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

On October 17th, wind power stands as a promising solution that not only supports energy security but also contributes to environmental sustainability. However, in recent years, China has faced a growing challenge: the large-scale abandonment of wind power, which has become one of the most pressing issues hindering the industry's growth. In response, officials from the National Energy Administration have stated that it may take two to three years to effectively address this problem. Wind curtailment occurs when wind turbines are operating normally, yet wind farms must shut down due to limitations in local grid capacity, mismatched construction timelines, or unstable wind conditions. This issue is particularly acute in certain regions, where the integration of wind power into the grid remains a major obstacle. 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 surpass 75 million kilowatts, with annual generation reaching 140 billion kilowatt-hours. Despite these impressive figures, wind curtailment still persists due to inadequate coordination between different power sources and limited grid integration technology. Some areas continue to experience severe curtailment, affecting both economic returns and the overall efficiency of wind power projects. According to the “China Wind Power Development Report 2013,” the nation’s wind curtailment in 2012 reached approximately 20 billion kWh, doubling from the previous year. This accounted for 20% of total wind power generation. The situation was especially severe in the Three North Regions, where winter heating periods saw curtailment rates exceeding 50% in some areas like Mengdong and Jilin. Shi Dingyi, President of the China Renewable Energy Society, emphasized that wind curtailment not only undermines the profitability of wind power companies but also leads to significant energy waste. This inefficiency hampers the long-term investment and environmental benefits of the wind power sector. The report pointed out that the challenges in absorbing wind power stem from its intermittent and variable nature. However, deeper causes include the lack of appropriate power system adjustments and policy mechanisms to accommodate the volatility of renewable energy sources. To tackle this, Wang Jun mentioned that China is working on improving policies and reforming the power system to ensure priority access for wind power. In more severe cases, a quota system for renewable energy could be introduced. The goal is to resolve the curtailment issue within two to three years. Looking ahead, Wang stressed the need to enhance the management system for wind power development and optimize regional layouts. With advancements in low-speed wind turbine technology, wind power has gained momentum in China’s central, eastern, and southern regions, where electricity demand is high, creating new opportunities for growth. Shi Lishan, Deputy Director of the New Energy Division, suggested expanding the scope of resource planning, including cross-regional power transmission, to better absorb wind fluctuations across a larger grid system. He also emphasized the importance of rationalizing the energy management system. Currently, various energy sources in China operate in isolation. While electricity cannot be stored easily, heat can. Coordinating power supply with heating systems is crucial for managing wind power volatility. In response to shrinking domestic demand, Shi Pengfei, Deputy Director of the Wind Energy Committee, recommended that Chinese wind equipment manufacturers focus on international markets. With cost advantages and diverse product offerings, China's wind industry is well-positioned to expand overseas, with expectations of exporting over 1 million kilowatts of wind turbines. Finally, Shi Dingxi noted that while the main wind power market is still domestic, there is hope for wind power to follow the same global trajectory as solar energy. Strengthening international cooperation and exploring emerging markets will be key to achieving this vision.
