                       Announcement on Power Generation
                     for the First Three Quarters of 2003


Huaneng Power International, Inc. (the  "Company") announced its power
generation for the first three quarters of 2003.


Based on the preliminary statistics, as of 30th September, 2003, the Company's
total power generation based on the consolidated financial statement for the
first three quarters was 66.05 billion kWh, representing an increase of 31.3%
over the same period of last year.


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


1.       significant  increase in power  demand and power  consumption  in the
         regions  where the  Company's  power  plants  operate due to a steady
         growth of the national economy;


2.       increase in residential  power consumption due to hot weather in many
         regions during the spring and summer of this year;


3.       increase  in  generation  as a  result  of  stable  operation  of the
         generating units 5 and 6 of Dezhou Power Plant and the newly operated
         generating units 5 and 6 of Jining Power Plant;


4.       the improved availability and reliability of the Company's generating
         units through  technical  innovation,  thereby assuring growth in the
         Company's power generation.


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