Georgia pioneers energy-saving solutions
for transportation
BY LAURA SCHEPIS

PACE: What new technologies have been put in place
along The Ray?
Kelly: Owners of electric vehicles (EVs) have been reluctant to travel I-85 between Atlanta and Montgomery, Ala.,
because there were not enough charging stations. The
Ray's first technology demonstration was a fast-charging
station anchored to a small solar array that provides EV
drivers with an 80 percent charge to their cars in less than
30 minutes. This station addressed a critical gap in charging infrastructure along this important route.
Working with the Georgia Department of Transportation (GDOT), we've installed a 50-square-meter pilot of
Wattway, a solar pavement. It's the country's only drivable
solar road, highlighting how roadways can be used to generate electricity.
The Ray wants unpaved areas along the roadway-
including medians and shoulders-to multitask as energy
generators. This year, we'll install a 1-megawatt solar farm
in and along the interstate shoulder. The ground around
the solar farm will be covered with pollinator-friendly
flowers and grasses.
PACE: What aspect of The Ray's work has drawn the
most attention from consumers? From policymakers?
Kelly: Sustainability and safety go hand in hand. More than
40,000 roadway deaths occur annually in the United States
alone. Our safety-focused innovations have drawn a lot of
attention from transportation officials across the country.
The Ray has the world's first WheelRight tire safety
station, which is a convenient, drive-through station that

any thought leaders are attempting to envision how,
when and at what cost energy, telecommunications
and transportation will converge. Georgia is at the
forefront, with policymakers, utilities, consumers and
nongovernmental organizations hard at work.
A unique foundation is driving the conversation in
Georgia. The Ray, an independent nonprofit program of
the Ray C. Anderson Foundation, is using a dedicated
stretch of Interstate 85 in West Georgia to pilot new transportation and energy-saving technologies.
Allie Kelly, The Ray's executive director, talked with
the Northern Virginia-based Partnership for Affordable
Clean Energy (PACE) about how The Ray is demonstrating how smart transportation can help save and create
energy, save lives and protect the environment.

The Wattway pilot project features a roadway with embedded
solar cells. Wattway can be applied directly over existing paving,
which gives it the potential to be an energy-generating retrofit for
highways like The Ray. It could also be connected to feed electricity into the grid; power public lighting, road signs and signals; and
provide electricity to electric vehicle charging stations.

wall damage. The driver never leaves the vehicle, and
the analysis is available in just seven seconds. Drivers
can then make plans for needed maintenance or repairs.
The Ray is working with GDOT to develop selfdriving, or autonomous, vehicle technology and new
emergency-response methods for public roads to save
money and lives. In addition, we are testing sensors that
can be placed on roads to provide high-tech vehicles
with information about traffic and road conditions.

PACE: Describe some of the consumer benefits or cost
savings that are a result of The Ray projects.
Kelly: A key to serving consumers is establishing a robust, long-term EV-charging infrastructure. Our challenge
is to develop a charging infrastructure outside of major
metropolitan areas, and our charging station addresses
this need.
WheelRight also can benefit consumers with gaspowered vehicles. Every year, U.S. consumers waste
2 billion gallons of fuel because of worn-down, underinflated tires. That means that you end up going to the
pump more often and paying more to get where you're
going.
Laura Schepis grew up on Douglasville-based
GreyStone Power lines. She's worked on infrastructure
issues in Washington, D.C., for two decades. She now
serves as the executive director of the Partnership for
Affordable Clean Energy.
