Summary
This Nodal Protocol Revision Request (NPRR) develops a stand-alone Dispatchable Reliability Reserve Service (DRRS) product that includes the following functionality: DRRS is added to the Protocols on top of Real-Time Co-optimization (RTC) and Energy Storage Resource (ESR) single-model Protocols; DRRS is offered, awarded, and paid in the Day-Ahead Market (DAM). DRRS is not co-optimized in the Real-Time Market (RTM); DRRS can be-self arranged and traded. However, there are no DRRS-only offers (i.e., virtual DRRS offers) allowed, as DRRS will not be co-optimized in Real-Time; DRRS can be provided by Off-Line Generation Resources; a new Resource Status code will be developed for Resources with an Ancillary Service Resource Responsibility for DRRS that have not been deployed by ERCOT; When looking to commit capacity during the Reliability Unit Commitment (RUC) process, RUC will give priority to committing Off-Line Generation Resources providing DRRS. This is accomplished because Off-Line DRRS Resources will appear to have lower start-up and minimum energy costs relative to other Off-Line Generation Resources in the RUC optimization; DRRS will have a failure-to-provide Settlement for Qualified Scheduling Entities (QSEs) that do not sufficiently preserve Resource capability for providing DRRS within their portfolio; DRRS deployments will be included in the Reliability Deployment Price Adder process, in alignment with other existing Protocol language for similar deployments; and QSEs that are short on their DRRS Supply Responsibility at the time of a RUC instruction will be allocated a portion of any RUC Make Whole charges prior to allocating those costs to the QSEs that are RUC Capacity Short.
