Description: 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.
Reason: The 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.
