READ MOREWhen 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 even

Adding a cold water storage tank can achieve two goals: 1- peak load shifting and 2- peak load shaving. In this study, first, the volume of the storage tank was calculated by energy analysis for the day with the maximum cooling needs.
READ MORELoad shifting (or peak shaving) however, deals with the questions of when energy is used, rather than how much. Without load shifting, non-fixed or optional power use (for instance your dishwasher, pool pump, heating and cooling) generally occurs during peak periods in the morning and evening as shown in the diagram below.
