NOTICE TYPE: W-A041824-01 Operations

SHORT DESCRIPTION: Request for known outages to address NERC Reliability Standard TPL-001

INTENDED AUDIENCE: NERC-registered Generator Owners (GOs) and Generator Operators (GOPs) and ERCOT-registered Resource Entities (REs)

DAYS AFFECTED: May 3, 2024

LONG DESCRIPTION: NERC Reliability Standard TPL-001 requires Planning Assessment studies to include “known outage(s) of generation or Transmission Facility(ies)."

To address this requirement, ERCOT requests that each NERC-registered GO and GOP and each ERCOT-registered RE identify known outages of equipment (including, but not limited to, generators, transmission lines, transformers, and series or shunt devices) for study years 2026 through 2030 and provide this information to ERCOT. For each outage, each entity should include the projected start and stop dates and times of the outage, and the reason for the outage.

ERCOT uses this information in the creation of study models for its Planning Assessment. Please note that Requirements 2.1.4 and 2.4.4 of TPL-001-5.1 state, “Known outage(s) shall not be excluded solely based upon outage duration.” 

ACTION REQUIRED: By May 3, 2024, each NERC-registered GO and GOP and each ERCOT-registered Resource Entity shall provide a written response to this request identifying known outages of generation Facilities for study years 2026 through 2030. Please send responses to ERCOT via email at RTP@ercot.com
