The plan at Tres Amigas was to use superconducting equipment and short-range superconducting cables on the interconnection site. It's not replacing any long-range transmission with superconducting wire. You can see a diagram in the lower left of this article: http://www.tresamigasllc.com/docs/HTS-Cable-TA-Energy-Industry-Times-Nov-2010.pdf http://www.tresamigasllc.com/docs/HTS-Cable-TA-Energy-Indust... I say Tres Amigas "was" going to do this because the project seems dead. It lost a major partner in 2015, scaled back a lot, and the project site hasn't posted any updates since 2016.
