19.10End-State Auctions for TCCs

Upon the completion of more sophisticated Aauction software, the ISO will perform an End-State Centralized TCC Auction, which will permit the Bids submitted by Aauction participants to determine the lengths of the TCCs sold in the End-State Centralized TCC Auction. The End-State Centralized TCC Auction will be held annually.  The date for the first End-State Centralized TCC Auction shall be determined by the ISO.  The period during which each TCC sold in an End-State Centralized TCC Auction is valid shall begin on the beginning date of a Capability Period, and shall conclude on the ending date of a Capability Period.

The ISO will determine the maximum duration and minimum duration of the TCCs available in the End-State Centralized TCC Auctions.  The ISO shall have the authority to determine the percentage of the available transmission Capacity that will be sold in each round of the End-State Centralized TCC Auction.  The ISO shall announce these percentages before the End-State Centralized TCC Auction.  The ISO shall also determine the periods for which TCCs will be sold in End-State Centralized TCC Auctions (e.g., TCCs valid during on-peak and off-peak periods, or TCCs valid during Winter and Summer Capability Periods).  The ISO may elect to vary the duration or the periods for which TCCs will be available from one End-State Centralized TCC Auction to the next End-State Centralized TCC Auction.

The End-State Centralized TCC Auction will not include separate Sub-Auctions for TCCs of different durations. Instead, TCCs of each permitted duration will be allocated as the result of the operation of a single Aauction.  If, for example, a Market Participant wishes to purchase a TCC beginning in the Summer Capability Period of 2003, and ending in the Winter Capability Period of 2004-2005, it would submit a single Bid for this TCC. If that Bid is a winning Bid, the bidder would be awarded a TCC valid for the entire two year-long period; if the Bid is a losing Bid, the bidder would not receive the TCC for any portion of this period.  The ISO will not specify in advance the portion of system transmission Capacity that will be used to create TCCs of differing durations.  Rather, the durations of TCCs awarded will be determined as part of the objective of the End-State Centralized TCC Auction, and will depend on the Bids submitted by participants in the End-State Centralized TCC Auction.

In a given round of the End-State Centralized TCC Auction, the Mmarket-Cclearing Pprice determined for a TCC that is valid for multiple Capability Periods will equal the sum of the Mmarket-Cclearing Pprices for shorter-term TCCs with the same Point of Injection and Point of Withdrawal, which in aggregate cover the same period for which the longer-term TCC is valid.  (For example, the price of a TCC that is valid from May 2001 through April 2003 would equal the sum of the prices in that round for (1) TCCs valid from May 2001 through April 2002 and (2) TCCs valid from May 2002 through April 2003.)

The End-State Centralized TCC Auction will include multiple rounds of bidding, as described elsewhere in this Attachment M.

Transmission Capacity that can be used to support TCCs sold in End-State Centralized TCC Auctions shall include all transmission Capacity except that necessary to support the following:  Original Residual TCCs that the Transmission Owners sell directly in advance of the End-State Centralized TCC Auction; any TCCs previously allocated (either in an Aauction or through other means) that have not been offered for sale in thisthe End-State Centralized TCC Auction; and transmission Capacity needed to support Grandfathered Rights.

The End-State Centralized TCC Auction will allow reconfiguration of the TCCs sold in the previous Aauctions.  An entity holding a five-year TCC, for example, may release a TCC for some or all of the period for which that TCC is valid for sale in the End-State Centralized TCC Auction.

If necessary, the ISO may elect to conduct a semi-annual Aauction to sell six-month TCCs between annual End-State Centralized TCC Auctions.  The transmission Capacity that can be used to support TCCs purchased in this semi-annual Aauction shall include the portion of the transmission Capacity sold in the previous End-State Centralized TCC Auction as six-month TCCs, as well as any other outstanding TCC whose Primary Holder elects to release it for sale in this semi-annual Aauction.

Notes:1.Where two different amounts of transmission Capacity are separated by a “/”, the first number shall indicate the transmission Capacity available for conversion to ETCNL TCCs in a Centralized TCC Auction held for a Summer Capability Period, and the second number shall indicate the transmission Capacity available for conversion to ETCNL TCCs in a Centralized TCC Auction held for a Winter Capability Period.
