Implementation Plan


Background
From February 8 - 20, 2021, extreme cold weather and precipitation affected the south central United States. Large numbers of generating units experienced outages, derates, or failures to start, resulting in energy and transmission emergencies (referred to as “the Event"). The total Event firm load shed was the largest controlled firm load shed event in U.S. history and was the third largest in quantity of outaged megawatts (MW) of load after the August 2003 northeast blackout and the August 1996 west coast blackout.

Standard(s) Affected  – BAL, EOP, IRO, TOP, or Other Standards as Identified in the SAR​​​

Purpose/Industry Need
The primary purpose of this project is to address reliability related findings from the Federal Energy Regulatory Commission (FERC), NERC, and Regional Entity Joint Staff Inquiry into the February 2021 Cold Weather Grid Operations1. The project scope will address nine recommendations for new or enhanced NERC Reliability Standards proposed by the report.

The NERC Board of Trustees (Board) issued a resolution in November 2021 for the development of standards under this project be completed in accordance with the staged timelines recommended by the joint inquiry team, as follows​:

  • New and revised Reliability Standards to be submitted for regulatory approval before Winter 2022/2023: development completed by September 30, 2​​022 for the Board's consideration in October 2022;
  • New and revised Reliability Standards to be submitted for regulatory approval before Winter 2023/2024: development completed by September 30, 2023 for the Board's consideration in October 2023.
