CHINA HAS MORE THAN 3.8 MILLION 5G BASE STATIONS
New modular designs enable capacity expansion through simple container additions at just $210/kWh for incremental capacity. These innovations have improved ROI significantly, with
Ye G. Research on reducing energy consumption cost of 5G Base Station based on photovoltaic energy storage system. In: 2021 IEEE International Conference on Computer Science, Electronic Information Engineering and Intelligent Control Technology (CEI), Fuzhou, China, 2021. p. 480-484.
The photovoltaic storage system is introduced into the ultra-dense heterogeneous network of 5G base stations composed of macro and micro base stations to form the micro network structure of 5G base stations .
In Case 2, the total optimal energy storage planning capacity of large-scale 5G BSs in commercial, residential, and working areas is 9039.20 kWh, and the corresponding total rated power is 1807.84 kW. The total energy storage planning capacity of large-scale 5G BSs in Case 3 is 7742 kWh, which is 14.35% lower than that of Case 2.
The reason is that 5G BSs are configured with battery energy storage systems to store low-cost electricity. Moreover, the PV energy curtailment is significantly reduced in Case 2, and the PV absorption rate is effectively increased by planning battery energy storage systems.
