PRR242 Waiver for Existing Contracts TNMP requests that Protocol Section 10.3.2.3 be amended for existing netting agreements which terminate between June 1, 2001 & December 31, 2001 by allowing an exception for generation netting which TNMP states does not otherwise affect ERCOT or competition. 04/27/2001  TNMP Yes 10.3.2.3 Withdrawn
PRR250 NOIE Consumption by ESI-ID Allows the QSE for a NOIE to see the consumption data for an ESI-ID for that NOIE. 06/20/2001  LCRA No 15.2 & 15.3 Withdrawn
PRR276 Adjust BENA Computation Adjust the computation of the Balancing Energy Neutrality Adjustment to more accurately assign the payments and charges to Load Serving Entities. 08/20/2001  Austin Energy/ CPS San Antonio Yes 9.6.1 Withdrawn
PRR277 Clarify SCF Fee Determination Sec. 7.3.3.1(2) of the ERCOT Protocols states that Â?Any shortages, not covered by ERCOTÂ?s line of credit, will be uplifted to all QSEs representing Load on a Load Ratio Share.Â? This PRR clarifies that such uplift should occur by adjusting the Forecasted Fee in the System Congestion Fund calculation, rather than uplifting congestion costs in excess of congestion fund revenues through the Balancing Energy Neutrality Adjustment, as is current practice by ERCOT. 08/20/2001  CPS-San Antonio Yes 7.3.3.1 Withdrawn
PRR281 Allowance for Aggregated Site-Specific Resource Dispatch Instructions (v2) This is version 2 of the original PRR submitted on 9/10/2001. This revision is intended to allow for site-specific dispatch of resources & would not be mandatory for all resource owners. V2 redefines sections of the Protocols where change is necessary & requests a Normal timeline for implementation. This PRR was originally entitled, Â?Change ERCOT Deployment Instructions to Settlement Meter SpecificÂ?. Due to the emergence of split metering, netting behind meters, & other factors the reference to instructions to the settlement meter was dropped in favor of the more accurate description of aggregated site-specific dispatch of resources. 05/24/2002  Calpine No various Withdrawn
PRR282 Define OOME as an Instructed Deviation 09/11/2001  Enron Yes Withdrawn
PRR284 Adjusted Computation of BENA Adjust the computation of the Balancing Energy Neutrality Adjustment to more accurately assign the payments and charges to Load Serving Entities. This PRR, combined with PRR277 (to be modified consistent with PRR280 such that all zonal congestion is collected via the SCF) will be effective during the CSC uplift period. 09/12/2001  Austin Energy/ CPS San Antonio Yes 9.6.1 Withdrawn
PRR286 Smoothing Algorithm This revision will change the calculation of the Schedule Control Error equation. 09/12/2001  AEP No 6.10.4.2 Withdrawn
PRR290 Balancing Energy Down Bids An across-the-board mandatory balancing down requirement can prevent QFs such as Gregory from providing contracted service to their thermal host. This reduces the reliability of QF service, threatens the thermal hostÂ?s service, potentially violates PURA §39.151 (l) by interrupting an internal process operation associated with an industrial generation facility, and is opposed to federal policies favoring QF development. 10/04/2001  Gregory Power Partners, L.P. No 4.4.5 Withdrawn
PRR293 Uncontrollable Renewable Resources Request Boxing of Existing Language since functionality does not exist to provide for this functionality and there is no viable manual work-around. 10/10/2001  ERCOT Yes 6.8.1.15.1 Withdrawn
PRR301 Over scheduling Load Imbalance Limits Provides an upper limit for Load Imbalance credits to QSEs when the QSEÂ?s load is significantly overscheduled. 11/28/2001  CPS-San Antonio No 6.9.5.2 Withdrawn
PRR304 Unexecutable Move-in The new 814_28 and 814_29 notification request/response will be used to communicate that the service order is unexecuted. The header will include the permit flag, the un-executable flag, and the same Reason codes as on the 650_02. 12/10/2001  Green Mountain Energy Yes 15.1.4.5; 15.1.4.7.1-4 [new] Withdrawn
PRR317 Revise Computation Procedure for TCRs Clarify and modify determination of CSC limits and TCRs. 02/05/2002  ERCOT Yes 7.5.2, 7.5.2.1, 7.5.2.2 Withdrawn
PRR320 Loads Participation in AS Market The testing and monitoring requirements for responsive reserves and non-spinning reserves prohibit a QSE from delivering such services at levels above defined limits. For testing, the QSE cannot deliver more than 105% of the requested reserves. For monitoring, the QSE cannot deliver more than 120% of the requested reserves. The proposed revisions eliminate these upper limits on testing and deployment for loads acting as a resource. 03/01/2002  PUCT-MOD Yes 6.10.3.2(4); 6.10.3.3(4); 6.10.5.4 & 6.10.5.5 Withdrawn

PRR339 REC for OOM Down This PRR is one of a group of PRRs [#s 334-340] that the submitter requested be considered as a single vote. To be fair to renewable resources without increasing the costs of Local Congestion, this PRR credits renewable resources that provide OOME Down service by awarding the resource RECs for energy not generated by the renewable resource due to providing the OOME Down service. This solution will also require an amendment to PUCT Substantive Rule 25.173. 05/20/2002  TXU Yes 14.7 Withdrawn
PRR340 Remove Market Solution Definition This PRR was originally part of a group of PRRs [#s 334-340] that the submitter requested be considered as a single vote. Remove the Â?Market SolutionÂ? concept as part of the mechanism for resolving Local Congestion. Renamed: Define OOME as an Instructed Deviation. The revised PRR allows for the deployment of dispatch instructions for OOME and does not remove the Market Solution definition. 05/20/2002  TXU Yes 2.1, 4.1.2, 4.5.3, 6.1.10, 6.1.11, 6.3.1, 6.4.2, 6.6.3.2.1, 6.7.1.2, 6.7.1.3, 6.7.8, 6.8.1.11, 7.1, 7.2.1.1, 7.3.2, 7.4.2, 7.4.3.1, 7.4.3.2, 7.4.3.3, 7.4.4, & 7.6 Withdrawn

PRR384 Protocol Preamble and Process for Advisory Opinion The first revision creates a preamble to the Protocols that outlines the expectations of market participants as they apply Protocols in the course of their wholesale activities. The second creates an opportunity for market participants to seek guidance regarding potential ambiguities or uncertainties in the application of the Protocols to wholesale activities by obtaining an opinion from an ERCOT Director. The opinion would be binding and could be relied upon unless or until the PUC or an ERCOT TAC or Board action dictated otherwise. 02/06/2003  ANP for the Code of Conduct Task Force Yes Preamble [new],1.5 [new], 1.6, 1.7, 1.8 Withdrawn
PRR399 IDR Replacement with Non-IDR Meter Requirements This revision allows 1) IDR installations where they are needed or required and provide the most effective utilization of this type of reporting to ERCOT; and 2) Removal of IDR installations that are no longer valid for a premise or ESI ID because of reduced load or consumption based upon 12-month consecutive usage data. 04/15/2003  Center Point Energy Yes 18.6.1 & 18.6.6 Withdrawn

PRR434 Adjustment to Allocation of REC Purchase Requirement This PRR would make adjustments to the annual allocation of REC purchase requirements to reflect changes in retail energy sales for a Competitive Retailer resulting from a final true-up or resettlement completed after the ERCOT notification deadline. 06/25/2003  TXU Energy No 14.1 Withdrawn
PRR435 Confidentiality of LSE Transaction Data This PRR would add transaction information submitted by an LSE to ERCOT or received by an LSE from ERCOT as a new category of protected REP specific information 06/30/2003  Green Mountain No 1.3.1 Withdrawn
PRR438 REC Timelines Revises reporting, issuing and mandated retirements requirements based upon change for final settlement. 07/02/2003  ERCOT No 14.2, 14.4.2, 14.6.2, 14.7, 14.10, 14.10.5, 14.11.1, 14.13, 14.14 Withdrawn
PRR455 Liability for QSE default on obligations to ERCOT and Responsibility for ERCOT Administration Fee Spreads risk of default of a QSE and ERCOT costs among both Loads and Resources. 08/25/2003  Green Mountain Energy No 9.4.4; 9.7.1 Withdrawn
PRR476 Ramp Rate Adherence During Local Congestion Currently, the ramp rates on individual resources are ignored during Local Congestion. This leads to Dispatch Instructions that are impossible to adhere to, especially when every unit running for a QSE is getting a unit specific instruction. Although a QSE may ignore category 4 instructions, they must still follow the category 1. In the event that every unit running for a QSE in a zone is getting a category 4, they all make up the category 1. As a result of the ramp rates being violated, SCE cannot be followed, which puts a strain on frequency which leads to regulation and balancing instructions. Further, the QSE can potentially be penalized with imbalance charges for not keeping SCE at 0. 11/13/2003  Exelon Yes 6.7.1.2, 6.10.7 Withdrawn
PRR480 Reporting of Switch and Move-In Data This PRR would require ERCOT to post on a monthly basis the number of residential and commercial customers served by the AREP and by all CRs combined, as well as the levels of switches and move-ins completed during the month by the AREP and CRs for residential and commercial customers. 12/04/2003  GMEC No 15.6 [new] Withdrawn
PRR494 Revise Forecasted Load Profile Post time ERCOT will publish forecasted Load Profiles for the next three business days no later that 5:30 a.m. in addition to there current posting at 10:00 a.m. This PRR also Clarifies that ERCOT will provide historical Load Profile data for up to the previous two years. 02/24/2004  Cirro Energy No 18.3.3 Withdrawn
PRR500 OOME Down Payments - Verifiable Costs The OOME Up payment mechanism provides for verifiable costs in excess of normal OOME Up payment. Having this same mechanism in the OOME Down payment structure provides fairness to Market Participants. 03/17/2004  Brazos Electric Cooperative No 6.8.2.3 Withdrawn
PRR503 Section 8 Coordination of Resource Outage Due to TSP Resource Entities that have arranged for redundant interconnection onto the ERCOT Transmission Grid, during the construction and interconnection phase, shall not be exposed to interruption of both interconnections at the same time, without the TSP arranging for station service and ERCOT taking on the responsibility of serving the Resource EntityÂ?s obligations. 03/19/2004  PSEG Texgen No 8.2.4 Withdrawn
PRR505 Elimination of OOME Down Payments This revision would eliminate the compensation currently provided for all Resources called upon for OOME Down and/or Local Balancing Energy Down (generic costs or generic bid limits would still be used as a deployment selection criteria, but not for settlement). Because the language changes desired for this PRR are in the same subsections of Section 6 & 7 as changes currently proposed in PRR485, a request currently in-flight, specific Protocol Section edits are not provided at this time (see Protocols Section 21.4.1(5), providing that suggested language for requested revisions is optional). Once PRR485 is considered by TAC and the BOD, the applicable baseline language will be redlined and submitted as comments to this PRR. 03/24/2004  City Public Service of San Antonio No 6 & 7 Withdrawn
PRR506 Revision to Short Payment Process Revises the timeline for uplift of partial payments. 03/29/2004  Constellation No 9.4.4 Withdrawn
PRR511 Clarification of PCR Eligibility The change is a forward-looking clarification of the eligibility for PCRs. The existing language is ambiguous regarding contractual changes between NOIEs and full requirement suppliers. The new wording has been vetted through the TNT Congestion Management Concept group and approved for inclusion in the CRR Whitepaper by the full TNT.In no case will the proposed change create new PCR eligible transactions. 04/05/2004  LCRA No 7.5.6 Withdrawn
PRR516 Curtailment Prioritization for Wind Generators Introduces the concept of using in-service date to determine curtailment priority in situations where only wind generators are needed to resolve local congestion Requires new WPGRs locating in the McCamey area to install Special Protection Schemes to limit their output. 04/30/2004  FPL Energy No 7.4.2, 7.8.8 Withdrawn
PRR524 Clarification of Timeline for Cost Submission Most disputes of the Initial Settlement Statements must be initiated, negotiated and resolved by the issuance of Final Settlement Statements. This PRR will extend the same requirements to the submission of verifiable costs. 06/07/2004  Direct Energy No 6.8.1.11, 6.8.2.2, 6.8.2.3, 6.8.3.1, 6.8.3.3 Withdrawn
PRR533 Definition of Transmission Facility Owner Responsibility associated with providing model data is not clearly defined in the Protocols. The use of Â?TDSPÂ? has not provided clear direction for owners, operators, and ERCOT regarding model data submission. Suggested removal of responsibilities associated with Outage Scheduling provides a streamline appropriate flow of information. 07/29/2004  LCRA No 2, 8.3.8, 8.8.2.1, 8.8.2.4, 12.4.4.1, 12.4.4.1.1, 12.4.4.1.2, 12.4.4.2.2, 12.4.4.2.3.1 Withdrawn
PRR539 OOMC Claw Back Correction Prevents payments for OOMC service from being negative (a charge) 09/01/2004  AEP No 6.8.2.2 Withdrawn
PRR549 Regulation Control During Abnormal Frequency Events This PRR revises Sections 6.5.3, 6.8.1.15.1, and 6.10.6 to establish an ERCOT frequency deadband of +/- 0.03Hz to aid in regulation control during abnormal frequency events. When ERCOT frequency is outside the deadband, any Qualified Scheduling Entity (QSE) that has a System Control Error (SCE) that is acting to return frequency to a level that is within the deadband will continue to send Dispatch signals to their Resources until the ERCOT frequency returns to a level that is within the deadband. However, in the case when ERCOT frequency is outside the deadband and, any QSE has an SCE error that is acting to move frequency further outside the deadband, that QSE will temporarily suspend sending signals to its Resources until ERCOT frequency returns to a level that is within the deadband. 10/08/2004  TXU No 6.5.3, 6.8.1.15, 6.10.6          Withdrawn
PRR552 Clarification of Relaxed Balanced Schedules Clarifies section 4.3.2 Schedule Components to ensure that QSEs may schedule Load or generation, even though they may not physically represent Load or generation. 10/18/2004  Coral No 4.3.2 Withdrawn

PRR631 Black Start Bid Procedures and Compensation for Testing This PRR establishes a process that requires ERCOT to perform the simulation studies (the cost of which will be uplifted to the entire market through the ERCOT Administrative Fee) of Black Start Resources called for in Protocol Section 6.10.3.6(1)(f), rather than require the simulation to be done by the prospective Black Start Resource owner before the final Black Start Service awards are made by ERCOT. In addition, this PRR establishes a payment mechanism to reimburse Resource Owners for costs incurred in the qualification and/or testing of Black Start Resources. 09/06/2005  TXU Wholesale No 6.10.3.6 Withdrawn
PRR645 Customer Information Repository This PRR documents the responsibilities of Competitive Retailers to provide Customer information to the third party for maintaining the Customer Information Repository.

PRR678 Allocation of RPRS Over-Collection to QSEs This PRR allocates any over-collection of funds caused by ERCOT deployment of RPRS to QSEs that are scheduling the excess capacity that offset the requirement for RPRS. 07/28/2006  TXU Wholesale Yes 6.8.1.16 â?? Settlement of NSRS Over-Collection (New); 6.9.2.1.2 â?? Replacement Reserve Uplift Charge Withdrawn PRS Review at the special August 2 PRS Meeting
PRR696 MAPE Publication This PRR would amend current Protocols to include the measure of forecast error (i.e., ERCOTâ??s Mean Absolute Percent Error, or MAPE).  Current protocols require ERCOT to provide a load forecast and the actual load.  This PRR would isolate the forecast for the Day Ahead market at 1600 hours and at midnight.  Additionally, the PRR would require ERCOT to post and maintain an up-to-date historical series for the monthly average MAPE data.  Lastly, this PRR would require ERCOT to segregate the weather forecast error from the overall load forecast error. 10/17/2006  Deutsche Bank No 4.2, Scheduling-Related Duties of ERCOT Withdrawn None
PRR712 Local Congestion Replacement Reserve Payment Methodology This PRR modifies the Local Congestion Replacement Reserve Service (RPRS) payment methodology to be identical to that of the Out-of-Merit Capacity (OOMC) payment methodology, as described in Section 6.8.2 .2, Capacity and Minimum Energy Payments.  This PRR also includes a “Max” function in the equation of startup payments in case there is a delay in the implementation of PRR676, RPRS Solution with Nodal RUC-Type Procurement and Cost Allocation. 02/19/2007  WMS No 6.6.3.2.1, Specific Procurement Process Requirements for Replacement Reserve Service in the Adjustment Period;  6.8.1.11, Local Congestion Replacement Reserve Payment to QSE;  6.8.2.2, Capacity and Minimum Energy Payments Withdrawn
PRR715 Simplifying the Dispute Process This Protocol Revision Request (PRR) removes the concept of â??lateâ?? disputes that can still be worked by ERCOT, and removes the concept of disputing settlement statements.  Instead, disputes that are filed with enough time for ERCOT to work them, as defined in the Protocols modified by this revision, will be worked and included in the next settlement statement if granted. 03/27/2007  Settlements and Data Aggregation Working Group (SDAWG) No 6.8.2.6, 9.1.2, 9.2.5, 9.5, 9.5.2, 9.5.3,  9.5.4,  9.5.4.1 (new), 9.5.4.2 (new) Withdrawn PRS Initial Language Review

PRR813 FIP Definition Revision

This Protocol Revision Request (PRR) revises the definition of Fuel Index Price (FIP) to correctly account for the timing difference between ERCOT’s application of the FIP in its systems (midnight to midnight) and the timing of natural gas prices reflected by the index (i.e., 10 AM to 9 AM).  The fuel price index published in Gas Daily, in the Daily Price Survey, under the heading “East-Houston-Katy, Houston Ship Channel” for any particular day reflects natural gas prices available to users from hour ending 10 AM of the particular day to hour ending 9 AM of the next day (i.e., the normal “gas day”).  This PRR also adds a new definition for the term “Gas Day.”

This PRR also proposes non-substantive administrative changes, such as correcting acronym and defined term usage and section references.  These are shown below with the author “ERCOT Market Rules.”		 05/29/2009  Luminant Energy Company LLC No 2.1, 6.8.2.1, 6.8.2.3 Withdrawn
