FERC Staff Recommends Natural Gas Infrastructure Winterization Measures in Light of 2021 Extreme Winter Weather Events
The Federal Energy Regulatory Commission (“FERC”), in coordination with the North American Electric Reliability Corporation (“NERC”), presented its preliminary findings and recommendations at FERC’s Open Meeting on September 23 regarding its inquiry into the February 2021 Cold Weather Event in the Electric Reliability Council of Texas (“ERCOT”), Southwest Power Pool, Inc. (“SPP”), and Midcontinent Independent System Operator, Inc. (“MISO”).
The February 2021 Cold Weather Event occurred from February 8 through 20, 2021, during which large numbers of generating units experienced outages, derates, or failures to start, resulting in energy and transmission emergencies. The power outages affected millions of customers throughout the ERCOT, MISO, and SPP regions. On February 16, 2021, FERC and NERC announced a joint inquiry to examine the root causes of the event.
The preliminary findings indicate that a majority of the unplanned generating unit outages, derates, and failures to start were due to natural gas fuel supply issues. The major causes of the decline in natural gas
