PUCT approval of 765 kV for the Permian Basin import paths — the first extra-high-voltage transmission in ERCOT
765 kV, 3 import paths (approved 2025-04-24)observed
| Value kind | observed — Reported measurements, counts, and specifications keep the precision and scope stated by their source; an exact specification is not treated as a range. |
|---|---|
| Scope | Covers the plan and voltage approval only. Routing certificates (Oncor Longshore–Drill Hole; LCRA Bell East–Big Hill–Sand Lake) and energization (Oncor targeted December 2028) sit in separate dockets. In December 2025 ERCOT's board separately approved a 765 kV eastern backbone of about $9.4B and 1,109 miles; its eastern segments still need PUCT approval. |
