KDDI has launched the 'Tribrid Project' to reduce carbon by base stations in Indonesia.
According to KDDI, Tribrid Systems make efficient use of power by alternating commercial-use power, solar power and late-night battery charging, depending on time of day and weather conditions. In this demonstration project, Tribrid System is installed to 20 conventional BTSs in Indonesia to demonstrate that the overall greenhouse gas emission of BTSs can be reduced by up to 80%, claims KDDI.
In January 2015, KDDI began introducing Tribrid BTSs in Indonesia after it first introduced the system in Japan in December 2009. Since then, the number of Tribrid BTSs has expanded to 100 nationwide. By converting 5% to 10% of the base stations in Indonesia that lack commercial-use power sources or are otherwise susceptible to power supply instability, they aim to improve energy conservation by the equivalent of approximately 70,000 tons of greenhouse gas emissions per year.
