Summary
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).
