(1) Caja Madrid is a savings bank (“Caja de Ahorros”) formed under the laws of the Kingdom of Spain.

This Amendment No. 5 (“Amendment No. 5”) amends the Schedule 13D filed by Caja de Ahorros y Monte de Piedad de Madrid, Caja Madrid, a corporation organized under the laws of the Kingdom of Spain (“Caja Madrid”), with the Securities and Exchange Commission (the “SEC”) on October 11, 2005, as previously amended by Amendment No. 1 thereto filed with the SEC on February 14, 2007, by Amendment No. 2 thereto filed with the SEC on March 28, 2007, by Amendment No. 3 thereto filed with the SEC on April 23, 2007, and by Amendment No. 4 thereto filed with the SEC on September 18, 2007 (together, the “Schedule 13D”). This filing relates to the Ordinary Shares, nominal value €1.20 each (the “Ordinary Shares”), and American Depositary Shares, each representing the right to receive one Ordinary Share (“ADSs”), of Endesa, S.A., a corporation organized under the laws of the Kingdom of Spain (the “Issuer” or “Endesa”). The principal executive offices of Endesa are located at Ribera del Loira, 60, 28042 Madrid, Spain.

Item 4. Purpose of Transaction

Item 4 is hereby amended to add the following supplemental information:

Acciona, S.A. (“Acciona”), a Spanish corporation, and Enel Energy Europe S.r.L. (“EEE” and together with Acciona, the “Offerors”), an Italian limited liability company and a wholly owned subsidiary of ENEL S.p.A. (“ENEL”), an Italian corporation, have offered to acquire all of the outstanding Ordinary Shares and ADSs of Endesa (the “Offer”).

As described under Item 5 below, as of October 1, 2007, the deadline for acceptance of the Offer, Caja Madrid has tendered to the Offerors pursuant to the Offer all of the 105,076,259 Ordinary Shares of which it was the beneficial owner as of that date.

Item 5. Interest in Securities of the Issuer

Item 5 is hereby amended and restated as follows:

As of October 1, 2007, the deadline for acceptance of the Offer, Caja Madrid has tendered to the Offerors pursuant to the Offer all of the 105,076,259 Ordinary Shares of which it was the beneficial owner as of that date. On October 5, 2007, the Spanish Comisión Nacional del Mercado de Valores informed the Offerors that a sufficient number of Ordinary Shares and ADSs of Endesa had been tendered into the Offer to satisfy the minimum tender condition under the Offer, thereby enabling the successful completion of the Offer. Accordingly, Caja Madrid no longer beneficially owns any Ordinary Shares.

Caja Madrid acts as a nominee on behalf of certain of its clients that beneficially own Ordinary Shares, and in that connection from time to time receives instructions from such clients with respect to the voting of such Ordinary Shares. Caja Madrid may not vote Ordinary Shares held by its clients unless directed by the respective client, and as a result Caja Madrid is not deemed to be the beneficial owner of such Ordinary Shares. Accordingly, such Ordinary Shares are not included on this Schedule 13D.

SIGNATURE

After reasonable inquiry and to the best of the undersigned’s knowledge and belief, each of the undersigned certifies that the information set forth in this statement is true, complete, and correct.
