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
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
NPRR1143 Provide ERCOT Flexibility to Determine When ESRs May Charge During an EEA Level 3 This Nodal Protocol Revision Request (NPRR) allows ERCOT the ability to decide when Energy Storage Resources (ESRs) may charge during an Energy Emergency Alert (EEA) Level 3. 07/27/2022 ERCOT No Pending
NPRR1144 Station Service Backup Power Metering This Nodal Protocol Revision Request (NPRR) provides a limited exception to the requirement that all loads included in the netting arrangement for an ERCOT-Polled Settlement (EPS) Metering Facility only be connected to the ERCOT Transmission Grid through the EPS metering point(s) for the Facility. The exception would allow no more than 500kW of auxiliary Load connected to a station service transformer to be connected to a Transmission Service Provider’s (TSP’s) or Distribution Service Provider’s (DSP’s) Facilities through a separately metered point using an open transition load transfer switch listed for emergency use. 07/27/2022 Plus Power No Pending
NPRR1145 Use of State Estimator-Calculated ERCOT-Wide TLFs in Lieu of Seasonal Base Case ERCOT-Wide TLFs for Settlement This Nodal Protocol Revision Request (NPRR) changes the 15-minute level ERCOT-wide Transmission Loss Factors (TLFs) that are used in the Settlement process from seasonal base case TLFs to State Estimator-calculated TLFs in Energy Management System (EMS). It also clarifies the use of Non-Opt-In Entity (NOIE) deemed actual TLFs to remove behind-the-meter Transmission Losses. 07/27/2022 ERCOT No 2.1, 13.1.1, 13.1.2, 13.2.2, 13.2.3, 13.2.4, 13.2.5, 13.2.5 (new), 13.4, 13.4.1 Pending
NPRR1146 Credit Changes to Appropriately Reflect TAO Exposure This Nodal Protocol Revision Request (NPRR) makes changes to credit provisions related to Trading Activity Only (TAO) Qualified Scheduling Entities (QSEs) that appropriately reflect their credit exposure. Specific changes include: eliminating the Unbilled Real-Time Amount (URTA) for TAO QSEs; allowing TAO QSEs to request an M1 of about two days by agreeing to certain conditions including suspending Real-Time Market activities upon ERCOT notice (Day-Ahead Market activity is systematically restricted to Available Credit Limit); clarifying that a TAO QSE is a QSE that does not represent either Load Serving Entities (LSEs) or Resource Entities, thus ensuring that a QSE engaging exclusively in DC Tie exports and other trading activities will be classified as a TAO QSE; and determining Counter-Party’s Total Potential Exposure (TPE) by adding the separate credit calculations for the Counter-Party’s (i) QSEs that represent LSEs or Resource Entities, (ii) TAO QSEs that do not represent LSEs or Resource Entities, and (iii) Congestion Revenue Right (CRR) Account Holders. 08/10/2022 Rainbow Energy Marketing Corporation No,, and Pending

NPRR1155 Attestation Regarding Market Participant Citizenship, Ownership, or Headquarters This Nodal Protocol Revision Request (NPRR) amends the Market Participant eligibility criteria in Section 16, Registration and Qualification of Market Participants, by providing that an Entity is not eligible to register or maintain its registration with ERCOT as a Market Participant if the Entity meets any of the prohibited citizenship, ownership or headquarters criteria established in the Lone Star Infrastructure Protection Act (LSIPA), Texas Business and Commerce Code, Sections 113.002(a)(2)(A)-(b)(2)(B) or 2274.0102(a)(2)(A)-(b)(2)(B), added by Act of June 18, 2021, 87th Leg., R.S., Ch. 975 (S.B. 2116). The NPRR provides that if an Entity meets any of the LSIPA criteria solely due to the citizenship, ownership or headquarters of a wholly owned subsidiary, majority-owned subsidiary, or Affiliate, the Entity may be eligible to register as a Market Participant if it certifies that the subsidiary or Affiliate at issue will not have direct or remote access to or control of ERCOT’s Wide Area Network (WAN), Market Information System (MIS), or any data from such ERCOT systems. Any Entity that seeks to register as a Market Participant will be required to submit an attestation as reflected in the form Section 23, Form Q, Attestation Regarding Market Participant Citizenship, Ownership, or Headquarters, certifying that the Entity complies with the LSIPA criteria. If there are changes to a Market Participant’s citizenship, ownership, or headquarters such that the Market Participant meets any of the prohibited company citizenship, ownership or headquarters criteria identified in the LSIPA, then the Market Participant will be required to execute and submit a new attestation to ERCOT within ten Business Days of the change becoming effective. This NPRR amends the eligibility criteria for registration as an Independent Market Information System Registered Entity (IMRE) by adding a requirement that an Entity must have a genuine professional or business purpose for obtaining access to the MIS Secure Area to qualify for registration as an IMRE. ERCOT may determine, in its sole discretion, whether the Entity’s purpose qualifies for registration. 11/22/2022 ERCOT No 16.1, 16.1.3 (new), 16.15, 23M, and 23Q Pending
