ANNOUNCEMENT ON COMPLETION OF POWER
GENERATION IN THE FIRST HALF OF 2018

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., (the “Company”), for the second quarter of 2018, the Company’s total power generation by power plants within China on consolidated basis amounted to 103.856 billion kWh, representing an increase of 14.52% over the same period last year. Total electricity sold by the Company amounted to 98.075 billion kWh, representing an increase of 14.54% over the same period last year. In the first half of 2018, the Company’s total power generation by the power plants within China on consolidated basis amounted to 208.167 billion kWh, representing an increase of 11.51% over the same period last year. Total electricity sold by the Company amounted to 196.387 billion kWh, representing an increase of 11.51% over the same period last year. In the first half of 2018, the Company’s average on-grid electricity settlement price for its power plants within China amounted to RMB418.57 per MWh, representing an increase of 2.72% over the same period last year.

The increase in the Company’s power generation was mainly attributable to:

1.
The growth in the macro-economy was better than expected;

2.
The growth rate of electricity consumption for residents’ electricity, tertiary industries and non- high-energy-consuming manufacturing industries increased significantly; and

3.
In the first half of the year, the growth rate of hydropower generation in the country was relatively low, far lower than the growth rate of the electricity consumption of the whole society and national power generation. The Company has a relatively higher proportion of thermal power units and seized the opportunity to increase power generation.
