The following is the process for connecting a micro generation facility to Horizon Utilities' distribution system under the microFIT program offered by the Independent Electricity System Operator (IESO).

  1. The customer applies for a microFIT contract with the IESO. Click here to visit the microFIT program website.
  2. The customer should confirm if the microFIT location is in an area of non-constraint (may connect) or in an area of constraint (may not connect). An area of constraint means that the Hydro One Transformation Stations do not have capacity to connect generation (Microfit).
  3. The customer submits an application for connection to Horizon Utilities. Click here to download the application form.
  4. Once Horizon Utilities receives the microFIT application and is verified. If the application is accepted, Horizon Utilities will update the IESO website by acknowledging the "Connection Request Date".
  5. Once the microFIT location has been verified as non-constraint or constraint, Horizon Utilities will update the IESO website in acknowledging the "LDC has issued the Offer to Connect" or the “LDC has determined there is no connection capability”
  6. Once Horizon Utilities receives the standard payment fee and the "LDC has issued the Offer to Connect", a site-visit/Service Layout Form (SLF) is scheduled. The customer does not need to be present for the SLF.
  7. A Horizon Utilities representative completes the SLF to confirm the location of the micro generation facility and the generation meter to be installed. The standard payment fee will be confirmed and if applicable, the SLF will also stipulate any extra work (fees) that needs to be completed in order to receive a connection. The Horizon Utilities representative provides a copy of the SLF by fax or email to the customer/contractor.
  8. The customer/contractor installs the micro generation facility and applies to the Electrical Safety Authority (ESA) for an electrical inspection. Click here for the ESA's guidelines for micro generation.
  9. Once ESA provides Horizon Utilities with the electrical inspection "Authorization for Connection", Horizon Utilities, ESA and the customer's electrician will schedule a date and time for a "cut and Hold". The customer/contractor initiates the call.
  10. Horizon Utilities sets up a new customer generation account and installs the new generation meter.
  11. The customer completes and submits the Connection Agreement. Click here to download the Connection Agreement.
  12. Once Horizon Utilities receives the Connection Agreement, Horizon Utilities will update the IESO website in acknowledging the “Connection Completed”
  13. The customer enters into a microFIT contract with the IESO. Once the IESO notifies Horizon Utilities that the microFIT contract has been executed, Horizon Utilities commences settlement of the new generation account at the microFIT contract price.

Frequently Asked Questions

  1. Do I have the option of having my microFIT generation meter connected in series or in parallel with the primary (load) meter?

    No. The microFIT generation meter must be connected in parallel with the primary (load) meter.
  2. Are there areas that are constraint (no capacity to connect microFIT)?

    Yes, there are areas where there is no capacity to connect. We recommend that you send an email (to microfit@horizonutilities.com.​) requesting confirmation.
  3. Are there Drawings for a microFIT connections?

    Yes, click here to access the residential and commercial drawing.
  4. What are the costs associated with connecting my microFIT project to the grid?

    For a standard microFIT project, there is a one-time payment fee of $500 plus HST ($565.00) for a microFIT connection on a residential service and $1000 plus HST ($1130.00) for a microFIT connection on a commercial service. This charge includes the cost of a site visit, the installation of a generation meter, and the disconnection/reconnection of the service. The deposit is collected against the cost of processing the application – regardless of whether or not the project is ultimately connected. Additional payment or work may be incurred if the project is non-standard.

    There is also a one-time charge of $30 for the set up of a microFIT account. This charge will appear in the first microFIT account statement.
  5. What form of payment is acceptable and how can the payment be made?

    The cheque should be made out to "Horizon Utilities Corp." (NOTE: Cash payments are not accepted. Cheques or money orders only.):

    340 Vancsickle Road, St. Catharines
  6. Are there any ongoing account fees for a microFIT account?

    There is a monthly service charge of $5.40 on microFIT generation accounts. This charge covers the cost of maintaining the meter and the account.
  7. I have completed a Microfit installation and received an ESA certificate, how do I initiate a request for connection?

    Call Horizon Utilities Customer Connections Department at (905) 522-6611 x4820.
  8. Does the name on the microFIT generation account have to be the same as the name on the primary (load) account?

    No. The name on the microFIT generation account does not have to be the same as the name on the primary (load) account. This is because the microFIT generation account will be completely separate from the primary (load) account. However, the name on the microFIT generation account must be the same on both the OPA's application form and on Horizon Utilities application form.
  9. How are the two accounts settled?

    The primary (load) account will be settled for the energy (kilowatt-hours) consumed (no change to the present Billing account). The microFIT generation account will be settled for the total energy (kilowatt-hours) generated and the total energy (kilowatt-hours) consumed. The microFIT generation payment will follow the billing cycle of the primary (load) account..
