Frequently Asked Questions

Home Energy Reports

Q: How is my home comparison calculated?

A: Your home comparison is calculated using information in your home energy profile. To get the best comparison possible, go to and update your home’s information, including the type of heating and cooling, age, square footage, and more.

Q: What are similar homes?

A: Similar homes are a group of about 100 homes that are similar in size to yours, and are located close to your home. These homes represent homes similar to yours, but do not necessarily include the homes on your block or in your immediate neighborhood.

Q: How did you choose the homes used in the similar homes comparisons?

A: To provide valid comparisons, we choose specific homes that are nearby and have characteristics that typically lead to similar energy needs, such as home size and heating source. And importantly, we only include homes that appear to be occupied at the time of the comparison.

Q: What if there are good reasons that my household uses more energy than other similar homes?

A: Our goal is to provide you with a comparison that is valid and meaningful. Currently, our report comparisons include 100 similar, nearby, occupied homes, and our research shows that for almost all residents, this 100-home average is a good indication of typical usage. However, there are some factors for which we don’t account, such as the number of occupants in the home and special loads like hot tubs and swimming pools.

Q: I have certain life or housing circumstances, such as energy-intensive medical equipment, that prevent me from reducing my energy use. So how can these reports help me?

A: It’s understandable that some people may have life or housing circumstances that make it difficult to reduce their home’s energy use. We aim to provide a wide range of ideas that can address the various needs of our customers and their homes. We encourage you to find out which tips are best for you and search for more ideas. In some cases, you may not be able to realize substantial energy savings, but we’ve found that most people can realize at least some energy savings, and we hope we can help you do so.

Q: How can other efficient similar homes manage to use so much less energy than me?

A: Efficient households likely take a variety of steps to reduce their electric use, including using the thermostat to manage heating and cooling costs, turning off lights and electronics when not in use, and always running full loads in the dishwasher, washer, and dryer. The reports provide actionable steps that you can take to help make your home more efficient.

Q: How do you determine the size of my home, and how do I update it?

A: The square footage of your home that we use in the home energy report is based on data that is collected from your county assessor’s office. If the square footage on your report is not correct, you can update your home energy profile on

Q: What is a kilowatt-hour (kWh)?

A: A kilowatt-hour (kWh) is a way to measure electricity use. A 100-watt light bulb uses 1 kWh every 10 hours.

Q: Where can I learn more?

A: Browse our site to find energy-saving products, rebates and tips. and the American Council for an Energy Efficient Economy are good, independent resources for additional information on energy savings.

Q: Can I opt out of this program?

A: We are providing this service as an educational tool to help you understand your home’s energy use and to share ideas on how you might be able to save money. If you would like to be removed from the program for any reason, you can opt out by updating your usage notifications, or by contacting us by email or by phone at 888-218-3919.

Business Bonus Rebate Calculator

Q: How did you determine the estimated annual bill and kWh savings?

A: The calculator bases the savings for both kWh and annual energy costs on average values for three building sizes (small, medium, and large) from past PSO Business Rebate projects. This is an estimate based on the type of measures and building size selected using the calculator. The determination of building size (small, medium and large) is based upon ASHRAE standards. The electric rate assumed is $0.06/kWh.

Q: How do I qualify for a bonus rebate?

A: Customers who complete three or more different types of retrofit upgrades are eligible for up to a 20% bonus rebate. Eligible retrofit upgrades include:

Plug Load Controls
Window Films
Refrigeration, Kitchen Equipment and Appliances
Custom (Chiller, Compressors, Process, Others)
Check out the bonus requirements to get started.

Q: What does “Payback Period” mean?

A: The simple payback period refers to the amount of time it takes to recover the cost of the upgrades. Simply put, the payback period is the length of time it takes for your investment to reach its break-even point. After the payback period, you start getting a return on your investment through energy bill savings. The payback period is calculated in years.

Q: Why is Public Service Company of Oklahoma trying to help me save energy?

A: Investing in energy efficiency programs helps our customers reduce their energy usage. This reduces the need to build new power plants, makes rates more manageable and reduces the environmental impact from carbon emissions, promoting better air and water quality for the communities PSO serves.

Q: How can I determine which upgrades are right for my business?

A: We encourage you to complete an energy audit to determine which energy-saving upgrades are right for your business. When you complete an audit, all aspects of building efficiency are considered, such as building controls, HVAC, lighting, and more. Check out PSO Energy Coaching or view our list of service providers to get started.

Q: Are the rebate and savings amounts listed on the results page guaranteed?

A: The savings included in the business calculator are estimates. Exact savings will depend on your precise building size, the current state of your building, and the energy-saving upgrades you choose to complete.

Q: Why is lighting automatically included in my list of upgrades?

A: LED lighting offers a great return on investment (ROI) with a short payback period commonly under two years. Combining lighting with other energy-saving upgrades to your building can improve the financial viability of making multiple upgrades at once by reducing the total payback period while increasing your annual energy and bill savings.

Lighting can represent up to a third of your total energy bill, so switching to qualifying LEDs can lighten your annual and peak building loads instantly.

Q: How can I get started on a project?

A: Contact us at or 888.776.1366 to get started today.

Q: What went into this calculation?

A: The calculation includes the average cost of the measures, annual energy savings, annual bill savings, total rebate, and payback period.
