Analysis of Wind Power Development in the Third Quarter

A few days ago, the National Renewable Energy Information Management Center released the “Report on the National Wind Power Construction Statistics in the Third Quarter of 2013”.

Newly approved deceleration

According to the report, in the third quarter of 2013, there were 106 newly approved wind farm projects across the country, with an approved capacity of 8.185 million kilowatts, a decrease of 25.3% compared to the same period of last year. Among them, Inner Mongolia and Gansu, which had more approved projects in 2012, consumed the market due to wind power. As a result, the scale of projects approved in 2013 has been significantly reduced. Only Jiangsu has approved three offshore concession wind power projects such as Dafeng 200MW offshore wind power project, Dongtai 200MW offshore wind power project and Binhai 300MW offshore wind power project. The newly approved capacity was the largest in the third quarter, and the newly approved capacity in Shanxi, Hebei, Xinjiang Bingtuan, Shaanxi, and Ningxia increased significantly compared with last year.

As of September 30, 2013, a total of 2,153 wind farm projects have been approved nationwide, with an approved capacity of 123.91 million kilowatts. The three provinces (regions) with the largest cumulative accreditation capacity have been Inner Mongolia, Gansu and Hebei provinces. Among them, the cumulative approved capacity of wind farm projects in Inner Mongolia, Gansu Province, and Hebei Province exceeds 10 million kilowatts.

Added new grid connection

The report pointed out that in the third quarter of 2013, the new grid-connected capacity was 2.75 million kilowatts, and the newly added grid-connected capacity was basically the same as that of the same period of last year. In the third quarter of 2013, the provinces that had more new grid-connected capacity were mainly Inner Mongolia, Jilin, Shanxi, and Xinjiang, among which Inner Mongolia had a new grid-connected capacity of 460,000 kilowatts in the third quarter, ranking first in the country.

As of the end of the third quarter of 2013, the cumulative approved capacity of wind power in the country totaled 123.91 million kilowatts, with a grid capacity of 69.93 million kilowatts. The capacity under construction was 53.98 million kilowatts, and a total of 14 provinces (autonomous regions and municipalities) had more than one million kilowatts of grid connection capacity. In Inner Mongolia, the cumulative capacity of 17.51 ​​million kilowatts is the highest in the country, and Hebei and Gansu ranks second and third respectively with 7.22 million kilowatts and 6.84 million kilowatts.

Winds in some regions have improved

The report also pointed out that in the third quarter of 2013, the total amount of wind power on-grid across the country was 30.3 billion kilowatt-hours, and that of the first three quarters totaled 99.8 billion kilowatt-hours. Due to the fact that most of the regions were in a small wind season in the third quarter, the situation of wind abandonment in the “Three North” region improved slightly. In the third quarter of 2013, the national average equivalent full-load utilization hours was 455 hours, and the rate of abandoned wind was 7.26%. The wind power loss was 2.371 billion kWh, the national average equivalent full-load utilization hours in the first three quarters was 1,514 hours, the wind failure rate was 8.79%, and the power loss due to wind curtailment was 9.618 billion kWh.

The fourth quarter is the windy season. If we estimate the total number of hours of wind power utilization in the fourth quarter of 550-600 hours, it is expected that the equivalent number of full-load hours for wind power will exceed 2000 hours this year, exceeding the 1959 hours last year.

Overall, this year's winds have turned better in various regions, mainly due to several aspects. First, the steady growth of the national load level has stimulated the absorption of wind power. Second, the capacity of thermal power in the Three North region has been Further excavation has increased the proportion of wind power consumption. In addition, the enhancement of transmission grids in local areas also provides strong support for the acceptance of wind power.

The report predicts that by the end of 2013, the nationwide wind power grid capacity will exceed 75 million kilowatts, which is more than 12 million kilowatts of new grid connection capacity at the end of 2012. New grid-connected wind power this year is mainly concentrated in Inner Mongolia, Gansu, Xinjiang, Shandong, and Shanxi. With the construction of large-scale outbound delivery corridors, the issue of wind power restriction will be eased, and the overall national abandonment rate will decrease to a certain extent as compared with last year. However, the problem of wind abandonment in Jilin and Mengdong will still exist.
