Economic Dispatch of Linked Wheel Transactions (SE-45)

A wheeling-through transaction is a simultaneous import of energy into Ontario and export of energy from Ontario by a market participant (i.e. the market participant moves energy from one jurisdiction, through the Ontario grid and into another jurisdiction).

A linked wheeling-through transaction provides a means for a market participant to move energy through Ontario and ensure that the import energy is not diverted from the market participant’s intended customer in the export market. This provides protection to the market participant against exposure to the Ontario uniform market price but it does not eliminate the congestion risk that all intertie transactions face. When congestion is not present, the import leg is paid at the same Ontario price as the export leg is priced, and as long as the import and export leg quantities are the same, the market participant has no net exposure to the Ontario price.
