The Pre Auction Publication date represents the market rule requirement for the publishing of the Transmission Rights Market Pre Auction reports. Actual publishing may occur earlier.
The TR Bid Window normally opens at 09:00 EST of the first day and closes at 17:00 EST of the second day.
The maximum number of transmission rights that can be allocated in each auction is determined by the process described in Market Manual 4.4.
Transmission Rights Auction Settlement information can be found in the Financial Market Settlement Schedule and Payment Calendar.
The following table summarizes key activities and dates associated with the Transmission Rights (TR) Market in the calendar year 2021.
While it is the IESO’s intention to have the TR Auction activities occur on the dates proposed, the Market Rules allow for the TR Auction to occur anywhere within a specified period of time.
Should invoice payments not be received by the payment due date, the Transmission Rights shall not be issued to the TR bidder, and additional penalties shall be applied as outlined in Market Rules, Chapter 8, Section 4.20
