Commercial Custom Retrofit Program


An Enbridge Gas Energy Solutions Advisor will work with you, free of charge, to identify energy efficiency opportunities that save natural gas and in return save you money. If you implement any of our recommendations, we will cover up to 50% of the project cost.

Through the Commercial Custom Retrofit Program, financial incentives* are rewarded for investing in capital projects that save natural gas. Examples of common projects include upgrading to energy efficient boilers and water heaters, installing make-up air units, or implementing building controls.

A dedicated Enbridge Gas Energy Solutions Advisor (ESA) will work with you every step of the way:

  • Opportunity Identification - Your ESA will conduct a free site walkthrough to identify opportunities that can help you save energy and money.
  • Energy Savings and Incentives Estimates – Based on the information collected at the site walkthrough, your ESA will calculate the estimated gas savings associated with the opportunity identified as well as any Enbridge Gas financial incentives you may qualify for.
  • Installation of Equipment – To get the job done right, your ESA can connect you with:
    • Proven trade professionals
    • Financial incentive of $.20/m3 natural gas saved up to 50% of project cost to a maximum of $100,000 per project.

The more natural gas you save, the higher the incentive rate you qualify for.
