Community Engagement

The IESO engages with local and regional communities to seek input to help inform planning activities.

Regional Planning Progress Update

A new regional electricity planning cycle has begun for the Greater Ottawa Region that will examine local growth and future electricity needs.

The IESO has developed a Scoping Assessment Outcome Report and Terms of Reference that identifies the need for a more comprehensive planning approach and development of an integrated regional resource plan (IRRP) for the Ottawa Area Sub-Region. It also includes the terms of reference that outlines the timing and details of the work to develop the electricity plan. This follows the completion of the Needs Assessment published by Hydro One in December 2022.

Following the completion of the previous regional planning cycle, the IESO is developing a long-term plan for the Ottawa 115 kV transmission system (ongoing), and outlined a long-term plan for the broader bulk system electricity supply to Ottawa.
