Huaneng Power International, Inc.: Domestic Power Generation in the First Three Quarters of 2020 Decreased by 2.86% Year-On-Year

BEIJING, Oct. 19, 2020

According to the preliminary statistics of Huaneng Power International, Inc., (the "Company"), in the third quarter of 2020, the Company's total power generation by power plants within China on consolidated basis amounted to 110.385 billion kWh, representing an increase of 3.34% over the same period last year. Total electricity sold by the Company amounted to 103.790 billion kWh, representing an increase of 0.81% over the same period last year. In the first three quarters of 2020, the Company's total power generation by the power plants within China on consolidated basis amounted to 293.541 billion kWh, representing a decrease of 2.86% over the same period last year. Total electricity sold by the Company amounted to 275.914 billion kWh, representing a decrease of 4.19% over the same period last year. For the first three quarters of 2020, the Company's average ongrid electricity settlement price for its power plants within China amounted to RMB412.52 per MWh, representing a decrease of 1.24% over the same period last year. For the first three quarters of 2020, the Company's market based electricity sold amounted to 156.228 billion kwh, with a ratio of 56.94% comparing to the corresponding total electricity sold, representing an increase of 5.71 percentage points over the same period last year.

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

1. Affected by the COVID-19 epidemic, the national electricity consumption growth slowed down;
2. The national wind power, photovoltaic and other new energy installations maintained a continuous and large-scale production momentum, thus crowding out the space for growth in thermal power generation. Jilin, Hubei, Chongqing, Jiangsu and other provinces and cities had increased hydropower generation significantly compared to the same period last year, and further squeezed the space for thermal power generation;
3. The increase of new thermal power units in areas where the Company is located had resulted in a decrease in the average utilization hours in those areas. While the Company had fewer new units and with the total installed capacity in the areas increases, the proportion of the Company's share of unit capacity decreases, thus resulting in a decline in thermal power generation compared to the same period last year.
