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.
