Save on Energy Business Program Updates

The Save on Energy suite of programs is changing to provide more cost-effective and streamlined energy-efficiency options to help businesses improve their bottom line. All continuing Save on Energy business programs will be delivered directly by the IESO rather than through your local hydro company.

Here's what you need to know:


The IESO is handling all new Retrofit applications and customer support as of April 1, 2019.

Customers with Retrofit projects that were contracted with their local hydro company can continue to look to their local hydro company for information and support until the project is completed. If you had an application that was not approved before May 1, 2019, you will receive an email notification to transfer your application to the IESO.

For more information, please contact or call the Save on Energy Retrofit Support Line at 1-844-303-5542.

The new Retrofit application portal is now available. Learn how to sign up or login to the portal, as well as access training information and additional resources.

Other Save on Energy programs

Save on Energy will continue to feature the Energy Manager and Energy Performance Programs.


Discontinued programs:

Specialized programs such as Audit Funding, Residential New Construction, High Performance New Construction, Existing Building Commissioning and Monitoring and Targeting are now closed. Applications that are not approved and contracted by your local hydro company before that time will no longer be eligible for funding.

Customers with approved projects that are already underway can continue to look to their local hydro company for information and support until the project is completed. Visit the archive page for documents related to discontinued programs.

A list of the affected local programs are included in the FAQs.
