Unlocking Demand-Side Flexibility in China
Current Status and Potential of Demand Response in the Industrial SectorDownload the report below
A zero-carbon power system will face uncertainties from both the supply and demand sides. This will require more system flexibility resources to meet the power balance and to realize a larger scale of renewable energy integration. This is especially true in China where the compound annual growth rate of electricity consumption between 2015 and 2022 reached 6.1 percent. The growth rate of the peak load was even higher at 7.1 percent, showing greater volatility on the load side.
With economic development and electrification of other sectors, China’s electricity demand will continue to grow, and the value of demand-side flexibility (DSF) will become increasingly significant. In recent years, the power supply and demand balance in China has been tight and strengthening load management and developing DSF resources have become urgent tasks in building the New Power System.
Why Focus on the Industrial Sector?
The electricity consumption of industrial users in China has reached 5,700 terawatt-hours, accounting for 65 percent of total electricity consumption in 2022, and is still increasing. Considering the comprehensive industrial system and diversified load structure, the industrial sector theoretically possesses significant potential for developing DSF. Our in-depth investigation of the demand response capabilities of different industries and enterprises showed that seven major industries would achieve over 20 percent of demand response capability. Developing this industrial DSF will reduce 3-10 percent of the annual peak load and avoid 40–130 GW of new coal power investment in China. China’s practices in industrial DSF could serve as a model especially for developing countries that are still in the process of industrialization but need to achieve climate goals at the same time.
About This Report
This report dives deep into the technical issues of developing industrial DSF. Combining domestic and international practice and progress, we identify the main sources and potentials of industrial DSF; explore the technical, economic, and managerial challenges; and specify the important role that industrial DSF plays in building the New Power System.
