It is currently the highest-altitude UHV direct current power transmission project in the world. State Grid said the project will pass through four provincial regions: Tibet, Sichuan, Chongqing and Hubei. The Tongshan pumped-storage hydropower station will be equipped with four sets of power generators, each with a capacity of 350,000 kilowatts.
During the “Twelfth Five-Year Plan” and “Thirteenth Five-Year Plan” periods, to adapt to the rapid development of new energy and UHV power grids, pumped storage power stations such as Fengning in Hebei Province and Jixi in Anhui Province ushered in a new peak.

"Therefore, if there isn't enough wind and solar power when a line is expected to operate, it will send coal power instead," says Shen Xinyi, a researcher at CREA. Because wind and solar power is intermittent, UHV lines still rely heavily on coal or gas-fired power to ensure that their transmission is stable, Shen notes.
UHV lines operate at a voltage level of 765kV in India. Cross-continental high-voltage projects – which run at voltage levels lower than those of UHV – are also on the drawing board in various parts of the world. In Europe, several undersea cables are being developed to bring solar and wind power from North Africa.
Analysis of the investment composition proportion of two pumped storage power stations in the Central China region. According to Table 6, the total investment required to construct a pumped storage power station is approximately 9 billion yuan. The static total investment of the project accounts for about 82 % of the total investment.
