How the program works

Project scoping stage

Contact your Energy Services Advisor (ESA) early in the project planning stage to have your project pre-qualified and maximize the incentives available to you. We’ll estimate natural gas savings based on the project details and provide an incentive quote. If you haven’t already worked with an ESA, you’ll be provided with one for support every step of the way, at no additional cost.

Two

Purchase order stage

Contact your ESA and provide a copy of the purchase order. Work with your ESA to submit required technical inputs with an estimated date of installation.

Three

Project Installation

After the energy efficiency upgrade is installed and in service, your ESA will confirm final project details through a site inspection and/or by requesting a copy of the project invoice.

4

Incentive payment

Submit all required paperwork and receive your incentive cheque in 4–6 weeks. An independent evaluator may reach out to verify project details and your experience with the program.

Are you an affordable housing provider?

The Affordable Housing Multi-Residential program provides incentives for eligible energy-efficient upgrades in social, affordable and market-rate multi-family buildings.

* Institutional customers include universities, colleges, hospitals, military bases and district energy providers.

Terms and Conditions: 
Contact an Enbridge Gas Energy Solutions Advisor to confirm your project’s eligibility. All Commercial Custom Retrofit projects must be pre-approved by Enbridge Gas to qualify for incentives. HST will not be included in incentive payments. Incentives are only made available to customers where Enbridge Gas energy efficiency offer(s) have impacted the customer’s decision to proceed with the improvement(s). Incentive cannot exceed 50 percent of the energy efficiency upgrade costs (‘upgrade costs’ refer to the difference between the equipment and implementation costs of the energy-efficient option and those of the alternate option considered), to a maximum of $100,000 per project (for institutional customers, to a maximum of $500,000 per project).

Commercial controls offer is available to all Enbridge Gas commercial customers. For institutional demand control ventilation (DCV) projects, please contact your Energy Solutions Advisor for eligibility criteria. Incentives are calculated based on natural gas savings ($/m3 rate), up to 50 percent of energy efficiency upgrade costs, to a maximum of $100,000 per project.

Disclaimers:
Any references to energy savings is based on the assumption that the participant is reducing their natural gas consumption through participation in the Commercial Custom Retrofit Program. The savings claim for the featured case study is provided for informational purposes only and is based on estimated natural gas savings of 73,802 at $0.30/m3. These projections are specific to this example, and actual savings may vary for each project.

Any references to Greenhouse Gas Emissions (GHG) reductions are based on the assumption that participation in the Commercial Custom Retrofit Program results in reduced natural gas consumption. Enbridge Gas does not make any claims regarding the specific amount of GHG reductions achieved.
