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 even ...
