Current Grid Conditions

Current Grid Conditions

(Last update July 30 at 11:15 a.m. central time)
SPP declared a Resource Alert for its entire 14-state balancing authority (BA) footprint effective beginning July 26 at noon, and it has now extended that alert through 20:00 on Saturday, July 31. It was previously scheduled to expire at 00:00 on July 31. 

Additionally, SPP declared a period of Conservative Operations for its entire 14-state BA footprint effective 12:00 central time on Thursday, July 29 through 20:00 on Friday, July 30. The need for a declaration of Conservative Operations is due to hot-weather conditions, high electricity use, and concerns related to available generation capacity that are expected to persist through our afternoon peak on July 30.
