- FERC-NERC-Regional Entity Joint Inquiry into Winter Storm Elliott: Key Findings and Recommendations Presentation
FERC and NERC staff, along with staff from NERC’s six regional entities, initiated an inquiry shortly after Winter Storm Elliott occurred. Though their final report itself will be published later this fall, the presentation provided to FERC on September 21st highlighted several key facts about the December 2022 event, including:
- There were unprecedented unplanned generating unit losses, with nearly 90,000 megawatts out at the same time.
- Nearly 80 percent of the generating units failed to perform at temperatures above their own documented minimum operating temperatures.
- Several electric grid operators had to shed firm load to maintain system reliability.
- Natural gas pipeline pressures dropped largely because of freeze-related production declines in production of Marcellus (23 percent) and Utica (54 percent) shales, as well as other natural gas infrastructure freeze- and equipment-related problems. Every cold weather inquiry report that has studied natural gas production has found cold-related declines in natural gas production, by as much as 70 percent in some cases.
- Consolidated Edison Inc., which serves the greater New York Metropolitan area, faced reliability-threatening low pressures on its delivery pipelines, forcing it to declare an emergency and use its own liquefied natural gas facility to maintain service.
The report outlines 11 recommendations for action to help prevent similar occurrences during future extreme winter weather. The recommendations cover cold weather reliability improvements for power generators, natural gas infrastructure, gas-electric coordination and electric grid operations.
