NOTICE DATE: March 18, 2013 NOTICE TYPE: M-A030113-02 NPRR SHORT DESCRIPTION: REMINDER - WebEx and implementation details for NPRR463 INTENDED AUDIENCE: CRR Account Holders, Counter-Parties, settlement and credit personnel DAYS AFFECTED: March 20, March 22, and April 1, 2013 LONG DESCRIPTION: On April 1, 2013, Nodal Protocol Revision Request (NPRR) 463, CRR Auction Structure Enhancements, shall become effective. NPRR463, which was approved by the ERCOT Board on June 19, 2012, replaces the annual Congestion Revenue Right (CRR) Auction with a semi-annual sequence of four consecutive six-month CRR Auctions, defined as CRR Long-Term Auction Sequences. As presented to and approved by the Technical Advisory Committee (TAC) on February 7, 2013, ERCOT will implement and execute the first Long-Term Auction Sequence in accordance with the TAC approved CRR Activity Calendar. The implementation of NPRR463 is a significant change in CRR market design, structure, and timing. In order to help the market with transitional issues, ERCOT will be hosting two WebEx meetings to present an implementation overview, including key dates, and to answer any questions from Market Participants. The intent is to cover the same standard material with each WebEx, so Market Participants are not expected to attend both sessions. The meeting dates are as follows: * Wednesday, March 20, 2013 (14:00 - 15:30 CPT) o http://www.ercot.com/calendar/2013/03/20130320-CRR * Friday, March 22, 2013 (10:00 - 11:30 CPT) o http://www.ercot.com/calendar/2013/03/20130322-CRR Protocols for NPRR463 will become effective on April 1, 2013, followed by the key dates and activities below that will be further reviewed on the market calls. * Long-Term Auction Sequence 1 (CRRs for July - December 2013) o Post Network Model - April 2, 2013 o Post Auction Notice and open Credit Window - April 10, 2013 o Credit Lock - April 29, 2013 o Bid submission close - May 2, 2013 o Results posted - May 16, 2013 * Long-Term Auction Sequence 2 (CRRs for January - June 2014) o Summary of dates from Credit Lock to CRR Results being posted - May 20 - June 6, 2013 * Long-Term Auction Sequence 3 (CRRs for July - December 2014) o Summary of dates from Credit Lock to CRR Results being posted - June 10 - 27, 2013 * Long-Term Auction Sequence 4 (CRRs for January - June 2015) o Summary of dates from Credit Lock to CRR Results being posted - July 1 - 18, 2013 Reminder that monthly auction activities are not changed by NPRR463 and will continue to run in parallel to the Long-Term Auction Sequences. As part of this implementation, CRR Auction Revenue (CARD) Extracts will start containing Bill Determinants with suffixes in the format of "YYYY-N-S" representing the year, number and sequence used for the corresponding Annual CRR Auctions. This will start with the July 2013 CARD Extract. ERCOT also plans to discuss NPRR521, Transitional CRR Auction Capacity Value for Initial CRR Long-Term Auction Sequence, on the market calls. NPRR521 was approved by TAC on March 7, 2013, and will be considered by the ERCOT Board on March 19, 2013. NPRR521 requests for the first auction sequence network model capacity to be increased from 60% to 70%. A Market Notice will be sent with the status of this NPRR after consideration by the ERCOT Board.
