Background
Extreme cold weather and precipitation affected the south central United States February 8-20, 2021. Many 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​.

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.

Phase 1 of the project ran from February – September 2022 and addressed the 4 Key Recommendations identified in the SAR. These standards were presented and approved by the NERC Board in October 2022. Phase 2 of the project began in October 2022 and is addressing the remaining Key Recommendations.

On February 16, 2023, FERC issued an Order Approving Extreme Cold Weather Reliability Standards EOP-011-3 and EOP-012-1 and Directing Modification of Reliability Standard EOP-012-1, N. Am. Elec. Reliability Corp., 182 FERC  61,094 (Feb. 16, 2023). In this order, FERC directed changes to be made to EOP-012-1.2
