Alerts Status

SPP is issuing a Resource Advisory effective noon Tuesday, July 1

Monitoring - SPP is issuing a Resource Advisory for the entire Balancing Authority effective July 1, from noon until an anticipated end of 9 p.m. CT.
• 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.
• This Resource Advisory is being declared due to low variable energy resource (VER) forecast and outage uncertainty.
• Individuals should contact their local utility for details specific to their area.
• Generation and transmission operators have been provided instructions on applicable procedures, including reporting any limitations, fuel shortages or concerns.
• 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.
