About Us

AMSC offers an array of proprietary technologies and solutions spanning the electric power infrastructure – from generation to delivery to end use. The company is a leader in alternative energy, providing proven, megawatt-scale wind turbine designs and electrical control systems. The company also offers a host of Smart Grid technologies for power grid operators that enhance the reliability, efficiency and capacity of the grid, and seamlessly integrate renewable energy sources into the power infrastructure. These include superconductor power cable systems, grid-level surge protectors and power electronics-based voltage stabilization systems. AMSC ’s technologies are protected by a broad and deep intellectual property portfolio consisting of hundreds of patents and licenses worldwide.

The demand for clean and renewable sources of electricity, such as wind energy, and the demand for modernized power grid infrastructure are being driven globally by a variety of factors. These factors include increasing electricity usage, power grid capacity constraints, fossil fuel price volatility, and harmful levels of pollution and greenhouse gases. In addition, our growing digital-based economy demands better power reliability and quality. Concerns about these factors have led to increased spending by corporations and supportive government regulations and initiatives on local, state, national and global levels, including renewable portfolio standards, tax incentives and international treaties.

We conduct our operations through two business units:

AMSC Power Systems: Produces a broad range of products to increase electrical grid capacity and reliability; supplies electrical systems used in wind turbines; sells power electronic products that regulate wind farm voltage to enable their interconnection to the power grid; licenses proprietary wind energy system designs to manufacturers of such systems; and provides consulting services to the wind industry.
AMSC Superconductors: Focuses on the manufacturing of HTS wire and coils; the design and development of HTS products such as power cables, fault current limiters and motors; and the management of large-scale HTS projects such as HTS power cable system design, manufacturing and installation.

AMSC is the world's principal vendor of high temperature superconductor wire and large rotating superconductor machinery and a world-leading supplier of dynamic reactive power grid stabilization products. AMSC's HTS wire and power electronic converters are at the core of a broad range of new electricity transmission and distribution, transportation and industrial processing applications. Our products are supported by hundreds of patents and licenses covering technologies fundamental to Revolutionizing the Way the World Uses Electricity™.

Founded in 1987, the company is headquartered in Devens, Massachusetts.
