Comparing Energy Prices

How to compare a supplier’s price to DP&L’s price.

DP&L’s Standard Offer Rate

If you do not want to choose a supplier, you will automatically be enrolled on DP&L’s standard offer rate. This is our default supply rate, which is determined by a competitive auction that reflects market prices for providing generation service.


When comparing electric generation suppliers you need to know the Annual Price-to-Compare and the Average Annual Cost (cents per kilowatt hour or kWh for short) that a supplier must beat (compared to DP&L's standard offer rate) in order for you to save money. In other words, the Annual Price-to-Compare is the amount that you no longer have to pay to DP&L when you choose an alternate electric generation supplier.?

For example: If the annual charges that you avoid paying to DP&L when you choose an alternate generation supplier are $500, the supplier’s annual charges must be less than $500 in order for you to save money on your electric bill.

Residential Customers

  • If you are a residential customer, you will find your Price-to-Compare in the bill message on your monthly DP&L bill.
  • If you are comparing electric generation suppliers on price, paying a lower price in cents per kWh should result in a lower electric bill. However, suppliers may charge other fees and all costs should be considered before choosing a supplier. Be sure to ask a potential supplier about any fees that may affect your overall cost.
  • In order to compare the estimated annual costs you would pay an alternate electric generation supplier, determine your annual usage for the last 12 months (shown on your DP&L bill or Usage History on MyDP&L) and multiply this by the supplier’s price (cents/kWh).

Business Customers

  • If you are a business customer, you can use the Price-to-Compare Calculator available below. The Price-to-Compare also converts this amount into an average rate or cents/kWh amount.
You'll need the following
  • Rate Number
  • Billing Demand (kW)
  • Billed kVar (if applicable)
  • Kilowatt Hour Usage (kWh)
Here's where you can find this information on your bill:


* To get a more accurate Price-to-Compare it is suggested that you input information for the most recent 12 months instead of just one, to take into account seasonal variations.
