What do I need to include in my Commercial Rebate application as supporting documentation?

A complete application packet includes:

  • A completed and signed application form.
  • Itemized invoices for equipment and proof of payment.
  • Manufacturer specification sheets that include: manufacturer catalog/model number, size, operation and efficiency levels for each piece of proposed equipment. A/C installations require a copy of the Air-Conditioning, Heating and Refrigeration Institute (AHRI) certificate that includes model numbers for the condenser unit and evaporator coil consistent with proof-of-purchase documents.
  • For custom rebates, the applicant must provide all calculations that document energy savings. For LED lighting projects, customers will be contacted to provide additional information. Saving calculations are to be submitted in their original format, such as Microsoft Excel or the modeling software that is used. Supporting documentation includes the following:
    • Calculations of annual baseline energy use (pre-installation);
    • Calculations of proposed energy use (post-installation);
    • Estimated annual energy savings in kWh/year;
    • Estimated peak demand reductions in kW;
    • Equipment manufacturer specification (cut) sheets for proposed equipment;
    • Documentation to provide assurance that the settings used to calculate the savings will not be changed for Energy Management Systems and Control upgrades; and
    • For LED lighting projects, customer will be contacted to provide additional information.

What is an acceptable proof of payment for a Commercial Rebate?

Acceptable proof of payment includes either a copy of the check or a computer screenshot showing payment information if you have used an automatic payment system.

Am I eligible for this Commercial Rebate program?

Commercial rebates are available to all LG&E and KU commercial electric customers who contribute to Demand Side Management as part of their monthly bills. This program is not available to gas-only customers.

Equipment efficiency requirements are subject to change, as Federal Energy Policy Law changes. Further, rebates are subject to change, based on changes in the marketplace. LG&E and KU will post all changes at lge-ku.com/rebate and also will reflect changes/updates on program materials. Applications deemed eligible prior to the date the rebates changed will be eligible for the rebate amount in effect at the time the application was submitted and processed. Rebates will never exceed the cost of the equipment being installed.

What types of improvements are not eligible for Commercial Rebates?

  • Appliances
  • Motor soft starts
  • Fuel switching
  • Programmable thermostats
  • Any electric generation projects
  • Renewable energy technologies that generate electricity

What happens after I've signed up online or by phone for a Commercial Rebate?

After you sign up, an application will be mailed to your business’s mailing address for your signature. From there you will need to read, complete and sign the rebate application and gather your supporting documentation. For step-by-step instructions, visit our “How it works” page.

What is the Commercial Rebate site verification?

Site verification may be required to process your rebate application. During site verification, a E-Max representative will confirm quantities, make and model numbers of each equipment type listed on the Installation Confirmation form(s).

If your facility is selected for site verification, you will be contacted by E-Max to schedule an on-site visit to your facility. Someone from your facility will need to accompany our business partner during the site verification. Rebates will remain in a pending status until site verification is complete.

How do I determine my energy savings for customized Commercial Rebates?

Custom projects must include improvements that help reduce peak summer electric load greater than one kilowatt, averaged over the June through September billing periods. Applications for customized rebates must be accompanied by all calculations that document the energy savings, in addition to your complete application packet. Please provide all calculations in original format, such as Microsoft Excel® or the modeling software, to allow for easier review.

Can I choose who performs my improvements for qualifying Commercial Rebates?

Customers may select an appropriate vendor of their choosing to supply and/or install the improvements that qualify for commercial rebates. Customers may choose to self-install the equipment.

Do LG&E and KU offer energy audits for commercial customers?

LG&E and KU do not currently offer energy audits for commercial customers. If a customer has an energy audit performed by a service provider, they may qualify for a rebate to help offset part of the cost. Learn more about our rebates for energy audits.
