| Sections: | 6.5.7.2, 6.6.5.1.1.1, 6.6.5.1.1.2, 6.6.5.1.1.3, 6.6.5.1.1.4, 6.6.5.2, and 8.1.1.4.1 |
| Description: | This Nodal Protocol Revision Request (NPRR) proposes that Intermittent Renewable Resources (IRRs) carrying Ancillary Service Resource Responsibilities receive a Security-Constrained Economic Dispatch (SCED) Base Point calculated using the five-minute intra-hour forecast of the Resource. Generation Resource Energy Deployment Performance (GREDP) metrics are added to score performance during these intervals. Base Point Deviation Charges are adjusted to treat IRRs providing Ancillary Services the same as conventional generators. These changes cannot be done manually and will be active once a system change is implemented. This NPRR contains clean-up changes to correct the unit of measure for some billing determinants, and an as-built correction to the Settlement equation in paragraph (4) of Section 6.6.5.2. These clean-up changes do not introduce any system impact or Settlement changes. This NPRR also contains administrative edits to paragraphs (7) - (9) of Section 8.1.1.4.1, to align the paragraph numbering with current Protocol formatting style. These edits are authored as “ERCOT Market Rules” in this NPRR. |
