[For Immediate Release]


                       HUANENG POWER INTERNATIONAL, INC.
                     Announces Tariff Adjustments for its
                     Four Power Plants in Jiangsu Province


(Beijing, China, February 12, 2003) Huaneng Power International, Inc. (the
"Company") [NYSE: HNP; HKEx: 902; SSE: 600011] today announced the tariff
adjustments for its four power plants in Jiangsu Province, including Huaneng
Nanjing Power Plant ("Nanjing Power Plant"), Huaneng Nantong Power Plant
("Nantong Power Plant), Huaneng Huaiyin Power Plant ("Huaiyin Power Plant) and
Huaneng Taicang Power Plant ("Taicang Power Plant").
In accordance with the document of the State Development and Planning
Committee, Jiangsu Province has recently carried out on-grid tariff
adjustments for power plants invested by multiple parties in the province. As
a result, the tariffs for the Company's four power plants were adjusted as
follows (all the tariffs mentioned below include VAT):

-     The on-grid tariff for Nanjing Power Plant was adjusted from RMB336.1
      per MWh to RMB334 per MWh;

-     The on-grid tariff for Nantong Power Plant was adjusted from RMB334.6
      per MWh to RMB334 per MWh;

-     The on-grid tariff for Huaiyin Power Plant was adjusted from RMB345.6
      per MWh to RMB343 per MWh;

-     The on-grid tariff for Taicang Power Plant was adjusted from RMB374 per
      MWh to RMB365 per MWh.

The average tariff downward for these four power plants is RMB2.9 per MWh, and
the adjusted tariffs were effective from January 30, 2003.

The tariff adjustments are within the estimates of the Company, and the
Company has full confidence to partly offset the impact of the tariff
adjustments through further reinforcing the management and cost controls and
increasing its market shares.

Huaneng Power International, Inc. develops, constructs, operates and manages
large thermal power plants in China nationwide. Its current generation
capacity on an equity basis is 14,363MW.
