II.   Brief Analysis on Power Generation

      1. As a result of adjustment on economic structure, slowdown of economic 
         growth, significant decline on the growth of the total power 
         utilization level from the whole society, as well as the plan of the 
         Group to carry out maintenance of the Group's thermal power generation
         units, the average utilization hours of the Group's thermal power 
         generation units declined, thereby leading to a decline in the power 
         generation of part of the thermal generation units of the Company.

      2. The Group's hydro-electric power generation units were affected by an
         increase in inflow water in the basin where the generation units 
         situated and the expansion in capacity of the generation units on a 
         year-to-year basis. The power generation provided by the 
         hydro-electric power generation units of Chongqing Datang 
         International Pengshui Hydropower Development Company Limited and 
         Chongqing Datang International Wulong Hydropower Development Company
         Limited demonstrated a more substantial increase on a year-to-year 
         basis.

      3. Since the capacity and efficiency of the Group's wind power generation
         units were enhanced on a year-to-year basis, the wind power generation
         demonstrated a more substantial increase on a year-to-year basis.
