In many emerging countries, grid supply by power companies is either insufficient or unavailable, and diesel generators are being used as the primary power source. Power generation using diesel generators presents two major issues, namely high fuel cost and CO₂ emissions. Based on the above, power supply using renewable energy such as solar power is expected to become the next alternative to diesel.
Telecom Energy Management System (hereafter, TEMS) for mobile telecom towers
In emerging countries, where mobile networks are the pivotal infrastructure for communications in off-grid regions not served by a grid and poor-grid regions suffering frequent blackouts, telecom towers providing mobile telecom services by obtaining their power supply from diesel generators.
In India, CO₂ emissions from telecom towers and subsidies for diesel fuel have become serious problems. Hence, reducing diesel generation for telecom towers through the introduction of alternatives such as solar power generation is urgently needed.
NEC is about to deploy TEMS using lithium ion batteries in India and expects to deploy TEMS to other countries as well.
NEC has been providing “Energy Management Systems" (hereafter, EMS) enabling efficient management of mixed power such as grid and solar, including but not limited to lithium ion batteries offering high-speed charging and longer battery life, and prediction of solar power generation and energy consumption by NEC’s state-of-the-art data analytics.
An EMS system consists of EMS servers located in data centers and a remote EMS controller at each site.
