Bulk Electricity Planning - East Ontario

Forecasting and Planning

A new electricity planning study for East Ontario was completed in December 2022 to examine transmission equipment reaching end-of-life (EOL) in the Gatineau transmission corridor along with forecasted reliability concerns in the areas of Ottawa and Peterborough to Quinte West which are supplied by the circuits located within the corridor.

The associated engagement initiative provided interested parties with an opportunity to offer input for consideration into the study.

Bulk electricity plans consider a 20-year outlook and the planning process provides an opportunity for communities, stakeholders and interested parties to provide input about anticipated needs and priorities, and to contribute to the development of the options for meeting this area’s future electricity needs.

Interested parties were invited to participate in this engagement initiative including but are not limited to:

  • Local municipalities encompassed in the between the Greater Toronto Area (GTA) East and Ottawa, passing through Peterborough generally in the GTA East, Peterborough to Kingston, Greater Ottawa and Renfrew planning regions.
