Backup power is one of those cabinet decisions that shows up later. It shows up during an outage when an intersection drops into flash. It shows up during heat waves and cold snaps when energy storage performance becomes less predictable. It also shows up in day-to-day operations, when replacement cycles and field maintenance needs begin to compete with higher-priority work such as detection upkeep, timing reviews, and construction support.
On April 23, 2026, at 2:00 PM Eastern, Western Systems is hosting a technical webinar focused on SuperMax™, our ZX2000-48 Graphene Supercapacitor Power Module designed for long-life energy storage in critical infrastructure environments.
Why Backup Power Conversations are Changing
Many agencies are being asked to do more with the same staff time. When energy storage requires regular testing, replacements, and disposal planning, it creates a steady cadence of cabinet visits that can be hard to sustain at scale. At the same time, more intersections are adding communications equipment, detection, and other field devices that increase the operational importance of stable power.
This webinar starts with industry context and a brief overview of how backup power strategies are evolving as agencies focus on resilience, maintainability, and predictable lifecycle planning.
What Makes Supercapacitors Different in Cabinet Environments
SuperMax™ is built around supercapacitor technology, which is often evaluated for applications that see frequent charge and discharge cycles. For agency teams, the practical question is not just “Will it run?” The question is “How does it behave across seasons, across site types, and across years of field conditions?”
What The Technical Deep Dive Will Cover
The session is designed to be hands-on and deployment-oriented. Topics will include:
- How supercapacitor technology fits into modern traffic signal backup power systems
- Configuration requirements and integration considerations for cabinet environments
- Runtime expectations based on load and how to plan for real-world use cases
- Application fit, including intersections with frequent cycling, solar-supported deployments, and locations with harsh temperatures
Fit Considerations Sgencies Can Bring to The Webinar
Attendees will get the most value by coming with a few site realities in mind:
- Which locations see the most heat exposure or the coldest starts
- Which corridors experience frequent cycling due to utility conditions or solar operation
- What loads need support, including cabinet and ITS device needs
- How many field replacements per year are currently built into the maintenance plan
These details help move the conversation from technology concepts to practical decisions.
What This Can Mean for Crews and Resilience Planning
A recurring theme in cabinet work is predictability. When agencies can reduce the frequency of energy storage replacements and better understand cabinet power status, teams often gain time back for core system performance work.
