　　Energy security is crucial to the national economy and people's livelihood, and cannot be ignored as the 'great concern of the country'. In June 2014, General Secretary Xi Jinping proposed a new energy security strategy of "Four Revolutions and One Cooperation", which clarified the strategic direction of China's energy development and provided fundamental guidance for the overall high-quality development and high-level security of energy in China. Over the past 10 years, as a super large state-owned key backbone enterprise related to national energy security and the lifeblood of the national economy, the State Grid Corporation of China (hereinafter referred to as the "State Grid") has thoroughly implemented the new strategy of energy security, unswervingly promoted the revolution in energy consumption, energy supply, energy technology, and energy system, deepened international cooperation, firmly put the job of energy in its own hands, and better supported and served Chinese path to modernization.

　　1、 The new strategy for energy security has been proposed, and China's power industry has achieved historic achievements in the past 10 years

　　Energy security is a global and strategic issue related to the economic and social development of a country. Since the proposal of the new energy security strategy, the past 10 years have used excavatorbeen a period of significant achievements in China's energy and power infrastructure construction, with the fastest green and low-carbon transformation speed, the highest quality of safe and efficient development, the most significant technological innovation achievements, and the widest range of international power cooperation. At present, China's installed capacity of power generation, new energy, transmission line length, substation capacity, power generation, and electricity consumption remain the world's largest, and the power industry has gone through an extraordinary journey in forging ahead.

　　In the past 10 years, we have vigorously promoted the energy consumption revolution and effectively ensured that the people have access to and use electricity effectively. The green and low-carbon development of energy is related to the future of humanity. To promote the energy consumption revolution, it is necessary to curb unreasonable energy consumption, and work together to promote carbon reduction, pollution reduction, green expansion, and growth. China is deepening the electrification of terminal energy consumption, with a clean heating rate of 76% in northern regions, contributing more than one-third to improving air quality. We will promote the substitution of electricity according to local conditions, and the proportion of electricity in China's terminal energy consumption will reach about 28%. In the past 10 years, the total electricity consumption in China has increased from 5.3 trillion kilowatt hours to 9.2 trillion kilowatt hours, with an average annual growth rate of 5.6%, which has strongly supported an annual economic growth rate of over 6%. State Grid has built the world's most widely covered smart car networking platform, with over 510000 charging stations that can be started and stopped, and more than 25 million registered users. Deeply implementing the "Double Satisfaction" project in Fujian, pushing energy efficiency bills to 117000 households and providing comprehensive energy-saving and carbon reduction solutions.

　　In the past 10 years, we have comprehensively promoted the energy supply revolution and achieved the generation and supply of green electricity. China's ability to independently guarantee energy and electricity continues to improve, and a multi wheel drive energy and electricity production system has been basically formed. Deepen the adjustment of power supply structure and continuously increase the "green content". By the end of 2023, China's installed power generation capacity will reach 2.92 billion kilowatts, and the total installed capacity of renewable energy such as hydropower, wind power, and solar power will reach 1.47 billion kilowatts, accounting for more than 50% of the total installed power generation capacity and historically surpassing the installed capacity of thermal power. Among them, the installed capacity of wind power and solar power has increased by about 5 times and 40 times respectively compared to 2013. Continuously improving the grid structure and building a strong "artery" of the power grid.
