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.
SPP will use the Grid Notice email exploder list to announce changing grid conditions in our footprint, including weather and resource alerts, conservative operations and energy emergency alerts.
