Power Generation Increases 31.7% in 2005 (Beijing, China, January 11, 2006) Huaneng Power International, Inc. (the "Company") [NYSE: HNP; HKEx: 902; SSE: 600011] today announced its results of power generation in 2005. Based on preliminary statistics, as of December 31, 2005, the Company's total power generation based on a consolidated basis for the year was 150.505 billion kWh, an increase of 31.7% over the same period last year. The power generation of Yushe Power Plant, Huaiyin Power Plant, Qinbei Power Plant, Jining Power Plant and Shantou Power Plant increased significantly. The increase in power generation of the Company's power plants in 2005 was mainly attributed to the following reasons: 1. Power plants acquired in 2004, such as Luohuang Power Plant, Yueyang Power Plant, Yingkou Power Plant, Jinggangshan Power Plant, Pingliang Power Plant and Sichuan Hydro Power have made significant contribution to the increase of the Company's power generation; 2. Yushe Power Plant Phase II and Qinbei Power Plant which were put into operation in the second half of 2004, and Huaiyin Power Plant Phase II and Shantou Power Plant Phase II which were put into operation in 2005 have contributed stable generation in 2005; 3. As a result of rapid economic growth, power demand in the regions where the Company's power plants operated remained strong, thereby providing favorable market conditions for the power generation of the Company; 4. As there were less new generating units being put into operation recently in Shandong power grid, the Company's power plants in Shandong region has posted comparatively rapid growth; 5. Safe and stable operation of generating units has also ensured the growth in the Company's power generation.
