摘要

影响我国电力供需的不确定因素日益增多，研判2021年电力供需形势对于保障我国经济社会平稳健康发展具有重要意义。为此，梳理了影响2021年我国电力需求、电力供应的主要因素，从国际经济、国内经济、重点行业、气候气温、电能替代等方面分析了对电力供需的影响；对2021年我国经济走势、电力需求、电力供应进行了预测，并在此基础上综合研判全国及各区域电力供需形势。预计2021年我国全社会用电量将达到8.22万亿kW·h，增速显著反弹；2021年底，全国发电装机容量将达到23.7亿kW，其中新能源装机占比有望超过1/4；2021年我国电力供需形势总体平衡，华中等部分地区用电高峰时段可能存在电力供需紧张。

Abstract

There are more and more uncertain factors affecting the power supply and demand situation in China. Studying and judging the power supply and demand situation in 2021 is of great significance to ensure the stable and healthy development of China's economy and society. Therefore

this paper combed the main factors affecting China's power demand and power supply in 2021

and analyzed the impact on power supply and demand from the aspects of international economy

domestic economy

key industries

climate and temperature

and power substitution. The economic trend

power demand and power supply of China in 2021 were forecasted

and on this basis

the national and regional power supply and demand situation were comprehensively studied and judged. It is estimated that the power consumption of the whole society in China will reach 8.22 trillion kW·h in 2021

and the growth rate will rebound significantly. By the end of 2021

the installed capacity of power generation in China is expected to reach 2.37 billion kW

of which the installed capacity of new energy is expected to account for more than 1/4. Moreover

the power supply and demand situation of China will be generally balanced in 2021

and there may be power supply and demand tension during peak hours in Central China and other regions.
