This project represents several firsts in HTS cable installation: 3.5 times the length of any previously installed HTS cable; the installation will be in a standard utility underground right-of-way (other installations have been within an industrial site or a substation); it addresses future commercialization by including a 30-m (98-ft) YBCO cable section with potential for improved price/performance characteristics; and it demonstrates an underground cable-to-cable joint, which enables long cable runs.
