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 first quarter of 2018, the Company's total power generation by power plants within China on consolidated basis amounted to 104.311 billion kWh, representing an increase of 8.67% over the same period last year. Total electricity sold by the Company amounted to 98.313 billion kWh, representing an increase of 8.64% over the same period last year. For the first quarter of 2018, the Company's average on-grid electricity settlement price for its power plants within China amounted to RMB423.55 per MWh, representing an increase of 4.33% over the same period last year.

1.
the increase in electricity demand in various industries and the increase in the electricity consumption due to extreme cold weather, the electricity consumption of the whole country grew rapidly in the first quarter;

2.
reduction in water supply, decrease in hydropower generation and growth of thermal power generation in some areas.
