Japanese investment holding company Softbank Group is testing a new type of cellular base station that generates a significant portion of its electricity from solar and wind sources. The pilot system is installed at one of the company's facilities in Ichihara City, Chiba Prefecture.
This study evaluates the reliability and economic aspects of three hybrid system configurations aimed at providing an uninterrupted power supply to base transceiver stations (BTS).
A hybrid energy system integrates multiple energy sources-typically combining solar energy, wind power, and diesel generators or battery storage. The main loads of those small base station are 48V with rated 500W power more or less, the daily power consumption is about 12kwh.
Despite the lack of water storage, run-of-the-river hydropower plants are also attractive for hybrid systems owing to their low investment cost, short construction time, and small environmental impact.
Hybrid energy solutions enable telecom base stations to run primarily on renewable energy sources, like solar and wind, with the diesel generator as a last resort. This reduces emissions, aligns with sustainability goals, and even opens up opportunities for carbon credits or green.
When power outages strike or when you need reliable portable power, solar gas hybrid generators offer versatile and efficient solutions. These generators combine the convenience of gas or propane fuel with solar energy to ensure uninterrupted power supply.
The DHYBRID UPP is manufacturer and technology independent and allows the implementation of different energy sources into one economic and sustainable hybrid power supply.
