NEVI Charging Gaps: What Limited Public Charging Costs EV Drivers
By Morgan Ellis · Published Jul 16, 2026
Direct Answer
Limited public charging can add about $808 a year to the charging bill of a driver who travels 12,000 miles and cannot charge at home. Using GearUp's national baselines and a 3.5 mi/kWh EV, all-home charging costs about $632 a year, while all-public DC fast charging costs about $1,440. An apartment or condo driver who can charge only 20% at home pays about $1,278 a year—$646 more than an all-home driver. That is why NEVI is an ownership-cost issue, not just an infrastructure headline.
GearUp Calculation: What Public-Charging Dependence Costs
Source: The U.S. residential electricity baseline is 18.44¢/kWh from EIA Electric Power Monthly, Table 5.6.A (May 2026). The public DC fast-charging baseline is 42¢/kWh from AAA (August 6, 2026). We use the site's standard 12,000-mile annual mileage and an illustrative 3.5 mi/kWh EV. EPA efficiency is measured from the wall, so we add no separate charging-loss factor.
Calculation: Annual electricity needed = 12,000 miles ÷ 3.5 mi/kWh = 3,428.6 kWh. Annual charging cost = 3,428.6 × [(home share × $0.1844) + (public share × $0.42)].
| Charging access | Annual cost | Extra vs. all home | 5-year extra cost |
|---|
| 100% home | $632 | $0 | $0 |
| 80% home / 20% public | $794 | $162 | $808 |
| 50% home / 50% public | $1,036 | $404 | $2,019 |
| 20% home / 80% public | $1,278 | $646 | $3,231 |
| 100% public | $1,440 | $808 | $4,039 |
Driver impact: At these rates, moving from all-home to all-public charging raises energy cost from 5.3¢ to 12.0¢ per mile—a 128% increase. Public charging does not automatically erase every EV saving, but it can remove more than $4,000 from the five-year advantage.

The Apartment and Condo Scenario
A driver with assigned home charging can plug in overnight and buy nearly all energy at the residential rate. A renter or condo owner without a dedicated outlet may depend on workplace charging, retail chargers, or DC fast charging. In the 20%-home scenario above, that access gap costs about $54 a month or $646 a year compared with all-home charging. At 100% public charging, the gap is about $67 a month or $808 a year.
Convenience is separate from the dollar total. A nearby station can still require a detour, a wait, or a backup stop when ports are occupied or unavailable. Before buying, map the chargers on recurring routes, check recent uptime reports, and price the network you would actually use. A federal allocation or a planned station is not usable charging access.
Why NEVI Changes the Ownership Math
Source: The National Electric Vehicle Infrastructure Formula Program was created under the 2021 Bipartisan Infrastructure Law with $5 billion for fiscal years 2022–2026. The official DOE Alternative Fuels Data Center says NEVI can cover up to 80% of eligible project costs. Chargers must be publicly available, support open-access payment, and initially serve designated Alternative Fuel Corridors; states may propose other public roads after their corridors are certified as built out.
The rollout has been much slower than the funding headline implied. Reporting cited in the original version of this article found about $3.3 billion allocated to states by early 2026, roughly $670 million awarded to projects, and fewer than 400 operational ports from NEVI and the related Charging and Fueling Infrastructure program combined. Those figures describe program progress—not the size of the entire private charging network.
Calculation: A new reliable public option matters most when it changes a driver's charging mix. For the representative driver, shifting from 20% home charging to 50% home or lower-cost charging access cuts annual cost from $1,278 to $1,036, a $242 annual saving. Moving from all-public dependence to an 80%-home-equivalent mix cuts annual cost by about $646. The value of a station therefore depends on its price, reliability, and location, not simply on whether it was funded.
Driver impact: NEVI can lower total ownership cost indirectly by giving no-home-charging households more competition and more usable alternatives to premium-priced fast charging. It can also reduce route risk. But until a station opens on a route a driver actually uses, it should not be counted as a saving in an EV budget.
What NEVI Was Designed to Fix
NEVI's purpose is a connected highway fast-charging network rather than cheap residential charging. The program targets corridor gaps that make long trips difficult and requires public access and non-proprietary payment. Updated federal rules also allow states with completed corridors to direct funding toward other public roads and locations.
That scope matters. Even a successful highway buildout does not give an apartment resident an overnight charger. It can improve road trips and add local competition where sites are convenient, but building-level or workplace charging still determines whether most daily miles can be bought at home-like rates.
A Practical Buying Test
- List your real charging locations: home, work, weekly errands, and frequent highway routes.
- Assign a realistic share to each: do not use the national home-charging average if you lack a dedicated outlet.
- Use posted prices: public rates vary by network, membership, location, and time.
- Calculate the five-year access penalty: annual blended cost minus all-home cost, multiplied by five.
- Treat planned NEVI sites as zero access until open: verify location, connector compatibility, price, and recent reliability.
If the public-charging premium makes the EV unattractive, test a workplace-charging agreement, a building installation, or a different vehicle—not a more optimistic charging assumption.
