Constrained off CMSC Payments to Importers and Exporters (SE-10)

The IESO has identified to the Market Surveillance Panel (MSP) an unintended consequence under the current market rules whereby market participants can structure their import offers or export bids to receive constrained off CMSC payment amounts that are judged to be inconsistent with market design principles and the intent of these payments. A stakeholder engagement plan has been developed to involve stakeholders in assisting the IESO to mitigate any unintended consequences that exist with respect to CMSC payments to importers and exporters.
