Energy Usage FAQ

How much does OPPD charge for electricity?

OPPD’s Residential Rates can change depending on the time of year. For example: in the summer, OPPD’s rate for all residential customers is $0.0936 for every kWh (kilowatt-hour) of electricity used. For more information, please visit our Residential Rates page on our website.

What affects the cost of electricity?

The cost of electricity is affected in a variety of ways, including:

  • The current rate depending on the time of year. The summer rate is generally a higher rate than the winter rate. Visit our Residential Rates pages for more information.
  • Energy efficiency of your home, appliances, and electronics.
  • Behavior and lifestyle. This can be broken down to the number of people in your home, the number of electronics and appliances and their efficiency, how much those items are used, and the weather.

What’s the difference between a watt and a kilowatt-hour?

A watt is a unit of power whereas a kilowatt-hour is a unit of energy.

One kilowatt [kW] equals 1,000 watts [w].

Kilowatt-hours represent the amount of electric usage over a one-hour period.

Example: 1,000w over a 1 hour period = 1kWh [kilowatt-hour].

How do you calculate kilowatt-hours?
  1. Multiply the wattage of an electric device by the number of hours you use it.
  2. Divide that number by 1,000. That will convert the number from watt-hours to kilowatt-hours.
  3. Multiply the number of kilowatt-hours [kWh] by the cost per kWh to determine the cost of using that device. 

Formula: Watts x hours used ÷ 1,000 x cost per kWh = cost of electricity used

Example: Picture a home using a 2,000-watt window air conditioner, running for eight hours, and the current summer rate is $0.0936 per kWh.
     ~ 2,000 x 8 ÷ 1,000 x $0.0936 = $1.50
     ~ The cost to run the window AC for eight hours is $1.50
