[For Immediate Release]


                       HUANENG POWER INTERNATIONAL, INC.

(Beijing, China, December 9, 2002) Huaneng Power International, Inc. (the

adjustment for Huaneng Fuzhou Power Plant ("Fuzhou Power Plant").

In accordance with the document of the State Development and Planning
Committee, Fujian Province has recently carried out on-grid tariff adjustments
for power plants in the province. As a result, the on-grid tariff for the
Company's Fuzhou Power Plant was adjusted from RMB378.2 per MWh (including
VAT) to RMB365 per MWh (including VAT) effective on December 1, 2002.

The current generation capacity for Fuzhou Power Plant is 1,400MW,
representing 10.08% of the Company's total generation capacity. The Company
will further reinforce the operating management as well as the safety and
stability of the power plant and will strengthen cost controls to offset part
of the impact of the tariff adjustment.

large thermal power plants in China nationwide. With total net generation
capacity of 13,895MW, the Company is the largest independent power producer in
