When You Use Energy Matters

Time-of-Use is how electricity pricing works for most customers. Understanding TOU and using electricity when it costs the least can help you lower your energy bill.

Costs More

4 p.m. — 9 p.m.

Electricity is more expensive in the evening, between 4 p.m. and 9 p.m. These “peak hours” are when more people are using large appliances like ovens and stoves to cook dinner; taking hot showers or baths that require water heaters; or turning on lights as the sun goes down. The sun setting also means that solar panels are producing less energy.

Costs Less

10 a.m. — 2 p.m.,
Midnight — 6 a.m.

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.
