[For Immediate Release]


                       HUANENG POWER INTERNATIONAL, INC.
           Announces the Huaneng Shanghai Combined-Cycle-Gas-Turbine
                            Project being Approved

(Beijing, China, March 24, 2005) Huaneng Power International, Inc. (the
"Company") [NYSE: HNP; HKEx: 902; SSE: 600011] today announced that its
Huaneng Shanghai Combined-Cycle-Gas-Turbine Project (the "Project"), with
three 300MW-class generating units being constructed, has recently been
approved by the National Development and Reform Commission.

The Project 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 natural 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.
