Forecasting Future Energy Demand for St. Lawrence
November 13, 2026
Forecasting demand is a critical component of system planning. It helps identify future energy needs, understand the factors driving demand, and inform decisions about the infrastructure and resources required to maintain a reliable and resilient grid. Demand forecasting also provides valuable insights into how Ontario's electricity system may need to evolve to support economic growth, electrification, and evolving customer needs.
As part of the St. Lawrence regional planning process, the IESO is hosting a webinar on November 30, from 2 to 3 p.m. to present a draft demand forecast over a 20-year horizon with an opportunity to provide feedback. Presentation materials will be made available in advance of the webinar.
