BEIJING,July16,2019 -- Huaneng Power International,Inc. ("HPI",the "Company") (NYSE: HNP; HKEx: 902; SSE: 600011) today announced its power generation for the first half of 2019.

According to the preliminary statistics of Huaneng Power International,Inc.,(the "Company"),forthe second quarter of 2019,the Company's total power generation by power plants within Chinaon consolidated basis amounted to 91.536 billion kWh,representing a decrease of 11.86% over thesame period last year. Total electricity sold by the Company amounted to 86.778 billion kWh,representing a decrease of 11.52% over the same period last year. In the first half of 2019,theCompany's total power generation by the power plants within China on consolidated basis amountedto 195.375 billion kWh,representing a decrease of 6.15% over the same period last year. Totalelectricity sold by the Company amounted to 185.032 billion kWh,representing adecrease of5.78 % over the same period last year. In the first half of 2019,the Company's average on-gridelectricity settlement price for its power plants within China amounted to RMB419.51 per MWh,representing an increase of 0.22% over the same period last year. In the first half of 2019,theCompany's market based electricity soldamounted to 87.553 billion kwh,witha ratio of 47.05% comparing to the corresponding total electricity sold,representing an increase of 10.15 percentage points over the same periodlast year.

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

1. In the first half of the year,the growth rate of the electricity consumption nation-wide showed a significant decline compared to the same period last year;

2. Hydropower and nuclear power generation had increased substantially,crowding out the space for growth in thermal power generation;

3. Areas like East China,Guangdong,Shandong and other regions where the Company has a relatively large proportion of installed capacity have significantly increased the power supply from external sources,thereby crowding out the space for growth of the thermal power generation by local coal-fired power generation units.

The power generations (in billion kWh) of the Company,by regions,are listed below:
