Peak shaving and load shifting explained | EVBox
Difference between load shifting and peak shaving. With load shifting you shift some of the load to a more optimal time where electricity is cheaper and costs are lower, but the amount of total energy you use in a day is not affected. With peak shaving, you either take out or add a source of local energy storage to reduce the load on the …
