Fort Buchanan Directorate of Public Works
As part of Installation efforts to increase energy efficiency, improve infrastructure and reduce its resource “bootprint,” Fort Buchanan in Puerto Rico has plugged into electric vehicle charging stations.
Fort Buchanan’s mission is to provide standardized services and sustainable infrastructure in support of the Armed Forces and the diverse Fort Buchanan community. The Garrison is committed to protecting natural, cultural and human resources; promoting pollution prevention through the continual improvement of environmental management technologies; and implementing energy, water and fuel efficiency measures that comply with all applicable laws, regulations and Executive Orders. To that end, the Fort Buchanan Directorate of Public Works has leveraged funding through an Energy Savings Performance Contract to install eight electric vehicle charging stations on post.
The electric vehicle charging stations will provide power to the new plug-in hybrid electric vehicles in the Installation’s General Services Administration fleet, and they are located at the Directorate of Public Works, at the 1st Mission Support Command and at the Logistics Readiness Center.
Fleet managers can use remote management and control services to monitor the use status of each station, determine the amount of power flowing to each vehicle and identify any required preventative maintenance.
In conjunction with this effort, Fort Buchanan’s Logistics Readiness Center has collaborated with the General Services Administration fleet manager to acquire more electric vehicles through a continuous vehicle replacement program, which will replace every fossil fuel vehicle in the fleet with a hybrid electric or plug-in hybrid electric vehicle. This replacement program will support the Installation’s “Environmental Management Action Plan #1: Fleet Fuel Efficiency Management,” which aims to reduce fleet greenhouse gas emissions by 30 percent by fiscal year 2025; to create a fleet comprised primarily of plug-in hybrid electric vehicles; to provide appropriate charging or refueling infrastructure for zero emission vehicles or plug-in hybrid electric vehicles; and to implement fleet efficiency management tools.
During the last week of fiscal year 2016, the Logistics Readiness Center received three plug-in hybrid electric vehicles, and they expect to receive two hybrid electric vehicles and nine plug-in hybrid electric vehicles in fiscal year 2017.
This plug-in hybrid electric vehicle technology combines a high capacity battery with an electric motor with a gasoline engine.
When it is connected to a standard 120-volt or a 240-volt electrical outlet or charging station, the vehicle’s battery can store enough electricity from a power grid or a solar photovoltaic canopy for the vehicle to operate in electric mode under typical driving conditions and during a short commute, therefore significantly reducing the vehicle’s petroleum consumption.
When the battery is depleted, the vehicle then functions in hybrid mode with a regenerative braking system. An “Electric Vehicle,” or “EV,” button allows the vehicle to operate in one of three modes. In “EV Now” mode, the vehicle will operate using primarily battery power. In “Automatic EV” mode, the vehicle will use battery power when possible and move to gas engine power when needed. In “EV Later” mode, the vehicle will save battery power for future use.
Fort Buchanan will continually strive for energy efficiency not only by conserving electric energy but by reducing fuel consumption as well. The plug-in hybrid electric vehicles use about 30 to 60 percent less petroleum than the conventional vehicles.
