TOU plan prices

Energy is priced per kilowatt-hour (kWh) and your monthly energy charge is based on the total amount of energy used during your billing cycle. The amount used in your home is constantly monitored and recorded by the meter. For example, if you use a 1 kW appliance for three hours, you use 3 kWh of electricity.

Why are energy prices higher in the summer?

The kWh or unit cost of energy is different in winter and summer regardless of your price plan. The price you pay rises and falls with the demand for electricity. During the coolest months, customer usage, generation costs and the price you pay are lowest. During the hottest months, customer usage skyrockets and generation costs to meet peak demand are highest.
