             Results of Power Generation in First Quarter of 2003

Huaneng Power International, Inc. (the "Company") announced its power
generation in the first quarter of 2003.


This announcement is issued pursuant to paragraph 2(2) of the Listing
Agreement between The Stock Exchange of Hong Kong Limited and the Company.


Based on preliminary statistics, as of 31st March 2003, the Company's total
power generation based on a consolidated basis for the first quarter of 2003
was 19.8 billion kWh, an increase of 42.86% over the same period last year on
the same basis.


The increase in power generation of the Company's power plants for the first
quarter of 2003 was mainly attributable to the following reasons:


1.    Increase in power generation was contributed by Shanghai Shidongkou
      First Power Plant, Changxing Power Plant, Huaiyin Power Plant and
      Taicang Power Plant, all of them were acquired last year;


2.    Stable generation capacity of the newly operated generating units 5 and
      6 of Dezhou Power Plant;


3.    Significant increase in power consumption in the regions where the
      Company's power plants operated;


4.    The effective arrangement of maintenance programs during the Chinese New
      Year and the improved reliability of the Company's generating units have
      assured the growth in the Company's power generation; and


5.    The Company enhanced sales and marketing efforts, as well as enlarged
      its market shares.


The power generation of each of the Company's power plants for the first
quarter of 2003 was, respectively, as follows (in billion kWh):
