Please complete the form fully with the best available information to ensure a detailed review of the energy-savings opportunity of the measure and to support any subsequent determination of an appropriate prescriptive incentive amount should the measure be accepted to be added to the program. Please submit completed forms to retrofit@ieso.ca.
Completed forms that were submitted by July 29, 2022, will be reviewed and considered for inclusion in the program update planned for Spring 2023. Forms submitted after that date will be considered for a future program update.
Please refer to the chart below for submission dates and the corresponding Retrofit program update.

The evaluation of the submissions involves an in-depth, multi-stage review and approval process to ensure a measure addresses market needs and meets program requirements, including cost-effectiveness, and energy-efficiency policy objectives. As this process is highly detailed, the review can take several months to complete.
The IESO will be posting information on this webpage the first week of each month to provide updates on the status of the evaluation for measures that have been submitted for consideration.
The IESO would like to thank you for your submissions. Each measure submitted for consideration to the Save on Energy Retrofit program is reviewed and screened for possible inclusion in the program. Measures are reviewed for expected energy savings and peak demand reduction, availability, market demand and suitability as a prescriptive measure.
The decisions indicated on the measures below are considered final and will not be reconsidered for the program unless new or updated information is provided.
Please note: the charts below include measures submitted between January 2021 and August 2022. Measures submitted after these dates will be included on this page once all screenings are complete. This page will be updated the first week of each month.
Reminder: The custom stream is returning to the Retrofit program in Spring 2023. See here for more details.
