All PeakRewardsSM Air Conditioning program participants have a professionally-installed programmable thermostat or outdoor switch at their home. These devices are what receive the signal to start cycling your air conditioning on and off when energy demand has hit a peak. To ensure your PeakRewards programmable thermostat or outdoor switch is connected and you receive your summer bill credits, please make sure the serial number of your installed device matches BGE’s records.
