Brant sub-region

The regional planning cycle begun in 2013 for the Brant sub-region was completed in 2015 and an Integrated Regional Resource Plan (IRRP) was released.

Community Engagement

The IESO engages with local and regional communities to seek input to help inform planning activities. Information on engagement initiatives for the Brant sub-region will be posted during the next active planning cycle for the area.

Regional Planning Process Outcome (IRRP)

The IESO’s regional planning process identified investigating opportunities for a demand response (DR) pilot in the Brant area. The IESO posted a draft Request for Proposals for this pilot in early Q4 2016 and engaged stakeholders to solicit feedback. Final versions of the RFP and Service Agreement were posted in December 2016 and the submission window for proposals closed in February 2017. For more information about this engagement initiative, see Brant Local Demand Response Pilot.

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.

IRRP Working Group - Next Steps

A Working Group consisting of the local distribution companies in the region, the local transmitter and the IESO will continue to use the regional planning process to identify and meet local electricity needs.

The Working Group consists of staff from Brantford Power Inc., Brant County Power Inc., Hydro One Distribution, Hydro One Transmission and the IESO.

Sub-region Overview

Brant is located on the Provincial Highway #403 in the centre of Southwestern Ontario and is part of the Province's Greater Golden Horseshoe area – it encompasses the County of Brant, City of Brantford and surrounding areas.

This sub-region has an estimated population of over 136,000 people, and the electricity demand mix is comprised of residential, commercial and industrial uses. Electricity supply to the area is provided by three step-down stations – Brant Transformer Station (TS), Powerline Municipal Transformer Station (MTS) and Brantford TS. The coincident peak demand of the three stations was approximately 250 MW in 2013. 

Historical Context

Additional transformation capacity, provided by the Powerline MTS, was added to this area in 2006. In 2012, Hydro One determined there was a near-term capacity need with the 115 kV transmission line supply to the area. In early 2013, the OPA (now the IESO) initiated the IRRP process as a result of this finding.
