Get to Know Critical Peak Pricing (CPP)
CPP is the default option for small, medium, and large business customers (Rate Schedules TOU-GS-1, TOU-GS-2, TOU-GS-3, and TOU-8) as well as large Agricultural and Pumping (Rate Schedule TOU-PA-3) customers. CPP provides four months of summer season bill credits in exchange for paying higher electricity prices during 12 to 15 annual CPP events. When called, CPP events are from 4 p.m. to 9 p.m., usually occurring on the hottest summer days. If your business reduces its electricity use when we notify you of CPP events, you can minimize these higher prices. Plus, your business will earn credits on your electricity bills during the summer season — when your bills are typically the highest.
Save More with the Technology Incentive Program
If you are enrolled in Critical Peak Pricing, you could get $75 back when you register your qualifying smart thermostat in the Technology Incentive Program.
During a CPP event, we will notify your smart thermostat provider to temporarily adjust the temperature setting on your thermostat to limit A/C usage at your business. You will always have the ability to adjust the temperature during these events, but this could affect your CPP event charges.

Here’s how CPP works:
1. If you’ve signed up for notifications, you’ll be notified a day before a CPP event occurs. You can receive your notification by your choice of phone call, text, or email. CPP events can occur year-round any day of the week. You can receive event scheduled, event start, and event stop notifications by downloading and configuring the SCE Demand Response (DR) Alerts mobile application.
2. 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.

Tips to Reduce Energy Use During a CPP Event
Your business will not have to shut down operations to participate in CPP events. Instead, these tips can help reduce your energy usage 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.
CPP Success Stories
"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, Robertson’s Ready Mix Electrical Manager
If your business is able to reduce energy during CPP events, you may benefit from CPP. CPP events are called 12 to 15 per calendar year on any day of the week between 4 p.m. and 9 p.m.
CPP events can be called year-round, 12 to 15 times per 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.
CPP events are usually called when electricity demand peaks due to extreme or unusual temperature conditions. Other triggers can include high energy prices, electrical emergency alerts issued by the California Independent System Operator (CAISO) or a SCE system emergency that affects local grid operations. On these days, the cost of energy will increase during On-Peak demand times between 4 p.m. and 9 p.m.
No. You are not required to reduce electric load during a CPP event. However, all electric usage during a CPP event will be charged a significantly higher rate than normal.
No. Once a CPP event is called it cannot be canceled.
If you’ve signed up for notifications, 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.
You can also have notices delivered straight to your smartphone, when an event is scheduled, when it starts, when it ends, or all three by downloading the SCE Demand Response (DR) Alerts mobile application.
To check the status of active and historical events, visit the Demand Response Event Status at sce.com/drp/events or download the SCE DR Alerts mobile app.
Yes. Failure to receive a courtesy alert does not exempt you from reducing your energy use during an event, and you will be paying higher charges for the duration of the event. You are responsible for keeping your contact preferences up to date with any changes.
The ability to call CPP events throughout the year gives SCE 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 summer months.
Most business customers receiving bundled service (delivery and generation of electricity) from SCE are eligible to participate in CPP. If you’re a bundled business customer, your account may be already be on a CPP.
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.
