This Nodal Protocol Revision Request (NPRR) removes references to the provision of Responsive Reserve (RRS) across the Direct Current Ties (DC Ties). These references existed in the Zonal Protocols, and similar references have existed in the Operating Guides from at least 1997. However, to date, there are no ERCOT systems or procedures in place to award RRS 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.
