Current Grid Conditions

(Last updated June 22, 2022, at 8:45 a.m. Central Time)

SPP has declared Normal Operations for its entire 14-state Balancing Authority footprint in the eastern interconnection effective at 10 p.m. CT Wednesday, June 22, 2022.

This ended the declaration of Conservative Operations from 10:00 a.m. CT June 22. It also ended the declaration of a Resource Advisory from 4:00 p.m. CT, June 21, that had been expected to continue through 8:00 p.m. CT, June 24. Capacity outlook throughout the region improved with an expected increase in wind forecast.

SPP issues Conservative Operations Advisories when SPP there is a need to operate its system conservatively based on weather, environmental, operational, terrorist, cyber or other events. Generation and transmission operators have been provided instructions on applicable procedures, including to report any limitations, fuel shortages or concerns. Conservative Operations 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 10:00 a.m. CT Tuesday, June 22, 2022, when it declared a Conservative Operations Advisory for its entire 14 state balancing authority during a period of higher than normal temperatures, wind forecast uncertainty and system outages.

Descriptions of common reliability events are provided below in increasing order of severity:

Advisories raise awareness and do not require general audiences to take action. SPP member utilities should follow applicable procedures. Energy Emergency Alerts indicate all available generation has been committed to meet region-wide demand. As conditions worsen, voluntary conservation or service interruptions may be necessary to prevent uncontrolled outages.

Normal Operations: SPP has enough generation to meet demand and available reserves, and it foresees no extreme or abnormal threats to reliability.

Weather Advisory: Declared when extreme weather is expected in SPP’s reliability coordination service territory.

Resource Advisory:  Declared when severe weather conditions, significant outages, wind-forecast uncertainty and/or load-forecast uncertainty are expected in SPP’s balancing authority area.

Conservative Operations Advisory:  Declared when SPP determines there is a need to operate its system conservatively based on weather, environmental, operational, terrorist, cyber or other events.

Energy Emergency Alert Level 1:  Declared when all available resources have been committed to meet obligations, and SPP is at risk of not meeting required operating reserves.

Energy Emergency Alert Level 2:  Declared when SPP can no longer provide expected energy requirements, or when SPP foresees or has implemented procedures up to, but excluding, service interruptions to maintain regional reliability. 

Energy Emergency Alert Level 3:  At this level, SPP is utilizing operating reserves such that it is carrying reserves below the required minimum and has initiated assistance through its Reserve Sharing Group. SPP foresees or has implemented firm load obligation interruption. Before requesting an EEA 3, SPP will have already provided the appropriate internal notifications to its Market Participants.

Restoration Event:  Defined as a major or catastrophic grid outage which could be a total or partial regional blackout, island situation or system separation.
