[For Immediate Release]


                       HUANENG POWER INTERNATIONAL, INC.
        Announces Proposal on Reform of its Non-trading Domestic Shares

(Beijing, China, March 7, 2006) Huaneng Power International, Inc. (the
"Company") [NYSE: HNP; HKEx: 902; SSE: 600011] announced today that the
Company's share reform has officially started and that the largest shareholder
of the Company, Huaneng International Power Development Corporation ("HIPDC")
and its controlling shareholder, China Huaneng Group ("Huaneng Group"), have
made a proposal for converting all of the Company's non-trading domestic shares
into domestic A shares that will be listed and traded on the Shanghai Stock
Exchange. Under such proposal, Huaneng Group and HIPDC will offer 2.8 shares to
each holder of publicly traded A shares for every ten (10) A shares held by
such a holder whose name appears on the Company's A share register as of the
close of business on the record date set for the purpose of implementing this
reform. Under the relevant Chinese regulations and the Company's articles of
association, this proposal is subject to the approval by the holders of the
Company's A shares voting as a class as well as approval by the relevant
Chinese government authorities.

If approved and implemented, the above reform proposal, which is designed to
balance the interests of holders of the Company's non-trading domestic shares
and those of trading A shares, will be transactions occurring among the holders
of the Company's domestic shares only, and will not have any effect on the
Company's assets, liabilities, shareholder's interests, total issued shares or
net profits. In addition, Huaneng Group and Huaneng International Power
Development Corporation will bear all the costs and expenses that may arise in
connection with this reform.

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.
