NPRR1108  ERCOT Shall Approve or Deny All Resource Planned Outage Requests

This Nodal Protocol Revision Request (NPRR) defines a process by which ERCOT will review, coordinate, and approve or deny all Resource Planned Outages, including those that are submitted more than 45 days prior to the planned start of the Outage. In conjunction with existing Protocol provisions, the addition of this process will allow ERCOT to meet the requirements of SB3 related to approval of all Planned Outages of electric generation. Specifically, the revisions: define a process for calculating a maximum MW of Resource Planned Outages that would be allowed for each day of the next rolling 60 months based on a capacity assessment; require that a Resource Planned Outage, or change to an approved Outage, submitted more than 45 days in advance of the planned start time of the Outage would no longer be “accepted” but would be approved on a first-come, first-served basis if the resulting aggregate Planned Outages are below the daily maximum MW for each day of the proposed Outage’s duration; require that a Planned Outage, or change to an approved Outage, submitted less than 45 days in advance of the planned start time of the Outage would be evaluated against the Maximum Daily Planned Resource Outage Capacity and for impacts on transmission reliability, taking into account previously approved Outages; describe that the determination of the Maximum Daily Planned Resource Outage Capacity for the next seven days uses same criteria as planning assessment for Outage Adjustment Evaluation (OAE); and make other minor changes and language clarifications (e.g. the inconsistent use of the terms “Outage plans” and “Outage schedules”).
