On October 30, 2020, the National Energy Administration held an online press conference for the fourth quarter to announce the national energy production and consumption situation, the grid-connected operation of renewable energy, and the power supply reliability index for users in 50 major cities across the country.


Energy consumption rebounded, energy supply is strong and effective


In the first three quarters of this year, the National Energy Administration adhered to the guidance of Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era, thoroughly implemented the decisions and deployments of the Party Central Committee and the State Council, did a solid job of "six stability" and fulfilled the tasks of "six guarantees", and normalized Do a good job in energy development and reform in the prevention and control of the epidemic, and promote high-quality energy development. On the whole, energy production and consumption have gradually picked up, and the supply and demand of coal, electricity, oil and gas have been connected smoothly and orderly, providing strong support for epidemic prevention and control and economic and social stability.


1. National energy production and consumption is gradually picking up


1. From the consumption side, in the third quarter, domestic consumption demand continued to recover, which led to an overall rebound in energy consumption. Electricity consumption has grown rapidly, and the cumulative annual electricity consumption has exceeded the same period last year. During the "peak summer" period, many provinces (autonomous regions and municipalities) reached new highs in electricity load, and the national maximum electricity load increased by about 24 million kilowatts compared with last year. The cumulative electricity consumption in the first three quarters increased by about 1.3% year-on-year, and the growth rate increased by 2.6 percentage points from the first half of the year. In terms of industries, the growth rate of power consumption in the secondary industry has increased steadily since April. The growth rate of power consumption in August and September reached 9.9% and 8.6%, and the contribution rate to the growth of electricity consumption reached 83% and 75%. The main force in the growth of electricity consumption; the growth rate of electricity consumption for primary production has been maintained at a relatively high level under the promotion of various policies for strengthening farmers and benefiting farmers. The quarterly growth rate was 6% year-on-year; the tertiary industry's electricity consumption has continued to increase since May, and the growth rate reached 7.5% in August, a new high this year. The cumulative decline in the first three quarters was 0.2% year-on-year, and the rate of decline narrowed by 3.8 percentage points from the first half of the year. Natural gas consumption has grown steadily. Since March, monthly consumption has maintained a positive growth, and the growth rate has increased quarter by quarter. The consumption of refined oil gradually picked up. Resident travel increased, transportation and infrastructure oil consumption continued to steadily rebound, gasoline and diesel consumption continued to improve, and the year-on-year growth rate of refined oil consumption in the third quarter increased by about 12% compared with the second quarter.


2.
