If you’re thinking about installing renewable energy at your home, like solar panels on your roof or a wind turbine on your property, please review information on eligibility, installation considerations, and application instructions for renewable energy at your home or business here. The application process is in place to ensure your system meets safety and reliability standards to keep your family, our crews, and all DP&L customers safe.

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?

If you produce your own energy (also known as distributed generation), there may be times when you produce more energy than you need. The energy that you do not use goes back onto the grid to be used by others. The DP&L net meter measures not only how much energy we deliver to your home, but also how much energy you put back on the grid.

How is my bill calculated?

Example: Typical residential monthly energy usage

Total Energy Delivered 1,000 kWh
Excess Energy -230 kWh

Step 1: Your bill is initially calculated based on the TOTAL ENERGY DELIVERED: $112.42.

Step 2: DP&L will recalculate your bill based on the NET USAGE: $89.14.

Step 3: DP&L will issue you a CREDIT for the difference between the two bills. 

  • If you have NOT elected an alternate generation provider and you remain on DP&L's standard service offer (SSO) rate, the credit will include the generation, or supply charges: $23.82
  • If you have elected an alternate generation provider, the credit will not include supply charges: $11.00
  • Credit for any generation charges are the responsibility of the generation provider.

Supply Charge $55.62 $43.34 $12.28 $ -
TOTAL BILL $112.42 $89.14 $23.28 $11.00

Please note that any credit from DP&L will NOT reflect supply charges from an alternate generation provider (shaded charges above). Customers of an alternate generation provider should contact their supplier to receive credit for supply charges. DP&L will provide net usage information to the 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.
