Distributed Energy Resources

Alectra Utilities connects Distributed Energy Resources facilities including solar panels, combined heat and power plants, energy storage, and natural gas-fuelled generators to Ontario’s energy distribution system. Our Distributed Energy Resources group assesses and approves the connection to the distribution system.

Small, Mid-sized and Large Embedded Generators (>10kW) Connection Process

The following is the current connection process overview for generators that are greater than 10kW and operate at voltages below 50kV and is subject to change at any time.

  1. Preliminary Consultation
    Customer submits a completed Form A – Preliminary Consultation Application. Alectra Utilities establishes the generator classification and provides the connection details of the proposed project and available capacity.
     
  2. Connection Impact Assessment Application
    Customer submits a completed Form B – Connection Impact Assessment Application.
     
  3. Study Agreement
    After the Form B is reviewed by Alectra Utilities, the Customer submits a signed Study Agreement along with payment for the Connection Impact Assessment.
     
  4. Connection Impact Assessment
    Alectra Utilities performs a Connection Impact Assessment and issues the report to the customer. The Customer is allocated capacity upon completion of the Connection Impact Assessment by Alectra Utilities and Hydro One (if applicable).

    Note: For generators connecting on a Hydro One shared feeder, Hydro One will be required to perform its own Connection Impact Assessment.
     
  5. Connection Cost Agreement
    Alectra Utilities performs a cost estimate and issues a Connection Cost Agreement specifying the scope of work to be performed either by Alectra Utilities or the customer in order to make the generation connection.

    If the Customer decides to proceed with the project, Customer signs the Connection Cost Agreement and makes the required payments.
     
  6. Design and Build
    Alectra Utilities performs the work required to make the connection. The customer completes the construction of the generation facility and applies to the Electrical Safety Authority for an electrical inspection. The customer submits final detailed design documents to Alectra Utilities for review.
     
  7. Commissioning
    Customer completes and submits a Commissioning Verification Report including the Commissioning Verification Form.
     
  8. Connection Agreement
    Customer completes and submits the Connection Agreement prior to energization.
     
  9. Connect, Operate and Maintain
    After the Electrical Safety Authority provides the electrical inspection “Connection Authorization” directly to Alectra Utilities, the generation facility is connected to Alectra Utilities’ distribution system.

    Alectra Utilities will work with the customer to set up the appropriate settlement arrangement based on the project type.

The following is the current connection process overview for generators that are less or equal to 10kW and operate at voltages below 50kV and is subject to change at any time.

  1. Preliminary Consultation
    Customer submits a completed Form A – Preliminary Consultation Application. Alectra Utilities establishes the generator classification and determines if there is capacity available for the proposed generator.
     
  2. Connection Application
    Customer submits a completed Form C – Micro Generation Connection Application
     
  3. Offer to Connect
    Alectra Utilities reviews the application and once it is accepted, an Offer to Connect is issued to the Customer with the requirements and construction costs to connect the generator.

    If the Customer decides to proceed with the project, Customer pays Alectra Utilities the connection fees as per the Offer to Connect.
     
  4. Design and Build
    Customer installs the micro generation facility according to Alectra Utilities’ requirements and applies to the Electrical Safety Authority (for an electrical inspection.
     
  5. Commissioning
    Customer completes and submits the signed Commissioning Verification Form.
     
  6. Connection Agreement
    Customer completes and submits the Connection Agreement prior to energization.
     
  7. Connect, Operate and Maintain
    After the Electrical Safety Authority provides the electrical inspection “Connection Authorization” directly to Alectra Utilities, Alectra Utilities installs the bi-directional generation meter.

    Alectra Utilities will work with the customer to set up the appropriate settlement arrangement based on the project type.

What initiatives are available?

Net Metering

Electricity consumers in Ontario who produce some of their own power from a renewable resource may take advantage of the “net metering” initiative. Net metering allows you to send excess electricity you generate from renewable resources to the distribution system for a credit toward your energy costs. In essence, it’s a “trade” of electricity you supply against electricity you consume. Net-metered customers can now pair energy storage with renewable energy systems.

For more information about the net metering program, please see the Ontario Regulation 541/05 - Net Metering and Ontario Regulation 274/18 – Siting Restrictions.
