Regional electricity planning in the Greater Bruce/Huron region was completed in September 2021 with the release of a long-term electricity plan – Integrated Regional Resource Plan (IRRP) for the Southern Huron-Perth sub-region. This engagement initiative provided communities and stakeholders with an opportunity to offer input for consideration into the development of the IRRP. This engagement initiative provided communities and stakeholders with an opportunity to offer input for consideration into the development of the IRRP.

Regional electricity plans take a 20-year outlook on every region in the province. The planning process provides an opportunity for communities to tell the IESO about anticipated needs and priorities and to contribute to the development of the options for meeting this region’s future electricity needs.

Additional details on the IESO’s plans to engage communities and interested parties throughout the process are outlined in the Engagement Plan. All comments and enquiries on this engagement can be directed to
