How should China's power companies get rid of wind power and "discard the wind"?

On October 17th, wind power plays a vital role in providing clean energy and supporting environmental sustainability. However, in recent years, the issue of wind curtailment—where wind energy is wasted due to grid limitations—has become increasingly severe in China. This problem has emerged as a major obstacle to the growth of the wind power industry. In response, officials from the National Energy Administration have stated that it will take two to three years to address this challenge effectively. Wind curtailment occurs when wind turbines are operating normally, but they are forced to shut down due to insufficient grid capacity, mismatched timing of wind farm construction, or unstable wind conditions. This situation not only leads to energy waste but also reduces the economic returns for wind power producers. At the 2013 Beijing International Wind Energy Conference, Wang Jun, Director of the New Energy Division at the National Energy Administration, highlighted that by the end of 2013, China's total wind power installed capacity was expected to exceed 75 million kilowatts, with annual generation reaching 140 billion kilowatt-hours. Despite these impressive figures, wind curtailment remains a pressing issue, particularly in certain regions where the problem is more severe. According to the "China Wind Power Development Report 2013," the amount of wind power curtailed in 2012 reached approximately 20 billion kilowatt-hours, doubling from the previous year. This accounted for 20% of the total wind power generated that year. The Three North Region, especially areas like Mengdong and Jilin during winter heating periods, experienced curtailment rates exceeding 50%. Shi Dingyi, President of the China Renewable Energy Society, pointed out that wind curtailment not only harms the profitability of wind power companies but also leads to significant energy waste. This undermines the overall investment and environmental benefits of the wind power sector. The report noted that the challenges in absorbing wind power stem from its intermittent and unpredictable nature. However, deeper causes include the lack of proper integration of new energy sources into the power system and outdated policy mechanisms. In response, Wang Jun emphasized that China is working on improving policies and reforming the power system to ensure priority access for wind power to the grid. In areas with severe curtailment, a renewable energy quota system may be introduced. The goal is to resolve the issue of wind curtailment within two to three years. Looking ahead, Wang Jun stressed the need to enhance the management system for wind power development and optimize regional layouts based on local conditions. With advances in low-speed wind turbine technology, wind power development in central, eastern, and southern China—regions with high electricity demand—has grown significantly, creating new opportunities for expansion. Shi Lishan, Deputy Director of the New Energy Division, suggested expanding the scope of resource planning by enhancing cross-regional electricity transmission. This would allow wind power fluctuations to be better absorbed by larger grids. He also emphasized the importance of rationalizing the energy management system. Currently, different types of energy in China operate in isolation. While electricity cannot be stored, heat can. Balancing power supply and heating is crucial for managing wind power volatility. In addition, Shi Pengfei, Deputy Director of the Wind Energy Professional Committee, recommended that domestic wind equipment manufacturers focus on overseas markets. Chinese manufacturers have competitive advantages such as low costs and diverse product lines, and it is expected that wind turbine exports could reach 1 million kilowatts. Finally, Shi Dingxi noted that while the main market for wind power is still domestic, there is hope for it to expand globally, similar to solar power. Strengthening international cooperation and exploring emerging markets will be essential for future growth.

Building Tempered Glass

Our Building Tempered Glass is specially designed for use in construction and architectural projects, offering exceptional strength and safety. Through a process of controlled heating and rapid cooling, tempered glass becomes up to four times stronger than regular glass, making it ideal for high-stress environments. It is resistant to impact, thermal shock, and breakage, and in the rare event of breakage, it shatters into small, blunt pieces that reduce the risk of injury. Perfect for windows, doors, facades, and partitions, our tempered glass combines durability with sleek design, ensuring both performance and aesthetic appeal in any building structure.
