READ MORELoad Shifting with Solar + Battery Storage . Load shifting can save you money and help you avoid expensive time of use rates. But it can also be extremely frustrating. On-peak hours are, after all, the most popular time to use electricity. From 4 pm to 7 pm (APS Energy on-peak hours) it''s still hot out and you want your air conditioning

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
