The regional planning process for the Southern Huron-Perth sub-region of Greater Bruce/Huron is underway with an Integrated Regional Resource Plan (IRRP) anticipated to be posted in Q2 2021. The IRRP will identify the future need of electricity and options to ensure an adequate and reliable supply continues to be provided for its residents and businesses.
The IESO engages with local and regional communities to seek input to help inform planning activities. Learn more about engagement on the current planning cycle.
The Southern Huron-Perth sub-region is located at the southernmost portion of the broader Greater Bruce/Huron region and roughly encompasses the municipalities of Bluewater, South Huron, Lambton Shores, Lucan Biddulph, Middlesex Centre, North Middlesex, Thames Centre, Zorra, Perth South, St. Marys and West Perth.
The Greater Bruce/Huron area is located in southwestern Ontario. The region comprises the counties of Bruce, Huron and Perth, as well as portions of Grey, Lambton, Wellington, Waterloo, Oxford and Middlesex counties.

Regional Planning Process Status
A new cycle of regional electricity planning commenced in 2019, with the completion a Needs Assessment by Hydro One and Scoping Assessment Outcome Report led by the IESO working with the LDCs and transmitter in the region. This cycle was triggered early due to an increasing amount of load connection requests received.
The first cycle of regional planning did not identify needs requiring regional coordination, and concluded in August 2017 with the release of a Regional Infrastructure Plan (“RIP”) by the local transmitter (Hydro One). A Local Plan to address anticipated overloading of circuits was developed, and the condition is being actively monitored in the event mitigation measures needs to be triggered. Projects to address the frequency and duration of outages were also contemplated in the plan, and will be executed in the near-term. The expected load growth in the Kincardine area that was previously identified has been deferred based on an updated forecast.
