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.

Long-term Auctions use summer maximum ratings to determine the maximum number of TRs that can be allocated. Short-term auctions for the months of May to October (inclusive) also use summer ratings to determine the maximum TR capability. Depending upon the application of the Confidence Factor, these auctions will only occur if there are unsold quantities from Long-term auctions (LT_YYYYMMDD) for the applicable period.

Transmission Rights Auction Settlement information can be found in the Financial Market Settlement Schedule and Payment Calendar.
