Critical Peak Pricing

A manager makes a phone call from a warehouse.

Get To Know Critical Peak Pricing (CPP)

In March 2019, many small and medium businesses and large agricultural and pumping businesses were automatically enrolled on Critical Peak Pricing (CPP). CPP is already the default option for large businesses (Rate Schedules TOU-GS-3 and TOU-8). CPP offers a discount on summer electricity rates in exchange for higher prices during 12 CPP event days per year called between 4 p.m. and 9 p.m., usually occurring on the hottest summer days. By reducing your electricity use when we notify you of CPP events , you can lower your electric costs during the summer season—when your bills are typically the highest. 

If your business is able to reduce its energy use away from CPP events, you can lower your overall costs.

Here’s how CPP works:

 If you’ve signed up for notifications, you’ll get a notification thatwe have announced a CPP event for the following day. You canreceive your notification by your choice of phone call, text, or email. CPP events can occur year-round only on non-holiday weekdays.

 The next day, during the CPP event, you should lower your usage between 4 p.m. and 9 p.m. because you will be charged at a significantly higher rate than normal for all usage during these hours.

                                   Weekdays Only

                                (Summer and Winter)

Tips to Reduce Energy Use During a CPP Event


  • Turn off all nonessential indoor/outdoor lighting, signage, window displays, fountains, and office equipment not in use.
  • Raise cooling thermostat settings to 78°F with a programmable smart thermostat.
  • Install sensory controllers on vending machines to shut them down for short periods of time.
  • Reduce production during CPP events or reschedule during Off-Peak or Super Off-Peak hours (when CPP events will not occur).
  • Unplug battery chargers and use only precharged equipment during On-Peak hours; charge battery-operated equipment prior to CPP events.
