EV Charger and Robotaxi Charging Installation in St. Louis, MO

Level 2 chargers at 2.9 to 19.2 kW, under the Department of Energy's definitions, where cars stay for hours, and DC fast chargers up to 500 kW, which add 100 to 200+ miles in about 30 minutes.

Hotels downtown, office towers, apartments in the Central West End and Lafayette Square and staff garages at the medical campus suit Level 2. Fast charging fits retail along Kingshighway and Gravois, sites near the I-64 and I-44 interchanges downtown and fleet yards in the north riverfront industrial area.

We plan, permit, build and run the stations, and charging income shares a report with parking.

303 Level 2 and 78 DC fast ports at 130 public stations with St. Louis addresses, per Department of Energy data pulled Oct 14, 2026.

That count covers only addresses in the city proper; St. Louis County's suburbs add many more. St. Charles lists 27 fast ports and Chesterfield 26, both along I-64 and I-70 west of the city.

Our EV charging ports database tracks St. Louis monthly from the same federal source.

Ameren Missouri serves St. Louis. Its business EV program offers a free fleet electrification assessment, and we found no Missouri charger rebate listed when we checked.

The assessment is useful for a fleet owner: Ameren reviews vehicle routes and charging needs and estimates the load. For a hotel or office, the case rests on what guests and tenants will pay and on Ameren's commercial rate for the site.

Ameren reviews whether existing service can carry new chargers and designs any upgrade. We open that request first because it often decides the schedule.

An electrical permit from the Building Division, a contractor licensed by Missouri or the city, wiring to NEC Article 625 and an accessible stall following the U.S. Access Board's guidance.

Downtown, the CBD needs no off-street parking, so converting stalls to charging raises no count issue; elsewhere we check §26.52.030 first. A transformer pad may need zoning review. The division posts no review target; we plan three to six weeks, an estimate.

We draw the accessible stall before the rest, with a level route, reachable controls and room for a ramp.

Ameren's free fleet assessment and MoDOT's NEVI program, with $98.9 million for fiscal 2022–2026 covering up to 80% of eligible corridor station costs. The federal 30C credit cannot be claimed for charging property placed in service after June 30, 2026 (IRS, Instructions for Form 8911).

NEVI goes to stations on designated corridors, so a travel stop near I-70 or I-55 might qualify while a downtown hotel garage would not. The IRS instructions close 30C to new chargers.

Most St. Louis projects therefore stand on charging income and on what chargers do for occupancy and rents.

Ten Level 2 ports run about $38,000 to $85,600 installed in St. Louis, and two DC fast ports about $95,000 to $285,000, by Wins Parking's estimate.

Older garages downtown add cost for conduit through decks and limited panel room; surface lots spend it on trenching. Fast charging usually needs a new Ameren service.

We plan 8–16 weeks for Level 2 on an existing panel and 26–52 weeks for fast charging on new service. Costs scale national per-port figures and AFDC's installation guidance by the metro's BEA index of 95.1. Lot work fits the 5-month warm season.

From the software that runs the gates: Wins prices sessions, applies idle fees, monitors every port day and night, cites gas cars in EV stalls and reports charging and parking together.

Hotel guests charge overnight on their parking charge, and idle fees by day keep ports open for visitors. Faults page our operations desk for a remote reset or a technician. Monthly reports cover energy, uptime, income and citations.

This is our EV charging parking management service, paired with parking management in St. Louis.
