On 30 April 2026, the China National Institute of Standardization (CNIS) issued a call for data collection to support the development of three national standards initiated in 2025. These standards fall under SAC/TC20 (Energy Fundamentals and Management), for which CNIS serves as secretariat.

The standards comprise one mandatory national standard (GB) and two national standardization technical guiding documents (GB/Z):

GB Standard:

20253197-Q-469 Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Communication Base Stations

GB/Z Standards:

20256785-Z-469 Technical Requirements and Test Methods for Energy Efficiency Evaluation of Telecommunication Equipment for Telecommunication Base Stations

20256265-Z-469 Technical Requirements and Test Methods for Evaluation of Computing Power, Energy Efficiency, and Carbon Efficiency of Data Centers

For the GB standard on communication base station energy efficiency, CNIS is soliciting measured data on enterprise base station quantities across climate zones, annual energy consumption distributions, and testing methods and improvement recommendations for base station energy efficiency.

For the GB/Z standard on telecommunication equipment energy efficiency, the focus is on energy consumption and energy-saving functions of core communication equipment for 5G and 4G base stations, including power consumption per unit carrier frequency under different loads classified by channel count, alongside testing methods and improvement recommendations.

For the GB/Z standard on data center efficiency, CNIS is collecting information on server types, theoretical computing power, and energy efficiency levels for general-purpose, intelligent computing, and super computing data centers, as well as mainstream training models and energy-saving technologies for intelligent computing equipment, plus testing methods and improvement recommendations for computing power, energy, and carbon efficiency.

The data collection reflects a practical step in standards development, ensuring the final requirements are grounded in actual industry performance rather than theoretical benchmarks. For European stakeholders, the process offers a window into how Chinese standards are formulated and an opportunity to contribute technical insights during the formative stage. SESEC will track the progress of these three standards and report on their advancement through SAC/TC20.
