Regional Electricity Planning- Chatham-Kent/Lambton/Sarnia

Forecasting and Planning

Regional electricity planning in the Chatham-Kent/Lambton/Sarnia (CKLS) region has been completed with the posting of the final Scoping Assessment Outcome Report that determined no further regional coordination is required. This engagement initiative provided 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 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.
