Important Information Regarding New CIA Applications (Form B) Timelines

Effective October 1, 2022, the Ontario Energy Board (OEB) has introduced new rules for reviewing CIA applications which will impact processing timelines. From the time that we receive your CIA application, Hydro One has 14 days to review your CIA application to determine if your application is both complete and includes correct information. Should we deem your CIA application to be incomplete or contains incorrect information, you (the applicant) will have 14 days to resubmit a revised application. When you submit a revised application, Hydro One will have a further 7 days to review the application. Any applicant that does not meet the timelines, may lose their place in our processing queue and may be required to re-apply as a new applicant.

Canada Greener Homes Initiative

In May 2021, the government of Canada introduced the Canada Greener Homes initiative to assist homeowners with making energy-efficient upgrades to their homes among other incentives. Some of these upgrades include but are not limited to the addition of solar panels. As part of the grant application process, it may be necessary to provide a letter of approval or permission for the interconnection of your grid-connected solar system. Should this be required, you may provide the offer to connect letter issued by Hydro One for < 10kW projects or a copy of your Connection Impact Assessment (CIA) for > 10kW projects. For more information about the grant, you can access the Government of Canada website: Eligible retrofits and grant amounts (nrcan.gc.ca).

Important News Regarding Amendments to the Planning Act for Renewable Energy Generation Facilities

The siting restrictions in O. Reg. 274/18 which were administered by electricity distributors such as Hydro One have been replaced by amendments to the Planning Act (Ontario) that puts siting and planning requirements for renewable energy generation facilities under municipal oversight.

If we have provided you with a Connection Impact Assessment ("CIA") and a Connection Cost Agreement ("CCA"), it does not mean that you are permitted to build your Generation project in the municipality where your Generation project is located. As such, we recommend, if you have not done so already, that you immediately discuss municipal permitting and approvals requirements with the planning department in the municipality where your Generation project is sited before you proceed.

On April 30, 2018, Hydro One increased the minimum load and thermal capacity for Brockville TS in the List of Station Capacity. If you have questions, please contact our Distribution Generation group at 1-877-447-4412.
