NPRR1178  Expectations for Resources Providing ERCOT Contingency Reserve Service

This Nodal Protocol Revision Request (NPRR) provides clarifications and updates regarding expectations for Resources providing ECRS. First, this NPRR provides clarity on expectations for Resource Status for Load Resources, other than Controllable Load Resources, when the Resource is providing ECRS simultaneously with Responsive Reserve (RRS). Under the current Protocols, the choice of Resource Status by the Qualified Scheduling Entity (QSE) may not be apparent. Second, to align with NPRR892, Non-Spin Reserve Energy Floor Clarification, this NPRR places an offer floor on capacity for Resources providing ECRS concurrently with On-Line Non-Spinning Reserve (Non-Spin). This change ensures that On-Line capacity for providing Non-Spin is priced above the $75/MWh offer floor. NPRR892 addressed this requirement for when a Resource is providing RRS and/or Regulation Up Service (Reg-Up) in addition to On-Line Non-Spin, however the timing of that NPRR was such that ECRS was not included in the proposed language. Lastly, this NPRR updates the ECRS deployment obligation requirements for Load Resources, other than Controllable Load Resources. The proposed language makes the requirement consistent with what will be in place with the implementation of Real-Time Co-optimization (RTC) of energy and Ancillary Services and states that any response to a deployment must remain in effect until recalled by ERCOT.
