Review PRS Reports, Impact Analyses, and Prioritization
Nodal Protocol Revision Request (NPRR) 747, Revision of Voltage Control Requirements

Ms. Frazier stated the 7/6/16 ERCOT comments proposed an alternative solution to NPRR770 by adding the outaged Resource capacity information to the Ancillary Service Capacity Monitor. Mr. Anderson stated that if approved, NPRR770 would be implemented with NPRR495, Changes to Ancillary Services Capacity Monitor, and NPRR736, Updates to the Ancillary Service Capacity Monitor Display, realizing a cost savings of approximately $15-25k; however, with the increased scope the release date may be delayed to December.

NPRR768, Revisions to Real-Time On-Line Reliability Deployment Price Adder Categories
Market Participants discussed NPRR768. Kenan Ögelman reviewed the 06/20/16 ERCOT comments and requested PRS continue tabling NPRR768 until Public Utility Commission of Texas (PUCT) Docket 45624, Application of the City of Garland to Amend a Certificate of Convenience and Necessity for the Rusk to Panola Double-Circuit 345-kV Transmission Line in Rusk and Panola Counties is concluded.

Mr. Greer moved to recommend approval of NPRR782. Mr. Barnes seconded the motion. The motion carried unanimously.
NPRR784, Mitigated Offer Caps for RMR Units - URGENT
Market Participants discussed the merits of NPRR784. Opponents of the NPRR objected on the basis that it does not provide appropriate price signals, and further argued that Loads ultimately pay twice for the energy; first when the RMR Resource is contracted and second when the Resource is compensated for the energy it provides. Proponents opined that NPRR784 is consistent with the principles of an energy-only market and will lower uplift costs for Loads and make the costs more manageable. Proponents offered additional language expressly specifying that the Independent Market Monitor (IMM) may object to the value of the Mitigated Offer Cap for RMR Units. Market Participants also discussed the potential for a delay of the vote on the merits of NPRR784 to allow for further discussion.
Smith Day moved to table NPRR784. Greg Thurnher seconded the motion. The motion failed via roll call vote with seventeen objections from the Consumer (Occidental) Cooperative, (4) (Brazos, STEC, LCRA, Rayburn Country), Independent Generator (4) (Iberdrola, Talen, GDF Suez, Exelon), Independent Power Marketer (IPM) (3) (Morgan Stanley, CitiGroup, Tenaska), Independent Retail Electric Provider (IREP) (2) (Reliant Energy Retail Services, Noble Americas), IOU (2) (Luminant, CenterPoint Energy), and Municipal (CPS Energy) Market Segments. (Please see ballot posted with Key Documents).
Mr. Greer moved to recommend approval of NPRR784 as revised by PRS. Mr. Helton seconded the motion. The motion failed via roll call vote with ten objections from the Consumer (3) (Occidental, Sierra Club, OPUC), Cooperative (5) (Brazos, STEC, LCRA, Golden Spread, Rayburn Country), IREP (Direct Energy), IOU (Luminant) Market Segments, and three abstentions from the IREP (Noble Americas), IOU (CenterPoint Energy), and Municipal (Denton Municipal Electric) Market Segments. (Please see ballot posted with NPRR784 Key Documents.)[2]
Market Participants discussed the appeals process codified in the TAC Procedures. Due to lack of a subsequent passing vote, NPRR784 was deemed rejected by PRS pursuant to ERCOT Protocol Section 21.4.4, Protocol Revision Subcommittee Review and Action.
Review of Revision Request Language (see Key Documents)
NPRR785, Synchronizing WGR and PVGR COPs with the Short Term Wind and PhotoVoltaic Forecasts
Market Participants reviewed NPRR785 and discussed whether the language posed any compliance issues, and that a Qualified Scheduling Entity (QSE) is still obligated to update the Current Operating Plan (COP) according to the forecast or a lower number, according to any additional information it has.
Mr. Greer moved to recommend approval of NPRR785 as submitted. Barksdale English seconded the motion. The motion carried unanimously.
