Spanish media: Ultra-high voltage technology is reshaping China's energy map
The Spanish newspaper "El País" website recently published an article stating that in order to ensure the grid connection of renewable energy, China is focusing on building ultra-high voltage transmission systems and promoting the interconnection of the national power grid.

The article gives an example that in the Ningxia Hui Autonomous Region, a power line crosses mountains, plateaus and valleys, directly reaching the industrial hub of Hengyang in Hunan Province. Currents surge along more than 1,600 kilometers of cables and towers, which is precisely the ultra-high voltage direct current channel used by China to ensure grid security and reshape the energy landscape. During the effort to promote ecological transformation, this technology is reshaping China's energy map.
The article noted that the project has a rated capacity of up to 80 million kilowatts, and can deliver about 2.747 billion kilowatt-hours of green electricity annually, enough to meet the annual electricity needs of about 980,000 households. During the transmission process, the power loss over 1,000 kilometers is significantly reduced compared to traditional power grids.

The article cited data stating that in the past five years, the length of China's ultra-high voltage direct current lines increased from 28,000 kilometers to more than 40,000 kilometers. As of now, China has built 1 ±1100 kV, 23 ±800 kV, and 21 1000 kV ultra-high voltage lines.

The article analyzed that China has become the country with the fastest pace of energy transition in the world and has achieved its 2030 target for wind and solar power generation capacity six years ahead of schedule. In order to improve transmission efficiency, China chose to build a power transmission system centered around ultra-high voltage grids, enabling it to redistribute power flow according to demand. Industry insiders believe that this cross-regional scheduling optimizes the utilization of renewable energy by reducing reliance on individual regions and enhancing coordination between different power grids, thus improving corporate energy efficiency.
