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. |

Related to NPRR1234, Interconnection Requirements for Large Loads and Modeling Standards for Loads 25 MW or Greater |
This Planning Guide Revision Request (PGRR) creates a new process for studying the reliability impacts of all Large Loads (as defined in the accompanying NPRR1234) seeking to interconnect to the ERCOT System. As with the Full Interconnection Study (FIS) required for proposed Generation Resources, this PGRR requires a Large Load Interconnection Study (LLIS) for each new Large Load meeting applicability requirements that is proposed to interconnect to the ERCOT System. Like the FIS, the LLIS will consist of a similar suite of studies conducted by one or more affected Transmission Service Providers (TSPs). This PGRR describes these studies in detail and establishes timelines for the review of these studies and the completion of other steps in the interconnection process. This PGRR also: requires all Large Loads evaluated via the LLIS to be included in the existing quarterly stability assessment prior to Initial Energization; adds additional reliability performance criteria for the inclusion and evaluation of Large Loads in planning studies; adds requirements that must be met prior to including a Large Load in the ERCOT Network Operations Model; and establishes required interconnection equipment for both Generation Resources and Large Loads. |

Update of LSIPA Compliance Attestation |
This Planning Guide Revision Request (PGRR) makes the Lone Star Infrastructure Protection Act (LSIPA) attestation in the Planning Guide consistent with the language in ERCOT’s existing Protocol Section 23, Form Q, Attestation Regarding Market Participant Citizenship, Ownership, or Headquarters in the Protocols. Specifically, it adds language that would permit an Interconnecting Entity (IE) or property owner to demonstrate compliance under LSIPA even if it has a subsidiary or Affiliate that falls under any of the citizenship or headquarter criteria of LSIPA, so long as the subsidiary does not have direct or remote access to or control of the project, the real property utilized by the project, Resource Integration and Ongoing Operations (RIOO), the Market Information System (MIS), other ERCOT systems, or any confidential data from such systems. |
