Off-Peak Electricity Hours: What time of Day is Cheapest?
When demand is lower, the cheapest electricity can be found during "off-peak" hours. An example of one time-of-use rate schedule with Pacific Gas & Electric in California. Energy is usually cheapest at night, regardless of region or time of year. But the exact timing depends primarily on your location and the off-peak periods utilities operate.
