AMENDMENT No. 1 TO SCHEDULE 13D

This Amendment No. 1 amends the Statement on Schedule 13D originally filed on October 8, 1999 (“Schedule 13D”), on behalf of E.D.F. Capital Investissement, S.A. (“ECI”), a corporation organized under the laws of France and a wholly-owned subsidiary of Electricité de France, S.A., a corporation organized under the laws of France (“EDF”), relating to the common stock, USD.01 par value per share (the “Common Stock”) of American Superconductor Corporation, a Delaware corporation (the “Issuer”). As indicated in Item 5(e) below, ECI has ceased to be the beneficial owner of more than 5% of the Common Stock and is no longer subject to the reporting requirements of Regulation 13D under the Act.

      Item 5.  Interest in Securities of the Issuer

No changes except the following:

(a) Amount Beneficially Owned:

        ECI beneficially owns 1,074,000 shares of Common Stock.

Percent of Class:

        Based on shares outstanding as of December 31, 2003, ECI owns 3.95% of the outstanding Common Stock.

(b) Number of shares as to which ECI has:

  (i) sole power to vote or direct the vote: 1,074,000 shares

  (ii) shared power to vote or direct the vote: None.
  (iii) sole power to dispose or to direct the disposition of: 1,074,000 shares
  (iv) shared power to dispose or to direct the disposition of: None.

(c) On February 20, 2004, ECI sold 74,000 shares of Common Stock over the NASDAQ National Market at a price of $15.0744 per share.

(e) ECI ceased to be the beneficial owner of more than 5% of the Common Stock in October 2003 after completion by the Issuer of a capital increase through a public offering of an additional 5,721,250 shares of Common Stock, in which ECI did not participate. ECI’s beneficial ownership was diluted to 4.2% as a consequence.
