Transmission Rights Auction update

February 23, 2017

On March 1, the IESO will implement changes to the Transmission Rights (TR) Auction process. These changes include an introduction of a monthly financial report as well as updates to the long-term (LT) & short-term (ST) pre-auction reports.

Details of these changes were presented to stakeholders in December 2016. The presentation is posted on the Transmissions Rights Market Review stakeholder engagement web page.

Starting with the May ST auction, the calculation of the number of TRs offered will be based on the revised process and pre-auction reports will be published in the new format. There are no changes to the April ST auction process.
