345kV Transmission Alternatives Analysis for ERCOT System Planning
This presentation by Robert Lona, a senior consultant at ERCOT, explores various alternatives for the 345kV transmission system connecting key areas such as Lamesa, Snyder, and Odessa to the broader ERCOT network. The analysis covers different cases including cost assessments and transmission line lengths. Notably, it includes proposed projects with a focus on HVDC lines and CREZ zones, providing insights into the financial implications and expected benefits for the Texas electricity market. The findings aim to inform future planning and decision-making.
