Electricity customers with smart devices can automatically shift their energy usage to when electricity is cheaper and clean, and use less energy when the grid is under stress or running polluting power plants.
How Load Shifting Can Transform Your Home Energy Use
Load shifting is adjusting the time you consume energy from the grid. It''s all about timing – using energy when it costs less. Typically, about 75% of solar energy is produced in the sunnier half of the year. During the less sunny months, load shifting allows you to charge your battery at cheaper rates. For instance, charging your battery ...

Load shifting
Load shifting. Load shifting is a dangerous phenomenon in water, air, and ground transportation where cargo shifts in a cargo vehicle. This causes the vehicle to tilt, which causes even more movement of the cargo, and further tilting, thereby creating a positive feedback loop. If not corrected, this will lead to severe tipping or even capsizing.
