For the third quarter of 2018,the power generation of Tuas Power Limited in Singapore,which is wholly-owned by the Company,accounted for a market share of 20.6% in Singapore,representing a decrease of 1.8 percentage points compared to the same period last year (22.4%). In the first three quarters of 2018,the accumulated power generation accounted for a market share of 20.8%,representing a decrease of 1 percentage point compared to the same period last year.

The Company's wholly-owned Heilongjiang Shuangyu Photovoltaic Project with a total capacity of 13.4 MW,the 34 MW Chongqing Fengjie Jinfengshan Wind Farm,the 37.4 MW Jiangxi Gaolongshan Wind Farm,the Hubei Zhongxiang Hujiawan Wind Power Project with a total capacity of 126MW and the 13.8 MW Jiangsu Yizheng Wind Farm,and the Hainan Chengmai Photovoltaic Project with a total capacity of 32MW (in which the Company has a 91.8% interest) were put into operation in the third quarter respectively.

In addition,in August 2018,Huaneng Shandong Power Generation Co.,Ltd.
