DAY AFFECTED:  September 1, 2017

LONG DESCRIPTION:  ERCOT will be implementing Nodal Protocol Revision Request (NPRR) 808, Three Year CRR Auction, on September 1, 2017.  To implement this NPRR, ERCOT will now hold a series of six consecutive six-month Congestion Revenue Right (CRR) Auctions in each Long-Term Auction Sequence (LTAS), which will span the next three years into the future. The first such LTAS will begin with the 2018.1st6.AnnualAuction.Seq1 CRR Auction. The CRR Network Model for this auction will be posted on September 19, 2017. Monthly auction activities are not changed by NPRR808 and will continue to run in parallel to the LTAS auctions.

The below table lists the CRR Auction Capacity percentages that will be used for each six-month auction in an LTAS.

Prior to running the Seq5 and 6 auctions that will serve as the CRR First Offerings for 2020, ERCOT will perform a Pre-Assigned CRR (PCRR) annual allocation for the 2020 PCRR Nomination Year. PCRR-eligible Non-Opt-In Entities (NOIEs) will be expected to submit their 2020 PCRR nominations during the nomination window of December 4 - 8, 2017. ERCOT will communicate directly with these NOIEs in the same manner as for previous annual allocations.

CRR Auction and PCRR allocation activity dates can be found on the CRR Activity Calendar posted at http://www.ercot.com/mktinfo/crr.

ADDITIONAL INFORMATION:  Pursuant to Protocol Section 21.6, Nodal Protocol Revision Implementation, ERCOT is required to provide notice as soon as practicable, but no later than ten days prior to implementation.
