In a previous study, Raytheon found that short duration Li-ion energy storage can be used in Department of Defense (DOD) microgrid installations to improve reliability and significantly reduce costs compared to all-diesel microgrids.

The project profiled in this case study builds on the previous one and demonstrates that a PXiSE Microgrid Controller, when coupled with a battery energy storage system (BESS), can enable the microgrid’s batteries to achieve uninterrupted power source (UPS) functionality while also reliably performing islanding transitions and steady-state operation.
