Pending Nodal Protocol Revision Requests (NPRRs)
# Title Description Date Posted Sponsor Urgent Protocol Sections Current Status Effective Date(s)
NPRR956 Designation of Providers of Transmission Additions This Nodal Protocol Revision Request (NPRR) modifies Section to align with section 37.056 of the Texas Utilities Code, as amended by SB1938 86(R), which became effective on May 16, 2019. As amended, section 37.056 authorizes the Public Utility Commission of Texas (PUCT) to grant a Certificate of Convenience and Necessity (CCN) only to a Transmission Service Provider (TSP) that owns the Facilities to which a proposed Transmission Facility addition will interconnect, or to the lawful designee of such a TSP. If more than one TSP owns Facilities to which a proposed addition will interconnect, the PUCT may issue a CCN to each such TSP to construct the needed Facilities in “separate and discrete equal parts,” unless the TSPs agree to a different allocation of responsibility. SB1938’s allocation of project responsibility based on ownership of the Facilities to which an addition interconnects is consistent with the Protocols’ longstanding assignment of responsibility based on ownership of the Facility endpoints. For the sake of consistency, however, ERCOT proposes to revise Section to more closely comport with the language of the statute. ERCOT notes that revised Section applies not only to those projects requiring a CCN, but also to other Tier 1 projects that may not require a CCN and therefore do not come within the coverage of section 37.056. This is consistent with the Protocols’ existing allocation rules, which have long assigned responsibility for all Tier 1 and 2 projects. ERCOT proposes to incorporate section 37.056’s assignment rules into a new paragraph (2). ERCOT proposes to modify paragraph (1) to recognize that ERCOT’s role, upon completing an independent review, is simply to identify the owners of the existing facilities, rather than to formally designate transmission providers. ERCOT also proposes to remove language from paragraph (1) which contemplates that ERCOT may determine project responsibility in the event of a disagreement between TSPs and may assign responsibility to a new TSP when the originally assigned TSP has not diligently pursued the project. Both of these provisions are inconsistent with SB1938, which contemplates no such role for ERCOT. ERCOT also proposes new paragraph (3), which would establish an explicit mandate that the TSP diligenty pursue the project. Although such a mandate is already implicit in provisions that establish the designation of providers, ERCOT suggests that stating this more explicitly will provide greater transparency that responsibility for a project entails a duty to pursue the completion of that project. ERCOT notes that “TSP” as used in the Protocols includes Municipally Owned Utilities (MOUs) and Electric Cooperatives (ECs). Finally, ERCOT proposes revisions to Section, Regional Planning Group Acceptance and ERCOT Endorsement, to provide that ERCOT will issue a Market Notice instead of sending an acceptance letter or endorsement letter, following Regional Planning Group (RPG) acceptance of Tier 3 projects, and ERCOT’s endorsement of Tier 1 and Tier 2 projects. This change will ensure that all TSPs (and other Market Participants) receive documentation showing completion of the ERCOT review process. ERCOT notes that because SB1938 is already effective, ERCOT must comply with the amended statute irrespective of the status of this NPRR. Thus, to the limited extent ERCOT’s existing Protocols conflict with the statute, ERCOT is already precluded from complying with those provisions. ERCOT is currently developing independent review reports for several projects and will ensure that its processes comport with the amended statute as it develops those reports over the next few months. 07/02/2019 ERCOT No,, Pending
NPRR981 Day-Ahead Market Price Correction Process This Nodal Protocol Revision Request (NPRR) ensures awarded Day-Ahead Market (DAM) transaction quantities are final when they are posted and allows Market Participants impacted by an error to utilize the Alternative Dispute Resolution (ADR) process. 11/07/2019 Luminant No 4.5.1 and 4.5.3 Pending

NPRR1067 Market Entry Qualifications, Continued Participation Requirements, and Credit Risk Assessment This Nodal Protocol Revision Request (NPRR) strengthens ERCOT’s market entry qualification and continued participation requirements for ERCOT Counter-Parties i.e., Qualified Scheduling Entities (QSEs) and Congestion Revenue Right Account Holders (CRRAHs), classifies information provided in the background check and credit scoring process as Protected Information, modifies application forms for QSEs and CRRAHs, and adds a new background check fee to the Fee Schedule. This NPRR makes the following modifications to Section 16: (1) Creates a new background check process as a part of ERCOT’s review of current and prospective Counter-Parties; (2) Authorizes ERCOT to review current and prospective Counter-Parties to determine whether they pose an unreasonable credit risk to ERCOT; (3) Authorizes ERCOT to determine creditworthiness based on an ERCOT-calculated credit score, and allows ERCOT to require certain actions be taken by a Counter-Party to remain creditworthy. (4) Authorizes ERCOT to suspend a QSE or CRR Account Holder if it poses an unreasonable credit risk to; and (5) Authorizes ERCOT to terminate the registration of a Counter-Party if it is deemed an unreasonable credit risk that cannot be remedied. Further, this NPRR formalizes processes for ERCOT’s assessment of Counter-Party creditworthiness, and includes a credit scoring process to provide a consistent framework for review of creditworthiness. Credit scoring will incorporate assessment of both qualitative and quantitative (financial statement) information. In the event of a material change to creditworthiness, this NPRR also clarifies the means by which ERCOT may adjust Unsecured Credit Limits and/or Total Potential Exposure (TPE) to ensure that these adequately reflect the financial risk created by a Counter-Party’s activities under these Protocols. 01/27/2021 ERCOT No, 16.1.2, (new), 16.2.1, (new), 16.2.2,,,, 16.8.1, (new), 16.8.2,,,, 16.11, 16.11.1, (new) , (new), (new), 16.11.2 (new), 16.11.2, 16.11.3, 16.11.4,,,,,,, (delete), 16.11.5, 16.11.6,,,,,,,,,,,,,,,, 16.11.7, 16.11.8, Section 23 Form A Section 23 Form G, ERCOT Fee Schedule Pending
NPRR1070 Planning Criteria for GTC Exit Solutions This Nodal Protocol Revision Request (NPRR) will improve ERCOT planning modeling assumptions to more accurately reflect operations of the ERCOT market and include indirect benefits as allowed by the Public Utility Commission of Texas (PUCT) when evaluating exit alternatives for Generic Transmission Constraints (GTCs). 03/05/2021 EDF Renewables / Pattern Energy No 3.11.2 Pending
NPRR1084 Improvements to Reporting of Resource Outages and Derates This Nodal Protocol Revision Request (NPRR) allows ERCOT to provide important information about Resource Forced Outages and Forced Derates to the public in a more complete and timely manner. Specifically, these changes will require the entry of all Resource Outages and Forced Derates into Outage Scheduler, regardless of the duration of the Outage; require the entry of all Resource Forced Outages and Forced Derates into Outage Scheduler within one hour of the beginning of the Forced Outage or Forced Derate; require the entry of the reason for any Forced Outage or Forced Derate into the “nature of work” field in the Outage Scheduler. Note that, separate from this NPRR, ERCOT intends to significantly expand the cause codes included in the drop-down menu for the “nature of work” field; and remove the Protected Information status for any Resource Outage that occurs during an Energy Emergency Alert (EEA) or within 24 hours prior to the declaration of an EEA, or that extends into an EEA, to allow public reporting of the magnitude, duration, and causes of those Outages. 06/30/2021 ERCOT No, 2.1,,,, (new), and Pending
NPRR1085 Ensuring Continuous Validity of Physical Responsive Capability (PRC) and Dispatch through Timely Changes to Resource Telemetry and Current Operating Plans (COPs) This Nodal Protocol Revision Request (NPRR) improves the validity of the Physical Responsive Capability (PRC) calculation and dispatch by requiring quicker updates by Qualified Scheduling Entities (QSEs) to the telemetered Resource Status, High Sustained Limit (HSL), and other relevant information. 06/30/2021 ERCOT No,, 3.9, 3.9.1, 6.4.8,,, and 6.7.5 Pending

The second set of changes clarify offer submission and Reliability Unit Commitment (RUC) procedures after an OSA is issued. 01/25/2022 ERCOT No Pending
NPRR1126 Default Uplift Allocation Enhancement This Nodal Protocol Revision Request (NPRR) improves the parity of the default uplift allocation methodology by introducing a scalar to Congestion Revenue Right (CRR) activity and adjusting its contribution so it is solely based on an entity’s CRRs owned in the Day-Ahead Market (DAM). The default uplift methodology in this NPRR will apply only to Settlement Invoice short payments that occur on or after the NPRR effective date. A Settlement Invoice short payment occurs on the date an Invoice payment is due but not paid by the time set forth in the ERCOT Protocols. 03/21/2022 DC Energy No 9.19.1 Pending
NPRR1127 Clarification of ERCOT Hotline Uses This Nodal Protocol Revision Request (NPRR) clarifies which Entities are required to have Hotline and 24-hour, seven-day-per-week communications with ERCOT and requires that those Entities answer each Hotline call in order to proactively ensure situational awareness in emergency situations. 03/23/2022 ERCOT No 2.1,,,,, 16.2.1,, 16.19 Pending
NPRR1128 Allow FFR Procurement up to FFR Limit Without Proration This Nodal Protocol Revision Request (NPRR) sets a -$0.01 per MW lower Ancillary Service Offer floor for Fast Frequency Response (FFR) Responsive Reserve (RRS) rather than for other RRS categories, thereby allowing, depending on relative Ancillary Service Offers, FFR procurement up to the current FFR limit without proration with other RRS categories in the Ancillary Service procurement process. 03/25/2022 Hunt Energy Network No and Pending
NPRR1131 Controllable Load Resource Participation in Non-Spin This Nodal Protocol Revision Request (NPRR) changes Controllable Load Resource participation in Non-Spinning Reserve (Non-Spin) from Off-Line to On-Line Non-Spin. Consistent with On-Line treatment, this NPRR also sets a bid floor of $75 per MWh for Controllable Load Resource capacity providing Non-Spin, equivalent to the offer floor for a Generation Resource providing On-Line Non-Spin and adds the requirement that if the Qualified Scheduling Entity (QSE) also assigns Responsive Reserve (RRS) and/or Regulation Up Service (Reg-Up) to a Controllable Load Resource that has been assigned Non-Spin, there will be a bid floor for the sum of the RRS, Reg-Up, and Non-Spin Ancillary Service Resource Responsibilities of $75 per MWh. ERCOT notes that the cap on a Real-Time Market (RTM) Energy Bid addressed in paragraph (2) of Section, RTM Energy Bids, remains unchanged. 04/25/2022 ERCOT No 2.1,,,, and 6.7.5 Pending
NPRR1132 Communicate Operating Limitations during Cold and Hot Weather Conditions This Nodal Protocol Revision Request (NPRR) specifies that during local cold weather conditions, each Qualified Scheduling Entity (QSE) must update its Generation Resources’ and Energy Storage Resources’ Current Operating Plan (COP), Real-Time telemetry, and Outage and derate reporting to reflect any cold-weather limitations. This NPRR also requires each Resource Entity to provide Resource-specific cold weather minimum temperature limits, hot weather maximum temperature limits, and alternate fuel capability information in its Resource Registration data submitted pursuant to Planning Guide Section 6.8.2, Resource Registration Process, and update this information as necessary. 04/26/2022 ERCOT No 3.9 and 3.10.6 Pending

SUBST. R. 25.43, Provider of Last Resort (POLR). 05/10/2022 Texas SET No Pending
NPRR1135 Add On-Line Status Check for Resources Telemetering OFFNS for Ancillary Service Imbalance Settlements This Nodal Protocol Revision Request (NPRR) modifies the definition of the Real-Time Generation Resources with an Off-Line Non-Spin Schedule (RTOFFNSHSL) to allow non-zero values for this billing determinant only if the Resource was Off-Line when it telemetered OFFNS. This is to ensure accurate Settlement in the scenario where an On-Line Resource erroneously telemetered OFFNS. 05/17/2022 ERCOT No 6.7.5 Pending
NPRR1136 Updates to Language Regarding a QSE Moving Ancillary Service Responsibility Between Resources This Nodal Protocol Revision Request (NPRR) makes changes to reflect the logic that will be in place after the implementation of Fast Frequency Response (FFR) Advancement project, the next phase of implementation for NPRR863, Creation of ERCOT Contingency Reserve Service and Revisions to Responsive Reserve. Specifically, the NPRR adds new paragraph (5) of Section to align with language in Section 6.4.7. These changes are for clarity only, and do not modify the system design. The new paragraph (6) of Section is an additional check that needs to be in place to ensure a QSE does not replace a Regulation Service with Fast Responding Regulation Service (FRRS). This section does not need to be addressed in the FFR Advancement implementation, and it is ERCOT’s intent to implement this logic change in a future project. 05/18/2022 ERCOT No and 6.4.7 Pending
NPRR1137 Updates to Section 1.1 to Modify the OBD List Review Timeline and Other Clarifications This Nodal Protocol Revision Request (NPRR) replaces the annual requirement to review the Other Binding Documents List with a four-year review cycle, and reflects additions of Protocol Sections. 05/24/2022 Eric Winters Goff LLC No 1.1 Pending
NPRR1138 Communication of Capability and Status of Online IRRs at 0 MW Output This Nodal Protocol Revision Request (NPRR) requires each Resource Entity to ensure that the reactive capability curve submitted for any Intermittent Renewable Resource (IRR) accurately reflects the IRR’s reactive capability when it is not providing real power and at lower levels of real power output. 05/25/2022 ERCOT No 3.15.3, Pending
NPRR1139 Adjustments to Capacity Shortfall Ratio Share for IRRs This Nodal Protocol Revision Request (NPRR) replaces the usage of the Wind-powered Generation Resource Production Potential (WGRPP) and PhotoVoltaic Generation Resource Production Potential (PVGRPP) with the High Sustained Limit (HSL) of an Intermittent Renewable Resource (IRR) as reflected in the Current Operating Plan (COP), similar to treatment afforded to Resources that are not IRRs. This NPRR also makes a minor adjustment in Section, changing the name of a variable in a formula from HSL to RUCHSL in order to match the variable name in the Protocols to the data value available in the Settlement extracts. 05/25/2022 ERCOT No and Pending
NPRR1140 Recovering Fuel Costs for Generation Above LSL During RUC-Committed Hours This Nodal Protocol Revision Request (NPRR) proposes changes to permit Generation Resources recover their fuel costs when instructed to start due to a Reliability Unit Commitment (RUC) and operate above the Generation Resource’s Low Sustained Limit (LSL). Specifically, this NPRR makes the following changes: • Remove the Max (0) function from the Revenue Less Cost Above LSL During RUC-Committed Hours (RUCEXRR) equation for Resources that have been granted a fuel dispute; • Add a Reliability Unit Commitment Fuel Cost Adder (RUCFCA) to the Real-Time Energy Offer Curve Cost Cap (RTEOCOST) to represent the incremental cost of fuel for generation above LSL; and • Provide clarification to Protocol Section 9.14.7 to allow for the recovery of such fuel costs via RUC Settlements. 06/07/2022 ERCOT No and 9.14.7 Pending
NPRR1141 Require Notary Public for NCI and Notice of Change of Banking Information Forms This Nodal Protocol Revision Request (NPRR) requires the signatory to use a notary public when completing the Notice of Change of Information (NCI) form or Notice of Change of Banking Information form to update, amend, and/or correct previously provided information. 07/12/2022 Elmagin Capital LLC No 23E and 23P Pending
