To the Shareholders


Dear Sir or Madam,

                            BONUS ISSUE OF H SHARES

Bonus Issue of Shares

According to the announcement of the Company dated 30 March 2007, the Board
resolved to propose to the AGM the Bonus Issue, on the basis of 10 bonus Shares
to be issued for every 10 Shares held by the Shareholders on the Record Date,
under the share capital expansion by utilising the capital reserve fund. This
proposal was approved by the Shareholders at the AGM. Based on the Company's
total share capital of 5,844,880,580 Shares on the Record Date, 5,844,880,580
bonus Shares will be issued by the Company, of which 1,612,700,580 Shares are
Bonus H Shares and 4,232,180,000 Shares are Bonus A Shares. The total share
capital of the Company will increase to 11,689,761,160 Shares upon completion of
the Bonus Issue. The Bonus H Shares shall rank pari passu in all respects with
the existing H Shares.


Conditions of the Bonus Issue

The Bonus Issue is conditional upon obtaining the approval of the Shareholders
at the AGM. The Company has obtained the approval from its Shareholders in
respect of the Bonus Issue by way of special resolution in the AGM on 29 June
2007. The Bonus Issue in respect of the Bonus A Shares has become unconditional.

The Bonus Issue in respect of Bonus H Shares is conditional upon the Listing
Committee of the Hong Kong Stock Exchange's granting listing of, and
permission to deal in, the Bonus H Shares.


Reasons for the Bonus Issue

The Bonus Issue will reciprocate the Shareholders' long term support and
concern, and expand the share capital base of the Company.


Closure of Register of H Shares Members

According to the announcement of the Company dated 29 June 2007, the register of
H Shares members of the Company was closed from 19 July 2007 to 24 July 2007
(both days inclusive) during which period no transfer of H Shares was effected.
Holders of H Shares of the Company whose names appear on the register of H
Shares members of the Company as at the close of business at 4:30 p.m. on 18
July 2007 were entitled to the dividends of the Company for the year ended 31
December 2006 and the Bonus Issue.


Listing and Dealings

The H Shares of the Company are listed on the Hong Kong Stock Exchange and The
London Stock Exchange while the Company's A Shares are listed on the Shanghai
Stock Exchange. The Company had issued US Dollar convertible bonds of US$153.8
million, which are convertible into H Shares, and are listed on the Luxembourg
Stock Exchange.

Application has been made to the Listing Committee of the Hong Kong Stock
Exchange for listing of, and permission to deal in, the Bonus H Shares. Subject
to the satisfaction of the condition as set out in this circular, the Bonus H
Shares will be accepted as eligible securities by HKSCC for deposit, clearance
and settlement in CCASS. All necessary arrangements will be made for the Bonus H
Shares to be admitted into CCASS. All activities under CCASS are subject to the
General Rules of CCASS and CCASS Operational Procedures in effect from time to
time.

Upon the Bonus Issue becoming unconditional, it is expected that certificates
for the Bonus H Shares will be posted to those entitled thereto at their own
risk on or before 30 July 2007. In the case of joint shareholdings, the
certificates for the Bonus H Shares will be posted to the address of the first
named member on the register of members of the Company in respect of such joint
holding.

Dealings in the Bonus H Shares, which are expected to commence on 1 August 2007
will be subject to Hong Kong stamp duty.


Warning of Risks of Dealings in Shares

Shareholders of H Shares should note that the Shares have been dealt with on an
ex-entitlement basis commencing from 17 July 2007. The Bonus Issue is
conditional upon the condition set out in this circular under heading of
'Conditions of the Bonus Issue'. Any person dealing in the Shares on an ex-
entitlement basis up to such condition is fulfilled will accordingly bear the
risk that the Bonus Issue may not become unconditional and may not proceed. Any
person contemplating selling or purchasing Shares during such period who is in
any doubt about his/her/its position is recommended to consult his/her/its own
professional adviser.


                                                Yours faithfully,
                                               For and on behalf of
                                 Datang International Power Generation Co., Ltd.
