Grid, Utilities & State Context

Grid Operator
ERCOT / AEP Texas Central transmission zone
Utilities
AEP Texas Central (TDU), Rio Grande Electric Co-op
State Permitting Process
No state siting board for solar in Texas. PUCT regulates utilities; ERCOT manages interconnection for ERCOT service territory (most of state); SPP governs Panhandle/northwest TX. County Commissioners Court governs unincorporated areas under Texas Local Government Code. Many rural TX counties have NO zoning authority — solar is essentially by-right. HB 2527 (2023) requires counties with ordinances to provide a 'reasonable' permitting framework. ERCOT interconnection queue severely congested — grid study delays of 2-4+ years common.
State Incentives
Texas has no state RPS mandate. Key incentives: Federal ITC (30% base + bonus adders for energy communities/domestic content). Property tax abatement via Chapter 312/313 successor frameworks (county-level negotiation required). ERCOT wholesale market provides strong merchant revenue stack. No state income tax benefits developer HQ decisions. USDA REAP available for rural projects.
