A: ComEd is now offering incentives for the installation of GHP systems at existing non-residential buildings.

Q: What is the incentive level?

A: The ComEd Commercial Geothermal Heat Pump Incentive provides $1,000 per ton of installed capacity, up to 50% of the project cost.

Q: Who is eligible for this incentive?

A: The ComEd Commercial Geothermal Heat Pump Incentive is available to ComEd delivery service, non-residential customers with an existing ComEd account number. New construction projects are not eligible for this incentive.

Q: What types of geothermal heat pumps are eligible?

A: Projects must involve the installation and operation of qualified geothermal heat pumps as the primary heating and cooling system on an existing non-residential building. The geothermal heat pump must be installed and operational between May 1, 2018 and June 30, 2019. There is a 50-ton ceiling on the size of the systems allowed.

The system must be replacing one or more of the following system configurations in an existing building:

  • Electric resistance heating with or without cooling
  • Non-electric heating (e.g. natural gas, propane or oil system) with or without cooling
  • Heat pump
  • Existing geothermal heat pump, retrofitting both the indoor unit and ground loop system

The geothermal heat pump system installed must be AHRI certified and meet the following minimum efficiency requirements:

System Type Cooling EER Heating COP
Water to Air: Water Loop NA ≥ 4.3
Water to Air: Ground Water ≥ 18 ≥ 3.7
Brine to Air: Ground Loop ≥ 14.1 ≥ 3.2
Water to Water: Water Loop ≥ 10.6 ≥ 3.7
Water to Water: Ground Water ≥ 16.3 ≥ 3.1
Brine to Water: Ground Loop ≥ 12.1 ≥ 2.5

Q: Are there additional installation requirements?

A: The installer contractor must have the following credentials:

  • ComEd Energy Efficiency Business Trade Ally;
  • Illinois Commerce Commission (ICC) Energy Efficiency Installer Certification; and,
  • Geothermal Alliance of Illinois (GAOI) design and install accreditation.

Q: Does my new construction building with a geothermal heat pump system qualify?

A: No. New construction buildings are currently incentivized under the ComEd C&I New Construction Program and will not be considered under the ComEd Commercial Geothermal Heat Pump Incentive.

Q: How do I apply for this incentive?

Download the Pre-Approval Application to verify project eligibility. Follow the instructions on this document and submit it to ComEd.

Q: What information is required in the Pre-Approval Application?

A: Pre-Approval Applications will require load calculations, requirement descriptions, Air Conditioning, Heating, & Refrigeration Institute (AHRI) equipment certificates, and incentive calculations. If additional information is needed, ComEd will work with contractors and customers to obtain the necessary information.

After reviewing submittal information, ComEd will notify you if the project has received Pre-Approval, at which point you can move forward with project installation.

Q: When do I submit a Final Rebate Application?

A: After a project is completed, submit the Final Rebate Application with both customer and contractor signatures. ComEd will review the application and supporting documentation before issuing the incentive payment. ComEd will conduct an on-site review, though this review may occur after an incentive is paid.
