SALISBURY, Md. - A test conservation period will be called from 9 a.m. to 10 a.m. on Wednesday, May 28 for Delmarva Power's voluntary Energy Wise Rewards program in order to test the equipment prior to the peak summer season.

For those participating customers, Delmarva Power will cycle off participants' air conditioner compressors for short intervals during this time frame. Because the air conditioner fans will continue to run, most customers will not notice a temperature change in their homes. It may take up to a half-hour after the test event ends for air conditioners to resume normal operations.

Energy Wise Rewards is a voluntary program that offers customers a choice of a programmable thermostat or an outdoor switch, which the utility installs at no charge to customers. During summer periods of peak electric demand, Energy Wise Rewards works to reduce electricity usage by cycling off air conditioner compressors for short periods during times of peak electricity use. Customers receive bill reductions in return for allowing Delmarva Power to cycle their air conditioners a few days each year.

Customers can learn more about Energy Wise Rewards by calling 1-866-353-5799 or visiting www.delmarva.com/rewards.
