Special Notices

The Company and all members of the board of directors warrant the truthfulness,
accuracy and completeness of the announcement, and jointly accept the
responsibility for any false representations or misleading statements contained
in, or material omissions from, this announcement.

This announcement is made pursuant to Rule 13.09(2) of the Rules Governing the
Listing of Securities on The Stock Exchange of Hong Kong Limited.

Datang International Power Generation Co., Ltd. (the 'Company') would like to
announce that based on the Company's preliminary statistics, as of 30 June
2007, total power generation of the Company and its subsidiaries (the 'Group')
during the first half of 2007 amounted to 56.042 billion kWh, an increase of
35.54% when compared to the corresponding period of the previous year. The 
Group's total on-grid power generation was 52.812 billion kWh, an increase of
35.79% when compared to the corresponding period of the previous year.

The increase in the Group's power generation for the first half of 2007 as
compared with that of the previous year was mainly attributable to the following
reasons:

1.     Increased capacity of operating generation units: Comparing the first
half of 2007 to the corresponding period of 2006, a number of the Company's
subsidiaries have witnessed commencement of operation of new generation units
with an aggregate capacity of 4,020 MW, thereby substantially increasing the
overall power generation capacity of the Company. Such subsidiaries include
Zhejiang Datang Wushashan Power Generation Company Limited ('Wushashan Power'),
Guangdong Datang International Chaozhou Power Generation Company Limited
('Chaozhou Power'); Fujian Datang International Ningde Power Generation Company
Limited ('Ningde Power'); Yunnan Datang International Honghe Power Generation
Company Limited ('Honghe Power'), and the Yayangshan Hydropower Project of
Yunnan Datang International Lixianjiang Hydropower Development Company Limited
('Lixianjiang Hydropower').

2.     Increased demand in service areas: For the first half of 2007, the power
demand within the service areas of the Company - the Beijing-Tianjin-Tangshan
Power Grid, the Shanxi Power Grid, the Gansu Power Grid, the Yunnan Power Grid,
the Zhejiang Power Grid and the Guangdong Power Grid - continued to maintain
stable and rapid growth.

3.     Improvement in operating reliability of generation units: For the first
half of 2007, the Company achieved an equivalent availability factor of 93.88%,
representing an increase of 1.13 percentage points when compared to 92.75% as in
the corresponding period of 2006.

4.     The power generation obstruction problem at Hebei Datang International
Wangtan Power Generation Company Limited ('Wangtan Power') was resolved and its
generation units are now operating in full capacity. The utilisation rate of the
Company's generation units increased substantially in the first half of 2007
as compared to the corresponding period of 2006.
