Program Update:

FirstEnergy’s Ohio utilities are committed to making safety our top priority.

Throughout the evolving coronavirus health emergency, FirstEnergy’s Ohio electric companies are committed to closely monitoring developments related to the coronavirus and taking appropriate precautions to protect the health and safety of our employees, contractors and customers.

To ensure that safety, effective immediately, FirstEnergy Ohio electric companies are temporarily suspending all Commercial & Industrial (C&I) Energy Efficiency programs until further notice. Please check back for updates.

This will not impact FirstEnergy’s Ohio C&I customers with pre-approved applications. Customers with pre-approved C&I Energy Efficiency applications may check the status of those applications by emailing a program representative at

FirstEnergy’s Mercantile Customer Program continues to accept applications for projects that are already completed.

Eligible customers wishing to participate in FirstEnergy’s Mercantile Customer Program, or those who have questions regarding the program, may visit the program website by clicking here.

Custom Buildings Incentive Program

The Custom Buildings Incentive Program is offered to commercial, industrial, governmental and institutional customers of Ohio Edison, The Illuminating Company and Toledo Edison (FirstEnergy’s Ohio utilities) for retrofits and new construction projects that include technologies or customer-specific energy efficiency projects that do not meet the eligibility criteria for other business programs.

Possible custom building projects include:

Custom projects include building shell and systems improvements that reduce energy consumption and demand by improving building energy performance. To qualify for incentives, projects must show minimum savings estimates.

  • Replacement of existing windows with high performance glazing
  • Addition of insulation in exterior walls and/or roof that exceeds building code requirements
  • Replacement of existing roof with reflective coating.
  • LEED-certified building, renovation or addition
  • A new building automation control system
  • Smart thermostats


Effective Dates

To qualify for incentives through the Custom Buildings program, equipment must be new and installed after January 1, 2017.

Pre‐Approval Requirements

All custom buildings applications received by the program will require pre-approval before the purchase and installation of materials.


Incentives available from the Custom Buildings Incentive Program are shown below, and are limited to the total project cost. Incentives for smart thermostats are limited to 75 percent of the equipment cost.

New Construction Eligibility Requirements

Eligible new construction and major renovation projects must achieve electrical energy savings exceeding IECC 2009 or ASHRAE 90.1-2007.

Custom Building Performance Incentive

An incentive of $0.05/kWh saved is offered for projects under the Custom Buildings Incentive program. All Custom Building Incentives are limited to 50 percent of the total project cost. Projects must also achieve a minimum savings of 20,000 kWh/year.

Custom Incentives

Measure Equipment & Eligibility Requirements Incentive
Building Automation Controls Eligible projects must include the installation of new energy management system that controls lighting, HVAC and other systems. $0.05/kWh
Smart Thermostats Eligible thermostats must be able to control at least three (3) of the following parameters: Fan delays, free cooling, occupancy sensing, heat pump resistance element lockout, humidity control, compressor optimization, or behavioral “coaching”. Thermostats must control electric heating and/or cooling systems. $0.05/kWh, limited to 75 percent of the thermostat cost.

Annual kWh savings are determined by one of three methods:

  • Performance-based – demonstrated by an hourly energy simulation model. For LEED-certified projects, and other projects which have a detailed energy model, input and output reports from the software program.
  • Deemed – demonstrated by submitting program-approved calculators
  • Measured – demonstrated by site data collection. Direct measurement may take place before or after retrofit, or at both times. In some cases, direct measurement may be combined with engineering calculations to determine electrical energy savings.

How do I apply?

Step 1 – The participant should complete and submit a Custom Buildings Incentive application online and upload required documents through the application portal. The following documents are required for a pre-approval (if the project is already complete, applicants should also submit the required documentation listed in Step 3):

  • Completed and signed W-9 tax form for the incentive payee. The W-9 form must be current and dated within the last 24 months.
  • Scope of work with a summary of the existing and proposed systems
  • Manufacturers’ specification (cut) sheets for each proposed item to verify that the equipment is eligible. Please circle or highlight the relevant information on the specification (cut) sheets.
  • Detailed energy savings analysis/calculations.
  • Copy of utility bill to confirm account number and service address. If desired, the participant may obscure all cost and rate related information.

Step 2 – The Program Administrator will notify the applicant via email when the review is complete and funds have been reserved. The applicant will have 90 days from the date of the pre-approval letter to complete the project.

Step 3 – Once the project is complete, participants should review their application for any changes and submit the following documents to the Program Administrator for review:

  • Revised energy savings analysis/calculations (if changes were made during construction).
  • Detailed, itemized invoices or proofs of purchase for the equipment installed.
  • Completed letter of attestation.
  • If applicable, customers who wish to issue all or a portion of their incentive to a 3rd party should complete a Dual Incentive Payment form.

Supporting technical documentation will be reviewed by Program Administrator and an onsite inspection to verify the installation may be conducted. Upon receipt and verification of all required documentation, the incentive check will be processed and mailed to the applicant or to an authorized representative, if requested on the application.
