About Ultra-high voltage transmission of solar power generation
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.
Since 2004, electricity consumption in China has been growing at an unprecedented rate due to the rapid growth of industrial sectors. Serious supply shortage during 2005 had impacted the operation of many.
UHV transmission and a number of UHVAC circuits have already been constructed in different parts of the world. For example, 2,362 km of 1,150 kV circuits were built in the , and 427 km of 1,000 kV AC circuits have been developed in Japan ( .

On theand side, the country has focused on expanding capacity and reducing losses by: 1. deploying long-distance (UHVDC) and (UHVAC) transmission .
China's focus on UHV transmission is based on the fact that energy resources are far away from the load centers. The majority of theresources are in the west, andis in the northwest, but huge loadings are in the east and south. To reduce transmission.
