[For Immediate Release]


                       HUANENG POWER INTERNATIONAL, INC.
                  Obtained Approval on the Reconstruction and
                   Expansion Project of Xindian Power Plant


(Beijing, China, September 7, 2005) Huaneng Power International, Inc. (the
"Company") [NYSE: HNP; HKEx: 902; SSE: 600011] announced that the
reconstruction and expansion project of Shandong Huaneng Xindian Power Plant
(or Xindian Power Plant Phase III) has been confirmed by and registered with
the National Development and Reform Commission recently.

The project comprises the construction of two 300MW domestic critical
coal-fired generating units with flue-gas desulphurization facilities being
constructed at the same time. After being put into operation, the power plant
will need a supply of coal of about 1.5 million tonnes annually, and the coal
will be supplied from Shanxi by rail via the power plant's special railway to
the power plant. The investment amount (including capitalized interest) of the
project, which is calculated according to the pricing level of year 2004, is
estimated to be approximately RMB2.47 billion, 20% of which is equity capital
to be funded by the Company (95%) and Zibo Municipal Linzi District
Public-owned Asset Management Limited Company (5%) respectively, with the
remaining portion to be funded by bank loans.

Huaneng Power International, Inc. develops, constructs, operates and manages
power plants in China nationwide, with a total generation capacity of 21,653MW
on an equity basis. The Company wholly owns sixteen operating power plants,
and has controlling interests in ten operating power companies and minority
interests in four operating power companies. Today, it is one of the largest
independent power producers in China.
