American Superconductor (AMSC) is an American energy technologies company headquartered in Ayer, Massachusetts. The firm specializes in using superconductors for the development of diverse power systems, including but not limited to superconducting wire.[3] Moreover, AMSC employs superconductors in the construction of ship protection systems.[4] The company has a subsidiary, AMSC Windtec, located in Klagenfurt, Austria.

Projects

Detroit Edison Project

American Superconductor installed a test of a superconducting electric power transmission power cable in the Detroit Edison Frisbee substation in 2001.[5][6][7]

Holbrook Superconductor Project

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 high-temperature superconductor wire manufactured by American Superconductor, installed underground and chilled to superconducting temperatures with liquid nitrogen.[8]

Tres Amigas Project

American Superconductor was chosen as a supplier for the Tres Amigas Project, the United States' first renewable energy market hub.[9] 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. power grids (the Eastern Interconnection, the Western Interconnection and the Texas Interconnection). Unlike traditional powerlines, it will transfer power as DC instead of AC current. It will be located in Clovis, New Mexico.

Korea's LS Cable

AMSC will sell three million meters of wire to allow LS Cable to build 10–15 miles of superconducting cabling for the grid. This represents an order of magnitude increase over the size of the current largest installation, at Long Island Power.[10]

HTS rotors

AMSC has demonstrated a 36.5 MW (49,000 horsepower) high-temperature superconductor (HTS) electric motor for the United States Navy, and is developing a similar 10 megawatt wind turbine generator through its wholly owned Austria-based subsidiary AMSC Windtec. This would be one of the world's most powerful turbines. It operates at 30–40 kelvins, and the cooling system uses 40 kW.[11]

2009 government stimulus

In 2009, the Department of Energy announced that they would provide $4.8M to AMSC for further development of superconducting electrical cables.[3]

Sinovel controversy

In early 2011, a Serbian employee of American Superconductor sold the company's proprietary wind turbine control software to the company's largest customer, China based Sinovel. Sinovel promptly ended its payments to American Superconductor, causing the company to lose 84% of its market cap. The employee was bribed for only $20,500, and later pleaded guilty to bribery charges.[12]
