Power & Mobility: Defining the Financial and Operational Value of Vehicle-to-Grid Technologies for the United States Department of Defense

March 5, 2012 - 10:30am
Seminar Host/Point of Contact: 

In November 2010, the Department of Defense (DOD) initiated a comprehensive analysis to identify the key opportunities and barriers for executing a large-scale integration of plug-in electric vehicles (PEV’s) into its non-tactical ground fleet. This analysis led to a series of targeted investigations that are intended to develop an overarching DOD PEV strategy. Central to development of this strategy is the acknowledgment and acceptance of current fiscal constraints. The size of DOD’s non-tactical ground fleet is shrinking, as is its overall budget. Thus, it is highly unlikely that DOD will be able to execute a large-scale integration of PEV’s unless a strategy is undertaken to achieve total cost of ownership parity with conventional vehicles. Among the core tactics being considered to improve the overall PEV financial outlook is the use of vehicle-to-grid (V2G) technologies. By utilizing the PEV fleet as an energy resource to DOD installations and to the public electrical grid, it is believed that substantial revenues and cost savings will be realized. While the specific financial proposition for V2G varies significantly between facilities, it is also likely that V2G technologies can be used to provide energy surety to DOD installations both domestically and abroad. Whether incorporated into a microgrid or simply providing back-up power to a small facility, PEV’s with V2G capability can serve as an essential energy resource beyond their primary mobility function. Considering the financial and operation value of V2G, DOD is actively exploring strategies to expand the range of potential benefits and functions provided by the standard fleet vehicle.  A recording of this seminar is available at http://www.vimeo/37989037
