Recently, the "Statistical Evaluation Report on China's Wind Power Construction in the First Half of 2013" (hereinafter referred to as the "Report") was issued. According to the “Report”, although the newly-added capacity of grid-connected wind power continued to decline in the first half of 2013, the amount of wind power on-grid electricity has increased significantly. Disadvantages are still serious, but they have slightly improved compared to the same period in 2012.

"Twelfth Five-Year" completed more than half of grid-connected installed capacity
The "Report" summarizes the approval of wind power in China in the first half of 2013. As of June 30, the cumulative approved capacity of wind farms nationwide was 116 million kilowatts, with a cumulative grid-connected capacity of 67.49 million kilowatts and a capacity of 48.23 million kilowatts under construction.

In the first half of 2013, 102 wind power projects were newly approved across the country, with newly approved capacity of 9.02 million kilowatts, up 4% year-on-year. Among them, Xinjiang's newly approved capacity exceeds 2 million kilowatts, ranking the first in the country; Shanxi, Gansu's newly added approved capacity exceeds 1 million kW, ranking second and third in the country.

According to the "Report," we can see that more than half of the "Twelfth Five-Year Plan" period has achieved more than half of our target for completing the "12th Five-Year Plan" wind power grid-connected installed capacity.

According to the data, as of June 30, the nation’s new grid-connected capacity was 4.83 million kilowatts in the first half of the year, and in 2012, the accumulated installed capacity of wind power in China was 61 million kilowatts. The installed capacity of grid-connected wind power in China has reached 65.83 million kilowatts. According to the "12th Five-Year Plan for Wind Power Development" issued by the National Energy Administration, by 2015, the cumulative installed capacity of wind power in the country will reach 100 million kilowatts, and more than half has been completed.

However, compared with the data for the same period in 2012, it can be seen that in the first half of 2013, the growth of installed capacity of wind power in the country slowed down by about 39% year-on-year. Among them, Inner Mongolia's wind power interconnection capacity exceeded 17 million kilowatts, leading the country; Hebei, Gansu, Liaoning, Shandong, Jilin, Heilongjiang, Xinjiang, Ningxia, Jiangsu, Shanxi, Yunnan, Guangdong, Fujian and other 14 provinces (autonomous regions, municipalities) and The network capacity also exceeds 1 million kilowatts.

According to Yi Yuechun, deputy chief engineer of the Hydropower and Water Conservancy Planning and Design Institute, the new grid-connected capacity of wind power in the first half of 2013 decreased more than that in the same period of 2012, mainly due to the following reasons. “First of all, there is a large gap in funding for renewable energy subsidies and there is a lot of pressure on companies.” He said frankly that in recent years, with the rapid expansion of the scale of renewable energy, there has been a shortage of funds for renewable energy subsidies. Affected by the current financial environment, subsidy funds, and over-expansion of enterprises, various wind power investment companies have experienced problems such as difficulty in capital turnover and losses, which have slowed investment rates.

Second, the approval authority for wind power is decentralized, and new management models need to be introduced. In May 2013, wind power investment approval authority was decentralized to the local energy authorities. New management methods are being developed in succession. Some wind power investment companies need time to absorb new management methods and explore new management models. This is to some extent Slow wind power construction speed.

"Rejection of Wind" has a slight turn for the better

The "Report" also disclosed key data such as newly added hoisting capacity of wind power, wind power on-grid electricity, and operation of wind farms in the first half of 2013.

According to the data, in the first half of 2013, the newly installed capacity of wind power in China was 6.93 million kilowatts, mainly in Xinjiang, Shanxi and Shandong. However, in the first half of 2013, Beijing, Tianjin, Henan, Hainan, and Tibet (the autonomous regions and municipalities directly under the Central Government) did not install new wind turbines.

In the first half of 2013, the total amount of wind power on-grid across the country was 69.5 billion kwh, an increase of 48% year-on-year, accounting for approximately 2.8% of the nation’s total on-grid electricity. According to the replacement of 320 grams of standard coal per kilowatt-hour of electricity, approximately 22 million tons of standard coal can be replaced. Among them, Mengxi’s grid-connected electricity accounts for approximately 8% of the total grid-connected electricity in Mengxi; the northeastern region’s grid-connected electricity accounts for approximately 9.8% of its total grid-connected electricity, and wind power has begun to play an increasingly important role in energy supply. effect.

The "Report" shows that in the first half of the year, the equivalent utilization hours of national wind farms were 1059 hours, an increase of about 70 hours compared with the same period of last year. Among them, the equivalent utilization hours of Yunnan Wind Farm was 1,385 hours, which was the highest in the country and decreased by about 40 hours year-on-year; followed by Xinjiang, which was 1,207 hours, an increase of approximately 300 hours; Jilin, the lowest, was 835 hours, an increase of approximately 100 hours. In addition, in the first half of the year, the nation’s power supply due to power curtailment caused 7.7 billion kilowatt-hours of power loss, and the nation’s “abandoned winds” rate was approximately 10%, which was approximately two percentage points lower than in 2012.

Yi Yuechun concluded: “Since the country’s electric power load has increased by a certain amount, the capacity for absorbing wind power in the provinces has been enhanced. At the same time, the state’s power grid department has in-depth excavated the peaking capacity of thermal power and effectively increased the hours of wind power utilization, plus 2013 In the first half of the year, newly added grid-connected capacity decreased by 39% year-on-year, and the newly-increased pressure on wind power consumption eased. As a result, the number of hours of wind power utilization in the country in the first half of this year has increased significantly, and the level of wind curtailment has slightly improved.
