Washington, D.C. - For customers participating in Pepco's voluntary Energy Wise Rewards program, a test event required by PJM, the Regional Transmission Organization or grid operator for Maryland and the District of Columbia, will be called Tuesday, from 2 to 4 p.m. in order to test the equipment and functionality.

For those participating customers, Pepco will cycle the participants' air conditioner compressors off for short intervals during this time frame. Due to minimal air conditioner use because of anticipated mild weather, customers are not expected to notice any significant change in comfort. 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 the customer. During summer periods of peak electric demand, Energy Wise Rewards works to reduce electricity usage by cycling central air conditioner compressors off for short periods of time during periods of peak electricity use. Customers will receive bill reductions in return for allowing Pepco to cycle their air conditioners a few days each year.

Customers can learn more about Energy Wise Rewards by calling 1-866-353-5798 for Pepco or visiting  www.pepco.com/rewards
