Annual utilization hours of wind power generation

What are the utilization hours of China's Wind power generation equipment?

Utilization hours refer to the annual power produced, divided by rated power. As can be seen from Figure 4, the utilization hours of China's wind power generation equipment fluctuated to a certain extent, with the lowest point of 1724 h in 2015 and the highest value of 2103 h in 2018.

How many kWh does wind power generate a year?

According to data from the National Energy Administration (NEA) (NEA 2020a), the wind power generation in 2019 was 405.7 billion kWh which accounted for 5.5% of total power generation, and it was the first time for wind generation to exceed 400 billion kWh. In 2019, the average utilization hours of wind power nationwide were 2082 h.

What was the average usage of wind power in 2019?

In 2019, the average utilization hours of wind power nationwide were 2082 h. The issue of wind curtailment and power curtailment had also been further alleviated. In 2019, the curtailment of wind power was 16.9 billion kwh, a year-on-year decrease of 10.8 billion kwh, and the average wind curtailment rate was 4%, a year-on-year decrease of 3%.

How much wind power does China use a year?

The annual generated offshore wind power in China is 7.91 × 10 12 kWh, 2.04 times of the electricity consumption (3.88 × 10 12 kWh) in 11 coastal provinces in 2020. The wind profile data can be accessed from National Climate Center of China Meteorological Administration under reasonable request.

What is the cumulative installed capacity of wind power?

The cumulative installed capacity of wind power accounts for more than one third of the global total. The annual newly installed capacity of wind power accounts for about 56% of the global total. The annual new and cumulative installed wind power capacity since 2005 is shown in Figure 2. Figure 2.

How is China's Wind Power Development based on Data Envelopment Analysis?

On the basis of analyzing the current situation of China’s power development, especially wind power development, a data envelopment analysis (DEA) method was used to analyze China’s wind power development and utilization efficiencies from 2005 to 2020.
