Title: Access to Transmission Planning Information
Date Posted: 07/02/2024
Status: Approved on 01/16/2025
Description: This Nodal Protocol Revision Request (NPRR) moves from the Market Information System (MIS) Secure Area to the public ERCOT website reports that do not contain ERCOT Critical Energy Infrastructure Information (ECEII). ERCOT Staff analyzed reports in the MIS Secure Area, along with existing Protocols for posting requirements, and identified no ongoing basis for holding in the MIS Secure Area reports determined to contain only Transmission planning information for a market audience and not ECEII.
In addition to moving reports that do not contain ECEII to the ERCOT website, this NPRR also conforms rules with current posting practices for maintaining on the MIS Secure Area ECEII lists of equipment in the Outage Scheduler; for making available in the Model On Demand (MOD) application the annual planning model data submittal schedule; and for posting on the ERCOT website weekly Demand forecasts, demand analyses for 36 months and beyond, metrics of forecast error, and assessments of chronic congestion.
This NPRR also clarifies that the Technical Advisory Committee (TAC) publicly reviews the Major Transmission Elements (MTE) list that isn’t ECEII, rather than the High Impact Transmission Elements (HITE) list that is ECEII; that Private Use Network Load distribution factor data would be redacted from postings on the “ERCOT website” rather than on the “MIS”; and that ERCOT’s monthly evaluations of chronic congestion are posted on the ERCOT website. Finally, this NPRR strikes the requirement to post on the ERCOT website shift schedules for ERCOT Operations Staff – currently, ERCOT posts shift schedules redacted of individuals’ identifying information, making the postings of little or no public use.
