BackgroundFrom 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
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.
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:
