Occurring in industrialized nations, inexpensive and abundantly available power is routinely taken for granted. However, energy resilience and to a lesser extent price are key concerns when considering potential solutions for disaster response, disaster relief, or military operations. The Department of Defense (DoD) currently uses a 5 kW generator to power the E700XD portable Doppler radar system when grid power is unavailable [1]. While the radar has an approximate power consumption of 2.5 kW, there is a potential for higher demand due to weather conditions [2]. This paper examines the cost of operating a currently installed generator, compared to the cost for an optimized hybrid generator and battery system. The optimized energy system design includes a 2.75 kW generator, 3 kWh battery and inverter/charger. This design reduces the annual cost by nearly 50% when considering the component cost and the cost of fuel. In addition, the battery allows for an hour of operation in the event of a disruption to the primary generator solution, increasing the resiliency of the system.
