The Independent Electricity System Operator (IESO) works at the heart of Ontario's power system. The IESO delivers key services across the electricity sector including: managing the power system in real-time, planning for the province's future energy needs, enabling conservation and designing a more efficient electricity marketplace to support sector evolution.
Ontario's power system is operating reliably through the COVID-19 outbreak. Please check this site for updates.
The IESO is continuously monitoring the changing situation to ensure the reliability of the Ontario power system. In addition to the conversations we are having with generators, transmitters and distributors, as well as our counterparts across North Ameri, IESO President & CEO Peter Gregg is committed to keeping Ontarians informed about IESO’s operations and how it is adapting its plans as new information becomes available.
