Utilization case
$294,834 per DC fast stall, with the Level 2 ports and all the shared work folded in, against the flat $55,000 a post this model used before. The published benchmarks put an all-in fast charging port at $79,199 on 2021 cost data, rising to about $157,000 by 2030, and the value many state corridor plans use is $375,000 a port for a four-position 150 kW station. This configuration lands inside that range, because it carries 1247 kW of simultaneous charging power, which drives a 2500 A service and a 2100 kVA transformer, and the trench is a measured 129 ft. Charging hardware is 17% of the total, against the 10% to 30% the cost literature reports, and the whole installed cost is 6.0 times hardware, against the 3 to 5 times it reports for US projects.

Corridor sites only; 4 ports × 150 kW minimum.
Charging equipment is 5-year MACRS property; bonus depreciation per current tax law

In plain words
Six signals, each 0 to 100, weighted Traffic 25, Competition 20, Dwell 15, Demand 15, Visibility and access 15, Site readiness 10. Traffic scales the frontage road's daily count from 2,000 (0) to 30,000 (100). Visibility adds frontage stalls (up to 50 for 10 or more), entrances drawn (15 for one, 25 for two or more) and the distance from the stalls to the road centreline (25 within 100 ft, fading to 0 at 300 ft). Dwell weights the places within half a mile by how long they hold a driver (supermarkets and hotels 4, restaurants and gyms 3, pharmacies 2, other shops and banks 1; places within a quarter mile count double) and saturates at 80 points. Demand blends tract median household income (45%), population density (35%) and the EV share (20%). Competition starts at 100 and loses 12 per DC port within a mile and 4 per further DC port within three miles; a busy road with no fast charging within three miles scores 100 as a gap. Readiness counts confirmed stalls toward the 10-stall grant configuration, placement issues in the saved layout, power nearby and the zoning verdict.
Expected kWh per port per day starts from published regional averages for public fast charging and is multiplied by site factors: frontage traffic, things to do nearby, competing chargers, local EV adoption, parking demand seen across the survey flights, visibility and charger power. The p10 and p90 bound the estimate; confidence reflects how many of those inputs the site actually has. Year one starts at a share of steady state and ramps up over the first years, then grows and saturates.
Not an allowance any more. The cost is built up line by line — equipment, electrical, civil, labour and soft costs — each with a quantity, a unit cost and a note saying whether the figure came from a seller's price, from published cost, wage, tariff or fee data, or from a stated build-up where nothing public exists. The trench length is measured on this site's own survey, routed from the building's electrical service point round the building footprint to the equipment pad and the charging row, and the share of it crossing pavement is measured too, because that is what carries a saw cut and a patch. The service size falls out of the connected load at 125% for a continuous load, and the feeder, the conduit, the switchgear and the transformer are sized from that. The full itemization, with every line editable, is on the pro forma page.
Revenue is ports times kWh per day times price times 365, scaled by the ramp. Cost is the energy charge per kWh, the demand charge on the billing peak, the network services fee on DC energy (escalating) and a flat upkeep charge per L2 unit. The demand charge matters more than anything else here: it is billed on the highest half hour of the month, a single car charging alone already puts the site near its floor, and at the filed rates it can be a larger line than the electricity itself. A battery is sized to shave the top off that peak and its saving is shown as a revenue line. Year 0 is the itemized cost less cash grants, the federal charger credit and the federal investment credit on the battery. Taxes: the basis is gross cost less the whole charger credit, less half the battery credit, and by default less grants; bonus depreciation expenses most of it in year one and the rest follows 5-year MACRS; tax is the rate times net less depreciation, so early years produce a shield. NPV is discounted at the rate set above; payback is interpolated within the year the cumulative turns positive.
Grant line items apply each program's rules to the layout: per-unit amounts, unit caps and program caps, by charger type. The two federal credits reduce the depreciable basis by different amounts, and both rules are implemented as written: the charger credit by the whole credit, the battery's investment credit by half of it. Lines marked verify are curated from program pages and should be confirmed against the current solicitation before relying on them.
Only public signals are used: public traffic counts, the public station registry, map amenities, census tract data, state imagery and this portfolio's own survey. No proprietary charger reliability or utilization data. Treat the score as a ranking aid between your own sites, and the pro forma as a model of stated assumptions, not a forecast.
