Ultra-high-voltage electricity transmission (UHV electricity transmission) has been used in China since 2009 to transmit both alternating current (AC) and direct current (DC) electricity over long distances separating China's energy resources and consumers.
Compared with high voltage (HV) transmission technology, UHV power transmission has the advantages of large transmission capacity, long transmission distance, and low line loss (Liu 2015). The Jindongnan-Nanyang-Jingmen UHV transmission line is the first UHV alternating current transmission project in China.
UHV refers to voltage levels with direct current over ±800 kV and alternating current over ±1000 kV. Compared with high voltage (HV) transmission technology, UHV power transmission has the advantages of large transmission capacity, long transmission distance, and low line loss (Liu 2015).
To some researchers, UHV brings obvious benefits. "Of all existing technologies, UHV is the only one that can send wind and solar power from far-flung areas to load centres (places with high electricity consumption)," says Fang Lurui, an assistant professor of power-system planning at Xi'an Jiaotong-Liverpool University in Suzhou, China.
Power is transmitted through UHV projects from cities with plentiful power resources to those with big power consumption gap, such as Beijing, Tianjin, or other cities. They change the energy consumption pattern between cities and play a key role in solving the power shortage, which may have a potential impact on regional carbon emissions.
China defines those sending direct currents (DC) at voltage levels of 800 kilovolts (kV) or above and alternating currents (AC) at 1,000 kV or above as UHV links. DC systems can carry more power with less loss than AC, and are used to cover greater distances, but they are more expensive to build.

Ultra-high-voltage electricity transmission (UHV electricity transmission) has been used in China since 2009 to transmit both alternating current (AC) and direct current (DC) electricity over long distances separating China''s energy resources and consumers. Expansion of both AC and DC capacity continues in order to match generation to consumption demands while minimizing transmission losses. Decarbonization improvements will result from the replacement of lower effic…
