  • Assessing a Mobile Microgrid to Support Electric Vehicle Charging Stations on Army Installations

    Abstract: Supplying reliable, off-grid power is critical for transitioning the Army’s fleet to zero carbon emitting vehicles. At the same time, vehicle charging and mission support equipment may require increased electrical loads than currently experienced at Army installations. Other decarbonization initiatives require clean sources of energy. Using microgrids powered with renewable electricity generation systems is a viable, independent solution for powering electric vehicles. Yet, there is a need to fill information gaps in the performance of these systems for realizing sustainable and resilient energy. The goal of this project was to increase the Army’s energy resilience by reducing reliance on the utility grid by using a compact and mobile microgrid that functions as an EV charging station. In this study, a trailered, mobile microgrid that integrates solar panels, a diesel generator, and batteries is evaluated based on performance under varying conditions. The energy generation capabilities are documented and evaluated for capabilities for powering electric vehicles. The outcomes of this research are the advancement of energy resiliency and the addition of performance in temperate and cold regions to the knowledge base. It is also anticipated this research may be leveraged to facilitate power independence and further support decarbonization efforts.
  • Pittsburgh District provides power team to hurricanes Ian and Fiona relief effort

    Imagine everything in your house – furniture, family heirlooms – floating away in a flood. Then imagine your house floating away in it, too. To call it ‘bleak’ is an understatement. However, that is the terror many experienced in September when hurricanes Ian and Fiona devastated Puerto Rico and the southeastern corner of the United States.
