Connection Availability

You are strongly encouraged to review the Connection Availability Resources, FIT Rules, Standard Definitions and IT Contract, located on the Program Resources page of this website, to determine the connection feasibility and requirements for the program and for your specific project.  You can also review the FAQ document to see answers to some commonly asked questions.

All FIT applications that are complete and eligible will be required to undergo connection availability screening. The IESO will use the following tests in the connection availability screening.

Transmission Availability Test (TAT)
In the TAT, applications will be assessed in sequential order based on the priority ranking of all applications which is established through the application completeness and eligibility review. The TAT considers:

  • All prior OPA and IESO contracts

  • Prior applications that have been processed

  • System capacity allocated to other IESO programs (such as the microFIT Program)

  • Any other generation facilities that are existing, committed or are the subject of a ministerial direction

Distribution Availability Test (DAT)
In DAT, applications will be assessed in sequential order based on the established priority ranking. The DAT considers:

  • All prior OPA and IESO contracts

  • Prior applications that have been processed

  • Any other generation facilities that are existing, committed or are the subject of a ministerial direction.

Projects will need to pass both the TAT and the DAT to receive a FIT Contract offer. The application will be terminated if it fails either of the two tests. The IESO will only offer contracts up to the procurement target of a specific application period. To review the MW allocation for the current procurement target you can visit the Defined Terms for the Current Application Period page of the website.
