                       HUANENG POWER INTERNATIONAL, INC.
        Entered into Entrusted Management Agreement with Huaneng Group

(Beijing, China, April 11, 2005) Huaneng Power International, Inc. (the
"Company") [NYSE: HNP; HKEx: 902; SSE: 600011] entered into an Entrusted
Management Agreement (the "Agreement") with Huaneng Group today. Under the
Agreement, Huaneng Group will be entrusted to manage certain affairs of
Sichuan Huaneng Hydro Power Development Limited Liability Company (the
"Sichuan Hydro Power") and the management fee totals RMB2.42 million, of which
60% will be paid by the Company according to its equity interest in Sichuan
Hydro Power. The management fee was determined on an arm's length basis.

The Company acquired a 60% equity interest of Sichuan Hydro Power in 2004 from
Huaneng Group, which is an indirect controlling shareholder of the Company.
Sichuan Hydro Power is a company engaged in developing, investing in,
constructing, operating and managing hydro power as well as power generation.
The Company entered into the Agreement with Huaneng Group in order to utilize
and benefit from the extensive experience and resources of Huaneng Group in
managing hydro power plants.

Under the Agreement, the services to be provided by Huaneng Group will
include, among others, the management of project development, power sales,
production, construction, human resources and certain administrative affairs,
but will not include the management of financial, auditing and changes in
equity and assets related matters. Under the Agreement, the management fee to
be paid by the Company to Huaneng Group is determined based on such factors as
management costs, risk premium and profit and is subject to certain
adjustments pursuant to a formula based on these factors. The term of the
Agreement is one-year but will be automatically renewed unless either party
opposes to such renewal. The Agreement may be terminated by either party upon
the occurrence of certain events specified in the Agreement.

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, it is one of the largest independent
power producers in China.
