The proposed financial statements of ENEL and the consolidated financial statements for the year ended December 31, 2003, together with the respective reports of the Board of Directors, have been at the public's disposal at the registered offices of ENEL and Borsa Italiana S.p.A. since March 30, 2004.

With regard to the election of the Board of Statutory Auditors, it should be noted that the amendment of the current article 28.2 of the Bylaws proposed to the Extraordinary Meeting by the Board of Directors provides that: a) all the members of the Board of Statutory Auditors shall be elected by voting for slates; b) two regular Auditors and an alternate Auditor shall be drawn from the slate obtaining the most votes, while the remaining regular Auditor and the remaining alternate Auditor shall be drawn from the other slates; and c) the first candidate of the slate that obtains the most votes shall be entitled to the chairmanship of the Board of Statutory Auditors. If the aforesaid proposal of the Board of Directors is approved by the Extraordinary Meeting, this electoral system will already apply to the election of the Board of Statutory Auditors on the agenda of the Ordinary Meeting.

Slates of candidates for the office of Statutory Auditor must be divided into two sections: one for candidates for the office of regular Statutory Auditor and the other for candidates for the office of alternate Statutory Auditor. The first candidate in each section must be a registered auditor and must have practiced the profession of legal auditor for a period of not less than three years.

Slates of candidates for the office of Statutory Auditor may be presented by shareholders who, alone or together with other shareholders, represent at least 1% of the share capital. The presentation, filing and publication of the slates must take place according to the procedures and by the deadlines provided for by the Bylaws. You are reminded in this regard that the Self-regulation Code of listed companies suggests that, together with the slates, exhaustive written information on the personal and professional characteristics of the candidates be filed.
