Regional Electricity Planning – Southern Huron-Perth (Greater Bruce/Huron)

Documents referenced on this page, but not posted, can be obtained by contacting with a link to the web page that lists the document and advise whether it needs to be provided in an accessible format. Please allow a minimum of one business day for a response.

Regional electricity planning in the Greater Bruce/Huron region is underway. Based on the findings in the Scoping Assessment Outcome Report, a long-term electricity plan – or Integrated Regional Resource Plan (IRRP) – will be undertaken specifically for the southernmost portion of the Greater Bruce/Huron region – for the Southern Huron-Perth sub-region. This engagement initiative will provide interested parties with an opportunity to offer input for consideration into the elements of the regional planning process.

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
