Q4 Reliability Outlook Now Available
December 22, 2022
Ontario’s power system is prepared for the next 18 months, with sufficient electricity resources expected to be available to meet customer needs. However, tightening conditions on the grid may require active outage management and increased import volumes during certain periods.
The IESO expects to have sufficient reserves for the winters of 2022/23 and 2023/24. Reserve shortages have the potential to appear in summer 2023, primarily as a result of coincident generator outages. The IESO is working with participants to reschedule outages and maintain system adequacy through this period. If outages cannot be moved, Ontario may have to rely on more supply from other jurisdictions and/or additional operating procedures in order to ensure reliability under extreme weather conditions.
The full report is available on the IESO website.
