Background

Status: Approved
Date Posted: Feb 26, 2020
Sponsor: ERCOT
Urgent: No
Sections: 2.1, 2.2, 3.2.6.2.2, 3.10.3.1, 3.10.7.2, 3.10.7.3, 3.10.7.5.2, 3.15, 3.15.1, 3.15.2, 6.5.7.7, 10.3.2.3, and 23K
Description: This Nodal Protocol Revision Request (NPRR) proposes the following revisions: • Revises the definition of Point of Interconnection (POI) to refer to any physical location where a Generation Entity’s Facilities connect to a Transmission Service Provider’s (TSP’s) Facilities, and removes references to Load interconnections, since the only relevant Load connection points are those associated with the Generation Entity’s generators, which are included in the term “Generation Entity’s Facilities.” • Introduces the term “Point of Interconnection Bus (POIB)” to refer to the Electrical Bus in the substation that is closest to the Generation Resource’s POI, or any electrically equivalent Electrical Bus in that substation, for each TSP-owned substation to which the Generation Resource interconnects. • Changes POI to POIB throughout the Protocols in appropriate cases based on the above clarifications. • Removes the reference to POI in Section 2.1 in the definition of Aggregate Generation Resource because having a common Generator Step Up (GSU) transformer would aggregate output before the POI, and the generators’ separate outputs do not have separate POIs. • Clarifies Section 10.3.2.3 to specify that, at a given Generation Resource Facility, generation and associated Load must either be physically metered at each POI or Service Delivery Point, or loss-compensated to the applicable POI in accordance with Section 10.3.2.2. • Adds NPRR917, Nodal Pricing for Settlement Only Distribution Generators (SODGs) and Settlement Only Transmission Generators (SOTGs), greyboxed language to Section 10.3.2.3 and removes the greybox, as there is no system implementation required for language in Section 10.3.2.3. • Removes POI from Section 23, Form K because it is used there incorrectly.
Reason: Addresses current operational issues; Market efficiencies or enhancements
