Get to know critical
peak pricing (CPP).

In March 2019 (pending CPUC approval), many small and medium businesses and large agricultural and pumping businesses will be 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 between 4 p.m. and 9 p.m., usually occurring on the hottest summer days. By reducing your electricity use on CPP event days, you can lower your electric costs during the summer season—when your bills are typically the highest. CPP is an optional rate, and you have an opportunity to opt out of CPP before automatically transitioning in March 2019 (pending CPUC approval).

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

Who is affected?

Businesses with service accounts under 200 kW (Rate Schedules TOU-GS-1 and TOU-GS-2)

Agricultural and Pumping customers with service accounts over 200 kW (Rate Schedule TOU-PA-3)

You can choose a rate without CPP at any time.

You can compare all your rate options below, but before you do, check out how CPP works. The program could actually lower your energy bill.

For the first 12 months, we’ll guarantee you won’t pay more than if you had never enrolled.

Here’s how CPP works:

  1. 1If you’ve signed up for notifications, you’ll get a notification that we have announced a CPP event for the following day. You can receive your notification by your choice of phone call, text, or email. CPP events can occur year-round only on non-holiday weekdays.
  2. 2The 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.

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.
  • Turn off ice machines between 4 p.m. and 9 p.m.

A CPP Success Story

“We lowered our electric bill by enrolling in the Critical Peak Pricing program and reducing our energy usage during CPP event hours. We received $11,300 in incentives in 2014 and nearly $15,000 in 2015.”

Time-Of-Use (TOU) periods are changing too.

TOU periods will change as of March 2019 (pending CPUC approval) to align prices with the cost of generating and delivering electricity based on the time, day, and season.

If your business is able to reduce energy during CPP events, you may benefit from CPP.

CPP events can be called year-round, 12 times per calendar year on non-holiday weekdays 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.

To check the status of active and historical events, visit the Demand Response Event Status at 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 rate plan may be already combined with CPP.
