OVERSEAS REGULATORY ANNOUNCEMENT ISSUE OF SUPER SHORT-TERM DEBENTURES

This announcement is made pursuant to Rule 13.09(2) of the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited (the “Listing Rules”).

As resolved at the 2010 Annual General Meeting of Huaneng Power International, Inc. (the “Company”), the Company may apply to the National Association of Financial Market Institutional Investors for the quota to issue super short-term debentures with a principal amount of not exceeding RMB20 billion (to be issued with such period on a rolling basis). On 9 May 2012, the Company received a notification on acceptance of registration (Zhong Shi Xie Zhu [2012] No. SCP5) from the National Association of Financial Market Institutional Investors, accepting the registration of the super short-term debentures of the Company.

The Company has completed the issue of the third tranche of the Company’s super shortterm debentures for 2012 on 20 August 2012 (the “Debentures”). The total issuing amount was RMB5 billion with a maturity period of 270 days whereas the unit face value is RMB100 and the interest rate is 3.70%.

China Construction Bank Corporation and China Merchants Bank Co. Ltd. act as the joint lead underwriters to form the underwriting syndicate for the Debentures, which will be placed through book-building and issued in the domestic bond market among banks. The proceeds from the Debentures will be used principally to settle part of the bank loans so as to improve its debt structure and to supplement short term operational working capital.
