Abstract: To fight against climate change, countries around the world are accelerating the energy transition. General Secretary Xi Jinping put forward the “four revolutions, one cooperation” new strategy for energy security and the “carbon emission peaking, carbon neutrality” vision, demanding all efforts to promote high-quality energy development. They will have a profound impact on China’s electric supply and demand pattern. Firstly, this paper refines the connotation and characteristics of high-quality energy development. Secondly, we make the judgment about the transformation direction of the power industry from the perspectives of electric demand, electric supply, technology and market. Finally, through the construction of a multi-regional “energy–economy–power” model system, we analyze the evolving tendency of electric supply and demand pattern from the aspects of electric demand, electric supply, trans-regional power flow, power system pattern, and power market transaction.

Key words: high-quality energy development, electric supply and demand pattern, power system pattern, evolving tendency, electricity market
