HUANENG POWER INTERNATIONAL, INC. By /s/ Huang Long --------------- Name: Huang Long Title: Director Date: August 9, 2005 [GRAPHIC OMITTED] To: Business Editor [For Immediate Release] HUANENG POWER INTERNATIONAL, INC. Announces 2005 Interim Results (Beijing, China, August 9, 2005) Huaneng Power International, Inc. (the Company) [NYSE: HNP; HKEx: 902; SSE: 600011] today announced its unaudited operating results for the six months period ended June 30, 2005. Net operating revenues of the Company and its subsidiaries for the first half of 2005 were RMB18.800 billion (equivalent to approximately US$2.272 billion), representing an increase of 45.02% compared to the same period last year. The net profit attributable to the equity holders of the Company was RMB1.679 billion (equivalent to approximately US$0.203 billion), representing a decrease of 32.32% compared to the same period last year. Earnings per share was RMB0.14, or RMB5.60 (equivalent to US$0.68) for each American Depositary Share. The board of directors does not recommend any interim dividends for year 2005. The increase in the Companys net operating revenues was mainly attributable to the increase in power generation. In the first half of 2005, the Companys total power generation based on a consolidated basis amounted to 71.843 billion kWh, an increase of 47.1% over the same period last year, with such increase mainly attributable to the newly acquired power plants and newly operated generating units. The increase of settlement tariff rates of existing power plants also contributed to the revenues increase. The decrease of the net profit attributable to the equity holders of the Company was mainly due to the substantial increase in fuel costs. The unit fuel cost of the Company for the first half of the year increased by 22% when compared to the same period last year. The increase in fuel costs was mainly attributable to the substantial increase in natural coal prices, increase in transportation costs and declining thermal coal quality. In the first half of 2005, the Company continued to expand its operation scale. During the first half of the year, 2 x 330MW coal-fired generating units of Jiangsu Huaiyin Power Plant Phase II and two hydroelectric power stations of Jialingjiang Qingju and Fujiang Ziyili under Sichuan Hydro Power commenced commercial operation, bringing an additional generation capacity of 539MW on an equity basis. In addition, the Company entered into a transfer agreement with Jiangsu Yueda Investment Company Limited, pursuant to which the Company agreed to acquire the latters 26.36% equity interest in Huaiyin Power Plant Phase I (2 x 220MW coal-fired generating units). The equity interest of Huaiyin Power Plant Phase I owned by the Company was then increased to 90% and the generation capacity on an equity basis of the Company was then increased by 116MW. As at June 30, 2005, the Companys power generation capacity on an equity basis amounted to 21,653MW. In the second half of year 2005, the national economy will continue to maintain steady and rapid development which will bring about stable and rapid growth in electricity demand, thus providing favourable market conditions for the Company to undertake steady increase in power generation. The coal-electricity price linkage mechanism adopted by the State brought about an increase in the settlement tariff levels, which could minimize the negative impact on the generation and operation of the Company brought about by the rise in coal prices. The Company is confident about coping with the changes in the coal market and is determined that under the premises of ensuring an effective and timely supply of fuel, it will endeavour to reduce fuel costs and to complete various tasks set for the year. Huaneng Power International, Inc. develops, constructs, operates and manages large 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. UANENG POWER INTERNATIONAL, INC.

Forward-looking Statement In this press release, our use of the words "expect", "anticipate", "estimate", "project", "forecast", "plan", and similar expressions is intended to identify forward-looking statements. While these statements represent our current judgment on what the future may hold, and we believe these judgments are reasonable, actual results may differ materially due to numerous important factors that are described in the Companys most recent report on SEC Form 20-F which may be revised or supplemented in subsequent reports on SEC Form 20-F. Such factors include, among others, the following: changes in economic conditions; currency-exchange rates or political stability; shortages of fuel supplies, changes in the competitive environment; changes in laws, regulations and tax rates; and, the ability of the corporation to achieve reductions in cost levels to realize production efficiencies and implement capital expenditures at levels and times planned by management. ~ End ~ For any details regarding the interim results, please refer to the announcements published on Wen Wei Po and South China Morning Post dated August 10, 2005.
