Are EV Chargers Worth It for a Property? Three Outcomes, Not One

A charging installation on a commercial property lands in one of three places, and the industry habit of arguing "yes, EV charging is worth it" without saying which one is why so many owners feel misled a year in.Amenity means the property carries a net cost and gets something other than money back: a leasing talking point, a retention argument, a corporate sustainability line. Cost recovery means session revenue covers the operating cost of the chargers — energy, demand, network fees, payment processing, maintenance — with capital treated separately as a building improvement. Profit means revenue covers operating cost and returns the capital on a schedule anyone would recognise as an investment.The separator between them is throughput: kilowatt-hours actually delivered per port per day. Everything else in the economics is downstream of that one number.

A port cannot deliver more energy than the time a car spends plugged into it allows. That is arithmetic, not an opinion, and it caps the revenue side before any pricing decision gets made.The table below is straight multiplication: charger power multiplied by hours connected. Real deliveries land below every one of these figures, because a car that arrives at sixty percent state of charge stops drawing long before it leaves, and because charge rate tapers as the battery fills. Treat the numbers as a ceiling you will never touch, not a forecast.Which row you are on is a fact about your property. Take it from your own parking data — gate logs, permit records, a leasing manager who knows when the lot empties — and not from an industry average.

Dwell sets the ceiling. Port scarcity decides how close you get to it. A property with two ports for three hundred apartments will saturate them; a property with twenty ports for the same three hundred apartments will watch most of them sit empty most nights, and the empty ones still pay a network subscription.Divide your parking stalls by your units, or by your leased headcount for an office. Below roughly one stall per unit, parking is contested, drivers will not tolerate a charging stall being blocked, and the value of the stall itself becomes a real line in the economics — which is an argument for time-based pricing and an idle fee rather than a bigger port count. Well above one stall per unit, parking is cheap, converting stalls costs you little, and the risk shifts to over-building ports that never fill.The pattern that survives both cases is the same: trench once for the eventual layout, install conduit and pads for the full count, and energise a fraction of the ports today. Civil work is the part you cannot cheaply redo.

Owners consistently model the energy and miss four other recurring costs, which is how a project that pencilled at cost recovery ends up an amenity by accident.The recurring stack is: energy at your commercial rate; the demand component of your tariff, billed on peak kilowatts rather than kilowatt-hours; a per-port network subscription if the chargers are networked; payment processing on every card transaction, which has a fixed per-transaction element that hurts badly on small sessions; and maintenance, which on outdoor pedestals in a public-facing lot includes vandalism and cable replacement.Of those, the demand charge is the one that surprises people, because it is not proportional to how much energy you sold. One unmanaged fast port can set a monthly peak that keeps billing after the car has gone. That mechanism has its own article — see the demand charges piece below — and it is the single most common reason a charging installation misses its projection.

If your average dwell is under two hours and your parking is abundant — the classic suburban strip centre, the grocery-anchored pad, the quick-service restaurant lot — stop reading the revenue pages. A ninety-minute session on a 9.6 kW port delivers under twenty kilowatt-hours at absolute best, and in practice well under that, because most drivers arrive with plenty of range and are not there to charge.At that throughput the margin on energy is measured in single-digit dollars per port per day before the network subscription, and the network subscription alone is likely larger. There is no price per kilowatt-hour that fixes this, because the constraint is time connected, not price.That does not mean do not install. It means install for the reason that is actually true — the tenant asked for it, the anchor lease requires it, it differentiates a leasing pitch — and budget it as an amenity from the start. An amenity that was budgeted as an amenity is a success. The same installation budgeted as a profit centre is a failure at identical performance.

If you land on amenity, size it small, price it to discourage stall-hogging rather than to make money, and put the money you saved on ports into conduit for later. If you land on cost recovery, the pricing decision matters more than the hardware decision, and the two are linked: selling by the kilowatt-hour has legal and hardware consequences that are decided months before the concrete is cut.If you think you land on profit, prove it before you spend. Measure real demand in the building rather than surveying for it, then model the revenue with your own tariff in front of you. Both of those have their own pieces below.One thing that does not change any of these answers: there is no federal tax credit on charging equipment placed in service today. Section 30C terminated on June 30, 2026 under Public Law 119-21. Any proforma still carrying a thirty percent federal line is overstating the return, and the correction is usually large enough to move a project between two of the three outcomes above. What remains is the state and utility layer, which is real in some territories and absent in others.
