The overall balance of power supply and demand across the country
In 2020, the electricity consumption of the whole society will be 7.51 trillion kWh, a year-on-year increase of 3.1%. During the "13th Five-Year Plan" period, the electricity consumption of the whole society will grow at an average annual rate of 5.7%. In 2020, the growth rate of electricity consumption in the whole society in each quarter will be -6.5%, 3.9%, 5.8%, and 8.1% respectively. The steady recovery of economic operation is the main reason for the rebound in electricity consumption growth. CEC stated that the quarterly growth trend of electricity consumption throughout the society reflects that as the epidemic is effectively controlled and the country's countercyclical control policies are gradually implemented, the resumption of work and production, the resumption of business and the market have continued to achieve significant results, and the national economy has continued to stabilize recover.

The investment in power grids of 35 kV and below, which accounted for 44.3% of power grid investment, dropped by 20.2% year-on-year.
The proportion of non-fossil energy installed capacity increases
The proportion of coal-fired power installed capacity in total installed capacity fell below 50% for the first time, and the scale of new grid-connected wind power installed capacity hit a record high. In 2020, the nation’s new installed capacity of power generation will reach 190.87 million kilowatts, a year-on-year increase of 85.87 million kilowatts. The newly added grid-connected wind power and solar power installed capacity will be 71.67 million kilowatts and 48.2 million kilowatts, respectively. . By the end of 2020, the country’s full-caliber hydropower installed capacity was 370 million kilowatts, thermal power 1.25 billion kilowatts, nuclear power 49.89 million kilowatts, grid-connected wind power 280 million kilowatts, and grid-connected solar power installed capacity of 250 million kilowatts.

The overall balance trend remains unchanged
The China Electricity Council stated that 2021 will be the first year of my country's implementation of the "14th Five-Year Plan" and the beginning of the new journey of building a modern socialist country in an all-round way.
The report predicts that in 2021, the newly installed power generation capacity of national infrastructure will be about 180 million kilowatts, of which the installed capacity of non-fossil energy power generation will be about 140 million kilowatts. It is estimated that by the end of 2021, the installed capacity of power generation nationwide will be 2.37 billion kilowatts, a year-on-year increase of about 7.7%. The 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 proportion of wind power and solar power installed capacity will increase by about 3% compared with the end of 2020, and the demand for the flexibility of the power system will further increase.
The report predicts that in 2021, the overall national power supply and demand will be balanced, and the power supply in some areas will be tight or even tight during peak hours.
China Electricity Union stated that, as the country is accelerating the construction of a new development pattern with domestic and international double cycles as the mainstay and mutual promotion of domestic and international double cycles, "China's carbon dioxide emissions will strive to reach the peak by 2030, and strive to achieve carbon emissions by 2060. Under the target requirements of "Zhonghe", on the one hand, the power industry must ensure the safe and reliable supply of electricity to meet the national economic development goals and the people’s daily electricity demand; on the other hand, the power industry needs to accelerate the transformation of a clean and low-carbon supply structure to achieve Carbon reduction goals.
