Mobile Electric Power Project: U.S. Army

NREL is working with the U.S. Army to simulate and design a mobile hybrid power system that incorporates solar and battery energy to reduce fuel consumption by diesel generators.

Through extensive analysis, sizing, and design, NREL and the U.S. Army have created a prototype that implements the hybrid power system electronics and controls in a lightweight, mobile unit. This mobile unit allows for rapid deployment and connection of photovoltaic arrays and battery energy storage along with the standard military diesel generators used today. The unit leverages these energy resources, advanced liquid-cooled power electronics, and intelligent dispatch and fuel-saving algorithms to provide reliable and secure electricity for military bases constrained by fuel availability.

The prototype is being developed and tested at NREL's Distributed Energy Resources Test Facility to optimize operation and performance.
