Creating a Retrofit Application

Getting started? Here's how to create and submit a Retrofit Application.


Recalling an Application

You can quickly recall an Application if you have submitted one with errors. Note that you won't be able to recall an application once the IESO begins its review.


Copying an Application

If you have similar Retrofit projects, you can copy an existing Application to speed up the process.


Submitting an Amended Application

Just in case – here’s how to request a change to your pre-approved Retrofit Application. This function will be unavailable if you have already submitted your Post-Project Submission.


Creating a Post-Project Submission

You'll need to submit a Post-Project Submission once your project is complete so you can receive your incentive. Here's how to create and submit one.


Submitting a Final Invoice

Once your Post-Project Submission is approved by the IESO, the next step is to submit a Final Invoice to receive your incentive.
