With peak shaving, a consumer reduces power consumption (" load shedding ") quickly and for a short period of time to avoid a spike in consumption. This is either possible by temporarily scaling down production, activating an on-site power generation system, or relying on a battery. In contrast, load shifting refers to a short-term reduction in

PEAK SHAVING. Load shifting, or demand response, optimizes electricity use and can reduce energy costs. While similar to peak shaving, with its goal to relieve stress on the electric grid within peak demand periods, the way load shifting achieves this is different.
