(1) Steady growth of installed capacity
In 2022, the Group’s consolidated installed capacity of wind power increased by 203 MW, of which, the installed capacity is 138MW. A number of projects, such as Fengning Waigoumen Wind Power and Photovoltaic Power Complementation Phase I Project ( 豐寧外溝門風光互補一期項目 ), Hunan Passage Phase II Project ( 湖南通道二期項目 ) and Korla Bailuzhou Decentralized Wind Power Project ( 庫爾勒白鷺洲分散式風電項目 ) were connected to the grid for power generation, with accumulative consolidated installed capacity of 5,811.85 MW, accumulative installed capacity under management of 6,072.45 MW, increased attributable installed capacity of wind power of 170.89 MW, and accumulated attributable installed capacity of 5,482.49 MW. The Group’s commercial operation project capacity during the year increased by 304.1 MW, and its accumulated commercial operation project capacity was 5,667.25 MW.
As of 31 December 2022, total construction capacity of the Group’s wind power projects under construction reached 516.4 MW. The offshore wind power 300 MW demonstration project on Puti Island, Laoting, Tangshan and Kangbao Yongfeng 200 MW wind power project, which are funded and constructed by the Group, won the 2021-2022 China Installation Works Merit Award ( 中國安裝工程優質獎 ) (China Installation Star) ( 中國安裝之星 ), which is the highest honor for engineering quality in domestic installation industry.
(2) The utilization hours of wind farms continued to remain a relatively high level
In 2022, the average utilization hours of the Group’s consolidated wind farms were 2,485 hours, largely remained at the same level as in 2021, and was 264, respectively. The Group’s consolidated wind farms realized a power generation of 14.031 billion kWh, representing an increase of 4.17% as compared with the same period of 2021. The average availability rate of wind power generation units was 98.16%, mainly due to the contribution from newly operating projects.
(3) Accelerated progress in wind resources reserves
In 2022, the Group’s approved capacity increased by 771.5 MW, and the accumulative approved capacity of projects not yet commenced was 2,020 MW. New wind power projects with total capacity of 600 MW were included in the governmental development and construction plans. The Group’s accumulative capacity included in the local development and construction plans of various regions reached 8,149.1 MW, locating in 16 provinces across China, including Hebei, Inner Mongolia, Heilongjiang, Xinjiang, Yunnan, Shanxi and Jiangsu.
During the Reporting Period, the Group’s agreed wind power capacity increased by 14,200 MW and the accumulated agreed wind power capacity was 63,302.5 MW, locating across 19 provinces, such as Hebei, Heilongjiang, Xinjiang and Inner Mongolia.
