PROVISION FOR ASSET IMPAIRMENT

This announcement is made by Datang International Power Generation Co., Ltd. (the "Company") 
pursuant to provisions on Inside Information Provisions (as defined under the Rules Governing 
the Listing of Securities on The Stock Exchange of Hong Kong Limited (the "Listing Rules")) 
under Part XIVA of the Securities and Futures Ordinance (Chapter 571, Laws of Hong Kong) and 
Rules 13.09(2)a and 13.10B of the Listing Rules.

The following announcement is made by the board of directors (the "Board") of the Company in 
respect of provision for asset impairment.

I.   SUMMARY OF PROVISION FOR IMPAIRMENT

     (1)  Reason for provision for impairment

          Pursuant to the requirement under the "Notice about the Execution of Closedown of 
          Coal-fired Power Generation Units in Beijing by Beijing Municipal Commission of 
          Development and Reform", Datang International Power Generation Co., Ltd. Beijing 
          Gao Jing Thermal Power Plant (the "Gao Jing Thermal Power Plant"), an enterprise 
          owned by the Company, will shut down all of its coal-fired power generation units 
          by 2014, and indicators of impairment of its assets are shown.

     (2)  Basis of determining the provision for impairment

          Pursuant to the requirements of the PRC Accounting Standard, when assets of an 
          enterprise indicate that "they have or will become idle, their usage has been 
          terminated or they are disposed of ahead of planning", provision for impairment 
          of such corresponding asset groups should be made. As a result, the Company 
          conducted an impairment assessment on the corresponding asset groups of the 
          coal-fired power generation units of Gao Jing Thermal Power Plant, which shows 
          indicators of impairment. The time of the assessment was 31 October 2013, and the 
          assessment result shows that a provision for impairment of approximately 
          RMB646 million on the corresponding asset groups of the coal-fired power 
          generation units of Gao Jing Thermal Power Plant should be made. 

II.   IMPACT OF THE PROVISION FOR IMPAIRMENT ON THE FINANCIAL POSITION OF THE COMPANY

      The Company contemplates to make provision for impairment on the corresponding asset 
      groups of the coal-fired power generation units of Gao Jing Thermal Power Plant in the 
      amount of not more than RMB646 million before the end of 2013 (the exact amount is 
      subject to assessment result by then), and the net profit attributable to equity 
      holders of the Company in the consolidated financial statements of the Company for 
      the year 2013 is expected to decrease by not more than RMB646 million. 


III.  PROCEDURES FOR CONSIDERATION AND APPROVAL OF THE PROVISION FOR IMPAIRMENT 

      The Company convened the fifth meeting of the eighth session of the Board, which 
      considered and approved the "Resolution of Provisions for Impairment of Gao Jing 
      Coal-fired Power Generation Units" on 6 December 2013.

      The Board is of the view that according to the PRC Accounting Standard, the provision 
      for asset impairment is conducted basing on a prudent approach, is well-founded, and 
      fairly reflects the condition of the Company's assets, and therefore approved the 
      provision for the impairment.

IV.   OTHERS

      In order to meet the load demand from the power grids in Beijing and the demand for 
      heating in the Beijing area, the Company convened the twenty-fifth meeting of the seventh 
      session of the Board on 6 June 2012 and considered and approved the "Resolution on 
      Investment in Constructing the Beijing Gao Jing Gas Thermal Power Project", approving the 
      investment in the construction of the Beijing Gao Jing Gas Thermal Power Project. The 
      Beijing Gao Jing Gas Thermal Power Plant project is located at the western side of the 
      Company's Beijing Gao Jing Thermal Power Plant, with a construction scale of three 9F-grade
      gas-steam combined cycle back-pressure heating generating units with a total installed 
      capacity of 1,380 MW. It was expected that the project would commence production in 
      succession by the end of 2014. After commencing production, the project would help optimise 
      the Company's power sources structure, consolidate its development status in the Beijing 
      area and strengthen its profit base.
