CRR Activity Calendar Carrie Bivens Manager, Forward Markets April 2017

CRR activity calendar - Overview ERCOT is seeking to update the calendar to accommodate the approval of NPRR808, Three Year CRR Auction Asking for TAC approval so that NPRR808 can go into effect with the next long-term auction sequences (LTAS) – approval required by May 1 Note that testing has not yet been done to verify that CMM can handle the additional inventory There are CRR and CMM upgrade projects that we need to avoid impacting There remains a risk that we won’t be able to implement NPRR808 on this timeline May need to invoke 7.5.1(4)(c)(iii), which provides that we may alter the calendar in the event of operational issues

CRR activity calendar – description of changes Adds sequences 5 and 6 for three year CRRs Establishes a consistent schedule with one monthly and one LTAS auction each calendar month Adds an off-cycle PCRR allocation for 2020 to occur in Nov/Dec 2017 Future annual allocation activities moved from spring to summer Reduces PCRR eligibility form response time to 2 weeks Avoids auction activities between Christmas and New Years Limits credit lock overlap to the extent possible Locked credit for each monthly auction will be released 1 Business Day after the credit lock occurs for each LTAS auction (except for December LTAS auctions)
