SPP is issuing a Resource Advisory for its entire Balancing Authority effective 11:00 a.m. CT – 8:00 p.m. CT Tuesday, May 14.

  • Resource Advisories do not require the public to conserve energy but are issued to raise awareness of potential threats to reliability among entities responsible for operating transmission and generation facilities.
  • The Resource Advisory is being declared for high peak loads due to potential low VER forecast during peak and planned resource outages.
  • To mitigate risks to reliability associated with these factors, SPP may use greater unit commitment notification timeframes, including making commitments before standard day-ahead market procedures and/or committing resources in reliability status.
  • SPP will send additional information if necessary.

SPP has extended the current Conservative Operations Advisory for the SPP Eastern Reliability Coordination (RC) footprint, which includes the entire SPP Balancing Authority, until an anticipated end time of 12:00 a.m.. CT on Monday, May 13.

In the region of the Western Interconnection where SPP serves as a RC, it has similarly extended the Conservative Operations Advisory to raise awareness among owners and operators of generation and transmission facilities.

  • Conservative Operations do not require the public to conserve energy but are issued to raise awareness of potential threats to reliability among entities responsible for operating transmission and generation facilities.
  • Conservative Operations is being extended due to a continued forecast of severe to extreme geomagnetic activity (also known as solar storms) with G4 conditions observed and G5 threshold possible, which may have impact to power and transmission systems. 
  • To mitigate risks to reliability associated with these factors, transmission operators are using heightened awareness of their transmission components. Owners and operators of generation and transmission facilities are to follow their own operating procedures for managing a geomagnetic disturbance event.
  • SPP will send additional information if necessary.

SPP is issuing a Conservative Operations Advisory for the SPP Eastern Reliability Coordination (RC) footprint, which includes the entire SPP Balancing Authority, effective 2:30 p.m. CT Friday, May 10 until an anticipated end time of 6:00 a.m. Saturday, May 11.

In the region of the Western Interconnection where SPP serves as a RC, it has similarly issued a Conservative Operations Advisory to raise awareness among owners and operators of generation and transmission facilities.

  • Conservative Operations Advisories do not require the public to conserve energy but are issued to raise awareness of potential threats to reliability among entities responsible for operating transmission and generation facilities.
  • Conservative Operations is being declared due to forecast of severe to extreme geomagnetic activity (also known as solar storms) with G4 conditions observed and G5 threshold possible which may have impact to power and transmission systems.
  • To mitigate risks to reliability associated with these factors, transmission operators are using heightened awareness of their transmission components. Owners and operators of generation and transmission facilities are to follow their own operating procedures for managing a geomagnetic disturbance event.
  • SPP will send additional information if necessary.

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.
