Datang International Power Generation Co., Ltd. (the "Company") announces that, based on the 
Company's preliminary statistics, as of 31 December 2011, total power generation of the Company 
and its subsidiaries (the "Group") amounted to 203.7156 billion kWh, representing an increase of

approximately 14.22% when compared to the corresponding period of the previous year.
