Retrofit FAQ incentive and eligibility update
The Retrofit FAQ now shows a lower small/medium solar PV incentive, tighter eligible installation types, and updated upload instructions for solar DER applicants.
The Frequently asked questions page for the Retrofit Program now shows the small/medium solar PV incentive at $770/kW-AC instead of $860/kW-AC. It also removes ground-mounted installations from eligibility, leaving rooftops and parking canopies as the remaining eligible installation types. Application guidance was also updated for solar DER applicants: they are now directed to upload the latest worksheet instead of a specific Version 2.0 form effective May 30, 2025. The EMIS guidance also changed its cited certification reference and supporting-document language.

- For Solar PV applications, review the Solar Photovoltaic Distributed Energy Resource worksheet and complete and upload the latest Solar DER worksheet to your application.
Processing and Agreement
- Once an application is submitted, it is assigned to a technical reviewer and the pre-approval process takes about two to three weeks to complete.
- The reviewer may request further documentary evidence, and mandatory QA/QC applies to projects that exceed $20,000 in incentive value.
- Some smaller projects may be selected at random for QA/QC during the pre-approval and/or post-approval process.
- After the incentive invoice has been accepted by the reviewer and the application has been approved for payment, payment is typically received within eight to twelve weeks.
- The participant must upload the incentive invoice to the Retrofit portal rather than sending it by mail or email.
Additional information
- Most lighting measures previously available as part of the Retrofit Program are now offered through the Save on Energy Instant Discounts Program.
- The Retrofit Program releases semi-annual updates each spring and fall.
- The program is offered, administered and centrally delivered by the Independent Electricity System Operator (IESO) and its service provider(s).
