Feed-in Tariff (FIT) Frequently Asked Questions

How should the application form be submitted to the IESO, e.g. e-mail, fax?

An e-mail is preferable for documents and files.  Please ensure any signature pages are scanned and e-mailed to the IESO in PDF format.

When is payment required for a connection assessment application for a FIT project?

Payment for FIT projects can be submitted at any time; before the application is submitted, with the application or after the application has been submitted, however payment is required to deem the application complete.  For payments submitted before the application, please include the proof of payment with the application. The payment/deposit amounts for the IESO include GST (no need to add GST).  However, for payments to Hydro One, please add GST.

If the FIT applicant has previously paid a deposit to the IESO for a similar project, does the full deposit have to be submitted when applying with the same project as a FIT project?

Yes, a full deposit is required with each application for a FIT project. Any existing applications must be rescinded before a project can be submitted to the OPA for the FIT program and the deposit to the IESO cannot be used for new application.  To rescind an existing impact assessment, please submit a Notification of Withdrawal (form 1073).  

Does the combined application (System Impact Assessment/Customer Impact Assessment) have to be sent to both the IESO and the transmitter within the OPA application window?

No, the combined application must be sent to the IESO during the application window.  The IESO will forward the application to, and work with, the applicable transmitter.

Can projects with different connection points from the same FIT applicant be combined in a single application?

No, separate applications must be submitted since there may be different outcomes of the connection assessments for the different connection points, e.g. different transmission modifications.

Can projects with the same connection point from the same FIT applicant be combined in a single application?

Yes, a single application can be submitted as long as the project is from the same applicant at the same connection point using the same technology.

What if some of the technical data for the FIT project is not available at the time of the application submission window?

The application should be submitted within the application window even if data is missing or incomplete. The application should contain the best information available at the time of the application submission window.  In order to reduce the number of study iterations resulting from data changes during the connection assessments (which would escalate the cost associated with the study), we encourage the applicants to finalize the design of their facilities before the application is deemed complete.

Is the information on excitation system model, governor and prime system mover model and facility model required at the time the application is submitted? What if this information is not made available by the manufacturer in time for the application submission priority window or at all?

The connection assessment application should contain the best information available at the time of the application window.   The IESO and the transmitter will review this information and if the application is incomplete we will advise the applicant.  We will begin working on the assessment when all the application information is given to us.

When the IESO requests PTI models for System Impact Assessment studies, which version of PTI is required?

Model parameters must be submitted to the IESO in PSS/E, version 30.2.

What if some of project dates (e.g. backfeed power dates, construction dates, etc.) are not firm at the time of the application submission window?

Your best estimates are acceptable.  Please update the IESO as soon as possible if these dates change.

Will a change to the application data cause a change in the OPA priority?

No, from an IESO viewpoint no matter when we start/pause/reset the service guarantee time clock due to incomplete/small changes to/large changes to data, a FIT applicant’s OPA priority will not be changed.

What degree of change will necessitate a stop of the service guarantee clock?

After the application is deemed to be complete and the service guarantee clock is started, depending on the size of the change there are three main options:

i) A major change (e.g. change of connection point, turbine technology, collector station layout and changes to the collector system so large that they significantly change the parameters of the equivalent machines at the collector bus) will require that the 150 day service guarantee clock is reset to zero and the SIA study is redone.
ii) Minor changes (e.g. small changes to the collector system, etc.) that require only a small portion of the analyses to be repeated and minor revisions to the SIA should not require a stop to the service guarantee clock unless there is not enough time remaining to complete the SIA with the minor changes. Alternatively, the IESO may close the SIA as it is and later issue an addendum to the original SIA.

There is also the possibility of requesting that the service guarantee clock be paused in order to allow the applicant more time to finalize the changes to technical details.  This is an avenue only the applicant can take by requesting the IESO to pause the clock.

It is critically important to let the IESO know as soon as you become aware of data changes.
