Since the reform and opening up, the power industry has achieved great development and remarkable achievements. At present, the installed capacity and power supply of China's power industry rank second in the world. China has formed seven inter provincial power grids and five provincial power grids in North China, Northeast China, East China, central China, Northwest China, Sichuan and Chongqing, and the south, including Hong Kong and Macao. Finally, a unified national combined power grid will be formed to realize the optimal allocation of resources and the sustainable development of power in a larger range. At the same time, the power industry is also facing severe challenges. First, the power industry must continue to adapt to the needs of the national economy and the improvement of people's living standards. It must maintain a certain speed of development, adjust the structure in the development, and develop in the adjustment of the structure; Second, the per capita social power supply level in China is still very low. Strengthening the construction and transformation of urban and rural power grids, opening up the power market and reducing the burden on users are still a long-term important task; The third is to adjust the structure, optimize the allocation of resources, speed up regional and national networking, achieve sustainable development, and solve the problems of low efficiency, high coal consumption and serious pollution. The task is arduous. In order to realize the sustainable development of the power industry, we must break the monopoly, introduce competition, establish a standardized and orderly power market, realize "separation of power plants and networks, bidding for access to the Internet", constantly enhance the strength and vitality of enterprises, and improve the service level.

    Electric power industry is mainly used in traditional fields such as living and office, high energy consuming industries and the emerging field of electric vehicle charging. Thermal power is the main way to obtain electric energy. With the depletion of resources and the increasing attention of society to environmental protection issues, the proportion of renewable and new energy power generation is increasing.
