OVERSEAS REGULATORY ANNOUNCEMENT ISSUE OF SHORT-TERM NOTES

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”) held on 17 May 2011, the Company has been given a mandate to issue within the PRC short-term notes of a principal amount not exceeding RMB10 billion (in either one or multiple tranches) within 12 months from the date on which the shareholders’ approval was obtained.

The Company has completed the issue of the first tranche of the Company’s short-term notes for 2012 on 17 April 2012 (the “Notes”). The total issuing amount was RMB5 billion with a maturity period of 365 days whereas the unit face value is RMB100 and the interest rate is 4.41%.

China Construction Bank Corporation acts as the lead underwriter to form the underwriting syndicate for the Notes, which will be placed through book-building and issued in the domestic bond market among banks. The proceeds from the Notes 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.

The relevant documents in respect of the Notes are posted on China Money and Shanghai Clearing House at websites of www.chinamoney.com.cn and www.shclearing.com, respectively.
