Community Engagement
The IESO continues to engage with communities to seek input to help inform planning activities. See Key Resources below for the latest planning documents.
To keep pace with the rapid growth and economic development in the Renfrew region, the IESO implemented a streamlined regional planning process by conducting the Scoping Assessment in an accelerated manner. This enabled the Technical Working Group (comprising the IESO, Hydro One Networks Inc., and Ottawa River Power Corporation) to move directly into the development of an Integrated Regional Resource Plan (IRRP) for the Renfrew region.
This approach reflected feedback received through stakeholder engagement and aligned with government priorities around economic development. This plan will cover the entirety of the region and commenced on September 16, 2026.
This work will build on the 2022 Renfrew IRRP, which included recommendations for a line refurbishment between Chalk River and Petawawa that is expected to be completed in December 2027 and the replacement of autotransformers in Des Joachims Distribution Station in Laurentian Hills that was completed in June 2026.
Engagement will continue throughout the development of the new IRRP with more details to follow. The Renfrew engagement webpage is a source of ongoing information related to regional planning activities, including upcoming engagement opportunities.
