Fuel delivery to forward operating bases (FOBs) in Afghanistan and Iraq is problematic. Fuel in transit requires personnel and equipment for storage, handling, transport, and protection. More importantly, attacks to fuel convoys accounted for more than 50% and 30% of casualties in Afghanistan and Iraq respectively during 2009. Therefore, reducing fuel consumption at FOBs will translate directly into reduced casualties. Photovoltaic (PV) energy technologies could reduce fuel consumed at FOBs for electricity generation, thus reducing supply chain burdens. Current approaches to microgrid optimization are solely concerned with fuel consumed at the FOB itself during operation (i.e. running diesel generators). This point-of-use energy analysis fails to consider the supply chain implications. By contrast, this study performs a systems energy analysis by modifying existing microgrid optimization tools and extending the …
