(1) Steady growth in installed capacity 

In 2023, the Group added 481.9 MW of wind power installed capacity under management, of which the new consolidated installed capacity was 481.9 MW due to the fact that all the wind turbines of Taian Sanglin, Shuangcheng Phase II, Ruoqiang Luobuzhuang and Zhangbei Zhanhai projects were connected to the grid for power generation. The Group’s accumulative consolidated installed capacity of wind power was 6,293.75 MW, and its accumulative installed capacity under management was 6,554.35 MW. The additional attributable installed capacity of wind power was 419.36 MW, and its accumulative attributable installed capacity was 5,878.71 MW. During the year, the commercial operation project capacity increased by 130.1 MW, and its accumulated commercial operation project capacity was 5,791.55 MW. As at 31 December 2023, the total designed capacity of the wind power projects under construction of the Group was 574.5 MW. Chongli Maniba Wind Farm Project won the 2023 Hebei Province Construction Engineering Anji Cup Award (Provincial Quality Engineering).

(2) The utilization hours of wind farms remained at a relatively high level 

In 2023, the average utilization hours of the Group’s consolidated wind farms was 2,419 hours, a decrease of 66 hours as compared with the same period of the previous year, which was 194 hours higher than the national wind power utilization hours announced by the China Electricity Council. The decrease in average utilization hours was mainly due to the decrease in average wind speed. The consolidated wind farms of the Group achieved the power generation of 14,081 million kWh, representing a year-on-year increase of 0.35%, which was mainly attributable to the contribution from newly commissioned projects, with an average wind turbine availability rate of 97.72%.

 (3) Accelerating wind resource reserves 

In 2023, the Group added 1,441.75 MW of new approved wind power capacity, including the capacity from the entrusted management of the controlling shareholder’s 500 MW wind power project in Zhangjiakou area, with a cumulative total of 2,957.8 MW of approved project capacity yet to be commissioned. An additional 2,591.75 MW of wind power projects were included in the government’s development and construction program, and the Group’s cumulative capacity included in the development and construction programs of various regions reached 10,740.85 MW, which are located in 16 provinces in China, including Hebei, Inner Mongolia, Heilongjiang, Xinjiang, Yunnan, Shanxi and Jiangsu. During the Reporting Period, the Group added 9,231.25 MW of agreed wind power capacity, totalling 32,481.25 MW of effective agreed wind power capacity, which are located in 19 provinces including Hebei, Heilongjiang, Xinjiang and Inner Mongolia.
