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

(Beijing, China, March 15, 2006) Huaneng Power International, Inc. (the
"Company") [NYSE: HNP; HKEx: 902; SSE: 600011] announced today that the
proposed non-trading domestic share reform program announced last week has been
amended. Under such amended proposal, Huaneng Group and Huaneng International
Power Development Corporation ("HIPDC") will offer 3 shares (as apposed to 2.8
shares that were originally offered) 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. This amendment would increase the
total number of shares offered by Huaneng Group and HIPDC in connection with
this reform from 140,000,000 shares to 15,000,000 shares. Except for the above,
all other terms and conditions of the originally announced share reform
proposal will remain unchanged.

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.
