Strengthening Mission-Critical Microgrids with Battery Energy Storage Systems

This white paper discusses the integration of battery energy storage systems (BESS) within microgrids to enhance operational resilience and sustainability. It begins by outlining the challenges faced by U.S. electricity customers, who experienced significant power interruptions in 2021 due to various factors. The paper explains the concept of microgrids, which are self-sufficient energy systems capable of operating independently or in conjunction with the central grid. It details the characteristics of microgrids, including their ability to provide local power access and their potential for reducing emissions through the use of low-carbon energy sources. The document also highlights the role of microgrid control systems in ensuring power continuity and managing energy resources efficiently. Furthermore, it presents the advantages of BESS in comparison to traditional diesel generators, emphasizing their ability to provide always-on energy and contribute to cost savings and grid services. The paper concludes with considerations for planning BESS integrations into microgrids.
