With the aim of supporting the data needs of Beijing and major coastal centres, China is said to have approved plans to build four mega clusters of data centres in the country's north and west.

According to the country's top state planner on Wednesday, the clusters will be built in the northern Inner Mongolia region, northwestern Ningxia region, Gansu province and southwestern Guizhou province.

The National Development and Reform Commission said in four separate statements that the four locations can use their energy and environmental advantages to set up green and low-carbon mega data centres.

The move comes as energy-hungry data centres located in China's east have found it difficult to expand due to limits imposed by local governments on electricity consumption.

Some cities in China's northern and western regions rich in renewable energy resources such as wind and solar power have already built data centres to serve the economically developed coast. But their distant locations have meant the centres have struggled to provide the near-instantaneous retrieval demanded by coastal clients with little tolerance for delays.

It is however unclear how China would turn western and northern regions such as Ningxia and Gansu into actively operating centres of computing power given the data latency caused by the huge distances to data users in the east. These regions are 1,000 km (600 miles) from the coast.

China aims to expand its big data industry into a more than 3 trillion yuan ($470 billion) sector by 2025 through the building of several clusters of data centres, according to a 2021-2025 plan by the Ministry of Industry and Information Technology released in November.
