          This Amendment No. 6 is the final amendment to the Statement on
Schedule 13D initially filed on June 7, 1999, with the Securities and Exchange
Commission (the "SEC") by RWE Aktiengesellschaft, a corporation organized
under the laws of the Federal Republic of Germany ("RWE"), as previously
amended by Amendment No. 1 filed with the SEC by RWE on September 5, 2001;
Amendment No. 2 filed with the SEC by RWE on June 2, 2003; Amendment No. 3
filed with the SEC by RWE on September 19, 2003; Amendment No. 4 filed with
the SEC by RWE on October 3, 2003; and Amendment No. 5 filed with the SEC by
RWE on February 13, 2004 (such Schedule 13D as so amended and restated, the
"Schedule 13D"), which Schedule 13D relates to the common stock, par value
$.01 per share (the "Common Stock"), of CONSOL Energy Inc. (the "Issuer").
Unless otherwise defined herein, capitalized terms used herein have the
respective meanings ascribed thereto in the Schedule 13D.

Item 5.  Interest in Securities of the Issuer

          (e) On February 20, 2004, RWE Power Aktiengesellschaft, through
which RWE beneficially owned all of its Common Stock of the Issuer, closed on
the sale of all of its 16,622,932 shares of Common Stock of the Issuer in a
private placement transaction pursuant to the agreement related thereto
reported on by Amendment No. 5 to the Schedule 13D, and RWE ceased to be the
beneficial owner of any shares of Common Stock of the Issuer. This is the
final amendment to the Schedule 13D, reflecting that as of February 20, 2004,
RWE does not beneficially own any Common Stock of the Issuer.





                                                                             4


                                   Signature

          After reasonable inquiry and to the best of my knowledge and belief,
I certify that the information set forth in this statement is true, complete
and correct.
