MidAmerican Energy's EnergyAdvantage® SummerSaver program allows you to do your part to save energy by allowing us to control the operation of your home air conditioner when the demand for electricity is highest. By reducing peak demand, we're able to provide energy more efficiently and reliably.

Single-family owner-occupied homes in South Dakota with a central air conditioning unit or air-source heat pump may be eligible.

Here's How it Works
MidAmerican Energy installs a small cycling device on the siding of your home near the central air conditioning unit. From June 1 to Sept. 30, the device will cycle your air conditioner on and off only on the hottest weekdays between approximately 2 p.m. and 7 p.m., or for shorter periods between 2 p.m. and 7 p.m., depending on actual need (but never on weekends or holidays). Randomized programming is used to vary the starting time for cycling across our service territory so the actual start time for each device varies between 2 p.m. and 2:30 p.m. if cycling begins at 2 p.m. The corresponding end time is between 7 p.m. and 7:30 p.m. if cycling ends at 7 p.m. The same pattern follows if cycling occurs for shorter periods.

As a SummerSaver participant, you will receive a $40 end-of-season incentive the first year and a $30 incentive in following years, if you participate the entire cycling season. If participation ends during the four-month period, MidAmerican Energy will prorate your incentive accordingly.

Frequently Asked Questions About the SummerSaver Program
  1. Will I be charged for joining the SummerSaver program?
    • No. The cycling device is mounted on your house and connected to your air conditioner at no cost to you. An outside disconnect switch is required. This also will be installed at no charge.
  2. What do SummerSaver members have to say about the program?
    • Most participants say they do not notice when cycling occurs. Your home's insulation level, directional orientation and shade tree coverage are factors that influence cycling's affect on in-home temperatures. Some homes may experience an in-home temperature increase of 3 to 5 degrees during cycling.
  3. How do I receive my incentive for participating in the SummerSaver program?
    • Your end-of-season incentive will be credited to your October or November energy bill. One incentive credit is available per household, regardless of the number of air conditioners cycled.
MidAmerican Energy continues to expand the geographic reach of the SummerSaver program.

Geographic and equipment availability, minimum summer usage and other restrictions may apply.
