What's in scope

2,075 acres at 501 Pearson Ranch Road — assembled under Black Mountain Power LLC. Parker County Appraisal District stripped the agricultural exemption on May 15, 2026.
75-megawatt natural-gas power plant — five turbines, 24/7 continuous operation. Approved by TCEQ in 2.5 weeks with no public process.
Statewide context — the same operator (Fort Worth Power Core LLC) holds TCEQ air permits at 14 sites across 11 Texas counties. Parker is one of fourteen.
Resident cost — under the standard 80% Chapter 312 abatement, each Weatherford ISD homestead would absorb $3,523 (Phase 1) to $47,199 (full Buildout) over the 10-year abatement period.
State-law constraint — HB 3 and SB 2 cap how fast local jurisdictions can raise rates. Most of the foregone revenue mathematically becomes service cuts (schools, county roads, hospital district, ESDs), not rate hikes.
