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.
