As a follow-up to the September 30 Quarterly Bulk webinar, the IESO shared details of the portfolios of transmission investments under consideration, generation assumptions for each scenario in the energy model, the sub-zonal load forecast used in the energy model, and the revised zonal diagram demarking the sub-zones created for the energy model. The data tables and feedback form are available on the South and Central Bulk Planning webpage. Please submit feedback to engagement@ieso.ca by December 19.
