3.    MANAGEMENT'S DISCUSSION AND ANALYSIS

3.1   Brief analysis on the overall situation of the operating activities of
      the Company during the reporting period

      Compared to the same period last year, the newly acquired and operating
      generating units brought about an expansion of the Company's overall
      operating scale in the first quarter of 2005, while the average tariff
      rate increased slightly and power generation and revenue continued to
      grow substantially. The price of coal has been rising since April 2004
      and now still remains at a high level. Therefore, compared to the same
      period last year, the unit fuel cost increased significantly, thus
      causing a substantial decrease in gross margin in power sale. The
      expansion of the operating scale could not fully offset the increases in
      fuel costs and fixed costs, and as a result, the profits of the Company
      decreased compared to the same period last year.

      As the price of coal has continuously increased since April 2004 and
      still remains at a high level, the unit fuel cost increased
      substantially, compared to the same period last year. The gross margin of
      power sale decreased significantly. The gross margins of the first
      quarter of 2004, the whole year of 2004 and the first quarter of 2005 are
      30.25%, 25.46% and 18.70% respectively.

            The related transactions occurred during the reporting period are
            the same kind of transactions as estimated for the year of 2005.

      5. Reasons of the transactions and impact on the Company


            (1)   The purchase of coal from Huaneng International Trading can
                  take advantages from the scale and expertises of China
                  Huaneng Group, and can help to reduce purchase costs.

            (2)   Time Shipping is a company owned by China Huaneng Group
                  specialising in maritime transportation. Compared with other
                  similar companies, it has strengths in management and service
                  qualities and enjoys good reputation. Therefore,
                  transportation of part of the Company's coal was undertaken
                  by Time Shipping.

            (3)   Such related transactions will be conducted in strict
                  compliance with the aforesaid pricing policy and basis of
                  pricing. Such transactions will not have any adverse impact
                  on the financial position and operating results of the
                  reporting period as well as those in future.

II.   Impact of the commencement of operation of the power market of the
      northeastern region on the Company.

      The power market of the northeastern region commenced operation on 15
      January 2004 by adopting a "dual pricing with full competition" mode. The
      market has been in trial operation since the end of 2004 after several
      simulated operations and has held its annual price bidding.

      Recently, the Company has received the Notice Regarding the Commencement
      of Trial Monthly Price Bidding in Power Market of the Northeastern Region
      issued by the National Development and Reform Commission and the
      Electricity Regulatory Commission. Such notice has included an Opinion to
      Improve the Trail Run of the Power Market in the Northeastern Region,
      which requests that the trial monthly price bidding in the power market
      of the northeastern region shall commence in April 2005.

      The Company has 3 power plants in the northeastern region, namely Dalian
      Power Plant, Dandong Power Plant and Yingkou Power Plant with a total of
      8 generating units and an aggregate generation capacity of 2,740 MW. All
      of them are located in the loading centre in Liaoning.

      At the same time as the Company actively supports and participates in the
      establishment of the power market of the northeastern region, the Company
      has also formulated a clear strategy by conducting serious analysis and
      evaluation of the market conditions, with a view to leveraging its
      competitive strengths under a fair, reasonable and open market
      environment.
