HUANENG POWER INTERNATIONAL, INC. By /s/ Huang Long -------------- Name: Huang Long Title: Company Secretary Date: April 29, 2006 [HUANENG LOGO OMITTED] To: Business Editor [For Immediate Release] HUANENG POWER INTERNATIONAL, INC. Announces Results for the First Quarters of 2006 Net Profit Rises 38.66% to RMB 1.094 billion (Beijing, China, April 25, 2006) Huaneng Power International, Inc. (the "Company") [NYSE: HNP; HKEx: 902; SSE: 600011] today announced its unaudited results for the three months ended March 31, 2006. Under the PRC Accounting Standards, for the first quarter of 2006, the Company realized operating revenues of RMB10.108 billion, representing an increase of 8.49% over the same period last year. Net profit amounted to RMB1.094 billion, representing an increase of 38.66 % over the same period last year. The Company's total power generation on a consolidated basis amounted to 37.096 billion kWh, an increase of 2.79% over the same period last year. The Board of Directors was satisfied with the Company's first quarter production and operation results. During the first quarter of 2006, the power output, revenues, net profit and earnings per share of the Company increased to various extents when compared to the first quarter of 2005. As regards power output, due to continued growth in social power demand, the new generating units of the Company have obtained a share in the market and the power output of the Company increased by 2.79% when compared to the same period of last year. However, as a result of an increasing number of new generating units and intensified market competition, the average utilization hours of the Company's generating units have declined when compared to the same period of last year. As regards profitability, the profit margin of power sale for the first quarter of 2006 has risen when compared to the same period of last year mainly because of the period-end upswing effect of the "Coal-Electricity Price Linkage Mechanism" policy implemented in May 2005. As regards the costs of coal for power generation, the unit fuel cost during the first quarter of 2006 was basically the same as that of the same period of last year. Accordingly, the revenues, net profit and earnings per share of the Company for the first quarter of 2006 increased by 8.49%, 38.66% and 28.57% respectively when compared to the first quarter of 2005. Huaneng Power International, Inc. develops, constructs, operates and manages power plants in China nationwide, with a total generation capacity of 23,549MW on an equity basis. The Company wholly owns sixteen operating power plants, and has controlling interests in twelve 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 three months ended March 31, 2006.
