New Study Supports ERCOT’s Extra High-Voltage Plan for Texas Grid

AUSTIN — A new study shows that building more powerful electricity lines — called extra high-voltage energy transmission lines (EVH) — could significantly boost the Texas power grid’s ability to deliver electricity. This would mean more dependable power and lower energy costs for all Texans.

The study, conducted by Siemens PTI and commissioned by the Texas Energy Buyers Alliance (TEBA) and Google, found that higher capacity 765-kilovolt (kV) electricity systems would significantly outperform the standard 345-kV lines currently in use.
