Why Businesses Are Installing Commercial EV Chargers

Commercial charging stations have become practical business assets, not just sustainability gestures.

• Customer and tenant retention. Shoppers, hotel guests, and office tenants increasingly expect charging as a standard amenity. Properties that offer it see longer dwell times.
• Employee recruitment. Workplace charging signals a forward-thinking culture and helps attract and retain talent.
• New revenue. Pay-per-use models let property owners generate income. Even modest per-session fees add up across a busy lot.
• Property value. Buildings with charging infrastructure appraise higher and lease faster, particularly where green building certifications such as LEED carry weight.
• Sustainability goals. For companies with ESG commitments or carbon reduction targets, chargers provide measurable progress.

Best Locations for Commercial EV Chargers

Not every parking space is a good fit. The most successful installations match charger placement to how drivers actually use the property.

• Retail centers. Shoppers park one to three hours, which is ideal for Level 2. Chargers near entrances see the most use.
• Office buildings and campuses. Employees park eight or more hours, so even slower Level 2 units are highly effective.
• Hotels. Overnight guests can charge fully during their stay. The Aloft Tempe Hotel is one example of a property investing in charging.
• Multifamily housing. Chargers attract and retain tenants, and many jurisdictions now require EV-ready parking in new developments.
• Fleet and logistics hubs. Delivery companies, service fleets, and municipal yards need reliable overnight charging, which requires careful planning around power capacity and scheduling.
• Healthcare facilities and universities. Large workforces and high visitor volume make these strong candidates.

Commercial EV Charger Types

Choosing the right charger level is one of the most consequential decisions in the project, and the cost difference between levels is substantial. Our guide to the types of EV chargers goes deeper.

Level 1 (120V)

Level 1 plugs into a standard 120 volt outlet and adds roughly 3 to 5 miles of range per hour. Installation is minimal but it is too slow for most commercial applications. It can supplement workplace settings where vehicles sit for full shifts, but it is rarely the right primary solution.

Level 2 (208 to 240V)

Level 2 is the standard for most commercial installations, adding 12 to 80 miles of range per hour depending on the charger’s output and the vehicle’s onboard charger. It suits retail lots, offices, hotels, multifamily properties, and anywhere vehicles park from 30 minutes to several hours.

These come in wall-mounted and pedestal configurations and use the J1772 connector, compatible with all EVs sold in North America. Tesla vehicles use an adapter, or the NACS connector that many Level 2 stations now support.

Level 3 / DC fast chargers

DC fast chargers add up to 150 miles or more of range per hour, with some newer models delivering 10 miles of range per minute. They run at 480 volts or higher and use CCS or NACS connectors. They suit highway corridors, gas stations and convenience stores, high-turnover retail, and fleet depots that need rapid turnaround. Hardware and infrastructure costs are substantially higher than Level 2.

How Much Does Commercial EV Charger Installation Cost?

Level 2

• Hardware: $500 to $2,500 per port for commercial-grade units
• Installation and labor: $400 to $1,800 for basic wiring, conduit, and panel access
• Electrical infrastructure upgrades: $2,000 to $50,000 or more for transformer upgrades, panel capacity, and conduit runs
• Permitting and inspection: $500 to $5,000 or more depending on jurisdiction
• Networking and software: $200 to $1,000 per charger per year
• Total installed cost per charger: $3,000 to $15,000

Most Level 2 commercial installations land in the $6,000 to $15,000 range per charger once equipment and installation are combined.

DC fast charging

• Hardware: $25,000 to $140,000 or more for high-power models
• Installation and infrastructure: $20,000 to $60,000 or more per port
• Total installed cost per charger: $80,000 to $250,000 or more

What drives the number

Existing electrical capacity is the biggest variable. If your panel can handle the added load, costs stay low. If you need a panel upgrade, a new transformer, or upgraded utility service, expect significant added expense.

Distance from panel to charger drives material and labor cost, and trenching through landscaping or parking lots adds more.

Number of chargers raises infrastructure investment but lowers per-unit cost through economies of scale.

Local permitting varies. Some municipalities require separate electrical permits, building permits, and utility interconnection approvals. In Tucson your installer should coordinate with the local building department and Tucson Electric Power for service upgrades.

ADA compliance. At least one station must meet accessibility standards, which affects parking layout and equipment placement.

Incentives for Commercial EV Charging

Incentives can meaningfully reduce net project cost, but the federal landscape has shifted, so verify current status before building a business case around any single program.

Alternative Fuel Vehicle Refueling Property Credit (Section 30C)

This federal credit was the most significant incentive for commercial charging, worth 6% of project costs per port up to $100,000, or 30% where prevailing wage and registered apprenticeship requirements were met. The credit terminated for property placed in service after June 30, 2026, so it is no longer available for new projects. If your project was placed in service before that date, talk to your tax advisor about claiming it.

National Electric Vehicle Infrastructure (NEVI) Formula Program

NEVI provides federal funding to states for public charging infrastructure, covering up to 80% of project costs for qualifying installations. It is directed primarily at DC fast charging along designated Alternative Fuel Corridors. Funding timelines and eligibility have been in flux, so check the current program status with the Arizona Department of Transportation before counting on it.

State and utility programs

Many utilities offer rebates and grants for commercial customers. In Arizona, check with Tucson Electric Power and the Arizona Corporation Commission for programs that currently apply in the Tucson metro.

The Installation Process, Step by Step

A well-planned project follows a structured process, and it is worth confirming that current installation requirements are met at each stage.

Step 1: Site assessment and electrical evaluation. A qualified commercial electrician evaluates panel capacity and available amperage, transformer size and utility service rating, distance from panel to proposed charger locations, parking layout and ADA requirements, existing conduit pathways, and soil conditions if trenching is needed.

Step 2: Charger selection and system design. You choose the charger type, port count, and whether to go networked or non-networked. Networked chargers connect to a cloud platform for payment processing, usage monitoring, remote diagnostics, and access control, and many run on OCPP, an open standard that avoids vendor lock-in. Non-networked units are simpler and cheaper but lack remote management, which suits private fleet or employee-only installations.

Step 3: Permits and utility coordination. Before construction, your installer files permit applications and coordinates with the utility. In Tucson that typically means an electrical permit, a building permit if structural changes are needed, a utility interconnection application where service upgrades are required, and an ADA compliance review. Simple Level 2 installations may clear permits in one to two weeks; larger projects involving utility upgrades can take one to three months.

Step 4: Electrical infrastructure upgrades. This covers panel upgrades or new subpanels, transformer work, trenching and conduit runs, and dedicated circuits for each station. Where trenching must cross parking lots or landscaping, directional boring minimizes surface disruption. This is usually the most expensive and time-consuming phase.

Step 5: Installation and wiring. Chargers are mounted and secured, wiring is connected from the dedicated circuits, cable management and protective conduit go in, and signage and parking striping are completed.

Step 6: Testing, inspection, and activation. Each charger is verified for correct voltage and amperage, ground fault protection and safety shutoff, network connectivity, and payment processing. A final building department inspection confirms code compliance before activation.

Step 7: Ongoing maintenance. Regular inspection of cables, connectors, and housings; software and firmware updates; monitoring usage data and error codes; clearing debris; and replacing damaged cables promptly. Load management systems help prevent the demand spikes that drive up electricity costs by distributing available power across chargers based on real-time demand.

Networked vs. Non-Networked

Networked chargers provide remote monitoring and diagnostics, payment processing by card, app, or RFID, usage analytics, over-the-air updates, access control, and integration with load management.

Non-networked chargers offer lower upfront cost, simpler installation, and no monthly software fees, which works well for private or restricted-access locations.

For most commercial stations open to the public, networked is the better choice. The data and revenue capabilities justify the cost.
