As resolved at the 2019 annual general meeting of Huaneng Power International, Inc. (the “Company”) held on 16 June 2020, the Company has been given a mandate to issue super short-term debentures (in either one or multiple tranches on rolling basis) with a principal amount of up to RMB30 billion (which means that the outstanding principal balance of the super short-term debentures in issue shall not exceed RMB30 billion at any time within the period as prescribed therein) within the period from approval obtained at 2019 annual general meeting to the conclusion of the 2020 annual general meeting.

The Company has recently completed the issue of the fourth tranche of the Company’s super short- term debentures for 2021 (the “Debentures”). The total issuing amount was RMB2 billion with a maturity period of 37 days whereas the unit face value is RMB100 and the interest rate is 2.10%.

Shanghai Pudong Development Bank Co., Ltd. and Bank of Communications Co., Ltd. act as the lead underwriters to form the underwriting syndicates for the Debentures, which were placed through book-building and issued in the domestic bond market among banks. The proceeds from the Debentures will be used to supplement the working capital of the headquarters of the Company, adjust debts structure and repay bank loans and the debt due.

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