Have you noticed that your energy bill contains phrases like "off-peak electricity hours" and "peak" usage? Utilities price electricity differently depending on the time of day to reflect the real cost of generating and delivering power.

Off-peak hours are typically overnight and on weekends, when demand on the grid is lowest. Peak hours are during the day, especially in the late afternoon and early evening, when demand is highest.

Shifting flexible loads — like EV charging, laundry, or battery charging — into off-peak hours can meaningfully reduce your monthly bill, especially if your utility offers time-of-use rates.
