| Description: | This NPRR makes updates to language introduced by NPRR1149, Implementation of Systematic Ancillary Service Failed Quantity Charges, by providing the equations and the priority order to be used to consider Energy Storage Resource (ESR) Real-Time State of Charge (SOC) data when determining Ancillary Service Failed Quantity Charges for a Qualified Scheduling Entity (QSE) after each Operating Day. Under this NPRR, SOC insufficiencies will be reflected in adjustments to the telemetered Ancillary Service Resource Responsibilities for the ESR. These adjusted values will then be used in Ancillary Service failed quantity calculations for a QSE’s portfolio when performing the after-the-fact analysis. The adjusted Ancillary Service Resource Responsibilities for a QSE’s ESRs due to SOC insufficiency will be calculated separately for ‘Up’ and ‘Down’ Ancillary Services by the Energy Management System (EMS). These calculations will be used by the Market Management System (MMS) to allocate failed quantity charges at the QSE level for individual Ancillary Services. |
| Reason: | Strategic Plan Objective 1 |
