BEIJING, July 14, 2020

According to the preliminary statistics of Huaneng Power International, Inc., for the second quarter of 2020, the Company's total power generation by power plants within China on consolidated basis amounted to 94.949 billion kWh, representing an increase of 3.73% over the same period last year. Total electricity sold by the Company amounted to 91.473 billion kWh, representing an increase of 5.41% over the same period last year. For the first half of 2020, the Company's total power generation by the power plants within China on consolidated basis amounted to 179.650 billion kWh, representing a decrease of 8.05% over the same period last year. Total electricity sold by the Company amounted to 172.125 billion kWh, representing a decrease of 6.98% over the same period last year. In the first half of 2020, the Company's average on-grid electricity settlement price for its power plants within China amounted to RMB416.65 per MWh, representing a decrease of 0.68% over the same period last year. In the first half of 2020, the Company's market based electricity sold amounted to 84.06 billion kwh, with a ratio of 49.89% comparing to the corresponding total electricity sold, representing an increase of 2.84 percentage points over the same period last year.

The decrease in the Company's power generation was mainly attributable to:

1. Affected by the epidemic in the first quarter, the national economic growth slowed down, and the Company's power generation decreased significantly year-on-year;
2. Since the second quarter, the domestic epidemic situation has been effectively controlled, and the progress of resumption of production in various industries has accelerated. The Company seized the opportunity to actively strive for planned power, and at the same time strengthened power supervision, reduced unit backup, and increased effective generation, realizing a positive year-on-year growth of the Company's power generation in the second quarter, and narrowing the decline in power in the first quarter.
