requirement. Pursuant to Rule 14.44 of the Listing Rules, such Shareholders' approval requirement can be satisfied by

approximately 35.43%, 13.01%, 13.01% and 10.84%, respectively, of the issued share capital of the Company.


Each of (a) China Datang Corporation (or its predecessor, North China Power Group Company, which transferred its entire
shareholding in the Company to China Datang Corporation by way of administrative allocation on 9 April 2003 without any
change of ultimate beneficial ownership since both China Datang Corporation and North China Power Group Company were
wholly-owned by the PRC government), (b) Beijing Energy Investment (Group) Company (or its predecessor, Beijing
International Power Development and Investment Company, which transferred its entire shareholding in the Company to
Beijing Energy Investment (Group) Company by way of administrative allocation in December 2004 without any change of
ultimate beneficial ownership since both Beijing International Power Development and Investment Company and Beijing
Energy Investment (Group) Company were wholly-owned by the PRC government),  and (c) Hebei Construction Investment
Company has been Shareholder since the incorporation of the Company (formerly known as Beijing Datang Power Generation
Co., Ltd.) in December 1994. Tianjin Jinneng Investment Company has been Shareholder since 1999.

in the event that any of them was required to abstain from voting under the Listing Rules) on each of the Shareholders'

the voting by way of written Shareholders' approval, where applicable).


In view of the above, China Datang Corporation, Beijing Energy Investment (Group) Company, Hebei Construction
Investment Company and Tianjin Jinneng Investment Company could be viewed as a closely allied group of Shareholders for
the purpose of approving the Investment Agreement.


Since no Shareholder is required to abstain from voting if the Company were to convene a general meeting to approve the

China Datang Corporation, Beijing Energy Investment (Group) Company, Hebei Construction Investment Company and Tianjin
Jinneng Investment Company, who together hold an aggregate of 3,732,180,000 Domestic Shares representing approximately
72.29% of the issued share capital of the Company, the shareholders' approval requirement under Rule 14.40 of the
Listing Rules has therefore been satisfied by means of written Shareholders' approval pursuant to Rule 14.44 of the
Listing Rules and a general meeting of the Company to approve the Investment Agreement will not be held.
