The price of electricity doesn’t just depend on the season; it also depends on the time of day. Electricity is more expensive from 4 p.m. to 9 p.m. each day. During these “peak hours,” electricity demand can increase as people use large appliances like ovens and stoves to cook dinner; take hot showers or baths, requiring water heaters; or turn on lights as the sun goes down. The sun setting also means that solar panels are producing less energy.
Electricity is least expensive between 10 a.m. and 2 p.m., when the sun is shining and solar panels are producing a surplus of energy, or between midnight and 6 a.m. when demand is low. Shifting major energy use to these “super off-peak hours” can help you save on your energy bill in any season.
