Alert
Unfortunately, we are not able to proceed with your registration if you do not have the power to enter your company into a legally binding agreement with Oakville Hydro.
The net metering initiative may be used by electricity consumers in Ontario who generate some of their own energy from a renewable resource. Net metering enables you to send surplus electricity from renewable resources to the distribution system for a credit towards your electricity bill. For a successive 12-month period, excess generation credits can be carried forward to offset future electricity bills. Customers with net meters can now combine energy storage with renewable energy systems.
Find out more about the process: Contact us and we will provide you with the technical specifications, the approval process and how to get your net metering contract. You should also contact the Electrical Safety Authority of Ontario (ESA), as your system must be inspected and approved by the ESA to guarantee that it is correctly connected to the grid.
Investigate your alternatives for renewable energy: information can be provided by renewable energy organizations, advisors and suppliers. For urban clients, a solar system may be the best renewable energy choice as wind or water systems require ample space and may not be permitted under zoning regulations. In rural areas, wind, water or agricultural biomass energy may be an option.
Determine the size of the generation unit that will suit your needs: use your prior bills as a starting point to tailor your system to your individual energy demand. Since your credits can only be carried forward for 12 months, oversizing a generation system does not increase the benefits.

It is recommended that the design is provided to Oakville Hydro within 30 days.
Connection impact assessment
The customer submits a connection impact assessment application to Oakville Hydro for a chosen location and makes payment with the application. Information required includes the size of the generation facility; the type of generation facility; type and details of technology; fuel type; single line diagram; location; protection philosophy; and preliminary design of proposed interface protection. Oakville Hydro performs the connection impact assessment of the proposed generation on the distribution system. A Study agreement will be sent to the customer detailing requirements and cost.
A Hydro One Connection Impact Assessment (CIA) will be performed, if required.
The decision to proceed and install
Upon receiving a successful CIA the customer can choose to continue with the generation installation. A site visit will be scheduled to determine any site specific details of the project. An offer to connect will be sent to the customer detailing the cost as well as all requirements for the installation. Once the customer pays the offer to connect costs, both the customer and Oakville Hydro will commit to a schedule, a form of information exchange and the scope of work.
