Beijing, the PRC
11 November 2011

Notes:

1.  As a result of the postponement of the EGM, the period of closure of the 
    register of members of the Company for determining the entitlement of H shares 
    shareholders to attend the EGM will be extended, details of which please refer 
    to the Announcement.

    Save as the re-scheduled time for the EGM, the extended book closure period, the
    newly-added resolutions, the revised resolution and other information as set out
    in this Supplemental Notice of 2011 Fourth Extraordinary General Meeting, other 
    matters in relation to the EGM as set out in the EGM Notice remain unchanged. 
    Unless otherwise defined, capitalized terms used in this supplemental notice 
    shall have the same meanings as defined in the circular of the Company dated 1 
    November 2011 (the "Circular").

2.  To ensure the smooth progress and the timely repayment of due loans of the 
    Duolun Coal Chemical Project, the Board proposes to the EGM to consider and 
    approve the provision of an entrusted loan of not exceeding RMB2 billion to 
    Datang Inner Mongolia Duolun Coal Chemical Co., Ltd. ("Duolun Coal Chemical 
    Company") by the Company or Datang Energy and Chemical Co., Ltd. ("Energy and 
    Chemical Company"), the Company's wholly-owned subsidiary, through CCB Diao Yu 
    Tai Branch; and the entrusted loan shall be repaid after other financings for 
    Duolun Coal Chemical Company are in place. In this regard, the Company entered 
    into the Framework Entrusted Loan Agreement with Energy and Chemical Company, 
    CCB Diao Yu Tai Branch and Duolun Coal Chemical Company on 24 October 2011, 
    details of which please refer to the Circular of the Company.

    As Energy and Chemical Company holds 60% equity interests in Duolun Coal 
    Chemical Company and CDC, the controlling shareholder of the Company, holds 40% 
    equity interests in Duolun Coal Chemical Company, Duolun Coal Chemical Company 
    is a connected person of the Company pursuant to the Rules Governing the Listing
    of Securities on The Stock Exchange of Hong Kong Limited (the "Listing Rules"), 
    therefore the transaction constitutes a connected transaction of the Company and
    will be tabled to the EGM for shareholders' consideration and approval. CDC, a 
    connected shareholder, and its associates, are required to abstain from voting 
    at this resolution at the EGM.

3.  In order to ensure normal progression on project construction, production and 
    operation of the following subsidiaries, the Company intends to provide 
    guarantees to the following subsidiaries:

    (1)  To provide guarantees in proportion to the Company's shareholding for an 
         amount of not exceeding RMB210 million for the financing of Hebei Datang 
         International Wangtan Power Generation Company Limited, in which the 
         Company holds 70% equity interests;

    (2)  To provide guarantees in proportion to the Company's shareholding for an 
         amount of not exceeding RMB409 million for the financing of Sichuan Jinkang
         Electricity Development Company Limited, in which the Company holds 54.44% 
         equity interests;

    (3)  To provide guarantees in full amount of not exceeding RMB600 million for 
         the financing of Fujian Datang International Ningde Power Generation 
         Company Limited, in which the Company holds 51% equity interests.

    Since the asset-liability ratios of the aforesaid subsidiaries are all over 70%,
    the provisions of guarantees are required to be tabled to the EGM for 
    shareholders' consideration and approval pursuant to the Listing Rules of the 
    Shanghai Stock Exchange and the "Articles of Association of Datang International
    Power Generation Co., Ltd.". Please refer to the announcement of the Company 
    dated 2 November 2011 for details.
