ReasonThe current timeline creates unnecessary delays in the completion of a SASM. This slows the movement of Ancillary Services to other Resources should a unit trip or a transmission constraint not allow a QSE to provide Ancillary Services for which they are committed.

Summary

This Nodal Protocol Revision Request (NPRR) corrects the Supplemental Ancillary Services Market (SASM) to eliminate the notice periods when ERCOT needs to strike a SASM for Ancillary Services that are undeliverable or the result of a Qualified Scheduling Entity’s (QSE’s) failure to provide the service.
