NOTICE TYPE: M-A120220-01 NERC
SHORT DESCRIPTION: Request for known outage(s) with a duration of at least six months to address NERC Reliability Standard TPL-001-4
INTENDED AUDIENCE: NERC Transmission Owners (TOs), Transmission Planners (TPs), Generator Owners (GOs), and Generator Operators (GOPs)
DAY AFFECTED: December 17, 2020
LONG DESCRIPTION: Requirement 1.1.2 of NERC Reliability Standard TPL-001-4 provides that System models shall represent “known outage(s) of generation or Transmission Facility(ies) with a duration of at least six months."
To address this requirement, ERCOT requests that each TO/TP/GO/GOP identify known outage(s) of equipment (including, but not limited to, generators, transmission lines, transformers, and series or shunt devices) with a duration of at least six months for study years 2022 through 2027. Each TO/TP/GO/GOP should identify 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 2022 through 2027) and/or the Off-Peak timeframe (for study year 2024). ERCOT will use this information in the creation of study models for its Planning Assessment.
ACTION REQUIRED: By December 17, 2020, each TO/TP/GO/GOP shall provide a written response identifying the known outage(s) of generation or Transmission Facility(ies) with a duration of at least six months for study years 2022 through 2027. If no outages of generation or Transmission Facility(ies) have been identified with a duration of at least six months, the TO/TP/GO/GOP should so state in the written response. Please send responses to ERCOT via email at [log in to unmask].
