NTT Docomo's Green Base Stations

GSMA Future Networks detail a case study on NTT Docomo's Green Base Station:

NTT DOCOMO have developed Green Base Stations, a non-traditional, environmental-friendly and sustainable energy supply scheme for radio base stations.

Green Base Stations are equipped with photovoltaic (PV) panels, cycle-type Li-ion storage batteries, DC power controllers, and supply generated power to radio equipment with smart power control. They can make use of renewable energy by local PV power generation, therefore can reduce CO2 emission from commercial electric power use. Additionally, in case of a power outage due to disaster, they work longer time by PV power generation rather than relying on backup power alone.

Green Base Stations have been installed since 2013 and a total of 133 stations were installed by March 2018. The company aims to increase PV generation capacity to 2000 kW by 2020. Mobile network operators (MNOs), introducing 5G networks, will increase consumption of electric power for 5G network facilities in the future, and are expected to reduce power consumption both in terms of business and CSR requirements.
