Current Grid Conditions

(Last updated May 16, 2022, at 9:00 a.m. Central Time)

SPP's current grid condition is: Normal Operations for the entire region of the SPP Reliability Coordination (RC) East footprint effective at 8:00 p.m. CT Saturday, May 14, 2022.

SPP has issued a new Resource Advisory for the entire region of the SPP Reliability Coordination (RC) East footprint effective for 24 hours beginning at 12:00 a.m. CT Wednesday, May 18, 2022, with an anticipated end at 12:00 a.m. CT Thursday, May 19, 2022. Resource Advisories do not require the public to conserve energy.

This Resource Advisory is being declared due to higher than normal temperatures, load and wind forecast uncertainty, and system outages. 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.

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.
