The "Report" predicts that in the second half of the year, the electricity consumption of the whole society will increase by about 6% year-on-year, and the electricity consumption of the whole society will increase by 10%-11% throughout the year. By the end of 2021, the installed capacity and proportion of non-fossil energy power generation are expected to surpass that of coal power for the first time. The country's power supply and demand are generally balanced, and regions with tight power supply will increase over the previous year.
High-tech and equipment manufacturing industries are growing rapidly in electricity consumption
In the first half of the year, the country’s electricity consumption was 3.93 trillion kWh, a year-on-year increase of 16.2%, and an average increase of 7.6% over the two years. The low base formed by the epidemic in the same period last year was the main reason for the rapid year-on-year growth in electricity consumption in the first half of the year. In quarterly terms, the two-year average growth rate of electricity consumption in the whole society in the first and second quarters was 7.0% and 8.2% respectively. The year-on-year growth rate of electricity consumption in the whole society and the two-year average growth rate reflect that my country's economic development is showing steady strengthening and steady improvement.
In the first half of the year, the manufacturing industry's electricity consumption increased by 18.4% year-on-year, and the two-year average growth rate was 7.8%.

Seventh, the growth rate of raw coal production was 8.7 percentage points lower than the growth rate of coal-fired power generation during the same period. The market price of thermal coal increased rapidly in the second quarter. In the first half of the year, the national raw coal output increased by 6.4% year-on-year, which was 8.7 percentage points lower than the year-on-year growth rate of full-caliber coal-fired power generation during the same period; in the first half of the year, cumulative coal imports fell by 19.7% year-on-year. The price of thermal coal in the market rose rapidly in the second quarter, reaching a historical high, making it more difficult to purchase and secure thermal coal. The fuel cost of coal-fired power companies has risen sharply. In June, the unit price of standard coal at the scene of some large power generation groups increased by 50.5% year-on-year. The loss of coal power companies has significantly expanded. In June, some power generation groups lost more than 70% of coal power companies, and the coal power sector suffered a loss as a whole.
The proportion of non-fossil energy power generation capacity is expected to surpass that of coal power generation for the first time
Since the beginning of this year, my country's economy has continued to recover steadily, and the rapid growth of foreign trade exports has driven the demand for electricity consumption to increase more than expected. Taking into account the domestic and foreign economic situation in the second half of the year, the changes in the base number before and after the previous year, the replacement of electric energy, as well as the foreign epidemic situation and the uncertainty of the external environment, the "Report" predicts that the electricity consumption of the whole society will increase by about 6% year-on-year in the second half of 2021. , The electricity consumption of the whole society increased by 10%-11% throughout the year. If there is a long-term and large-scale cold wave in winter, the annual growth rate of electricity consumption in the whole society may exceed 11%. By the end of 2021, the installed capacity and proportion of non-fossil energy power generation are expected to surpass that of coal power generation for the first time.
The "Report" predicts that the national infrastructure construction will add about 180 million kilowatts of installed power generation capacity throughout the year, of which about 140 million kilowatts will be installed for non-fossil energy power generation. It is estimated that by the end of the year, the national installed capacity of power generation is 2.37 billion kilowatts, an increase of about 7.7% year-on-year; among them, coal power installed capacity is 1.1 billion kilowatts, hydropower is 390 million kilowatts, grid-connected wind power is 330 million kilowatts, grid-connected solar power is 310 million kilowatts, and nuclear power is 54.41 million kilowatts. , Biomass power generation is about 35 million kilowatts. The total installed capacity of non-fossil energy power generation reached about 1.12 billion kilowatts, accounting for 47.3% of the total installed capacity, an increase of about 2.5 percentage points from the end of 2020. The scale and proportion of non-fossil energy power generation capacity is expected to surpass that of coal power for the first time.
The "Report" predicts that the overall power supply and demand across the country will be balanced in 2021, and the power supply in some areas will be tight during peak hours, and the power supply will be tight in areas and the extent will exceed the previous year. From the demand side, power consumption demand is expected to maintain rapid growth in the second half of the year. During the peak summer period, high temperature weather will increase the peak-to-valley difference of power load, which will bring greater challenges to system peak shaving. From the perspective of the supply side, the proportion of installed wind power and solar power generation continues to rise, and the lack of flexibility in the power system's period of time adjustment will be further aggravated; the supply of coal in some areas such as the southwest is tight, restricting the power generation capacity of coal-fired power plants; and the supply of natural gas in some areas The tension will affect the peak power generation capacity of the gas turbine.
From the perspective of the balance of supply and demand in various regions, it is expected that the power supply and demand in the central and southern regions will be tight during peak hours, and the situation in the southern region will be particularly severe; the power supply and demand in the north and east regions are basically balanced; the power supply and demand in the northeast and northwest are more than balanced.
