If you install solar panels or another renewable energy system, consider how your bill may change.
If you’re thinking about installing renewable energy at your home, like solar panels on your roof or a wind turbine on your property, there are a number of decisions to consider. First, please review information on eligibility, installation considerations, and application instructions for renewable energy at your home or business here. To keep your family, our crews and all DP&L customers safe, it is important to follow our application process to ensure your system meets safety and reliability standards.
What is net metering?
Net metering is the difference between how much energy DP&L delivers to you and how much energy we receive from you. The difference is measured by a net meter installed by DP&L after your renewable energy system is connected to the grid and your interconnection is approved. The interconnection process is necessary to ensure your system is operating in parallel with DP&L’s delivery system.
NOTE: Unless you have batteries or other energy storage technology, the energy cannot be stored. Excess energy is pushed back onto the DP&L grid.
How does net metering affect my bill?
Your total bill includes delivery and supply charges. DP&L may provide delivery and generation supply (labeled as "Supply Charges" on your bill) to customers, or electric choice allows customers to purchase generation supply service from a competitive retail electric service (CRES) provider at a rate/price not regulated by the Public Utilities Commission of Ohio (PUCO).
If a customer chooses to purchase supply from a CRES provider, the provider places the supply charges either on the DP&L bill or on a separate bill to the customer.
How is my electric bill calculated?
The example below explains a typical bill for a residential customer with a net metering system.
- Your bill is initially calculated based on the total energy delivered by DP&L: $143.99.
- DP&L will recalculate your bill based on the Net Usage: total energy delivered by DP&L minus energy received from your system.
You will receive a credit for the difference between the two bills:
- If DP&L is the generation provider, the credit in the example below would be $29.56.
- If you have signed up with a CRES provider, the credit from DP&L would be $12.16.

NOTE: Any credit from DP&L will not reflect bypassable components (shaded charges above) from a CRES provider. Customers of CRES providers should contact their provider to receive credit for supply charges. DP&L will provide net usage information to the CRES provider upon request.
Will installing a renewable energy system lower my electric bill?
The amount of energy you use is not likely to change based on the installation of a renewable energy system. Depending on your energy needs, your DP&L bill could decrease if less energy is delivered by DP&L. If you purchase electricity from a CRES provider, DP&L can only credit the portion of your bill allocated to delivery charges. Contact your provider to request a credit for the supply charges.
How much does a net meter cost to install?
DP&L does not install renewable energy at your home. Customers are responsible for the cost to install solar panels or other renewable energy systems. DP&L charges a $95 one-time fee to exchange the existing utility meter with a net meter. Additionally, there is an application fee to review your application to ensure your interconnection meets DP&L's safety and reliability standards. The average total cost for DP&L-related charges for a residential customer is $130.
