Is there a special utility rate for commercial EV charging?

Whether any of these exists for you is a fact about your utility, not about the industry. We name no program and quote no amount here, because a program figure is only worth publishing attached to a named sponsor and the date somebody read it on the sponsor's own page. What travels nationally is the arithmetic, which is the rest of this article.

Write it out and the break-even falls out as a ratio: the demand rate divided by the difference between the two energy rates gives you kilowatt-hours per kilowatt of peak. Divide that by the roughly 730 hours in a month and you have a break-even load factor.With the illustrative rates below — nine cents a kilowatt-hour plus eighteen dollars a kilowatt on the standard schedule, sixteen cents and no demand charge on the EV schedule — the break-even is 18 divided by 0.07, or about 257 kilowatt-hours per kilowatt of peak. That is a load factor of roughly 35 percent. Below it the EV schedule wins; above it the standard schedule does.

A depot early in an electrification program has a low load factor almost by construction: the infrastructure is sized for the fleet you are going to have and serving the fleet you do have. That is exactly the profile a demand-light schedule flatters.Then vehicles arrive. Energy climbs, the peak stays roughly where the cap holds it, and the load factor rises — which is the mechanism by which a schedule chosen in year one becomes the wrong schedule in year three. Model it at today's fleet, at the fleet in the plan, and at full build, then decide.

Many tariffs impose a minimum term on an elective schedule, commonly a year, and limit how often an account may change. That is reasonable regulation and it is also a trap for a load that is growing quickly, because the schedule you elect in the month you commission twenty ports is the schedule you keep while those ports fill up.A demand-charge holiday deserves the same scepticism. It is deferred cost, not removed cost, and the phase-in is published. Build the bill for the year the relief ends. If the operating model only works during the holiday, the model is the problem, not the tariff.

The fifth step is worth doing even when you have done the work yourself, because the utility's analysis will surface schedules you did not know you qualified for. The check on it is the load assumption: an analysis run on last year's consumption tells you which schedule would have been right for a depot you no longer operate.

Section 30C terminated for property placed in service after June 30, 2026 and nothing federal replaced it. A capital proposal that shows a federal credit reducing your charging infrastructure cost is quoting a rule that has expired, and it should be corrected before it goes to whoever approves the spend.What is left is the state layer and the utility layer, and on the utility layer the rate schedule and the incentive program can interact in both directions. Some managed-charging and make-ready programs require enrolment on a particular schedule; occasionally an elective schedule disqualifies you from a program. Ask both desks the same question before electing anything, because they do not always ask each other.
