Businesses can earn cash-back incentives per project and enjoy long-term energy savings for years to come.

⚠️ In compliance with Ohio House Bill 6, DP&L's mandated energy efficiency programs will end by December 31, 2020. Learn More › 


Custom Rebate applications must be submitted on or before September 30, 2020. Final documentation for an application must be submitted by November 30, 2020. DP&L will continue to pay rebates for existing applications as well as for new applications until funding is depleted or until December 31, whichever comes first. 


DP&L offers Custom Incentives designed for energy efficiency projects and technologies not included under the our Rapid Rebate Program. DP&L Business and Government Customers are eligible for Custom Rebates.

Who Qualifies

All custom rebate applications must be submitted in advance so DP&L can verify the energy baseline before existing equipment is removed. Custom projects that are not pre-approved will be ineligible for a rebate.

To be eligible for a Custom Rebate, your project must:

  • Be any of the following project types:
    • An energy efficiency measure added to an existing system.
    • Early retirement of equipment and replacement with more efficient equipment.
    • Replacement of failed equipment or equipment at the end of its useful life with more efficient equipment.
  • Use electricity as the fuel source and be installed in the DP&L service area.
  • Be comprised of new, unused equipment purchased from a manufacturer, distributor or contractor.
  • Exceed minimum federal- and state-mandated efficiency standards.
  • Have a maximum payback based on electricity cost savings under 7 years and demonstrate permanency or sustainability of savings over the payback period or a 5 year period, whichever is longer.  See Custom Rebate Amounts to calculate your payback.
  • Not circumvent any requirements of the Rapid Rebate program.
  • Combined Heat & Power projects have a separate application process.
  • Be comprised of equipment operating regularly from 3 p.m. to 6 p.m. EST, Monday through Friday, during the months of June through August.

Projects not eligible for Custom Rebates include:

  • Projects for which equipment has already been purchased.
  • Equipment that is part of a new construction project. Learn More ›.
  • Measures installed with funding from another DP&L incentive program.
  • On-site electricity generation or renewable projects.
  • Fuel switching technology, such as electric to gas or gas to electric.
  • Projects where the energy savings result from reduced production or equipment retirement.
  • Changes in operations/maintenance practices or control modifications not involving capital costs.
  • Projects that increase the customer's peak demand.

How it Works

Before you get started, you will need the following information:

  1. Your DP&L account number
  2. A full description of the energy-efficient measures you are planning to install, the cost, life expectancy and operating hours
  3. For each measure, the baseline and new kWh and kW

Please review the eligibility requirements above before completing the application. When applying for a rebate, please follow the process below:

  1. Complete the online application. Please include the following documentation:
    • A description of the affected facility (e.g. building type, facility size, major activities performed).
    • A detailed cost estimate reflecting the costs of purchasing and installing the energy-savings measure (including all materials, labor and equipment discounts). Do not include or factor into your calculations project design costs, energy audit costs, equipment disposal costs, costs incurred from equipment downtime, warranty costs and any other costs not related to the equipment purchase or the installation of the equipment. Rebates will be based on the final cost of the project, less outside funding received, if any. Rebates will be limited to the lesser of 100% of the incremental or 50% of the project cost not including taxes, warranty fees, or maintenance fees.
    • Supporting documentation showing any diagrams, schematics, or other design documents of the before and after state of the system(s). Supporting documentation may be mailed, faxed, emailed or uploaded.
    • A full description of how the energy and demand savings were calculated. Please include formulas and any assumptions that were made. Use rated performance factors from ARI, ANSI, ASTM, ASHRAE or other recognized organizations when possible. It is up to you to present a convincing case for how energy savings should be estimated.
  2. DP&L reviews the application and verifies the information provided. We reserve the right to conduct an audit of your existing equipment and/or the facility in order to calculate energy usage baseline data.
  3. DP&L approves or denies the application.
  4. You provide us with proof of purchase or intent to purchase within 60 days of application submission. This may come in the form of an invoice, purchase order or other supporting document.
  5. You complete your project installation and decommission the old equipment within 120 days of application submission and notify us. You must provide a final, itemized invoice reflecting the true costs of purchasing and installing the energy-savings measure (including all materials, labor, and equipment discounts) as well as equipment serial numbers. If the installation does not occur within 120 days, you must request an extension. Extension approvals will be granted on a case-by-case basis.
  6. DP&L reserves the right to inspect the system(s) prior to releasing any funds.
