                             CONNECTED TRANSACTION



-------------------------------------------------------------------------------
o     On 26th May 2005, the Company entered into the Transfer Agreement with
      Jiangsu Yueda, pursuant to which the Company agreed to acquire from
      Jiangsu Yueda its 26.36% equity interest in Huaiyin Power Plant Phase I
      for a consideration of RMB220 million. The purchase price will be funded
      by the Company's internal cash surplus. The purchase price was determined
      on arm's length terms.

o     Huaiyin Power Plant Phase I is a non wholly-owned subsidiary of the
      Company. As a substantial shareholder of Huaiyin Power Plant Phase I
      holding 26.36% interest thereof, Jiangsu Yueda is a connected person to
      the Company. The transaction as contemplated by the Acquisition thus
      constitutes a connected transaction to the Company.

o     Since the relevant percentage ratios calculated pursuant to Rule 14.07
      of the Hong Kong Listing Rules in connection with the Acquisition are all
      less than 2.5%, the Acquisition is only subject to the reporting and
      announcement requirements set out in Rules 14A.45 and 14A.47 of the Hong
      Kong Listing Rules and is exempt from the independent shareholders'
      approval requirements.

                                         price was determined with reference
                                         to, inter alia, the net asset value of
                                         Huaiyin Power Plant Phase I as at 31st

PRC-built coal-fired generating units commenced operation in November 1993 and
August 1994 respectively. In order to reduce energy consumption and increase
capacity, one generating unit of Huaiyin Power Plant Phase I was upgraded in
October 2001, which increased the maximum generation capacity of that unit to
220MW. The upgrading of the second generation unit was completed in 2002 and by
then the actual generation capacity of Jiangsu Huaiyin Power Plant reached
440MW.

The coal supply for Huaiyin Power Plant Phase I is primarily from Anhui
Province, Shanxi Province, Henan Province and Shaanxi Province. Electricity
generated by Huaiyin Power Plant Phase I is transmitted to the Jiangsu Power
Grid through 110kV and 220kV transmission lines.
