According to the preliminary statistics of the Company, for the fourth quarter of 2016, the Company's total power generation by its power plants within China amounted to 81.097 billion kWh on consolidated basis, representing an increase of 2.02% over the same period last year, and the total electricity sold by the Company amounted to 76.064 billion kWh, representing an increase of 1.57% over the same period last year. For the whole year of 2016, the Company's total power generation by its power plants within China amounted to 313.690 billion kWh on consolidated basis, representing a decrease of 2.13% over the same period last year, and the total electricity sold by the Company amounted to 295.800 billion kWh, representing a decrease of 2.05% over the same period last year. For the whole year of 2016, the Company's average on-grid electricity settlement price for its power plants within China amounted to RMB396.60 per MWh, representing a decrease of 10.53% over the same period last year.

The decrease in the Company's power generation for the year of 2016 was mainly attributable to the following reasons: (1) the installed capacity growth outpaced the growth of the nationwide power consumption while the utilization hours of coal-fired power generation units saw a year-on-year fall; (2) the growth of the Company's installed capacity was below the average of its regional peers; and (3) the launch of new nuclear power generators in the areas including Liaoning, Guangdong, Fujian and Hainan had a relatively significant impact on the output of the coal-fired power generation units in these regions.
