Interconnection is the schedule. Manage it like one.

Revio 360 · August 2026

Chargers are a procurement item. Concrete is a subcontract. The utility service is neither — it is a queue, governed by the utility's studies, the utility's equipment lead times and the utility's crews. On a high-power charging project, interconnection is almost always the critical path, and every week it is treated as paperwork instead of schedule is a week added to energization.

What the utility actually has to do

A serious DC fast site is a new industrial-scale load on a distribution circuit that was planned decades before anyone priced a kilowatt-hour by the session. Before it energizes you, the utility must evaluate the circuit's headroom, design the service, often procure a transformer — the single most schedule-defining piece of equipment in the industry right now — and schedule construction crews against every other project in the territory. Each step has intake windows, review cycles and dependencies the applicant does not control.

What the applicant does control is the quality and timing of what enters the queue: a complete application, a competent single-line diagram, load calculations that survive review, and answers that come back in days rather than weeks. Files that churn — incomplete data, revised loads, redesigned layouts mid-study — go to the back of lines that are already long.

Make-ready: the program that moves the trench

California's investor-owned utilities operate make-ready programs that can put utility-side — and in many cases customer-side — infrastructure costs on the utility's books for qualifying charging projects: the service extension, the transformer pad, the conduit and trench that would otherwise be the project's most stubborn line items. These programs have eligibility windows, design standards and their own queues, which is precisely why they must be engineered into the project at application time. A site designed without the program's standards in mind forfeits money that was sitting on the table.

Sequence everything against the service date

Run the project backward from energization. The utility application files the week site control firms up — not after permits, not after final design. Incentive applications move in parallel, because several programs must approve before construction starts. Permitting proceeds while the utility studies. Equipment is scheduled against the service date, not the pour date; power cabinets staged in a laydown yard help no one. On this sequencing, months of dead time simply never accrue.

One team, one accountability

The pattern behind late charging sites is fragmentation: an electrical engineer who has never filed this utility's application, an incentive consultant who arrives after design freeze, a GC who meets the single-line diagram at mobilization. The pattern behind on-time sites is one team advancing the utility file, the incentive stack, the permits and the construction package together — with one point of accountability for the only date that matters: the day the site sells its first kilowatt-hour.
