[For Immediate Release]


                       HUANENG POWER INTERNATIONAL, INC.
               First Quarters Power Generation Increases 24.04%

(Beijing, China, April 8, 2004) Huaneng Power International, Inc. (the
Company) [NYSE: HNP; HKEx: 902; SSE: 600011] today announced its power
generation for the first quarter of 2004.

Based on preliminary statistics, as of March 31, 2004, the Companys total
power generation based on a consolidated basis for the first quarter of 2004
was 24.56 billion kWh, an increase of 24.04% over the same period last year on
the same basis. Among the power plants of the Company, Fuzhou Power Plant,
Jining Power Plant, Nantong Power Plant and Shanghai Shidongkou Second Power
Plant have achieved relatively high increase rates in power generation.

The increase in power generation of the Companys power plants was mainly
attributable to the following reasons:

1.       Stable generation capacity of the newly operated generating units 5
         and 6 of Jining Power Plant (2 x 135MW);

2.       Increase in power generation contributed by Xindian Power Plant and
         Yushe Power Plant, which were acquired in 2003;

3.       Significant increase in power consumption in the regions where the
         Companys power plants operated, thereby providing the conditions for
         growth in the Companys power generation;

4.       Effective arrangement of maintenance programs during the Chinese New
         Year and improved reliability of the Companys generating units,
         together with stable coal supply, thereby assuring the growth in the
         Companys power generation;

5.       The Companys enhanced sales and marketing efforts and its endeavors
         in developing the power market, which have led to enlarged market
         shares.
