Commercial Level 3 EV Charging Stations
Overview
Oahu Electric and Air provides full electrical services for commercial Level 3 EV charging stations across Oahu. We install clean, reliable fast-charging infrastructure that meets utility requirements, site demands and modern EV fleet needs. From site prep to final energization, our team builds systems ready for high-load continuous operation.
​
What We Do
We manage the entire electrical scope for commercial charging installations, including power upgrades, service gear, conduit work, equipment circuits, utility coordination and commissioning. Our team works closely with site owners, engineers, utility planners and manufacturers to ensure every charger operates safely and efficiently.
​
Our Capabilities
Our team is built for large-scale EV charging infrastructure. We handle complex load requirements, high-amp circuits, long conduit runs, civil coordination and tight commercial schedules. With experience installing Level 3 fast chargers and working directly with Tesla, ChargePoint and other major manufacturers, we deliver organized, code-compliant installations from rough-in to operational hand-off. Our capabilities include utility coordination, large gear handling, trenching support, commissioning assistance and high-demand commercial power distribution.

​​How We Work With Your Team
We coordinate closely with your GC, engineers, utility planners and charger manufacturers to keep your project running smoothly. Our team communicates clearly, stays organized and adapts to changing site conditions, utility requirements and equipment specifications.
Why It Matters
Level 3 charging requires precise electrical planning to avoid delays, rework or safety issues. Proper conduit routing, correct feeder sizing and clean terminations ensure chargers deliver full output and operate reliably under continuous high load. Strong planning saves time and keeps the project on schedule for energization.
