Protecting motorists at Biggs Junction was a big priority for us and the UPStealth is performing just as promised, keeping the power on and reducing accidents and congestion. There’s less maintenance, decreased cost and longer battery life.”

“ZincFive’s nickel-zinc batteries proved they don’t generate heat, toxic chemicals and fumes. They’re compact and can be installed on the existing data center rack. We save space by rack mounting and no longer have to worry about lead-acid leaks from batteries.”


 Ernie Pierce. Traffic Engineer. City of Knoxville

“I think the real savings is not only in labor materials and equipment savings but in road user cost--reduced delay, fewer crashes, and peace of mind during power outages on the roadways.”

Adam Lough. Signal Engineer. Utah DOT

"We absolutely love it. It has been rock solid and easy to use. It was so easy to install and fits great without taking up too much room. It is going to be a great solution for us.


Case Studies

Atlanta, Georgia

UPStealth’s ability to fit inside existing cabinets and provide sine wave monitoring and power conditioning proves to be the reliable solution for GDOT.

“When you start having the conversation about autonomous and connected vehicles, reliance on an infrastructure that stays powered 100 percent of the time has absolutely never been more critical.” 

Jason Lewis, GDOT project manager with Brooks-Berry-Haynie & Associates.

Cedar Park, Texas

UPStealth is an important part of keeping the City of Cedar Park traffic moving when power failures occur at their Continuous Flow Intersection and critical traffic infrastructure.

“UPS will play a greater role as our transportation network continues to grow and usage increases.  It will become more and more critical for traffic signals, particularly those at major, complex, and closely spaced intersections, to be able to operate without interruption during power outages and brown outs.  Our goal would be for drivers not to even notice that there is a power outage.”

Stephen Hanuscin, P.E. City of Cedar Park. Senior Traffic Engineer

Oregon Department of Transportation

Oregon Department of Transportation installed three UPStealth® Battery Backup System units at three intersections built as apart of the I-84 @ U.S. 97 Interchange project.

“This looks like a win-win all the way around. The UPStealth is quick and easy, actually fitting inside the existing traffic signal controller cabinet. With less stuff on the streets there is less maintenance and less chance it will get hit. There could be less cost and a longer battery life, and that appeals to our retrofit projects.”

City of Loveland, Colorado

Loveland, Colorado finds a nickel-zinc solution to its challenges of increased congestion, wily weather extremes and safety concerns about lead-acid batteries.

“Our goal is to have all our signals and other ITS devices, such as variable message signs and remote weather information systems, backed up using the nickel-zinc, UPStealth.”

Utah Department of Transportation

UPStealth® is a critical component to the Utah Department of Transportation's goals for connected traffic signals that stay operating even when the power fails - increasing mobility, safety, and quality of life.

“Innovation, creativity, risk and increased transparency are necessary to meet a growing society’s transportation needs. A part of any traffic signal management plan should be consideration of where to deploy an Uninterruptible Power Supply, so mobility is optimized and conditions are safe.”

— Mark Taylor. Lead Signal Operations and Maintenance Engineer, Utah Department of Transportation

City of Sacramento, California

City of Sacramento installed the UPStealth® Battery Backup System as a solution to backing up critical rail and traffic intersections.

“The UPStealth saves us money. We don’t have to go out and condition the UPStealth as we did with the lead-acid batteries. We no longer have the huge costs for on-call, after hours and during work hours maintenance. It’s a huge amount of money for our staff to keep going out there. Now with the UPStealth, we’re saving thousands of dollars a year.”

— Norm Colby. City Operations General Supervisor City of Sacramento

City of Knoxville, Tennessee

With a "Living Green, Working Green" initiative, the City of Knoxville, Tennessee installed the UPStealth® Battery Backup System.

“During a big thunderstorm, I was driving in an area where we have a UPStealth Battery Backup System and the other signals around did not. The only signal working was the signal with the UPStealth. Not only a wow moment, but also a reminder of the reason for our city-wide program.”
