Regional Electricity Planning - Northwest Ontario

Forecasting and Planning

Regional electricity planning in the Northwest region of Ontario is underway. This engagement initiative will provide interested parties with an opportunity to offer input for consideration into the elements of an Integrated Regional Resource Plan (IRRP) anticipated to be complete mid-2022.

For regional planning purposes, Northwest Ontario includes the area roughly bounded by Lake Superior to the south, the Marathon area to the east, and the Manitoba border to the west. It includes the districts of Kenora, Rainy River and Thunder Bay.

Regional electricity planning takes 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.

All interested parties are invited to participate in this engagement initiative and may include but are not limited to:

  • Municipalities in the Northwest region within the districts of Kenora, Rainy River and Thunder Bay, as outlined on pages 4 and 5 in the 2021 Northwest Scoping Assessment Outcome Report
  • Indigenous communities in Northwest Ontario as outlined on pages 5 and 6 in the 2021 Northwest Scoping Assessment Outcome Report
  • Communities affiliated with Métis Nation of Ontario as outlined on page 5 in the 2021 Northwest Scoping Assessment Outcome Report
  • Local distribution companies (LDCs) who serve the region including Synergy North, Atikokan Hydro, Sioux Lookout Hydro, Hydro One (Distribution) and Fort Francis Power Corporation 
  • Transmitters who serve the region including Hydro One (Transmission)
  • Consumers and service providers

Northwest Technical Working Group - The Technical Working Group, consisting of the five LDCs in the region, the local transmitter and the IESO, will use this regional planning engagement initiative to consider input to develop the Scoping Assessment for the region.

Additional details on the IESO’s plans to engage communities and interested parties throughout the process are outlined in the engagement plan
