Regional Electricity Planning - Windsor-Essex

Forecasting and Planning

To ensure a reliable supply of electricity and support local growth and economic development, regional electricity planning has commenced for the Windsor-Essex electrical region. This region generally encompasses the area from City of Windsor and Town of Amherstburg going east towards the western part of the Municipality of Chatham-Kent.

Regional planning looks at the unique needs of each region, and considers a range of options to meet the area’s needs over a 20-year period. The process will be completed in Q4 2024 with the release of an Integrated Regional Resource Plan (IRRP).

We welcome your input on all aspects of this process, including anticipated community needs and priorities, and potential options for meeting this region’s future electricity needs. All interested parties are invited to participate in upcoming engagement initiatives, including but not limited to:

  • Municipalities including the City of Windsor, the Municipality of Leamington, the Towns of Amherstberg, Essex, Kingsville, Lakeshore, LaSalle, Tecumseh, and the Township of Pelee, as well as the western portion of the Municipality of Chatham-Kent
  • Indigenous communities including: Aamjiwnaang First Nation, Chippewas of Kettle and Stony Point First Nation, Munsee-Delaware Nation, Oneida Nation of the Thames, Chippewas of the Thames First Nation, Caldwell First Nation and Walpole Island First Nation.
  • Local distribution companies (LDCs) who serve the community and already participate as part of the Technical Working Group, including E.L.K. Energy Inc. (E.L.K.), Entegrus Powerlines Inc. (Entegrus), Enwin Utilities Ltd. (ENWIN), Essex Powerlines Corporation (EPL) and Hydro One Networks Inc. (Hydro One)
  • Transmitters (Hydro One Networks Inc.)
  • Consumers and service providers for the area

All interested parties are invited to participate in this engagement initiative.

Windsor-Essex Region Working Group - The Technical Working Group is lead by the IESO, and consists of the LDCs in the region and the local transmitter. The group will use regional planning engagement initiatives to incorporate input while developing the IRRPs for the region.
