Demand Conservation Program Facts
Demand Conservation is a program that allows us to put technology to work to save energy during peak times. We connect a small device to your central air conditioner, water heater or pool pump. When cycling is necessary (on summer weekdays between late afternoon and early evening), we send a signal to your air conditioner or heat pump to cycle off for a few minutes each half hour. Water heater and pool pump cycling occurs on a different schedule.
  • Typically, air conditioner and heat pump cycling occurs no more than 20 days a year — but never on weekends or holidays — between the hours of 2 p.m. and 6 p.m.


  • Most people are not even aware when their air conditioner is being cycled.
