PGRR044 MIS Classification of GINR Study Information This Planning Guide Revision Request (PGRR) proposes to change the Market Information System (MIS) classification of certain studies undertaken as part of the Generation Interconnection of Change Request (GINR) process. Specifically, this PGRR would require ERCOT to post ERCOT’s security screening study and three parts of the Transmission Service Provider’s Full Interconnection Study—the steady-state, system protection, and facility study—to the MIS Secure Area, making that information available to all Market Participants. However, consistent with Nodal Protocol Revision Request (NPRR) 703, this PGRR would continue to require ERCOT to post all dynamic and transient stability studies and any sub-synchronous oscillation (SSO) studies to the MIS Certified Area for TSPs only. ERCOT expects that this PGRR will be revised in accordance with the categorization of interconnection study information stakeholders ultimately find appropriate in NPRR703. In addition, this PGRR would clarify that economic studies for transmission projects proposed as a result of a new GINR Project must be posted to the MIS Secure Area. This PGRR would also add the appropriate Market Participant category to the data set table where it indicates that certain information will be posted to the MIS Certified Area. Finally, this PGRR would clarify that the final stability study and any SSO study should be submitted to ERCOT separately from the remainder of the FIS to facilitate posting on the appropriate areas of the MIS. 04/29/2015 ERCOT No 5.4.8, 7.1 Approved
12/10/2015
PGRR045 Alignment with NPRR705, Provides Consistency for References to the End Date of the Generation Interconnection Process In the Resource Interconnection Handbook, the term “commercial operations” has a different meaning to Resource Entities and financial institutions involved in construction and financing of Generation Resources than it does in the context of performance testing by ERCOT for new Generation Resources. This Planning Guide Revision Request (PGRR) aligns the Planning Guides with NPRR705 by replacing various terms used to refer to the date on which Generation Resources complete the Resource interconnection process with the proposed defined terms “Commercial Operations Date” and “Resource Commissioning Date” to provide consistency for references to the end of the generation interconnection process. 05/20/2015 ERCOT No 5.3.2, 5.4.3, 5.4.5, 5.4.10, 5.7.1, 5.7.2 Approved
01/01/2016

PGRR053 Addition of Proposed Generation Resources to the Planning Models This Planning Guide Revision Request (PGRR) modifies the conditions that need to be met prior to including proposed Generation Resources in the planning models. This proposal includes limiting the initial data required for inclusion in the Steady State Working Group (SSWG) base cases to the data provided for the Full Interconnection Studies (FISs). ERCOT’s System Planning Monthly Status Reports consistently indicate a significant amount of proposed Generation Resources meeting all existing inclusion conditions (Standard Generation Interconnection Agreement (SGIA), applicable permits, notice to proceed, and financial security) with the exception of providing sufficient data required as indicated in the Resource Registration Glossary. The exclusion of the proposed Generation Resources from the Planning Models which have met all other inclusion conditions except for providing sufficient Resource Asset Registration Form (RARF) data has created a need to unnecessarily use extraordinary Dispatch conditions in the SSWG base cases. This PGRR will allow SSWG to utilize more representative generation Dispatch scenarios in their base cases. 09/29/2016 PLWG No 6.9; 8 Attachment B Approved
