Utility rates for peak electric demand are rising. Knowing when and how often peaks occur is the first step to cutting those costs. Central to that task is the creation of a load distribution curve using software such as Microsoft® Excel™.
Where high peak demand charges (e.g., above $10 per kW per month) are in effect, it may make economic sense to look for ways to trim those peaks. Determining the duration of such high loads helps quantify how much (and how often) peak shaving must be pursued to achieve consistent savings.
