The lingering heat wave prompted the Southwest Power Pool, Oklahoma’s power grid operator, to issue a Resource Advisory this week but it does not require consumers to conserve energy.
The advisory covers SPP’s 14-state footprint and was to be effective at 4 p.m. Central Time on Tuesday, June 21 with an anticipated end at 8 p.m. CT Friday, June 24 according to the announcement.
The Power Pool explained the Advisory was declared due to higher than normal temperatures as a heat wave blankets much of the Midwest with temperatures into the mid to upper 90s and lower 100s.
As a result, the SPP Balancing Authority may use greater unit commitment notification timeframes, including making commitments prior to Day-Ahead Market and/or committing Resources in Reliability Status.
SPP issues Resource Advisories when extreme weather, significant outages, wind-forecast uncertainty and/or load-forecast uncertainty are expected in SPP’s reliability coordination service territory. Generation and transmission operators have been provided instructions on applicable procedures, including to report any limitations, fuel shortages or concerns.
SPP will send additional information if necessary. Resource Advisories do not require the public across our 14-state regional transmission organization (RTO) region to conserve energy. Individuals should contact their local utility for details specific to their area.
SPP’s last change in status was at 8:00 p.m. CT Saturday, May 14, 2022, when it ended a Resource Advisory that had been in effect since 12:00 p.m. CT Friday, May 13, 2022, during a period of higher than normal temperatures, wind forecast uncertainty and system outages.
