Going live with commercial EV charging is a fixed sequence, not a single event. You cannot energize before the meter is set and the inspector signs off, and you cannot commission network functions before the service is live. This article walks the go-live order step by step, explains what 'placed in service' means for incentives, and covers acceptance testing, the as-built package, and the operations-and-maintenance handover that determines how the site runs for years.

A commercial EV charging install is a sequenced construction job, not a product drop. The order is fixed: protect the site, do the underground and civil work, set the equipment, rough-in and pull wire, terminate, backfill and restore the surface, set the meter, and energize. Three inspection hold points gate that order, and you cannot bury an open trench or energize before sign-off. Most schedule pain comes from site conditions discovered in the ground, so the work that pays off is the work you do before the trencher arrives.

On a commercial EV charging project, the gear with the longest lead time sets the schedule, and in 2026 that gear is a transformer or a switchboard, not the chargers. This is a plain-language guide to the procurement mechanics: what counts as long-lead and why the 2026 shortage made it worse, when to release items to fabrication relative to permits and utility design, who should furnish the equipment, and the deposit, cancellation, and substitution terms that decide who carries the risk.

The service equipment, the switchgear, the metering, and the voltage you take service at are quiet decisions made in a one-line diagram most owners never read closely, and they are among the most expensive to get wrong. The biggest traps are utility-specific: every utility caps how large a single service can be (SDG&E's standard equipment tops out around 4000 amps), forces a switch from self-contained to CT metering above a certain size, and sets the point where you must own your own transformer and take primary service. This is a plain-language guide to those choices, the code clearances behind them, and how to pick equipment and a manufacturer without drowning in engineering detail.

Before a commercial EV project can draw power, the utility has to agree to serve the new load, and that process is a formal application: a load letter, a will-serve or service-planning letter, utility design of any transformer and feeder work, a line-extension or service agreement, then construction and energization. This article walks the workflow plainly, explains who pays for what through line-extension allowances and contributions in aid of construction, and makes the central point most owners miss: the utility owns the steps that set the schedule, so its design and construction lead times are the project's critical path.

The electrical infrastructure assessment is the most important step before committing budget to a commercial EV charging project. It determines whether your existing service can carry the load, what upgrades a NEC load calculation requires, and how much the project actually costs. Service and transformer limits discovered during construction, rather than before contracts are signed, are the leading cause of blown budgets and abandoned projects.

Most commercial EV charger projects run 4 to 9 months from first contractor meeting to operational chargers. Projects needing a utility service or transformer upgrade can run 12 to 24 months or more, because utility interconnection and the 2026 transformer shortage dominate the schedule. The federal 30C credit ended June 30, 2026, so project timing now rests on the build's own economics rather than a tax deadline.

Commercial EV charger installation is a construction project: electrical infrastructure, civil work, hardware mounting, network commissioning, permits, and inspection. The electrical scope is usually the largest and most variable cost. Most Level 2 projects run several months from first contractor meeting to operational chargers; anything requiring a utility service or transformer upgrade can run much longer. The federal 30C credit ended June 30, 2026, so timing now rests on the project's own economics rather than a tax deadline.
