Operations
Operating Reserve (OR) is stand-by power or demand reduction that the IESO can call on with short notice to deal with an unexpected mismatch between electricity generation and consumption. The IESO schedules OR for every minute of every day to meet requirements set by the North American Electric Reliability Corporation (NERC) and the Northeast Power Coordinating Council (NPCC) to ensure power system reliability. The IESO has been experiencing an issue with OR where the amount of scheduled OR is not fully accessible. This issue could create challenges for the IESO to recover the supply-demand balance after a system event, and result in unfair cost to the market. In order to better understand and develop potential solutions to this issue, the IESO will be initiating an engagement to discuss this with stakeholders.
Additional details on the IESO’s plans to engage stakeholders throughout the process can be found in the engagement plan. All comments and enquiries on this engagement can be directed to engagement@ieso.ca.
