[For Immediate Release]

                       HUANENG POWER INTERNATIONAL, INC.
             Announces Results for the First Three Quarters of 2005


(Beijing, China, October 18, 2005) Huaneng Power International, Inc. (the
"Company") [NYSE: HNP; HKEx: 902; SSE: 600011] today announced its unaudited
results for the nine months ended September 30, 2005.

Under the PRC Accounting Standards, for the first three quarters of 2005, the
Company realised operating revenues of RMB29.126 billion, representing an
increase of 35.97% over the same period last year. Net profit amounted to
RMB3.050 billion, representing a decrease of 20.97% over the same period last
year. The Company's total power generation on a consolidated basis for the
first three quarters of 2005 amounted to 110.956 billion kWh, an increase of
37.3% over the same period last year.

Compared to the same period last year, newly acquired power plants and newly
operated generating units brought an expansion of the overall operating scale
of the Company as well as a significant increase in the Company's power
generation during the first three quarters of 2005. The tariff hike under the
coal-electricity price linkage mechanism during the year coupled with lower
tariff rates for newly added generating units has resulted in commensurate
growth of the Company's revenues and power generation. As the price of coal
remained at a high level, the unit fuel cost amounted to RMB158.63/MWh,
representing an increase of 15.61% over the same period last year. The increase
in revenues could not fully offset the impact of fuel costs upon profits, and
as a result, the Company's net profit decreased compared to the same period
last year. Compared to the second quarter, the coal price was relatively lower
in the third quarter, thus resulting in an increase of the Company's gross
profit.

Huaneng Power International, Inc. develops, constructs, operates and manages
power plants in China nationwide, with a total generation capacity of 21,653MW
on an equity basis. The Company wholly owns sixteen operating power plants, and
has controlling interests in ten operating power companies and minority
interests in four operating power companies. Today, it is one of the largest
independent power producers in China.

Encl:    The unaudited summary financial information of the Company for the
         nine months ended September 30, 2005. The summary financial
         information is published under the listing regulations of the China
         Securities Regulatory Commission. The summary financial information
         was prepared in accordance with "Accounting System for Business
         Enterprises" and "Accounting Standards for Business Enterprises" of
         the People's Republic of China ("PRC GAAP"), which differs from the
         International Financial Reporting Standards ("IFRS") and the
         accounting principles generally accepted in the United States of
         America ("US GAAP"). No reconciliation with IFRS or US GAAP has been
         made in the presentation of the summary financial information.
