(a Sino-foreign joint stock limited company incorporated in the People's
Republic of China) (Stock Code: 902)

                       Overseas Regulatory Announcement
                  Resolutions passed by the Board of Directors

This announcement is made pursuant to Rule 13.09(2) of the Rules Governing the
Listing of Securities on The Stock Exchange of Hong Kong Limited ("Listing
Rules").

According to the applicable laws and the articles of association of Huaneng
Power International, Inc. (the "Company"), the fifth session of the board of
directors of the Company (the "Board") has resolved unanimously in writing the
following resolutions. The transactions as contemplated by such resolutions do
not constitute transactions under Chapter 14 and Chapter 14A of the Listing
Rules.

1.    The proposal regarding the listing plan of Shenzhen Energy Group Limited
      Company has been considered and approved

      It was resolved that Shenzhen Energy Group Limited Company ("Shenzhen
      Energy Group") would implement the listing proposal (the "Listing Plan")
      of Shenzhen Energy Investment Co., Ltd. ("SEI") by way of asset sale in
      the following manner:

      (1)   Shenzhen Energy Group to subscribe an aggregate of not more than
            800,000,000 new shares to be issued by SEI by injection of certain
            assets held by Shenzhen Energy Group ("SEG Subscription"); and

      (2)   upon completion of the SEG Subscription, Shenzhen Energy Group will
            be dissolved through appropriate arrangement at appropriate time so
            as to achieve the aim that Shenzhen State-owned Assets
            Administration Commission ("SSAAC") and the Company could each
            directly hold shares in SEI.

      The Board of the Company was of the view that it was in the interest of
      the Company and its shareholders as a whole to support the Listing Plan.

2.    The proposal on the subscription of the shares of SEI at its new issue by
      way of cash was considered and approved

      It was resolved to subscribe an aggregate of not more than 200,000,000
      new shares of SEI at its new issue at the price of RMB7.60 each by way of
      cash so as to ensure that the Company will have an effective interest in
      SEI of not less than 25% of the total issued shares of SEI.

      The Board of the Company was of the view that the subscription of the
      shares of SEI at its new issue with a view of ensuring the Company's
      interests in SEI to maintain at the level of not lower than 25% is
      consistent with the Company's long-term development strategy and the
      long-term benefit of the shareholders of the Company as a whole.

3.    The proposal to authorise the directors of the Company to handle and
      implement the above-mentioned resolutions and any other matters ancillary
      thereto was considered and approved

      It was resolved to authorise Mr. Na Xizhi and Mr. Huang Long (both are
      directors of the Company) to act on behalf of the Company (1) to take all
      necessary action to deal with the matters relating to the Listing Plan,
      including but not limited to executing all necessary documents on the
      Company's behalf; (2) to represent the Company to reach all necessary
      agreement or arrangement with SSAAC and take all necessary actions to
      achieve the aim of having SSAAC and the Company each directly holding
      shares in SEI as soon as possible after the listing of SEI; and (3) to
      take all necessary actions in relation to the matters on the subscription
      of the shares of SEI at its new issue by way of cash, including but not
      limited to executing all necessary documents.

                                                           By Order of the Board
                                                                 Huang Jian
