Wind Power Business

1. Business review of wind power business (1) Stable growth of installed capacity In 2018, the Group’s consolidated installed capacity of wind power was increased by 509.8 MW, and its accumulative consolidated installed capacity was 3,858.15 MW; its attributable installed capacity of wind power was increased by 458.85 MW, and its accumulated attributable installed capacity was 3,482.75 MW. The Group’s commercial operation project capacity during the year was increased by 384.5 MW, and its accumulated commercial operation project capacity was 3,262.85 MW. As of 31 December 2018, the total designed capacity of the onshore wind power projects under construction of the Group was 659.3 MW, and the total designed capacity of the offshore wind power projects under construction of the Group was 104 MW.

(2) Increase in the utilization hours of wind farms In 2018, the average utilization hours of the Group’s controlled wind farms were 2,482 hours, representing an increase of 90 hours as compared with 2017, and 206 hours more than the average utilization hours in Hebei Province, mainly due to the improvement in the restriction on the use of electricity of the Company in general. In 2018, the Company’s wind curtailment rate was 5.43%, representing a decrease of 2.39 percentage points as compared with 2017. Newly operated wind farms of the Group had good performance, thus the wind energy conversion efficiency was improved, and resulted in higher utilization hours. The Group’s controlled wind farms realized a power generation of 7.676 billion kWh, representing an increase of 13.93% as compared with 2017. The average availability rate of the wind power generation units was 97.97%.

(3) Acceleration in the promotion of wind resources reserves In 2018, the Group’s approved capacity was increased by 663.5 MW and the total approved unstarted project capacity amounted to 2,473.6 MW. During the reporting period, the Group’s wind power projects with a total of 234.5 MW were listed as national approved plans. The accumulative capacity of the Group’s wind power projects falling within the national approved plans has reached 6,633.3 MW and its wind power projects are located in more than 10 provinces across China. During the reporting period, the Group’s new wind power agreed capacity was increased by 4,230 MW across 22 regions including Hebei, Henan, Shandong, Shanxi, Liaoning, Yunnan, Anhui, Gansu, Jiangxi, Jiangsu, Shaanxi, Sichuan, Tibet, Hubei, Hunan, Guangxi, Qinghai, Heilongjiang, Zhejiang, Chongqing, Xinjiang and Inner Mongolia.

(4) Continuous improvement in operation and maintenance management In the benchmarking of wind power industry in Northern China for the year 2017 by China Electricity Council, 2 wind farms owned by the Group were graded 5A, 1 wind farm was graded 4A and 3 wind farms were graded 3A. In addition, the Group won the Benchmarking First Prize in Zhangjiakou in Hebei Province for the second time.
