Load shifting
Charging the battery when energy is cheap and discharging it when energy is expensive - shifting *when* the site draws grid power, not how much.
Load shifting reduces the on-site electricity bill by charging a battery during low-price hours (typically overnight or during shoulder-tariff periods) and discharging it during high-price hours.
Unlike peak shaving - which targets the demand-charge component of the bill - load shifting targets the energy volume charge, and the arbitrage between low and high tariff windows.
The two techniques are usually combined: a well-configured control layer runs peak shaving and load shifting simultaneously, subject to the site's backup floor.
