China’s Zero-Coal Power System Future

Abstract

Facing the challenges of climate deterioration, environmental pollution, and energy shortages, China has put forward the goals of “carbon dioxide peaking and carbon neutrality”, and the electricity sector will be the key area and the main direction of carbon emissions reduction. To prospect China’s power system and explore the potential for establishing China’s zero-coal power system in the future, this paper proposes a forecasting-test framework for long-term power system planning. We predict, evaluate, and analyze China’s power system from 2025 to 2060 using the proposed forecasting-test framework. During this process, the power capacity mix and the electricity generation mix of China’s power system will gradually transition from coal-fired generators dominated to wind and solar generators dominated. Moreover, the roles of different generators and energy storages are illustrated through the seasonal comparison and sensitivity analysis of the installed capacity of generators. The results indicate that coal-fired generators can be completely withdrawn from the power system, confirming the feasibility and possibility of achieving China’s zero-coal power system by 2060. Although the timing may be advanced or delayed in different scenarios, achieving China’s zero-coal power system will require exercising nationwide planning and making joint efforts of various sectors from now on.
