Designation of Providers of Transmission Additions |
This Nodal Protocol Revision Request (NPRR) modifies Section 3.11.4.8 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 3.11.4.8 to more closely comport with the language of the statute. ERCOT notes that revised Section 3.11.4.8 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 3.11.4.9, 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. |

Implement Nodal Dispatch and Energy Settlement for Controllable Load Resources |
This Nodal Protocol Revision Request (NPRR) changes the dispatch and pricing of Controllable Load Resources (CLRs) in response to items in Phase 1 of Public Utility Commission of Texas’ (PUCT’s) market design blueprint related to demand response and increasing the “...utilization of load resources for grid reliability”. Specifically, this NPRR is focused on the blueprint language discussing the pursuit of “…market modifications and technical measures to improve transparency of price signals for load resources, such as changing demand response pricing from zonal to locational marginal pricing (LMP)”. To address the above directive from the PUCT, this NPRR changes the market participation model for CLRs that are not Aggregate Load Resources (ALRs) such that they are dispatched at a nodal shift factor and settled for their energy consumption at a nodal price. |

Reliability Deployment Price Adder Fix to Provide Locational Price Signals, Reduce Uplift and Risk |
This Nodal Protocol Revision Request (NPRR) revises the Real-Time On-Line Reliability Deployment Price Adder (RTRDPA) to: send appropriate locational price signals to avoid counterproductive Load and Resource responses to current RTRDPA price signals; limit Resource payment to the actual “indifference payment” (consistent with its definition), thereby reducing associated uplift by eliminating current RTRDPA payments to Resources that exacerbate constraints and eliminating payments to available capacity not requiring an indifference payment; eliminate Ancillary Service Imbalance Payments or Charges (ASIP/C) associated with RTRDPA, thereby reducing the risk associated with providing Ancillary Services; provide Resources an indifference payment under Real-Time Co-optimization (RTC) to eliminate the potentially large incentive to ignore Base Point instructions; and provide a stronger locational price signal around Resources committed by the Reliability Unit Commitment (RUC) process or other reliability actions for congestion, thereby reducing RUC Make-Whole Payment-related charges and uplifts and appropriately compensating impacted Qualified Scheduling Entities (QSEs). |

Interconnection Requirements for Large Loads and Modeling Standards for Loads 25 MW or Greater |
This Nodal Protocol Revision Request (NPRR) and the related PGRR establish interconnection and modeling requirements for “Large Loads”—defined in this NPRR to refer to one or more Facilities at a single site with an aggregate peak power Demand of 75 MW or more. ERCOT proposes these requirements based upon its experience with the interim large Load interconnection process implemented on March 25, 2022, analysis of operational events, and the discussion of various issues concerning Large Loads explored by the Large Flexible Load Task Force (LFLTF). Additionally, this NPRR facilitates the addition of a new study process for Large Loads seeking to interconnect to the ERCOT system. This process is described in the accompanying PGRR. This NPRR also adds a requirement that any Resource Entity that adds 20 MW or more of Load at any site with an existing Generation Resource shall submit a new Reactive Power study. The study must demonstrate the continued compliance of the Generation Resource with Voltage Support Service (VSS) requirements. This NPRR also establishes specific Subsynchronous Oscillation (SSO) requirements for Large Loads and revises and supplements SSO-related definitions, in addition to clarifying existing SSO requirements. Furthermore, although the primary focus of this NPRR is Loads that are 75 MW or larger, this NPRR also establishes new standards for the identification and classification of a site with an aggregate peak Demand of 25 MW or more at a common substation in ERCOT Network Operations Model. Such information will provide ERCOT visibility of the locations of these Loads for operational and planning purposes. Finally, this NPRR adds a fee for Large Load Interconnection Study Requests to the ERCOT Fee Schedule. |

Dispatchable Reliability Reserve Service as a Stand-Alone Ancillary Service |
This Nodal Protocol Revision Request (NPRR) develops a stand-alone Dispatchable Reliability Reserve Service (DRRS) product that includes the following functionality: DRRS is added to the Protocols on top of Real-Time Co-optimization (RTC) and Energy Storage Resource (ESR) single-model Protocols; DRRS is offered, awarded, and paid in the Day-Ahead Market (DAM). DRRS is not co-optimized in the Real-Time Market (RTM); DRRS can be-self arranged and traded. However, there are no DRRS-only offers (i.e., virtual DRRS offers) allowed, as DRRS will not be co-optimized in Real-Time; DRRS can be provided by Off-Line Generation Resources; a new Resource Status code will be developed for Resources with an Ancillary Service Resource Responsibility for DRRS that have not been deployed by ERCOT; When looking to commit capacity during the Reliability Unit Commitment (RUC) process, RUC will give priority to committing Off-Line Generation Resources providing DRRS. This is accomplished because Off-Line DRRS Resources will appear to have lower start-up and minimum energy costs relative to other Off-Line Generation Resources in the RUC optimization; DRRS will have a failure-to-provide Settlement for Qualified Scheduling Entities (QSEs) that do not sufficiently preserve Resource capability for providing DRRS within their portfolio; DRRS deployments will be included in the Reliability Deployment Price Adder process, in alignment with other existing Protocol language for similar deployments; and QSEs that are short on their DRRS Supply Responsibility at the time of a RUC instruction will be allocated a portion of any RUC Make Whole charges prior to allocating those costs to the QSEs that are RUC Capacity Short. |

RTC+B Modifications to RUC Capacity Short Calculations |
This Nodal Protocol Revision Request (NPRR) reflects the modifications addressed in the Real-Time Co-optimization Plus Batteries (RTC+B) Task Force whitepaper to the Reliability Unit Commitment (RUC) Capacity Short calculations. These modifications were discussed in RTC+B Task Force meetings on February 21, March 19, and April 10, 2024 as part of RTC+B Task Force Issue No. 17 and were endorsed by TAC on April 15, 2024. This NPRR addresses limitations in the current RUC Capacity Short calculations by considering Ancillary Service sub-types and changes to the calculation process involving Regulation Down Service (Reg-Down). This NPRR also addresses changes required to align Protocol language with the recently-approved NPRR1204, Considerations of State of Charge with Real-Time Co-Optimization Implementation, as it relates to the RUC process. This NPRR implements an approach that continues the current policy (i.e., allocating costs in a manner consistent with cost causation) to first proportionally assign RUC Make Whole costs to Qualified Scheduling Entities (QSEs) that are determined to be short of capacity or Ancillary Service capability when the RUC decision was made and, if necessary, assign the remaining RUC Make Whole costs to QSEs based on Load Ratio Share (LRS). This NPRR continues to follow the TAC-approved RTCTF Key Principle No. 3 (12). |

ERCOT Staff analyzed reports in the MIS Secure Area, along with existing Protocols for posting requirements, and identified no ongoing basis for holding in the MIS Secure Area reports determined to contain only Transmission planning information for a market audience and not ECEII. In addition to moving reports that do not contain ECEII to the ERCOT website, this NPRR also conforms rules with current posting practices for maintaining on the MIS Secure Area ECEII lists of equipment in the Outage Scheduler; for making available in the Model On Demand (MOD) application the annual planning model data submittal schedule; and for posting on the ERCOT website weekly Demand forecasts, demand analyses for 36 months and beyond, metrics of forecast error, and assessments of chronic congestion. This NPRR also clarifies that the Technical Advisory Committee (TAC) publicly reviews the Major Transmission Elements (MTE) list that isn’t ECEII, rather than the High Impact Transmission Elements (HITE) list that is ECEII; that Private Use Network Load distribution factor data would be redacted from postings on the “ERCOT website” rather than on the “MIS”; and that ERCOT’s monthly evaluations of chronic congestion are posted on the ERCOT website. Finally, this NPRR strikes the requirement to post on the ERCOT website shift schedules for ERCOT Operations Staff – currently, ERCOT posts shift schedules redacted of individuals’ identifying information, making the postings of little or no public use. |

Incorporation of Congestion Cost Savings Test in Economic Evaluation of Transmission Projects |
This Nodal Protocol Revision Request (NPRR) incorporates the consumer energy cost reduction test as the congestion cost savings test in economic project evaluation to address recent amendments by the PUCT to 16 Texas Administrative Code (TAC) § 25.101 —specifically adding the requirements in § 25.101(b)(3)(A)(i). Consistent with the PUCT’s rule, this NPRR also preserves the production cost savings test as another standalone means to establish economic need for a transmission project. This NPRR also removes obsolete language regarding transmission projects’ benefits evaluation in paragraph (6) of Section 3.11.2. Additional details regarding how the congestion cost savings test will be performed are included in the Congestion Cost Savings Test Evaluation Guideline white paper, which will be available on the Planning page of the ERCOT website once finalized. ERCOT may also apply the longstanding Impact of Weather Uncertainty and Transmission Outages on Economic Project Evaluations white paper in the instances specified therein to evaluate the impact of weather uncertainties and the impact of including transmission outages on the congestion cost savings test, as it has for the production cost savings test. This white paper is also available on the Planning page of the ERCOT website. |

Correction to NPRR1197, Optional Exclusion of Load from Netting at EPS Metering Facilities which Include Resources |
This Nodal Protocol Revision Request (NPRR) corrects language in Section 11.1.6 which was implemented with the July 1, 2024 Protocols following Public Utility Commission of Texas (PUCT) approval of NPRR1197, Optional Exclusion of Load from Netting at ERCOT-Polled Settlement (EPS) Metering Facilities which Include Resources. The NPRR1197 2/8/24 PRS Report did not correctly reflect the PRS vote “to recommend approval of NPRR1197 as amended by the 2/7/24 Oncor comments as revised by PRS” in paragraph (6) of Section 11.1.6. This error carried through the ensuing 3/27/24 TAC Report and 4/23/24 Board Report, and was approved by the PUCT on 6/13/24. This NPRR aligns the language within Section 11.1.6 with the intended PRS action from February 8, 2024. |

Updated FFSS Fuel Replacement Costs Recovery Process |
This Nodal Protocol Revision Request (NPRR) implements several improvements to Firm Fuel Supply Service (FFSS) fuel cost recovery process. Specific changes include: Clarifying that Qualified Scheduling Entities (QSEs) representing FFSS Resources (FFSSRs) are able to restock reserved fuel using existing fuel inventories in storage to accelerate the restocking of fuel or based on new purchases. For fuel restocking using existing fuel inventories, the Firm Fuel Supply Service Fuel Replacement Cost may be based on: New fuel purchases made within 30 days after ERCOT approves the restock of the burned fuel as described in paragraph (5) of Section 3.14.5, Firm Fuel Supply Service; or the Fuel Oil Index Price (FOP) for the Operating Day the QSE received approval to restock fuel, which includes $0.05/gallon to cover the cost of transportation. |

Pre-notice for Sharing of Some Information, Addition of Research and Innovation Partner, Clarifying Notice Requirements |
This Nodal Protocol Revision Request (NPRR) permits ERCOT to provide ERCOT Critical Energy Infrastructure Information (ECEII) or Protected Information materials to a vendor or prospective vendor of ERCOT without a pre-notice of the provision of ECEII materials to a vendor or prospective vendor of a Market Participant if the vendor or prospective vendor has executed an appropriate confidentiality agreement. Additionally, this NPRR adds a definition of ERCOT Research and Innovation (R&I) and ERCOT R&I Partner to clarify notice requirements prior to those entities receiving Protected Information from ERCOT. This NPRR also adds Market Notices as an appropriate method of providing notice under the Protocols, does away with the antiquated requirement that notice sent by email of fax must be followed up with mailed notice or hand delivery, and clarifies who is required to receive notice and a Market Participant’s responsibility to subscribe for applicable Market Notice distribution lists. |
