NOTICE DATE: April 18, 2024
NOTICE TYPE: W-B041824-01 Operations
SHORT DESCRIPTION: Request for known outages to address NERC Reliability Standard TPL-001
INTENDED AUDIENCE: NERC-registered Transmission Owners (TOs) and Transmission Planners (TPs) and ERCOT-registered TDSPs
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 TO and TP and each ERCOT-registered TDSP identify known outages of equipment (including, but not limited to, 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 provide the study year that the outage is projected to be active and indicate whether the outage will affect the summer peak timeframe (for study years 2026 through 2030), the Off-Peak timeframe (for study year 2027), and/or the winter peak timeframe for study year 2029. Each entity should also provide a technical rationale for the selection of the outages it submits.
ERCOT will use 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 TO and TP and each ERCOT-registered TDSP shall provide a written response to this request identifying known outages of Transmission Facilities for study years 2026 through 2030. Please send responses to ERCOT via email at RTP@ercot.com
ADDITIONAL INFORMATION: Please provide requested information in the 2024RTP_TransmissionKnownOutageTemplate attachment along with the technical rationale for the selection of the outages.
