4. PGRRBen Richard’s 12/21/2016 E-mail PGDTF: Attached please find my first cut at the Draft PGRR for compliance with TPL-007-1 Requirement 1. This document will need to receive full ERCOT internal review before being submitted to ROS and perhaps before being submitted to PLWG for approval.  Accordingly, it is being offered to you for comments before having received full ERCOT internal review, as well as in parallel to ongoing ERCOT review, so please duly note this. I initially included dates and relative dates in this document but removed them after discussions with Mike J and while interpreting the “Guidelines for Creation/Modification of Planning Guides” to suggest that details would best be including in working group procedural documents instead of the Planning Guides (See “Guidelines for Creation/Modification of Planning Guides” http://www.ercot.com/committee/plwg ).  I subsequently submitted them without dates for a first cut review by Jeff.  Yet, Jeff’s first cut comments indicated that he felt we need the dates so I left his comments in the attached along with my responses as additional points for discussion. Michael Juricek – 1/11/2017 PGDTF Meeting

5. PGRRContinued Also, below are some potential, best case scheduling, sponsoring scenarios for comparison.  The TSP/RE sponsor for posting appears to be least likely.  And, as I understand it, since PGDTF is a task force and not a working group, PGDTF would need ROS to direct it to sponsor this PGRR creating some scheduling concerns.  Yet, I still have scheduling concerns with ERCOT sponsoring this PGRR, receiving comments from PGDTF on 1/11/17, and submitting to RevisionRequest@ercot.com the next day (1/12/17), so we still need to sort through all of this and your comments would be appreciated.  The attached document is being offered to you for comments under the assumption that I will be the one to sponsor it as an ERCOT Planning Engineer.
