Peak Shifting is a " demand side management " or DSM strategy that is highly cost-effective method of reducing electric utility expenses. When electric utility commercial or industrial customers use electricity can make a big difference on their monthly electric bills. By shifting the time of day that electric power is used, a commercial or
The load shifting rate (LSR) was employed to characterize the peak shifting potential of the heating system combined with the thermal energy storage apparatus [28]. The LSR was defined as the ratio of the power consumed during the off-peak periods to the total power consumption, as calculated in the following Eq.

Peak shaving and load shifting also help make a facility''s day to day operations more sustainable. These demand management tactics help local grids integrate intermittent renewable energy. This translates to lower reliance on carbon-based power plants for electricity, lowering both your community''s and business''s carbon footprints.
When peak-load shifting is applied to reduce energy costs, it is often referred to as "peak shaving." Peak shaving describes when a facility uses a local energy storage system to compensate for the facility''s large energy consumption during peak hours of the day. Most facilities do not operate 24 hr/day. In fact, most facilities do not
