POWER GENERATION WITHIN CHINA INCREASED BY 24.89% IN THE FIRST QUARTER OF 2017

This announcement is made pursuant to Rule 13.10B of the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited.

According to the preliminary statistics of Huaneng Power International, Inc. (“Huaneng Power” or “the Company”) , for the first quarter of 2017, the Company’s total power generation by the power plants within China on consolidated basis amounted to 95.988 billion kWh, representing an increase of 24.89% over the same period last year. Total electricity sold by the Company amounted to 90.496 billion kWh, representing an increase of 24.44% over the same period last year. For the first quarter of 2017, the Company’s average on-grid electricity settlement price for its power plants within China amounted to RMB405.97 per MWh, representing an increase of 1.02% over the same period last year.

The main reasons attributable to the increase in the Company’s power generation were: 1. the Company’s acquisition of power assets in Heilongjiang, Jilin and Shandong areas was conducive to the substantial increase in the level of power generation of the Company; and 2. the Company’s thermal power generation in central China and eastern China rose year-on-year.

The power generation (in billion kWh) by each region of the Company’s domestic power plants are listed below:
