(Last updated Jan. 3, 2021, at 8:05 a.m. central time)
SPP returned to normal operations at 12:00 p.m. on Sunday, January 2, 2022, ending a Cold Weather Advisory that began 12:00 a.m. on Saturday, January 1, 2022.
SPP issues Weather Advisories when extreme weather is expected in SPP’s reliability coordination service territory. Weather Advisories do not require utilities or the public across our 14-state region to conserve energy. Individuals should contact their local utility for details specific to their area.
SPP will use the Grid Notice email exploder list to announce changing grid conditions in our footprint, including weather, resource and conservative operations advisories and energy emergency alerts.

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. 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.
