                                             SUPPLEMENTAL AGREEMENT TO THE

                                        DISCLOSEABLE AND CONNECTED TRANSACTION



Reference is made to the announcement published by Datang International Power Generation Company Limited (the
'Company') dated 10 January 2007 (the 'Announcement') and the circular issued by the Company dated 31 January 2007 (the
'Circular'). Unless otherwise defined, capitalised terms used herein shall have the same meanings as defined in the
Announcement and the Circular.



The Board announces that on 15 February 2007, the Company entered into a supplemental agreement to the Investment
Agreement (the 'Supplemental Agreement') with BEIG, CDGC, MDHN and (Chinese Words) (Beijing Jingneng International
Energy Company Limited) ('BIEC'). Under the Supplemental Agreement, BIEC shall supersede BEIG as the entity of the
Investment Agreement and assume all rights, obligations and liabilities of BEIG in the Investment Agreement. The
Supplemental Agreement shall form an inalienable part of the Investment Agreement and save as expressly provided in the
Supplemental Agreement, all the provisions in the Investment Agreement shall remain in full force and effect. Having
made all reasonable enquiries, the Directors confirm that to the best of their knowledge and belief, the sole purpose
of entering into the Supplemental Agreement is to enable BEIG to improve its internal management. Therefore, it is
decided that BIEC shall supersede BEIG as the entity of the Investment Agreement to invest in the Tuoketuo Power Plant
Project.



The Supplemental Agreement will become effective when the respective parties have obtained approvals from their
authorities for entering into the Supplemental Agreement. As at the date of this announcement, the Company still has to
submit the Investment Agreement to its 2007 first EGM on 30 March 2007 for consideration and approval.



Shareholders having material interests in the transaction and their respective Associates will abstain from voting.
Since BEIG is the ultimate beneficial owner of BIEC and is a shareholder of the Company holding approximately 11.86% of
its issued share capital, BEIG and its Associates will abstain from voting in accordance with the Listing Rules.
