In February 2022, China began construction of national computing power hub nodes in eight regions, including Beijing-Tianjin-Hebei, the Yangtze River Delta, the Guangdong-Hong Kong-Macao Greater Bay Area, Chengdu-Chongqing, Inner Mongolia Autonomous Region, Guizhou Province, Gansu Province, and Ningxia Hui Autonomous Region, and planned to build 10 national data center clusters. In order to further optimize the deployment of production capacity and fully utilize the energy advantages of the western region, the “East to West Computing” project has been fully launched. As of the end of March this year, the computing capacity of the 10 national data center clusters exceeded 1.46 million racks (19-inch standard racks), and the overall utilization rate was 62.72%, up 4 percentage points from 2022. The network latency between the east and west hub nodes almost meets the requirement of 20 milliseconds. The proportion of green electricity used by data centers exceeds the national average, with the green electricity usage rate of some advanced data centers reaching about 80%, and the power usage effectiveness (PUE) of newly built data centers has fallen to as low as 1.10.
