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

Huaneng Power International, Inc. (the "Company") has obtained approval from
the National Development and Reform Commission of the PRC in respect of the
project of constructing three 300 MW-class generating units at Huaneng
Shanghai Combined-Cycle-Gas-Turbine Power Plant.

Huaneng Shanghai Combined-Cycle-Gas-Turbine Power Plant is located in between
Huaneng Shanghai Shidongkou First Power Plant and Huaneng Shanghai Shidongkou
Second Power Plant. After being put into operation, the power plant will need
a supply of gas of about 900 million cubic meters annually, and the gas will
be supplied directly through Shanghai's main gas pipeline to the interface
outside the walls of the power plant. The investment amount (including
capitalized interest) of the project, which is calculated according to the
pricing level of year 2002, is estimated to be approximately RMB3.51 billion,
25% of which is equity capital to be funded by the Company (70%) and Shenergy
Company Limited (30%) respectively, with the remaining portion to be funded by
bank loans.

The Company develops, constructs, operates and manages large thermal power
plants in China nationwide, with a total generation capacity of 21,418MW on an
equity basis. The Company wholly owns 16 operating power plants, and has
controlling interests in ten operating power companies and minority interests
in four operating power companies. Today, the Company is one of the largest
independent power producers in China.

                                               By Order of the Board
