Energy Demand Management involves regulating the rate of energy use so energy is used in a more efficient way. Many times a higher quantity of energy is used at a specific time during the day. This is referred to as a “Peak” in energy use. If you were to graph your energy use there would be peaks and valleys throughout the day (shown in the figures to the right).
By using an Energy Sentry demand management system, you are able to level off the peaks and fill in the valleys, thus using your energy more efficiently. Energy Sentry acts in a similar manner to the cruise control on your vehicle. You have a set speed (rate of usage) of energy you want to use, and the Energy Sentry controls certain loads to keep the average rate of use below your set limit. An example of loads that would be controlled might be your heating or air conditioning units.
Figure 1 shows that unregulated energy use has very high peaks and low valleys.
