Delmarva Power to Conduct Peak Savings Day Test Sept. 18

SALISBURY, Md. - Delmarva Power asks all of its customers to conserve energy from 2 p.m. to 3 p.m. on Thursday, Sept. 18 as part of a test event required by PJM, the electric grid operator for Maryland and Delaware.

For Delaware residential and small commercial customers, Thursday will be a Peak Savings Day which means customers will be rewarded with bill credits when they voluntarily reduce energy use. Delaware customers will automatically receive a phone call indicating that the savings period will be from 2 p.m. to 3 p.m. on Thursday, Sept. 18.

Delaware residential and small commercial customers who reduce energy use below their specified baseline during the specific hours of the Peak Savings Day can receive a credit of $1.25 off their bill for every kilowatt hour (kWh) of reduced usage through the Peak Energy Savings Credit program.

For Delaware and Maryland customers participating in Delmarva Power's Energy Wise Rewards program, a conservation event will be called from 2 p.m. to 3 p.m. on Thursday, Sept. 18. This means that Delmarva Power will cycle participants' air conditioner compressors off and on for short intervals during this hour. Because the air conditioner fans will continue to run, most customers will not notice a temperature change in their homes, and those who do should experience only a 1- to 3-degree change. It may take up to a half-hour after the test event ends at 3 p.m. for air conditioners to resume normal operations.

Energy Wise Rewards is a voluntary program for customers, offering 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 air conditioner compressors off and on for short periods during times of peak electricity use.

Maryland customers will receive a bill reduction in return for allowing Delmarva Power to cycle their air conditioners a few days each year. The automatic air conditioner energy reduction will contribute to participating Delaware customers' Peak Energy Savings Credit.

Delmarva Power asks all customers to conserve electricity. Customers can take simple conservation steps:

  • Set air-conditioning thermostats at 78 degrees and use an electric fan, which doesn't require as much energy, and the air will seem cooler without sacrificing comfort.
  • Keep window shades, blinds or drapes closed to block the sunlight during the hottest part of the day and to retain cooler air inside your home or business.
  • Limit the use of electrically heated water and turn off non-essential appliances and as many lights as possible.
  • Limit opening refrigerator and freezer doors.
  • Postpone using high-energy appliances like electric stoves, washing machines, dishwashers and dryers until the evening.
