Critical Peak Pricing (CPP) for Businesses
A brief guide with facts, tips, and helpful answers.
Get to Know Critical Peak Pricing (CPP)
CPP is an optional rate that offers a discount on summer electricity rates in exchange for higher prices during 12 to 15 CPP event days per year, usually occurring on the hottest summer days. By reducing your electricity use during CPP events, you can lower your electric costs during the summer season — when your bills are typically the highest.
Here's How CPP Works
- 12 to 15 CPP events are called every year between 4 p.m. and 9 p.m. CPP events can be called year round any day of the week.
- Bill credits are applied during the summer months (June 1 – September 30) to reduce your power costs.
- Energy used during a CPP event is charged at a higher rate for the duration of the event.
- CPP event notifications are sent a day ahead of the event, so you can plan your usage. Go to sce.com/CPPupdatecontact to update or register your contact preferences for alerts.
Additionally, you can download and configure the SCE Demand Response (DR) Alerts mobile application to receive event-scheduled, event-start, and event-end notifications.

To help you determine if CPP is a good fit for your business, we’re offering our one-time Bill Protection guarantee for a full 12 months. With Bill Protection, we guarantee if you pay more during your first year on CPP, we’ll credit you the difference. You can choose to unenroll from CPP at any time. Keep in mind if you unenroll from CPP, you will not be able to make another change to your account for at least one year.

Tips for Reducing Energy Use on CPP Event Days
Here are some good energy-reducing practices to use during CPP events.
- 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 thermostat; pre-cool by setting the thermostat several degrees below your preferred temperature setting hours before the event begins
- Install sensory controllers on vending machines or shut them down for short periods of time
- Reduce production during CPP events or shift production to Off-Peak or Super Off-Peak hours (when CPP events will not occur)
- Unplug battery chargers and use only pre-charged equipment during On-Peak hours; charge battery-operated equipment prior to CPP events
- Turn off ice machines between 4 p.m. and 9 p.m.
A CPP Success Story
“It takes a lot of electricity to power 55 plants and 10 mine sites used to produce ready-mix concrete and construction aggregates for projects in California and parts of Nevada. That’s why Robertson’s Ready Mix works closely with SCE to determine ideal options in our service territory to reduce electricity use, lower operating costs, and minimize impacts on the environment.”
Rob Lesch, Electrical Manager
Robertson’s Ready Mix
Warehouses
- Pre-charge all-electric vehicles and battery-operated equipment before or after CPP event hours
Manufacturing and Food Processing
- Turn off motors, vertical lifts, conveyor belts, and nonessential process equipment
- Adjust schedules so energy-intensive production happens before and after CPP event hours
- Schedule batch or continuous processes before or after CPP event hours
Buildings
- Shut down unused rooms and facilities
- Install daylighting controls that let you adjust lighting levels
Retail
- Turn off unused, back-office equipment

You Have Questions. We Have Answers.
Frequently asked questions about CPP.
Is CPP right for my business?
If your business is able to reduce energy during CPP events, you may benefit from CPP. Use our Rate Plan Comparison Tool at sce.com/ratetool to compare your current rate costs with other rates to see if CPP is right for your business. Please note, that some rates are not available in the Rate Plan Comparison Tool.
How many events can be called and when?
CPP events can be called year-round, 12 to 15 times every calendar year any day of the week between 4 p.m. and 9 p.m. However, CPP events usually occur during the summer season on the hottest summer days.
What triggers a CPP event?
CPP events are usually called when electricity demand peaks due to extreme or unusual temperature conditions. Other triggers can include higher energy prices, electrical emergency alerts issued by the California Independent System Operator (CAISO), or an SCE system emergency that affects local grid operations. On these days, the costs of energy will increase during On-Peak demand times between 4 p.m. and 9 p.m.
Am I required to shut off power during a CPP event?
No. You are not required to completely shut off power during a CPP event. However, all-electric usage during an event will be charged at a rate significantly higher than normal.
Can a CPP event be canceled after it is called?
No. Once an event is called, it cannot be canceled.
How will I be notified if a CPP event is scheduled?
If you have signed up to receive notifications from SCE, we will notify you of a CPP event one day in advance. You can choose to receive an automated message from one of the following courtesy communications: phone, text, or email. You are responsible for keeping your contact preferences up to date with any changes. For added convenience, you can also use our SCE Demand Response (DR) Alerts mobile application. Have notices delivered straight to your smartphone when an event is scheduled, when it starts, when it ends, or all three.
How do I request courtesy CPP event notifications?
To receive CPP event notifications, visit sce.com/CPPupdatecontact to set up or update your contact preferences, or download and configure the SCE Demand Response (DR) Alerts mobile application (available for iOS and Android phones).
How can I confirm a CPP event is being called?
To check the status of active and historical events, visit the Demand Response Event Status at sce.com/drp/events or download and configure the SCE Demand Response (DR) Alerts mobile application.
Am I still responsible for the higher CPP energy charges during an event if I do not receive a notification?
Yes. Failure to receive a courtesy alert does not exempt you from reducing your energy use during an event, and you will be subject to paying higher charges for the duration of the event. You are responsible for setting up and keeping your contact preferences up to date.
Why does CPP only pay bill credits during the summer, even though an event may be called year-round?
The ability to call CPP events throughout the year gives us more flexibility to call upon needed resources. Credits are only applied from June 1 to September 30 to help offset the typically higher energy costs during the summer months.
Is my business eligible?
Most business customers receiving bundled service (delivery and generation of electricity) from SCE are eligible for CPP. If you’re a bundled business customer, your rate may already be enrolled on CPP.
How much energy are we using?
You may view your facility’s energy use with our online tool, My Account. Visit sce.com/myaccount to register.
Can I find out what SCE’s daily system peak was or find out what the peak demand forecast is for the next day?
SCE’s system load information is available on the OASIS page on the CAISO website, where you can view hourly system load and forecasts for each utility’s system within the CAISO control area.
