The IESO engages with local and regional communities to seek input to help inform planning activities.
A new regional electricity planning cycle has begun for Greater Ottawa that will examine local growth and future electricity needs. The new cycle started in late 2022 beginning with the Needs Assessment by Hydro One in December 2022.
The IESO is developing a Scoping Assessment Outcome Report and draft Integrated Regional Resource Plan (IRRP) Terms of Reference (if an IRRP is required) to determine the most appropriate planning approach going forward to meet the needs of the region.
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.
