[EDITOR’S NOTE: This story has been updated to reflect SPP’s conservative operations declaration Wednesday, June 22.]
SPP issued a resource advisory for its entire 14-state Eastern Interconnection footprint Monday because of higher-than-normal temperatures. The advisory is effective 4 p.m. CT on Tuesday and is expected to end at 8 p.m. Friday.
On Wednesday, the RTO upped the advisory in calling for conservative operations from 10 a.m. to 10 p.m. Wednesday. It said the advisory was declared because of high loads and wind generation’s availability.
Temperatures are forecasted to hit triple digits in Kansas, where heat stress has been blamed for the recent deaths of thousands of cattle.
The advisory does not require the public to conserve energy but does allow the RTO’s balancing authority to use greater unit commitment notification timeframes. That includes making commitments prior to day-ahead market and/or committing resources in reliability status.
SPP issues resource advisories when extreme weather, significant outages, and wind-forecast or load-forecast uncertainty is expected in its reliability coordination service territory. Generation and transmission operators have already been provided instructions on applicable procedures that include reporting any limitations, fuel shortages or concerns.
Conservative operations advisories are issued when weather, environmental, operational, terrorist, cyber or other events require the RTO to operate its system conservatively.
