West-East Electricity Transmission is a landmark project of the Western Development. The west-to-east power transmission is to convert the energy of the western provinces and regions rich in coal and hydropower resources into power resources, and transport them to the eastern coastal areas where power is scarce.

Hangzhou Qiantang River Converter Station is the first stop of the world's second largest hydropower station - Baihetan Hydropower Station's west-to-east power transmission into Zhejiang. It only takes 7 milliseconds for one kilowatt-hour of electricity to go from Sichuan to Zhejiang, which is short in time, high in voltage, and high in safety requirements. The safe and stable operation of UHV projects is of great significance to promoting China's energy transition to low-carbon and clean energy. According to the relevant plan of China's National Energy Administration, by 2025, China's "West-to-East Power Transmission" capacity will reach more than 360 million kilowatts. Editor / Zhao E
