American Superconductor is an American energy technologies company based in Devens, Massachusetts specializing in the design and manufacture of power systems and superconducting wire. It owns AMSC Windtech in Klagenfurt, Austria. American Superconductor installed a test of a superconducting electric power transmission power cable in the Detroit Edison Frisbee substation in 2001. The world's first production superconducting transmission power cable, the Holbrook Superconductor Project, was commissioned in late June 2008. The suburban Long Island electrical substation is fed by about 600... meters of superconductor wire manufactured by American Superconductor, installed underground and chilled with liquid nitrogen to minimize power loss in the transmission lines. American Superconductor was chosen as a supplier for the Tres Amigas Project, the United States’ first renewable energy market hub. The Tres Amigas renewable energy market hub will be a multi-mile, triangular electricity pathway of Superconductor Electricity Pipelines capable of transferring and balancing many gigawatts of power between three U.S.
