IESO will implement new rules for breaking ties and reducing unfulfilled commitments in its capacity market ahead of its next auction Nov. 26-27.

After more than six months of operations under its Market Renewal Program, IESO is implementing “non-substantive” rule changes it says will improve clarity and alignment.

IESO’s plan to give its staff authority to set market parameters without approval by the Board of Directors has sparked a debate over the ISO’s governance and the role of stakeholders.
