PGRR107  Related to NPRR1180, Inclusion of Forecasted Load in Planning Analyses

This Planning Guide Revision Request (PGRR) aligns the Planning Guide with NPRR1180. PGRR107 revises the Planning Guide to address recent amendments to P.U.C. Subst. R. 25.101, Certification Criteria, which became effective on December 20, 2022. Specifically, PGRR107 incorporates the requirement in P.U.C. Subst. R. 25.101(b)(3)(A)(ii)(II) for any review of project need conducted by ERCOT to incorporate the historical load, forecasted load growth, and additional load seeking interconnection, in ERCOT’s analysis, while recognizing that ERCOT’s Regional Transmission Plan will include only that load that ERCOT has determined to be credibly supported by quantifiable evidence of load growth. PGRR107 also requires a Regional Planning Group (RPG) project submitter to provide such information to ERCOT, when available, for inclusion in ERCOT’s planning analyses.
