[For Immediate Release]


                       HUANENG POWER INTERNATIONAL, INC.
                   Power Generation Increases 25.7% in 2004

(Beijing, China, January 10, 2005) Huaneng Power International, Inc. (the
"Company") [NYSE: HNP; HKEx: 902; SSE: 600011] today announced its results of
power generation in 2004.

 Based on preliminary statistics, as of December 31, 2004, the Company's total
power generation based on a consolidated basis for the year was 114.28 billion
kWh, an increase of 25.7% over the same period last year. The power generation
of Yushe Power Plant, Jining Power Plant, Fuzhou Power Plant, Dalian Power
Plant and Jinggangshan Power Plant increased significantly.

The increase in 2004 power generation of the Company was mainly attributed to
the following factors:


1.    Power generation of the Company's power plants increased in pace with
      the increase in power demand and power consumption in the regions where
      the Company's power plants operated owing to the economic growth in such
      areas;

2.    The Company's power generation increased significantly owing to
      half-year power generation contributed by Yingkou Power Plant,
      Jinggangshan Power Plant, Yueyang Power Plant and Luohuang Power Plant
      which were acquired by the Company in the first half of 2004;

3.    The full-year production of two generating units at Jining Power Plant
      which were commenced operation in 2003 has enhanced the Company's
      generation capacity and the newly operated generating units at Yushe
      Power Plant Phase II and Qinbei Power Plant have also contributed to the
      increase of the Company's power generation;

4.    The effective arrangement of maintenance programs has improved the
      availability of the Company's generating units; and

5.    Improved reliability of the Company's generating units through technical
      innovation has assured growth in the Company's power generation.
