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.
