Our Business
(1) Stable growth of installed capacity In 2020, the Group’s consolidated installed capacity of wind power increased by 1,056.2 MW, and its accumulative consolidated installed capacity was 5,471.95 MW; its attributable installed capacity of wind power increased by 1,026.28 MW, and its accumulated attributable installed capacity was 4,965.90 MW. The Group’s commercial operation project capacity during the year increased by 694.1 MW, and its accumulated commercial operation project capacity was 4,400.25 MW. As at 31 December 2020, the total designed capacity of the wind power projects under construction of the Group was 632 MW.
(2) The utilization hours of wind farms continued to remain a relatively high level In 2020, the average utilization hours of the Group’s consolidated wind farms were 2,420 hours, representing a decrease of 52 hours as compared with 2019, mainly due to the slight decrease in average wind speed of the regions where the Group’s consolidated wind farms are located as compared with 2019, as well as the increase in the curtailment rate as a result of peak regulation and power rationing in different periods due to COVID-19 outbreak. The Group’s consolidated wind farms realized a power generation of 9,881 million kWh, representing an increase of 11.86% as compared with 2019. The average availability rate of wind power generation units was 98.31%.
(3) Steady progress in wind resources reserves In 2020, the Group’s approved capacity increased by 200 MW and the total approved unstarted project capacity amounted to 1,178 MW. During the Reporting Period, the Group’s wind power projects with a total of 615.8 MW were included in national approved plans. The accumulative capacity of the Group’s wind power projects falling within the national approved plans has reached 7,309.1 MW and its wind power projects are located in 16 provinces across China. During the Reporting Period, the Group’s agreed wind power capacity increased by 3,100 MW across 23 regions including Hebei, Henan, Shandong, Shanxi, Liaoning, Yunnan, Anhui, Gansu, Jiangxi, Jiangsu, Shaanxi, Sichuan, Tibet, Hubei, Hunan, Guangxi, Qinghai, Heilongjiang, Zhejiang, Chongqing, Xinjiang, Inner Mongolia and Jilin.
