[For Immediate Release]


                        HUANENG POWER INTERNATIONAL, INC.
                   Discloses Continuing Connected Transaction

(Beijing, China, March 10, 2006) Huaneng Power International, Inc. (the
"Company") [NYSE: HNP; HKEx: 902; SSE: 600011] announced today that on March 7
2006, the Company entered into a Framework Agreement (the "Agreement") with
China Huaneng Finance Corporation Limited ("Huaneng Finance") to continue to
place deposits with Huaneng Finance and to utilize the notes discounting
services offered by Huaneng Finance. The Company and China Huaneng Group
("Huaneng Group") own 20% and 51% equity interest, respectively, in Huaneng
Finance, a non-bank financial institution in China. Huaneng Group holds
approximately 51.98% equity interests in Huaneng International Power Development
Corporation which in turn owns 42.87% of the Company. The Agreement was entered
into following arms' length negotiations between the Company and Huaneng
Finance. Under the Agreement, the Company will from time to time place deposits
with Huaneng Finance at rates which are no less favorable to the Company than
the rates available from an independent third party for similar services in the
PRC. In addition, the Company will also utilize the notes discounting services
by Huaneng Finance by paying it a service fee on terms more favorable than the
services fees charged by an independent third party for similar services in the
PRC. The Agreement is valid for three years and may be renewed for further
periods to be agreed or be replaced by new agreement upon the parties' mutual
consent.

The Company estimates that the maximum outstanding balances of deposits during
the term of the Agreement will not exceed RMB6,000 million. This cap is proposed
by the Company based on a number of factors, including the expanding asset scale
and the increasing amount of deposits of the Company. The Company also estimates
that the total amount of the notes discounting services during the term of the
Agreement will not exceed RMB1,850 million per annum.





Huaneng Power Int'l, Inc.
Discloses Continuing Connected Transaction...P.2


The Company maintained deposits with Huaneng Finance for the past two years. For
the years 2004 and 2005, the maximum outstanding balances of deposits maintained
by the Company with Huaneng Finance amounted to RMB2,248 million and RMB1,768
million, respectively. Huaneng Finance has also been providing notes discounting
services to the Company during the years of 2004 and 2005. The Company has
decided to use Huaneng Finance for deposit and notes discounting services
because the rates offered by Huaneng Finance are more favourable than those
offered by commercial banks in the PRC in general, and also it believes that
Huaneng Finance's services are more efficient than other financial institutions
in PRC. In addition, connected transactions involved in the Agreement are fair
and reasonable and in the interests of the Company and its shareholders as a
whole. Therefore, the Company proceeds the deposits and notes discounting
services provided by Huaneng Finance.

Huaneng Power International, Inc. develops, constructs, operates and manages
power plants in China nationwide, with a total generation capacity of 23,153MW
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.
