                       HUANENG POWER INTERNATIONAL, INC.
                  Announces 2003 First Three Quarters Results

                Net Profit Increases 30.52% to RMB 3.971 Billion

(Beijing,  China,  October 21, 2003)  Huaneng  Power  International,  Inc. (the
"Company")  [NYSE:  HNP; HKEx: 902; SSE:  600011] today announced its unaudited
results for the nine months ended September 30, 2003.

Under the PRC Accounting  Standards,  for the first three quarters of 2003, the
Company realised operating revenues of RMB 16.830 billion and net profit of RMB
3.971 billion, representing increases of 27.11% and 30.52%, respectively,  over
the same  period  last  year.  For the third  quarter  of 2003,  the  operating
revenues,  net  profit and  earnings  per share of the  Company  were RMB 6.211
billion, RMB 1.615 billion and RMB0.27, respectively, representing increases of
17.75%,  32.23% and 35.00%,  respectively,  over the same period last year. The
increase in operating  revenues of the Company for the first three  quarters of
2003 was due to substantial increase in power generation of the Company's power
plants, which was mainly attributable to the following reasons:

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

2.    Residential  power  consumption  increased  due to hot  weather  in  many
      regions during spring and summer this year;

3.    Increase in power generating  capacity as a result of stable operation of
      the  generating  units 5 and 6 of  Dezhou  Power  Plant  which  commenced
      operations  in 2002 and the newly  operated  generating  units 5 and 6 of
      Jining Power Plant;

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

The Board of Directors of the Company was satisfied with the operating  results
obtained in the first three quarters of 2003.


                                                                          .../2
