Load Shifting
Load shifting from low-cost charging to higher-cost periods
Load shifting stores energy during low-tariff periods (off-peak, solar generation) and discharges during high-tariff periods. This energy arbitrage directly reduces electricity costs without changing consumption patterns.

Typical configuration envelope
Load shifting is an energy-driven application, sized around the magnitude and duration of the daily off-peak / on-peak price spread.

Load Shifting – Deployment Case Study
A commercial complex with a 150 kW solar array was exporting 60% of generation due to midday low-demand periods, while paying peak rates in the evening.
A 400 kWh BESS captures midday solar surplus and discharges during the 18:00–21:00 peak tariff window.
- Solar self-consumption increased from 40% to 92%
- Annual electricity cost reduced by R280,000
- Carbon emissions reduced by 45 tonnes / year
Plan your load shifting schedule
Start with the tariff periods, site demand and available charging capacity. Then compare the value of shifting energy with conversion losses and the planned duty cycle. Load shifting needs a feasible recharge window as well as enough stored energy to cover the target period.
Compare BX commercial battery systems or discuss your site requirements. For background, see the U.S. Department of Energy’s energy storage research and resources.
