                       HUANENG POWER INTERNATIONAL, INC.
                  Announces Annual Operating Results for 2003

              Net Profit Increases by 38.50% to RMB5.430 billion

(Beijing, China, March 16, 2004) Huaneng Power International, Inc. (the
"Company") [NYSE: HNP; HKEx: 902; SSE: 600011] today announced its audited
operating results under International Financial Reporting Standards for the
year ended December 31, 2003. The Company's net operating revenues for 2003
were RMB23.388 billion (approximately US$2.826 billion based on the exchange
rate of US$1 to RMB8.2767 on December 31, 2003), a 26.60% increase over 2002.
Net profit was RMB5.430 billion (approximately US$656 million), a 38.50%
increase over 2002. Basic earnings per share was RMB0.90 (approximately
US$0.11). Basic earnings per American Depository Share (ADS) was RMB36
(approximately US$4.35). The Board of Directors of the Company was very
satisfied with the operating results for last year.

The Company's Board of Directors proposed that the Company pay dividend
consisting of both cash and the Company's stock to its shareholders. Under the
proposed dividend plan, which is subject to the approval by the Company's
shareholders at the annual general meeting of the Company, every 10 shares of
the issued and outstanding common stock of the Company will be entitled to
receiving RMB5.0 in cash and 10 shares of the Company's common stock.

In 2003, the Company strengthened equipment management and effective cost
control, thereby achieving safe and stable operation of the Company's power
plants. The Company has contributed to meeting power consumption demand,
ensuring safe power generation and supporting economic development.

In 2003, the Company's total power generation based on a consolidated basis
was 90.91 billion kWh (which includes the power generation of Xindian Power
Plant and Taicang Power Plant from November to December), an increase of
27.30% over 2002. The average availability factor of the power plants of the
Company was 92.15% and the average capacity factor was 68.06%. Average coal
consumption rates for power sold and for power generated were 335.12 gram/kWh
and 318.23 gram/kWh, respectively, while the average house consumption rate
was 4.76%. The unit fuel cost for output stayed within its estimated range as
set in the beginning of the year and only increased by 2.28%. The Company's
techno-economic indices continued to score the industry's bests in the PRC.





Huaneng Power Int'l, Inc.
Announces Annual Operating Results for 2003...P.2

The steady growth in the operating results of the Company was, on the one
hand, attributable to the increased power demand driven by the rapid and
steady economic growth of the country. On the other hand, the Company's power
project development and acquisitions also made significant contribution to the
remarkable growth of the Company's operating results for year 2003.

The Company made new breakthroughs in asset acquisitions in 2003. After
acquiring 25% equity interest in Shenzhen Energy Group in the beginning of the
year, the Company also acquired equity interest and assets of Qinbei Power
Plant, Yushe Power Plant and Xindian Power Plant from China Huaneng Group.
These two acquisitions increased the generation capacity of the Company on an
equity basis by 1,231MW, and the generation capacity under construction on an
equity basis by 1,020MW. The acquisitions made contribution to the growth of
the Company's annual operating results.

The Company is making good and smooth progress on the preliminary work of its
power plant constructions and planned projects. Two generating units with
cycled fluidized bed combustion boilers at Jining Power Plant came into
commercial operation in July and August 2003 respectively. Construction of two
330MW coal-fired generating units at Huaiyin Power Plant Phase II and one
600MW coal-fired generating unit at Shantou Power Plant Phase II have
commenced. The feasibility study report on constructing China's first two
1,000MW ultra-supercritical coal-fired generating units at Yuhuan Power Plant
Phase I has been approved by the State Council. In addition, project proposals
in relation to the construction of Taicang Power Plant Phase II (2x600MW
coal-fired generating units), Shanghai Gas-fired Power Plant (3 x 300MW-class
Combined-Cycle-Gas-Turbine generating units) and Jinling Gas-fired Power Plant
(3 x 300MW-class Combined-Cycle-Gas-Turbine generating units) have been
approved by the State Council. The Company will actively push forward the
progress of these projects based on sound commercial principles.

In addition, in considering rising oil prices and the need of reducing
operating costs, the Company shut down two 100MW oil-fired generating units at
Xindian Power Plant Phase I at the end of 2003. These two units have been in
operation for 30 years and made an operating loss in the current period. Thus
the generation capacity of Xindian Power Plant on an equity basis has
decreased from 650MW to 450MW.

Year 2004 is a year full of challenges and opportunities. The Company needs to
ensure safe production and sufficient supply of coal as well as to complete
the construction projects on schedule. We expect to continue to face pressures
from rising fuel prices, increased environmental related expenses and
increasing market competition. However, the Company has full confidence and
strength to seize opportunities and overcome challenges, and will endeavor to
fulfill the following objectives in 2004:





Huaneng Power Int'l, Inc.
Announces Annual Operating Results for 2003...P.3

1.    To ensure safe and operating stability of the Company's power plants,
      and achievement of their annual generation plans; and on this basis, to
      analyze and formulate effective market strategies with respect to power
      market and power pooling, so as to enlarge our power market shares;

2.    To undertake stringent control of operating costs, in particular with
      respect to fuel costs and construction costs;

3.    To actively develop the proposed projects and push forward the work for
      the power plants under construction, with a view to expanding the
      Company's operating scale and enhancing its business strengths; and

4.    To actively seek new opportunities for asset acquisitions in order to
      assure continuous growth of the Company's profits and shareholder value.

The Company develops, constructs, operates and manages large thermal power
plants in China nationwide, with a total generation capacity of 15,736MW on an
equity basis. The Company wholly owns 14 power plants, and has controlling
interests in five power plants and minority interests in three power
companies. Today, the Company is one of the largest independent power
producers in China.
