Huaneng Power International, Inc. Power Generation Within China Increased by 9.12% for the Year of 2018

BEIJING,Jan. 21,2019 -- Huaneng Power International,Inc. ("HPI" or the "Company") (NYSE: HNP; HKEx: 902; SSE: 600011) today announced its power generation statistics for the whole year of 2018.

According to the preliminary statistics of the Company,in the fourth quarter of 2018,the Company's total power generation by power plants within China on consolidated basis amounted to 103.707 billion kWh,representing an increase of 3.49% over the same period last year. Total electricity sold by the Company amounted to 97.953 billion kWh,representing an increase of 4.05% over the same period last year. For the whole year of 2018,the Company's total power generation by the power plants within China on consolidated basis amounted to 430.457 billion kWh,representing an increase of 9.12% over the same period last year,and the total electricity sold by the Company amounted to 405.943 billion kWh,representing an increase of 9.30% over the same period last year. For the whole year of 2018,the Company's average on-grid electricity settlement price for its power plants within China amounted to RMB 418.48 per MWh,representing an increase of 1.08% over the same period last year. For the whole year of 2018,the Company's market based electricity sold amounted to 175.233 billion kWh,with a ratio of 43.48% comparing to corresponding total electricity sold,representing an increase of 10.01 percentage points compared to the same period last year (33.47%).

The increase in the Company's power generation was mainly attributable to the following reasons: (1) The growth of the national total electricity consumption was better than those anticipated at the beginning of the year,especially the electricity consumption by the tertiary industry and urban and rural residents maintained at a double-digit growth; and (2) Affected by factors such as increased demand and reduced water supply,the Company's thermal power utilization hours rebounded significantly; and (3) The new gas,wind-power and photovoltaic units contributed to the growth of power generation.

The power generation (in billion kWh) in each region of the Company's power plants within China are listedbelow:
