Renewable Energy

Distributed Energy Resources (DER)

 

MICRO GENERATORS ≤10kW

Distributed Energy Resources (DER) include solar panels, combined heat and power plants, energy storage facilities, and natural gas-fueled generators. 

Our Engineering Department assesses and approves the connection of all DER connections to our distribution system. 

1 MICRO DER APPLICATION

First, complete and submit the application found below.

       Micro Generation Application

2 ENGINEERING TECHNOLOGIST SITE VISIT

Grimsby Power will review the application and, once it is accepted, a Technician will visit the proposed installation site to gather information to put together the Offer to Connect/Service Layout.

3 Micro embedded CONNECTION AGREEMENT AND OFFER TO CONNECT/SERVICE LAYOUT

Grimsby Power will issue a Connection Agreement and Offer to Connect which outlines the requirements and Grimsby Power’s costs to connect the generator. If you decide to proceed with the project, you will be required to pay the connection fees detailed in the Offer to Connect/Service Layout.

4 DESIGN & BUILD

Once the micro generation facility has been built according to our requirements, you will need to apply to the Electrical Safety Authority for an electrical inspection.

5 FINAL CONNECTION

Grimsby Power will schedule a meter change to install the new bi-directional meter. Grimsby Power will also do the necessary work to ensure billing arrangements are set up based on the project type.

Technical Requirements

Grimsby Power follows the most recent version of the Hydro One TIR for technical interconnection requirements of DER:

Small, Mid-Sized and Large Embedded Generators >10kW

Distributed Energy Resources (DER) include solar panels, combined heat and power plants, energy storage facilities, and natural gas-fueled generators. 

Our Engineering Department assesses and approves the connection of all DER connections to our distribution system. 

1 PRELIMINARY CONSULTATION INFORMATION REQUEST

The first step is to complete and submit Preliminary Consultation Information Request. Grimsby Power will respond to this request and provide you with the connection details for the proposed project and outline the available capacity. At this time, Grimsby Power will also provide details for a Connection Impact Assessment through a Preliminary Consultation Report.

       Preliminary Consultation Information Request (PCIR & PCR)

2 CONNECTION IMPACT ASSESSMENT APPLICATION

After the preliminary consultation, complete and submit a Connection Impact Assessment Application complete with payment as per the CIA Study Fee Schedule.

       GPI Connection Impact Assessment Form

       GPI CIA Fee Schedule

3 CONNECTION IMPACT ASSESSMENT

Grimsby Power and any other affected Utility will perform a Connection Impact Assessment for the proposed generator. Grimsby Power will then issue the report(s) once they are complete. You will be allocated capacity on the grid upon completion of the Connection Impact Assessment by all Utilities involved.

Please Note: For generators connecting on a Utility shared feeder, that utility maybe required to perform its own Connection Impact Assessment. Details of Utilities involved will be provided during the Preliminary Application stage.

4 CONNECTION AGREEMENT/OFFER TO CONNECT

Grimsby Power provides you with a Connection Agreement for your proposed Generator. Included in the Connection Agreement is a Connection Cost Agreement. This Connection Cost Agreement serves as your Offer to Connect and provides a cost estimation specifying the scope of work to be performed either by you, Grimsby Power, or Upstream Utilities, in order to make the generation connection.  

If you decide to proceed with the project, you must sign the Connection Agreement, sign the Connection Cost Agreement, and make the required payments.

5 DETAILED DESIGN REVIEW & CONTRUCTION

You will be required to submit a Detailed Design Review to ensure all requirements for the connection have been satisfied. Grimsby Power will review the Detailed Design and provide feedback and/or approval.

Once the final design is approved you must complete the construction of the generation facility and then apply to the Electrical Safety Authority for an electrical inspection.

Concurrently Grimsby Power and the Upstream Utility (if required) will perform the necessary work required for the connection.

6 COMMISSIONING & CONNECTION

You will be required to complete and submit a Commissioning Plan and Commissioning Verification Report.

Depending on the Scope of the project, Grimsby Power may want to witness the commissioning activities.

After the Electrical Safety Authority provides us with the electrical inspection "Connection Authorization", Grimsby Power will connect the generator to our Distribution System to allow for completion of the commissioning activities.

7 FINAL AUTHORIZATION

Once all requirements and commissioning activities have been approved by Grimsby Power, we will issue an authorization letter that permits the generator to operate within the parameters of their connection agreement.

8 SUPPORT

As DER connections vary in scope and complexity, Grimsby Power will work closely with you during the entire project from application through commissioning.
