                        MAJOR AND CONNECTED TRANSACTION


o        On 16th April, 2004, the Company entered into the Agreement for
         Transfer of Huaneng Group Interest with Huaneng Group, pursuant to
         which the Company agreed to acquire from Huaneng Group its 40% equity
         interest in Hanfeng Power Plant and 90% equity interest in
         Jinggangshan Power Plant. The purchase price for acquiring the
         Huaneng Group Interest is RMB1,949 million. Half of the purchase
         price will be funded by the Company's cash-on-hand and half by bank
         loans. The purchase price was determined on arm's length terms.


o        On the same day, the Company also entered into the Agreement for
         Transfer of HIPDC Interest with HIPDC, pursuant to which the Company
         agreed to acquire from HIPDC its equity interest in the following

o        HIPDC is the controlling shareholder of the Company and Huaneng Group
         holds 51.98% interest in HIPDC. Therefore, both of HIPDC and Huaneng
         Group are connected persons to the Company. The transactions as
         contemplated by the Acquisition constitute connected transactions to
         the Company.


o        Taking the above two transactions as a whole, the transactions as
         contemplated by the Acquisition also constitute a major transaction
         to the Company.


o        The Company will convene an EGM for the purposes of seeking the
         approvals of Independent Shareholders for the Acquisition (including
         the Transfer Agreements), subject to certain conditions as set out in
         this announcement and the circular to be despatched in respect of the
         Acquisition. According to the Hong Kong Listing Rules, Huaneng Group,
         HIPDC and their respective Associates will abstain from voting in
         respect of the resolution relating to the Acquisition.


o        The Company and the Independent Directors have reviewed the
         Acquisition. The Company has appointed JP Morgan as the financial
         adviser in connection with the Acquisition. The Company has also
         appointed Rothschild as the independent financial adviser to make
         recommendation to the Company's independent board committee and
         shareholders as to whether the terms of the Acquisition are fair and
         reasonable and whether the Acquisition is in the interests of the
         Company and its shareholders as a whole and to advise the Company's
         shareholders on how to vote. The Company expects that the notice of
         the EGM and the Circular giving further information on the
         Acquisition and containing the advice of Rothschild, and the
         recommendation from the Independent Directors are expected to be
         despatched to shareholders within 21 days from the date of this
         announcement.


o        Trading of the Company's H Shares on the Stock Exchange was suspended
         at 9:30 a.m. on 16th April, 2004 pending publication of this
         announcement. Application has been made to the Stock Exchange to
         resume trading of the Company's H Shares with effect from 9:30 a.m.
         on 19th April, 2004.

                         accounts of the power plants. In case of the

                         Power Plant and Luohuang Power Plant respectively.
                         If, by 31st December 2006, the net overdue receivable
                         balances cannot be collected in full, and if HIPDC
                         has not made any payment to the Company in this
                         regard, HIPDC should pay the difference to the
                         Company in proportion to its shareholding interests
                         in Yueyang Power Plant and Luohuang Power Plant
                         respectively. If the net overdue receivable balances
                         have been collected in full or if payment has been
                         made by HIPDC, the amount received over the book
                         balance should be reimbursed to HIPDC based on the
                         shareholding interests of HIPDC in proportion to its
                         shareholding in Yueyang Power Plant and Luohuang
                         Power Plant respectively.

REASONS FOR THE ACQUISITION AND PRICING FACTORS

The Acquisition follows the Company's business and development strategy of
placing equal emphasis on acquisition of existing power plants and development
of new power plants, and is an important strategic move under the backdrop of
deepening power reforms in China. With favourable market conditions of strong
power demand, which is brought about by the rapid and stable economic
development of the PRC, the Company believes that to enlarge its operational
scale by way of acquisition of power assets, thus increasing its market
shares, is conducive to enhancing the competitiveness of the Company and
increasing shareholders' return.


After the completion of the Acquisition, the generation capacity on an equity
basis of the Company will increase by 3,036 MW while the total generation
capacity on an equity basis will increase from 15,736 MW to 18,772 MW,
representing an increase of 19.3%. Upon the completion of the Acquisition and
the acquisition of the 10% interest in Jinggangshan Power Plant from Jiangxi
Province Investment Corporation, the generation capacity on an equity basis of
the Company will increase 3,096 MW while the total generation capacity will
increase from 15,736 MW to 18,832 MW, representing an increase of 19.7%. The
Company will gain 1,050 MW of additional capacity under construction (on an
equity basis).


Further, the Acquisition helps the Company to strengthen its leading position
in Liaoning Province and Hebei Province, which are with rapid economic growth
and strong power demand. The Company's generation capacity on an equity basis
in Liaoning will increase from 2,100 MW to 2,740 MW, representing an increase
of 30.5%. In Hebei Province, by completion of the Acquisition, the Company's
generation capacity on an equity basis will increase from 1,300 MW to 1,828
MW, representing an increase of 40.6%.


The Acquisition also enables the Company for the first time to enter into the
central-south region of China and the provinces with rapid growth in power
demand, namely Jiangxi Province, Hunan Province and Chongqing municipality.
This is consistent with the Company's marketing strategy of "consolidating its
position in coastal regions and exploring the market in Central China".


The Company understands that the State is considering to introduce a pilot
scheme on tariffs reform in the northeast region. However the detail of the
pilot scheme is still under the formulation process. The Company therefore is
unable to ascertain the impact on the operating results of Yingkou Power
Plant, which is located in the northeast region of China, of the
implementation of the proposed tariff reform scheme. As such, the Company has
not taken account of such factor in the evaluation and consideration of the
impact of the Acquisition on the Company's future financial position and
operating results.


The Acquisition price has been determined through arm's length negotiations
between the parties and their respective financial advisors, taking into
account various factors, including the market environments, the technical and
operating conditions of the Power Plants, the Power Plants' earnings
potentials and their abilities to generate cash flow. The Company has also
considered the appraisal report provided by Zhongchenghua which values the
Huaneng Group Interest at RMB1.507 billion and HIPDC Interest at RMB2.721
billion as of 31st December, 2003 using the replacement cost approach. The
total purchase price implies a blended 8.8 times of 2003 earnings of
attributed interest of the five Target Power Plants and a blended 5.7 times
firm value/2003 EBITDA (the firm value includes the account payable of RMB1.26
billion of Yingkou Power Plant which is treated as debt). According to
International Financial Reporting Standards, the total net profit of the
Target Power Plants in 2003 was approximately RMB1.009 billion, of which
RMB516 million would be attributable to the acquired interests (not including
the profit contributed by the acquisition of the 10% interest in Jinggangshan
Power Plant held by Jiangxi Province Investment Corporation). If the
Acquisition had taken place on 1st January, 2003 and half of the acquisition
price had been paid by the Company's cash-on-hand and half by bank loans, the
pro-forma net income of the Company in 2003 would have increased by RMB225
million, or 4.2%. The Company believes that with the growth of the power
markets in which the Target Power Plants operate and through further
strengthening management, the Acquisition will bring satisfactory returns to
the Company.


The board of Directors believes that the Acquisition price and terms are fair
and reasonable to the Company and its shareholders. This transaction is
consistent with the Company's long-term business strategy and will benefit the
Company and its shareholders.
