3. CRR activity calendar - Overview
ERCOT is proposing to update the calendar to cover CRR activities through early 2019
Would like to review the draft calendar with CMWG and ask for their endorsement of an update
The LTAS Seq3 and 4 auctions are always tricky to schedule around the end of year holidays
Would like to discuss options to determine what is preferred for 2017 and beyond
Proposed format changes
Possible need to review protocol language (section 7.5.1(4)(b)(iii))

4. CRR activity calendar – description of changes
Dates from the currently approved calendar remain unchanged (through 2018.FEB.Monthly.Auction)
Except for adjustments to PCRR dates for 2017 (moved back by 2 weeks)
Added dates to cover CRR activity into beginning of 2019 (through 2019.MAR.Monthly.Auction) and PCRR dates for 2018
The same date selection patterns as used for previous years were applied to the draft to maintain Protocol requirements and consistency

5. CRR activity calendar – options for delaying Seq3 & 4 auctions around end of year holidays
Since beginning of LTAS auctions, it has always been difficult to schedule around end of year holidays
Staffing concerns for market participants and for ERCOT
Draft calendar contains multiple options for Seq3 & 4 auctions
Schedule right in line with previous auctions
Delay Seq3 by 2 weeks to avoid opening bid window soon after Jan. 1 (Seq4 to follow as usual)
Delay Seq3 until Jan (Seq4 to follow as usual)
Delaying auctions would have no impact on other auctions and would not impact ERCOT’s annual PCRR model build
Hope to choose the preferred option today

6. CRR activity calendar – proposed format change
Remove “Transaction Adjustment Period” column
Has only happened once (an annual auction in Oct. 2011)
An automated MIS operator message is posted right after the close of every auction bid window to notify whether or not a transaction adjustment period is needed
If needed, a Market Notice and a follow-up operator message would be sent
Would eliminate some clutter on the calendar

7. CRR activity calendar – next steps
ERCOT would like to get decisions today on preferred options for Seq3 & 4 auctions around end of year holidays and whether or not to remove “Transaction Adjustment Period” column from calendar
If decisions are reached, ERCOT plans to take the proposed calendar to WMS for endorsement on October 17 or November 2, 2016
And, then to TAC for final approval on October 27 or December 1, 2016

8. CRR activity calendar – considerations for future updates
Is there a need to review the calendar requirements in Section 7.5.1(4)(b)(iii-iv)?
Current language is a little confusing
Is TAC approval still needed for calendar updates?
If not, which group should approve?
Add column for “Pull Outage and NOMCR Data”
Provide specific date on which model builder will begin the process by pulling outage and NOMCR data
Use approved outages and NOMCRs for equipment changes available on this date

9. CRR auction notices
ERCOT Market Support Services is looking into ways to reduce Market Notice traffic
Cut down on distribution lists and extraneous notices
CRR team proposes no longer sending version of auction notices
Not required by protocol to send Market Notice
Auction Notice zip file posted on MIS Public meets all protocol requirements
Additionally, propose replacing current Word document in the zip file with a table of relevant auction information
Easier to read and cuts out unnecessary language
Is CMWG in agreement with these changes?

10. LTAS network model posting deadlines
Currently required by protocol to post no later than 20 business days before the auction (measured from bid window open date)
Is 20 business days still the desired timing?
Should we consider changing to 10 business days to match requirement for monthly auction network models?
Would allow for 2 more weeks to gather approved outages and NOMCRs
Is this worth losing 2 weeks to analyze the posted model?
Change would require an NPRR
ERCOT is seeking CMWG input

11. NPRR805 – Clarification for Multi-Month CRR Auction Offers
Clarifies that multi-month offers can be submitted into LTAS auctions, if the following conditions are met:
Strip of consecutive months
Months are within the auction period
Only for an LTAS auction
No change to current practice, just getting language into protocol
No impact NPRR

12. NPRR806 – Clarification for Designation of Capacity or Refund PCRRs
For annual PCRR nominations, clarifies how NOIEs are to designate whether they want to accept the refund option or the capacity option for their eligible resources
Choice is for entire year
Cannot select one option (refund or capacity) for some months of the year and the other option for the remaining months
Required because there is a 40% capacity factor applied over the entire year when that option is chosen
No change to current practice, just getting language into protocol ahead of CRR framework upgrade which will automatically populate the selected designation for every month of the year
No impact NPRR
