The proportion of coal power is so high that the installed capacity of coal power accounts for 73% of the total installed capacity, and the generation volume of coal power is 1,807TWh, accounting for 83% of the total generation volume. 煤电的比例非常高，占总装机容量的73％，发电量为1,807 TWh，占总发电量的83%。 Tera: 1012 TWh: Tera Watts hour The features of China’s energy structure determine such a power mix with coal power as the major component. The coal resources in China account for 11% of the world’s total coal reserves, and oil and natural gas account for 2.4% and 1.2% of the total reserves respectively. During a relatively long period in the first three decades of the 21st Century, the primary energy mix with coal playing a dominant role will not be changed. 中国能源结构的特点决定了煤电在电能中的主导地位。中国的煤储量占世界总储量的11%，油和天然气分别占总储量的2.4%和1.2%。在21世纪初很长一段时间内，煤占主导的主要能源结构不会发生变化。 Power supply and demand Power supply and demand Power supply and demand Power supply and demand China’s power market has been facing shortage since 2002, there were curtailments in the peak period in some provincial grids. 从2002年开始，中国的电力市场就面对电能短缺的局面，在某些省网（或省份）发生用电高峰时期拉闸限电。 Peak period, peak hour 用电高峰 Peak load（峰荷），base load（基荷） The shortage also led to an overall delay in the opening of on-grid price competition in wholesale market. 另外，电能短缺也全面推迟了在电能批发市场实行竞价上网。 After the power surplus i
