASP market disruption intervals from IDS penalty assessment.

 

  Inconsistencies between Tariff language and Settlement Configuration were identified.  The IDS quantity calculation for HB resources needed to be adjusted for it to be strictly the difference between HASP schedule and after-the-fact energy profile tag.  The IDS pricing logic of 75% of the greater between FMM and RTD LMP for when a resource accepts their award but does not deliver the energy is adjusted to only apply to under delivery.  Reliability Curtailment exemption is adjusted to only be applied to under delivery. 

 

The effective date of the changes is 2/1/2021 and the anticipated implementation date is 10/27/21.

Impact Analysis
Initial Comments
On 8/18/21 the CAISO received email question for PRR 1366. Pasting question and response here for transparency.

Questions:
This PRR states the CAISO is exempting HASP market disruption intervals from IDS Penalty Assessment. The PRR also says the effective date of the changes is 02/01/2021 and anticipated implementation is 08/19/2021. Does that mean they system automatically go back and recalculate any occurrences of this or will past instances of this still need to be disputed? If the answer is they will still need to be disputed, can we dispute all the way back to 02/01/2021?

Answer:
The CISO’s implementation for this change is effective starting 2/1/2021.  This means settlements will correct any instances of HASP market disruption for trade dates from 2/1 till implementation date (8/19).  We have a process in place to ensure all HASP market disruption intervals are identified and corrected,  therefore no disputes necessary.

Also, CC 6456 only impacts CISO resources.  EIM resources are not subject to IDS.
