[For Immediate Release]

                       HUANENG POWER INTERNATIONAL, INC.
                        Announces 2003 Interim Results

                Net Profit Increases 28.58% to RMB2,285 Million

(Beijing, China, August 6, 2003) Huaneng Power International, Inc. (the
"Company") [NYSE: HNP; HKEx: 902; SSE: 600011] today announced its unaudited
operating results for the six months period ended June 30, 2003.


Consolidated net profit of the Company and its subsidiary for the first half
of 2003 was RMB 2,285 million (equivalent to US$276 million), representing an
increase of 28.58% compared to the same period last year. Earnings per share
was RMB0.38 or RMB15.20 (equivalent to US$1.84) for each American Depositary
Share. The board of directors does not recommend any interim dividends for
year 2003.

The increase in profit is due to power generation increase of the Company's
power plants, as well as the Company's effective cost control measures. The
Company's average unit cost for power sold for the first half of 2003 was
decreased by 2.19% compared to the same period last year. The board of
directors of the Company is satisfied with the above operating results.

With the joint efforts made by the management and all the staff, the Company
achieved satisfactory results in all aspects in the first half of this year:

1.    The Company's total power generation based on a consolidation basis for
      the first half of the year was 41.079 billion kWh, an increase of 39.67%
      over the same period last year.

2.    The Company made breakthrough in acquiring power assets. i) The Company
      entered into an agreement with Shenzhen Energy Group Co., Ltd. ("SEG")
      and Shenzhen Investment Holding Corporation to acquire a 25% interest of
      the enlarged share capital of SEG. The transaction was completed and it
      enlarged the Company's market share in Guangdong Province, in particular
      Shenzhen Municipality, an area with rapid economic growth and
      substantial power demand. ii) The Company entered into a transfer
      agreement with China Huaneng Group on June 5, 2003 about transferring
      China Huaneng Group's equity interests in Henan Huaneng Qinbei Power
      Generation Limited Liability Company, Shanxi Huaneng Yushe Power Limited
      Liability Company and the entire assets and liabilities of China Huaneng
      Group Xindian Power Plant. The acquisition and the connected
      transactions ancillary thereto were approved by the extraordinary
      general meeting on July 22, 2003, now pending the approvals from the
      relevant government authorities. The Company believes that the
      acquisition will bring increase in earnings per share for the Company.

3.    In addition, i) the two environmental friendly 135 MW coal-fired
      generating units (Units 5 and 6) of Jining Power Plant expansion project
      (using Cycled Fluidized Bed Combustion Boilers) have completed their 168
      hours full-load trial run on July 11 and August 5, 2003, respectively
      and the generating unit 5 has commenced commercial operation. ii) The
      two gas-fired generation projects in Shanghai and Jinling and the
      expansion projects of Huaiyin Power Plant Phase II and Shantou Power
      Plant Phase II, as well as Zhejiang Yuhuan Power Plant have made
      progress on their preliminary work.

In the second half of year 2003, increasing power demand will put a lot of
pressure on the power supply, and the power tariff reform will be further
deepened. The management of the Company will continue to put optimization of
shareholders' interests as its operating objective, seizing the opportunities
and overcoming the difficulties. Accordingly, the management and all the staff
of the Company will make joint efforts to ensure the achievement of the annual
targets in terms of generation and operation as well as other aspects, and to
bring stable and growth return to all of its shareholders.

Huaneng Power International, Inc. develops, constructs, operates and manages
large thermal power plants in China nationwide, with a total generation
capacity of 14,915MW on an equity basis. The Company wholly owns 13 power
plants, and has controlling interests in three power plants and minority
interests in three power companies. Today, it is one of the largest
independent power producers in China.
