WESTBOROUGH, Mass.--(BUSINESS WIRE)

American Superconductor Corporation (Nasdaq:AMSC) announced today that, in response to a high demand, it has posted the slide presentation made by its chief executive officer, Greg Yurek, at the GilderGroup's Powercosm(TM) meeting on December 10, 2000 in New Orleans. A direct link to this slide show can be found on the company's home page at http://www.amsuper.com.

Highlights of the presentation include:

- An update on the company's industry-leading products, which leverage the
company's strengths in high temperature superconductivity (HTS) and power
electronics. Yurek emphasized that the company's current and future products
are expected to provide substantial benefits in the production, delivery and
use of power on today's highly stressed power infrastructure. He commented on
the award of a follow-on contract from the U.S. Navy for the design and
development of HTS motors for ship propulsion, and he reported on the company's
progress in development of its second-generation HTS wires.

- A progress report on the company's Detroit Edison project with its long-time
strategic alliance partner, Pirelli Cables and Systems. Yurek noted that
Pirelli had recently announced the completion of the 2,400 Amp "cable
conductor" using American Superconductor's HTS wire. This milestone marks
significant progress toward meeting the goal of installing the cable system in
downtown Detroit in the first quarter of 2001 and taking it on line to serve
14,000 power customers in the second quarter of 2001. This will be the first
HTS power cable to be installed in a live utility grid. To learn more about the
Detroit project, see http://www.amsuper.com/detroi t.

- A detailed discussion of the company's power electronics business, including
the company's line of programmable high capacity power converter modules. These
products are used in the company's Superconducting Magnetic Energy Storage
(SMES) systems, and are targeted for use in a wide-array of additional power
applications, including distributed generation.

- An overview of the company's commanding intellectual property position. Yurek
noted that the company currently has over 250 U.S. patents, patent applications
and licenses in the area of HTS wires and applications, including both first-
and second-generation wire technology, SMES and power electronics. It has
nearly the same amount outside the U.S.
