Regional Electricity Planning - South Georgian Bay/Muskoka

Regional electricity planning has kicked-off in the South Georgian Bay-Muskoka electrical region to ensure a reliable supply of electricity, and to support local growth and economic development. Regional planning looks at the unique needs of each region and considers wire and non-wire options and innovative resources to meet the needs. This engagement initiative will provide interested parties with an opportunity to offer input for consideration during the regional planning process.

Regional electricity plans take up to a 20-year outlook on every region in the province. The planning process provides an opportunity for participants 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.
