765-kV Lines in West Texas Inch Closer to Reality

AI generated summary

The development of 765-kV transmission lines in West Texas is progressing, with ERCOT and stakeholders preparing to present information to regulators by May 1. During a recent workshop, ERCOT introduced a 765-kV study as part of its annual Regional Transmission Plan, which aims to address the growing demand for electricity in the oil-rich Permian Basin. The Texas Public Utility Commission has already approved a plan that includes both 345-kV and 765-kV infrastructure, with an estimated initial investment of $13 billion to $15 billion, although a final decision on voltage levels is pending until May 2025.

The proposed 765-kV Strategic Transmission Expansion Plan (STEP) is projected to cost approximately $32.99 billion and will involve the construction of nearly 2,500 miles of new 765-kV lines, along with upgrades to existing infrastructure. ERCOT anticipates that the higher-voltage lines will enhance economic and reliability benefits by efficiently transporting power over long distances, especially as demand is expected to exceed current capacity by 2030. The analysis suggests that the 765-kV option could significantly reduce congestion costs and energy losses, thereby improving overall grid stability in the region.
