Background
| Status: | Approved |

| Date Posted: | Oct 13, 2020 |
| Sponsor: | ERCOT |
| Urgent: | No |
| Sections: | 3.2.3 |
| Description: | This Nodal Protocol Revision Request (NPRR) changes certain reports required by Section 3.2.3 from being aggregated “by Load Zone” to being aggregated “by Forecast Zone.” “Forecast Zones”, which have the same boundaries as the 2003 ERCOT Congestion Management Zones (CMZs), consist of North, South, West, and Houston. NPRR978, Alignment with Amendments to PUCT Substantive Rule 25.505, which was approved by the ERCOT Board on February 11, 2020, revised paragraphs (3)(a), (b), (c), (g), and (h) of Section 3.2.3, which relates to short-term adequacy reports, to reflect the requirement in amended item (d) of P.U.C. SUBST. R. 25.505, Reporting Requirements and the Scarcity Pricing Mechanism in the Electric Reliability Council of Texas Power Region, that information concerning Resource availability be aggregated by Load Zone. However, during implementation planning for NPRR978, it was determined that if these reports were aggregated by Load Zone, it could enable the identification of capacity information for certain Resources that are part of Non-Opt-In Entity (NOIE) Load Zones. Aggregation by Forecast Zone aligns with current ERCOT disclosure report aggregation practice (see Section 3.2.1, Calculation of Aggregate Resource Capacity) and will comply with item (d) of P.U.C. SUBST. R. 25.505 while also protecting against the disclosure of commercially sensitive information. |
