Among the power plants of the Company, Fuzhou Power Plant, Jining Power Plant, Nantong Power Plant and Shanghai Shidongkou Second Power Plant have achieved relatively high increase rates in power generation. The increase in power generation of the Company's power plants was mainly attributable to the following reasons: 1. Stable generation capacity of the newly operated generating units 5 and 6 of Jining Power Plant (2 x 135 MW); 2. Increase in power generation was contributed by Xindian Power Plant and Yushe Power Plant, which were acquired in 2003; 3. Significant increase in power consumption in the regions where the Company's power plants operated, thereby providing the conditions for the growth of the Company's power generation; 4. The effective arrangement of maintenance programs during the Chinese New Year and the improved reliability of the Company's generating units, together with stable coal supply, thereby assuring the growth in the Company's power generation; and 5. The Company's enhanced sales and marketing efforts, as well as its enlarged market shares.
