Evaluation of Compliance with Reactive Requirements |
This Planning Guide Revision Request (PGRR) defines ERCOT’s process for evaluation proposed Generation Resources’ ability to provide reactive power. Protocol Section 3.15, Voltage Support, defines reactive capability requirements for Generation Resources. Paragraph (3) of Protocol Section 16.5, Registration of a Resource Entity requires ERCOT to opine upon the capability of the proposed Generation Resource’s ability to meet these requirements. |

Related to NPRR1191, Registration, Interconnection, and Operation of Customers with Large Loads; Information Required of Customers with Loads 25 MW or Greater |
This Planning Guide Revision Request (PGRR) creates a new process for studying the reliability impacts of all Large Loads (those 75MW or more) that will be interconnected within 24 months. 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 (TSP). 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 requires a Customer proposing to interconnect such a Load—referred to as a “Large Load Interconnecting Entity”—to initiate such a request through ERCOT’s Resource Integration and Ongoing Operations (RIOO) system, which will leverage the efficiency of this existing tool to enable ERCOT and affected TSPs to submit, review, and confirm completion of the studies that are needed. This PGRR also requires some Large Loads to be evaluated as part of the existing quarterly stability assessment. This PGRR also adds additional Reliability Performance Criteria for the inclusion of Large Loads in planning studies. |

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. |
