Peak Shaving | What it is & how it works
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 ...
