How It Works
Once you enroll, we’ll install a small, remote-controlled device on or near the central air conditioning (A/C) unit(s) of your choosing, absolutely free of charge. If we call an energy event in response to emergencies, high wholesale energy prices, or as part of testing, we’ll turn off (or cycle) your selected A/C’s compressor(s). These events may be called year-round. Your participation will earn you bill credits and help reduce the chance of power outages in your community. Your fan will continue to run and circulate air, so your customers and employees may not even notice a shift in temperature. But you’ll definitely notice the difference on your bill.
You Control the Settings and the Reward
With a variety of plans and options, SDP is completely customizable. You choose which unit(s) you want to enroll. Of course, the more units you enroll, the more bill credits you’ll earn.
- Must be enrolled in a qualifying rate plan
- Businesses enrolled in the Capacity Bidding Program (CBP) or the Time-Of-Use Base Interruptible Program (TOU-BIP) are not eligible

We’ve compiled the most common questions on the Summer Discount Plan to keep you informed.
During the summer season, you’ll see a monthly discount on your electric bill under the line item “A/C cycling discount.” Credits will appear on your billing statements monthly between June and October.
Your central A/C compressor may be cycled off for the following reasons:
- When the California Independent System Operator (CAISO) notifies us of the need to reduce electricity use in our service territory
- Upon determination by our grid control center of the need to implement load reductions in our service territory
- At our discretion when the CAISO has issued an Alert or Warning Notice
- When wholesale energy prices are high
- When we call test events to validate operating systems—test events do not require any specific system conditions before activation.
CAISO and we can call an event at any time, 24 hours per day, seven days per week, year-round. Each of your participating units may be cycled off up to a total of six hours per day. There can be multiple energy events in one day, but no event can be called after the six-hour daily limit has been exhausted.
No, only central A/C units that have cycling devices attached are affected during energy events. The rest of your business will have electricity, and your unit’s indoor fan may continue running to circulate the air, unless you let us know in advance that you prefer to have it turned off as well.
We offer courtesy alerts to let you know when an energy event is occurring in your area and your central A/C’s compressor is being cycled off. You can check to see if there are any events in progress. If your central A/C’s compressor unit is located where you can see the cycling device, the green LED light on the device will flash when your unit has been shut off.
If your central A/C’s compressor unit shuts off and the green LED light is not flashing, there may be several reasons why your central A/C’s compressor unit is not running:
- Thermostat or indoor fan is not set to the “on,” “cool,” or “automatic” position.
- Thermostat is not set low enough for the unit to come on.
- Condenser (outside unit) is dirty and obstructs air circulation.
- Filter is not clean.
- Circuit breaker is tripped or a fuse is blown at the meter or at the unit.
Caution: Before attempting to check or replace fuses, be sure to turn off the central compressor unit safety switch, which is located on or near the unit, in accordance with the manufacturer’s instructions.
You may also participate in other Demand Response programs, such as Summer Advantage Incentive. For more information, please contact your SCE account manager or visit sce.com/drp.
- Your current rate schedule;
- The size of your central air conditioner(s) being cycled – the greater the calculated tonnage, the larger the credit;
- The option you select – Maximum Savings (100%), Good Value (50%), or Maximum Comfort (30%); and
- The amount of electricity you use.
*The estimated savings assume a typical 5-ton central air conditioning unit, enrolled in the program from June 1 to October 1. Maximum credit amounts are subject to certain minimum usage requirements and vary by central air conditioner tonnage. Participation in Summer Advantage Incentive Program (formerly know as Critical Peak Pricing) may also reduce the maximum credit amounts. This program is not recommended for those with health problems, respiratory conditions or an inability to tolerate high temperatures. SCE is not responsible for any costs associated with receiving optional SDP courtesy alerts. See sce.com/TariffBooks for a complete list of terms and conditions of service. This program is funded by California utility customers and administered by SCE under the auspices of the California Public Utilities Commission.
