Summary

This Nodal Protocol Revision Request (NPRR) specifies the actions ERCOT will take to ensure sufficient Ancillary Service capacity exists in the event that ERCOT is unable to procure enough Ancillary Service capacity to meet its Ancillary Service Plan through the Day-Ahead Market (DAM). In summary, Supplementary Ancillary Service Market (SASM) and Houly Reliability Unit Commitement (HRUC) will be used, and in the event that Ancillary Service is still insufficient, Ancillary Service will be assigned to Qualified Scheduling Entities (QSEs) with Generation Resources based on available capacity. ERCOT’s intention is to keep this NPRR specific to ERCOT operational actions, with Settlement and other issues to be addressed in an additional NPRR submitted by Market Participants.
