Under the circumstance of “no standards, no experience, and no equipment” in the world, my country’s UHV has successfully realized the transformation from “starting from scratch” to “great power”, from “created in China” to “led by China”, and from “equipment of China” to “Equip the World”. It can be said that the construction of UHV power grid is the most difficult, innovative and challenging major achievement in the history of my country’s power development, and it is also an important milestone in the development of China’s and even the world’s power industry.
Under the background of carbon peaking and carbon neutrality, the UHV power grid has become the energy transportation “artery” of China’s “West-to-East Power Transmission, North-South Power Supply, Water and Fire Mutual Assistance, and Wind and Solar Complementary”, which has cracked the development of energy and power. The deep-seated contradiction of energy has realized the fundamental transformation of energy from on-site balance to large-scale allocation, which has effectively promoted the clean and low-carbon transformation.
As of the end of 2020, China has completed a total of 35 UHV projects with “14 AC and 16 straight” and “2 AC and 3 straight” under construction, with a total length of 48,000 kilometers of UHV lines in operation and under construction.
“Now that the UHV operation has been successful, people say that I am the ‘father of UHV’, I think it should be the ‘ultra-high pressure’, the winner or the loser. For so many years, I have made myself scarred by insisting on the ultra-high pressure. , who can you tell me about these.” Liu Zhenya, former chairman of State Grid Corporation of China and chairman of the Global Energy Internet Development Cooperation Organization, said with emotion.
In the future, the construction of the global energy Internet with UHV as the backbone network will promote the development of global clean energy bases, the interconnection of power grids in all continents and countries, and promote the integrated development of the “three networks” of energy network, transportation network, and information network, and solve resource shortages and environmental problems. Global challenges such as pollution, climate change, poverty and diseases have opened up new paths and made new contributions to the sustainable development of human society.

“Bright move” on the minibus
At the end of 2004, Liu Zhenya, who had been at the helm of the State Grid Corporation for two months, and the then main leader of the National Development and Reform Commission attended the Three Gorges-Guangdong HVDC project acceptance summary meeting. On the speeding minibus, Liu Zhenya was deeply worried when talking about the current situation of power shortage in China. The domestic power supply has “seriously hindered economic development”.
