Based on preliminary statistics, as of December 31, 2004, the Company's total power generation based on a consolidated basis for the year was 114.28 billion kWh, an increase of 25.7% over the same period last year. The power generation of Yushe Power Plant, Jining Power Plant, Fuzhou Power Plant, Dalian Power Plant and Jinggangshan Power Plant increased significantly. The increase in 2004 power generation of the Company was mainly attributed to the following factors: 1. Power generation of the Company's power plants increased in pace with the increase in power demand and power consumption in the regions where the Company's power plants operated owing to the economic growth in such areas; 2. The Company's power generation increased significantly owing to half-year power generation contributed by Yingkou Power Plant, Jinggangshan Power Plant, Yueyang Power Plant and Luohuang Power Plant which were acquired by the Company in the first half of 2004; 3. The full-year production of two generating units at Jining Power Plant which were commenced operation in 2003 has enhanced the Company's generation capacity and the newly operated generating units at Yushe Power Plant Phase II and Qinbei Power Plant have also contributed to the increase of the Company's power generation; 4. The effective arrangement of maintenance programs has improved the availability of the Company's generating units; and 5. Improved reliability of the Company's generating units through technical innovation has assured growth in the Company's power generation. Huaneng Power Int'l, Inc.
