Texans could face another extreme cold snap this winter, ERCOT officials warned, noting that while the state grid has improved, severe weather could still lead to rotating power outages.
The Electric Reliability Council of Texas (ERCOT) cautioned on Monday that Texans should brace for another potential extreme cold snap this winter, similar to the severe Winter Storm Uri experienced in February 2021.
Chris Coleman, ERCOT's lead meteorologist, informed the board that conditions are conducive to "something like a Uri," although this winter is anticipated to be warmer than usual. “It resembles a tornado watch,” Coleman remarked. “The conditions exist, yet it does not ensure that it will occur.”
Recent trends indicate that extreme cold events are occurring more frequently in Texas. From 1991 to 2016, only three winter storms brought temperatures down to critical lows in Dallas, Austin, and Houston. However, since 2016, there have been five such events.
ERCOT emphasized ocean temperatures and atmospheric patterns resembling those observed prior to Winter Storm Uri as elements causing concern. Improved grid preparations involve fortified power plants and transmission facilities; however, the possibility of rotating outages persists.
ERCOT models indicate almost a 50% likelihood of power outages if Texas faces weather similar to the December 2022 freeze. “You can experience a mild winter while still encountering severe cold,” Coleman added.
Residents are encouraged to remain informed and ready for possible weather disruptions as the state works on enhancing its power infrastructure resilience.
