As mobile communication networks continue to expand, energy storage systems for telecom base stations have become a critical foundation for network reliability and operational resilience. Beyond emergency backup, modern storage systems now deliver measurable economic, environmental, and grid-level. These batteries store energy, support load balancing, and enhance the resilience of communication infrastructure. The base station microgrid energy management system (BSMGEMS) is crucial to unleash these potentials. This paper presents a brief review of BSMGEMS. By combining solar, wind, battery storage, and diesel backup, the system ensures 24/7 uninterrupted operation.
