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.
