FIT Connection Process




Step 1 –  Independent Electricity System Operator (IESO) approval

To obtain contract approval from the IESO, the applicants must ensure that they select a qualified consultant/contractor to install their FIT project and confirm the proposed capacity. The IESO provides a detailed instruction process, along with the appropriate applications to get the project started on its website.

The applicant will complete and submit a Pre-FIT Consultation Application Form to Toronto Hydro’s Generation Planning team at After reviewing the application, Toronto Hydro will provide the applicant with a Pre-FIT consultation document containing connection details about the project. The applicant will use this document to apply to the IESO for the proposed project and, if approved, receive a conditional contract offer.

Once the application has been reviewed and accepted by the IESO, you will be provided with a
7-digit FIT reference number that is unique to your project.  This number must be referred to in all communications with Toronto Hydro regarding your project.

Step 2 – Request to connect with Toronto Hydro

Once a conditional contract offer and FIT reference number is received from the IESO, the applicant will request to connect with Toronto Hydro.  The applicant is asked to read and understand the FIT Connection Application with Submission Guidelines Form before completing any forms. If you have any questions or concerns, please email or call 416-542-3099.

For FIT projects over 10kW, a Connection Impact Assessment (CIA) must be performed by Toronto Hydro. A CIA is a more detailed assessment of the proposed project’s impact on the Toronto Hydro electricity grid.

The applicant is asked to submit the completed Embedded Generation Connection Application Form and all required documents listed in the FIT Connection Application Guidelines to Toronto Hydro’s Generation Planning team at to begin the process.

Step 3 – Toronto Hydro site inspection

Toronto Hydro will schedule a site inspection prior to the installation of your project. The inspection will document pertinent information about the connection process.

Step 4 – CIA Completion and OPA Notice to Proceed

Once the CIA is completed by Toronto Hydro, the applicant will receive a copy for submission to the OPA for Notice to Proceed (NTP). A FIT project must receive NTP approval from the IESO in order to connect to the Toronto Hydro electricity grid.

Step 5 – Connection Agreement and Process to Install ­

Upon receiving NTP approval, Toronto Hydro will provide the applicant with the connection costs associated with connection to the Toronto Hydro grid. Providing that all the requirements can be met to connect the applicant’s project to the electricity grid, a Connection agreement will then be negotiated between Toronto Hydro and the applicant. Once all of these conditions are met, the applicant will then be able to install the FIT project.

Step 6 – Electrical Safety Authority (ESA) inspection

After project installation, the applicant will need to schedule and complete a safety inspection with the Electrical Safety Authority (ESA). A scanned copy of the ESA notice of inspection shall be emailed to Toronto Hydro’s Generation Planning team at as soon as the final ESA inspection is completed. Please specify in the email subject line: ESA Notice of inspection, project address and FIT ID number.

Step 7 – Finalize your connection

Toronto Hydro will install a separate meter assigned to the project for settlement and data purposes. Once the project has received and reached the Commercial Operation Date (COD) from the IESO, applicant will begin to receive payments for its electricity production according to the metering and settlement payment requirements set out in the contract.
