NOGRR156  Alignment with NPRR762, Removal of Language Related to Responsive Reserve Provided by DC Ties

This Nodal Operating Guide Revision Request (NOGRR) removes references to the provision of Responsive Reserve (RRS) across the Direct Current Ties (DC Ties). These references have existed in the Operating Guides since at least 1997, and similar language existed in the earliest versions of the Zonal Protocols. However, to date, there are no ERCOT systems or procedures in place to award Ancillary Services to the DC Ties, and no project to add this functionality has ever been proposed. Without any funding for the necessary system changes, ERCOT has no mechanism for allowing the provision of RRS over the DC Ties.
