Clear answer, explained.
The physical installation is often the fastest part of a commercial EV charging project. The longer timeline comes from the steps that must happen before installation begins: electrical design, equipment procurement, ESA permitting, ZEIP pre-approval where applicable, and utility coordination for large load additions.
ESA permit approval in Ontario typically adds two to four weeks to the timeline. ZEIP applications add additional time that varies by program stream and current processing volume — confirming ZEIP application status before committing to an installation date is essential to avoid missing the incentive window. For projects combining EV charging with rooftop solar or battery storage, the interconnection process for the generation system runs on a parallel timeline and should be coordinated together.
Early planning is the most effective way to avoid timeline pressure. Facilities with defined installation targets — new lease commencement dates, ZEIP program deadlines, or fleet vehicle delivery schedules — should begin the design and pre-approval process at least three to four months before the target date.
What this means in practice.
- Physical installation: 1–3 days for standard projects
- Full project timeline: 6–12 weeks including approvals
- ESA permitting adds 2–4 weeks to the timeline
- ZEIP pre-approval must be confirmed before installation
- Equipment procurement lead times can extend the schedule
- Solar/storage integration should be scoped in parallel
Best-fit environments.
