The recent news that the State Grid Corporation in the next 5--10 years, network planning, it is proposed to develop long-range, high-capacity transmission technology, plans to build east and west of UHV power grid, and the eastern and western power grid network in order to optimize the allocation of resources, promote saving efficiency, and ultimately the formation of a unified national grid.

Our long-term energy supply and consumption of coal-based coal combustion sulfur dioxide, nitrogen oxides, carbon dioxide and dust emissions are a major source of air pollution; plus energy origin and demand imbalance in the earth, coal resources concentrated in the northwest region demand for energy concentrated on the coast, the central region of the Beijing-Tianjin Tanghe. First, it leads to the development of China's power to provincial (district) self-balancing based, where the need for electricity on where to build the plant; the second is the development and utilization of fossil energy in the process of the destruction of the global environment, the adverse effects of climate change can not be ignored . To improve air quality and the environment, to further control the construction of coal-fired units, receiving area outside the large-scale call request is extremely urgent.

The UHV is currently the world's most advanced transmission technology, long-range, high-capacity, low loss, small area of ??the comprehensive advantages, more secure, more efficient and more environmentally friendly energy configuration is to achieve intensive development of energy resources, promoting clean energy development, an important carrier of an effective solution to the haze problem. In particular, China UHV technology has matured, has built more than UHV AC and DC work, has maintained safe and stable operation fully verified UHV safety, economy and environment friendly features. With leading edge technology and professional management, give full play to the UHV AC, DC, high-capacity, long-range, multi-function placement and network advantages, to achieve the "Made in China" and "China leading the" confidently welcome the world attention.

Thus, adhering to the CPC Central Committee proposed innovation, coordination, green, open, shared development concept, closely "electricity instead of coal, electricity instead of oil, electricity from afar, come clean power" theme, we should speed up construction of UHV power grid construction, promote the development of large-scale energy, improve power grid wide range of optimal allocation of capacity, power resources to achieve interoperability, boosting air pollution control, services, rapid economic and social development needs.
