Regional Electricity Planning – East Lake Superior

Regional electricity planning in the East Lake Superior region is underway. 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 inform the IESO about anticipated needs and priorities and to provide feedback on 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 – Bruce Mines, Chapleau, Hilton, Huron Shores, Jocelyn, Johnson, Laird, Macdonald, Meredith & Aberdeen Additional, Plummer Additional, Prince, Sault Ste. Marie, St. Joseph, Tarbutt & Tarbutt Additional, Dubreuilville, Wawa
  • Indigenous communities - Chapleau Cree First Nation, Chapleau Ojibwe, Garden River, Michipicoten, Brunswick House, Batchewana
  • Local distribution companies (LDCs) who serve the community including Algoma Power Inc., Chapleau PUC, Hydro One Distribution and Sault Ste. Marie PUC
  • Transmitters including Hydro One Networks and Hydro One Networks Sault Ste. Marie LP
  • Consumers, service providers and associations for the area

East Lake Superior Scoping Study Team - A Scoping Study Team consisting of the four LDCs in the region, the two local transmitters and the IESO will use this regional planning engagement initiative.
