BEIJING, Jan. 14, 2022 /PRNewswire/ -- Huaneng Power International, Inc. ("HPI", the "Company") (NYSE: HNP; HKEx: 902; SSE: 600011) today announced its electricity sales for the whole year of 2021.

According to the preliminary statistics of Huaneng Power International, Inc. (the "Company"), for the fourth quarter of 2021, the Company's total electricity sold by power plants within China on consolidated basis amounted to 107.050 billion kWh, representing an increase of 2.95% over the same period of 2020. For the whole year of 2021, total electricity sold by power plants within China on consolidated basis amounted to 430.165 billion kWh, representing an increase of 13.23% over the same period of 2020. For the whole year of 2021, the Company's average on-grid electricity settlement price for its power plants within China was RMB431.88 per MWh, representing an increase of 4.41% over the same period of 2020. For the whole year of 2021, the Company's market-based electricity sold ratio was 61.63%, representing an increase of 3.3 percentage points compared to the same period of 2020.

The increase in the Company's total electricity sold was mainly attributable to:

1. In 2021, the sustained heavy demand for electricity nation-wide prompted significant increase in power generation. The power plants of the Company in areas such as Chongqing, Guangdong, Zhejiang, Shanghai, Fujian, Hunan, Jiangsu, Gansu and Hubei saw a relatively large growth in power generation;

2. The output of hydropower plants was less than expected, while thermal power units with a greater percentage of installed capacity of the Company sustained a rapid growth in power generation. In addition, during the peak seasons in winter, the thermal power load of the Company maintained at a high level, which further promoted the growth of power generation; and

3. The Company continued to promote green and low-carbon transformation, which led to the fast growth in new energy generation year on year.

The electricity sold (in 100 million kWh) of the Company in China are listed below:
