TimberRock Energy Solutions & Standard Solar Partner To Install Solar EV Charging Station At
General Motors’ Allison Transmission Plant in White Marsh, Maryland
Frederick, Maryland, USA – October 12, 2011 – TimberRock Energy Solutions, Inc. has
commissioned Maryland’s first solar EV charging station at General Motor’s Allison Transmission
plant in White Marsh, Maryland. When asked by General Motors to design, build and provide a
leasing program for a solar EV charging station, TimberRock immediately turned to its long-time
partner Standard Solar, Inc., a leader in the full-service
development, construction, integration, financing and
installation of solar electric systems, to support the
execution of the project.
Standard Solar and TimberRock worked with General
Motors to design a 10kW system with four level 1 (120V)
charging stations and four level 2 (240V) fast charge
stations. The system offers covered parking for EV
drivers underneath an attractive solar canopy.
General Motors is at the forefront of electric vehicle development and is making significant
investments in the White Marsh facility. “We have recently completed a roof-mount solar system
and have also broken ground on an expansion program so as to produce EV motors in Maryland,
said Rob Threlkeld, GM Real Estate and Facilities Manager – Green Initiatives. “TimberRock’s solar
EV charging solution was a natural complement to these other investments and we’ve already begun
work on other projects with TimberRock.”
The system’s anticipated energy production is 12,500
kW-hrs per year; enough energy to fully power a fleet
of six Chevy Volts. The environmental benefits of
doing so are significant with twelve fewer tons of CO2
gas per year released into the atmosphere. In addition
to charging EVs, the system also ties directly to the
building so that when the charging stations are not in
use, the energy can be utilized throughout the building.
According to TimberRock CEO Brent Hollenbeck, “The introduction of production EVs has exciting
and positive implications for our dependence on foreign or polluting sources of energy. However, if
the vehicles are charged via grid-provided electricity – often from coal-fired power plants – the
benefits are mitigated. Solar-based EV charging makes sure that only renewable, local electricity is
used to charge clean vehicles.”
