The following steps are for net metering projects and all other large DER projects greater than 10 kW.
Step 1: Submit a preliminary request
Complete the Preliminary Consultation Information Request: Distributed Energy Resource (DER) Connections (PDF, 181 KB) and email it to email@example.com. This step is optional, but we encourage you to complete the request. The request is free of charge and we provide you with connection details and allowable capacity.
Step 2: Request to connect to Toronto Hydro's grid
Complete the Connection Impact Assessment (CIA) Application (PDF, 4.3 MB) and submit it to us according to the Distributed Energy Resource (DER) Application and Connection Guidelines (PDF, 88 KB).
Note: If you’re submitting an application for a net metering project that involves a third-party generator, you must follow the requirements outlined on our net metering page.
Step 3: Sign and return your Offer to Connect with payment
Once you complete your application and meet our requirements, we’ll issue you an Offer to Connect / Connection Cost Agreement (OTC-CCA) that must be signed and returned to us with your final payment.
Step 4: Start construction
After design and technical parameters are finalized, you can start construction in accordance with the OTC-CCA. If a temporary disconnection (isolation) is needed, please make an online service request.
Step 5: Complete Electrical Safety Authority (ESA) inspection
After completing construction, you must make a request to the ESA for an electrical inspection.
Once you’ve installed the equipment and obtained ESA inspection and certification, you must send the ESA Certificate to firstname.lastname@example.org. Please include “ESA Notice of Inspection” and the project address in the email subject line.
Step 6: Start commissioning
Once we’ve received your ESA Certificate and reviewed your commissioning document package, we’ll arrange for a Toronto Hydro representative to come onsite and witness the commissioning process for the project. Then, we’ll prepare and issue a Connection Agreement.
Step 7: Meter installation
We’ll install the right meter for your DER.
Step 8: Connection complete
Congratulations, you're now connected to the grid!
