Related to NPRR956, Designation of Providers of Transmission Additions |
This Planning Guide Revision Request (PGRR) aligns the Planning Guide with NPRR956. NPRR956 revises the Protocols to align with section 37.056 of the Texas Utilities Code, as amended by SB1938 86(R), which became effective on May 16, 2019. The NPRR imports SB1938’s language regarding project responsibility and clarifies that ERCOT does not designate providers of recommended Transmission Facility additions, but simply identifies the owners of the existing Transmission Facilities to which those additions will interconnect. Consistent with the NPRR, this PGRR proposes that ERCOT’s report to the Public Utility Commission of Texas (PUCT) regarding a recommended Transmission Facility addition will identify the owners of the existing Transmission Facilities to which the addition will interconnect. |

Addition of Proposed Generation to the Planning Models |
This Planning Guide Revision Request (PGRR) outlines the additional generators that may be included in the planning models to address the generation shortfall introduced by the implementation of the new requirement from House Bill (HB) 5066 (88th Legislature) and unprecedented load growth in Texas. This PGRR also adds a supplemental generation sensitivity analysis for Tier 1 Regional Planning Group (RPG) project evaluation to minimize the impacts of the additional generation on transmission project evaluation. Minor revisions are also made in Sections 5.2.1 and 5.3.2 to address a typographical error and clarify that certain modeling data is required prior to the stability study rather than to initiate the Full Interconnection Study (FIS). |

Interconnection Studies Reform for Dispatchable Loads |
This PGRR allows Interconnecting Large Load Entities (ILLEs) to submit an NPRR1188-compliant Controllable Load Resources (CLR) election to the reviewing Transmission Service Provider (TSP). TSPs treat the election as a CLR Election Study input, model the site as an NPRR1188-compliant CLR, and may authorize earlier energization when constraints can be mitigated by dispatch down to the CLR Low Power Consumption (LPC), which may equal zero for the CLR. All Load would still be studied for delivery of their full capacity with timelines for firm network service outlined in the Load Commissioning Plan (LCP). Additionally, this PGRR directs that each proposed Large Load that elects to be studied as a CLR will be studied using the LPC and Maximum Power Consumption (MPC) provided as part of project information described in Section 9.2.2, Submission of Large Load Project Information and Initiation of the Large Load Interconnection Study (LLIS). It further directs that for the purposes of the Large Load Interconnection Study Methodology, CLRs will be studied assuming registration and qualification under NPRR1188 or any successor provision. Finally, this PGRR prohibits a CLR from using this program if it would impair a previously submitted Large Load’s requested energization date or energization capacity and that ERCOT may specify Interconnection Reliability Operating Limits (IROLs) or other reliability related transmission limits which cannot be resolved with CLR dispatch. |

Dynamic Model Submission and Review Requirements for Large Loads including Large Electronic Loads |
This Planning Guide Revision Request (PGRR) clarifies requirements for submitting dynamic model data for Large Loads to ensure accurate representation of each Large Load in ERCOT’s models. The PGRR requires submission of this data using formats compatible with the software platforms described in the Dynamic Working Group Procedure Manual (i.e., PSS/E, PSCAD, and TSAT). This PGRR also requires model quality tests demonstrating voltage ride-through capability for all Large Loads and converter model validation reports benchmarking PSCAD models against actual hardware tests for all Large Electronic Loads (LELs), ensuring high-quality and accurate models. In addition, this PGRR clarifies that material changes to a Large Electronic Load that could impact ride-through capability must be reviewed through the LLIS process before implementing the change. Furthermore, the PGRR clarifies that an Interconnecting Large Load Entity (ILLE) must meet the dynamic data submission requirements before initiating a dynamic stability study. The same dynamic data submission requirements are applicable whenever dynamic data is required to be submitted in accordance with the prerequisites specified in the current paragraph (5) of Section 5.3.5, Quarterly Stability Assessment. Finally, the PGRR requires the ILLE to submit updated dynamic models for the “as-built” LEL facility prior to requesting Initial Energization along with documentation identifying any differences from previously submitted model data used in the ERCOT quarterly stability assessment (“QSA”) and an attestation that the as-built data reflect the actual field settings. |
