INFORMATION OF PROJECT ASSETS UNDER THE CAPITAL CONTRIBUTION AGREEMENT


Ganzi Hydropower Company was established and registered on 3 July 2006, with a 
registered capital of RMB50 million. Ganzi Hydropower Company is responsible for the 
development and construction of two hydropower projects, namely the Changhe Dam 
Project (of an installed capacity of 2,600MW) and the Huangjinping Project (of an 
installed capacity of 850MW), both of which were approved by the NDRC in November 
2010 and February 2011, respectively, and are currently under the construction stage. 
Ganzi Hydropower Company has not yet commenced operation as at the date of this 
announcement.

As at the valuation date on 31 March 2011, the total assets of Ganzi Hydropower 
Company amounted to approximately RMB5,478 million, the total liabilities amounted 
to approximately RMB5,106 million and the net assets amounted to approximately RMB372 
million (being the audited value of those assets as at 31 March 2011).


INFORMATION ON THE COMPANY


The Company is principally engaged in the construction and operation of power plants, 
the sale of electricity and thermal power, the repair and maintenance of power 
equipment and power related technical services, with its main service areas being 
in the PRC.


INFORMATION ON CDC 


CDC is a solely State-owned enterprise. Its scope of operations mainly includes the 
development, investment, construction, operation and management of power energy; 
organisation of power (thermal) production and sales; as well as power technology 
development and consultation.


INFORMATION ON GANTOU HYDROPOWER


Gantou Hydropower was established on 30 March 2006 with a registered capital of 
RMB100 million, and is principally engaged in the business of hydropower investments.


REASONS FOR AND BENEFITS OF ENTERING INTO THE CAPITAL CONTRIBUTION AGREEMENT


Through involving CDC as a shareholder of Ganzi Hydropower Company by way of capital 
contribution and share enlargement, new funds will be injected into Ganzi Hydropower 
Company, the capital and financing capabilities of Ganzi Hydropower Company will be 
strengthened, thereby pushing forward the smooth progress of its construction 
projects. Meanwhile, the implementation of such capital contribution and share 
enlargement arrangement will dilute the investment risks of the Company, relieve the 
pressure of development capital and increase the efficiency of capital utilization, 
thereby benefitting the Shareholders of the Company. 

With the involvement of CDC as a shareholder of Ganzi Hydropower Company, Ganzi 
Hydropower Company will further enhance its corporate governance structure, foster 
the cooperation among various related parties and create more room for the 
development of Ganzi Hydropower Company, thereby bringing better returns for the 
Shareholders of the Company.

Upon completion of the capital contribution and share enlargement, Ganzi Hydropower 
Company will still remain as a controlled subsidiary of the Company and the scope of 
consolidation of financial reports of the Company will not be affected.

Since the Changhe Dam Hydropower Project and the Huangjinping Hydropower Project of 
Ganzi Hydropower Company are still under construction, no gain or loss is expected 
to be accrued to the Company as a result of the implementation of the capital 
contribution and share enlargement arrangement contemplated under the Capital 
Contribution Agreement.  


CONNECTED TRANSACTION


As at the date of this announcement, CDC is a controlling Shareholder of the Company. 
CDC and its subsidiaries together hold approximately 34.71% of the issued share 
capital of the Company. Ganzi Hydropower Company is a subsidiary of the Company and 
Gantou Hydropower is a substantial shareholder of Ganzi Hydropower Company. 
Accordingly, CDC and Gantou Hydropower are connected persons of the Company under 
Chapter 14A of the Listing Rules and the entering into of the Capital Contribution 
Agreement constitutes a connected transaction of the Company. 

As each of the applicable percentage ratios (as defined under Rule 14.07 of the 
Listing Rules) in respect of the Capital Contribution Agreement is more than 0.1% 
but less than 5%, the Capital Contribution Agreement is only subject to the 
reporting and announcement requirements under Rules 14A of the Listing Rules and
