Commercial EV Charger Installation: Costs, Incentives and Timeline

Every project starts with an electrical and physical assessment. We review the existing service capacity, panel space, transformer size, conduit routing distance and parking layout. The distance between the electrical room and the parking stalls is usually the single largest cost driver, because trenching and boring often cost more than the chargers themselves.

The assessment also determines whether Level 2 charging is enough or whether DC fast charging is justified by dwell time. Multifamily and workplace sites usually suit Level 2. Retail, hospitality and fleet depots typically justify DC fast charging.

If existing service cannot support the planned load, options include load management software, a service upgrade, or pairing chargers with battery storage to shave demand peaks. Utility coordination and any required service upgrade is often the longest lead item on the schedule, so it is started early.

The federal Alternative Fuel Vehicle Refueling Property Credit can cover 30% of qualified commercial charging equipment and installation costs, subject to per unit caps and to prevailing wage and apprenticeship requirements. Eligibility depends on the census tract the property sits in, so it is confirmed during the assessment.

Utility rebates, state programs and make ready funding frequently stack on top of the federal credit. Consult your tax advisor for how the credit applies to your entity.

Permitting requirements vary by jurisdiction and typically include electrical permits, accessibility compliance for parking stalls and inspection sign off. Installation is performed by licensed electricians, including panel work, conduit, trenching, bollards, signage, commissioning and network activation.

A straightforward Level 2 project with adequate existing capacity often runs four to eight weeks from assessment to energization. Projects requiring a utility service upgrade or DC fast charging commonly run three to six months, driven largely by utility and equipment lead times.

Chargers are revenue and amenity infrastructure, so uptime matters. Ongoing service covers remote monitoring, firmware updates, payment and pricing configuration, warranty administration and on site repair. OneSource supplies the chargers, installs them and maintains them afterward under one contract.
