Texas Energy Crisis Re-examination of Tres Amigas Transmission Project

The Tres Amigas Superstation project was first proposed in 2010 to tie the Eastern, Western and Texas grid interconnections together via three 5-GW superconductive high-voltage direct current power transmission lines. For decades, Texas has run its own interconnection, now managed by ERCOT, specifically to avoid NERC regulations and standards. ERCOT has been willing to export power to Mexico because federal oversight is not involved. However, in 2018, Tres Amigas was able to interconnect 450 MW of wind from west Texas and bring the renewables energy to Sacramento and Los Angeles. ZG is initiating technical evaluation to re-vamp the Western/ Texas discussion.
