The Frozen Map: How Repealing the IRA & Tax Incentives Permanently Locks in the Charging Divide.

The transition to electric vehicles is often framed as a question of consumer choice. Will Americans buy them?

The new administration has moved on two fronts to dismantle the electric vehicle ecosystem.  In Congress, the reconciliation bill known as the One Big Beautiful Bill Act repealed the core EV tax credits that drove consumer demand, including the Section 30D credit worth up to $7,500.  At the same time, the White House issued executive orders freezing the National Electric Vehicle Infrastructure Formula Program (NEVI) formula program, pausing state charging plans without a defined restart date.  Together, these actions halt both demand-side and supply-side federal support.

What does a strictly market-driven infrastructure map look like?

At Ozean, we analyzed National Renewable Energy Laboratory data covering more than 82,000 public fast charging ports (plugs), mapped against congressional district boundaries. The results suggest that without federal intervention, the national charging network will not merely slow. It will harden into a long-term equilibrium.

Using a 20-mile buffer, a standard metric for reliable highway access, we identified “Charging Deserts,” defined as any land area >20 miles from a public DC Fast Charging location. The resulting map shows a stark divide across the country. 

Our map visualizes “Charging Deserts,” defined as areas more than 20 miles from a fast charger.  The data reveals a massive vertical split along the 100th Meridian.

• The Reality: In districts such as Montana’s 2nd and Nevada’s 4th, roughly 70 to 80 percent of total land area qualifies as a charging desert.
• The Policy Impact: Private charging networks do not deploy infrastructure in these districts for a simple reason.  Sparse population density does not support a viable return on capital.  The IRA’s EV tax credits and the NEVI formula program were designed to offset that structural gap by subsidizing routes the market ignores.
• The Consequence: With EV tax credits repealed in statute and NEVI grants paused pending administrative review, these rural districts are no longer in a buildout queue.  They face a locked-in absence of infrastructure.  Market forces alone offer no corrective mechanism. 

The Demand Collapse, The Urban Core

In dense urban districts, coverage is not the binding constraint.  Capacity is.

Our analysis identified districts like NY-14 (Rep. Ocasio-Cortez) and AZ-03 (Phoenix) where there are over 10,000 residents for every single fast plug.

• The Reality: These are “garage orphan” districts. A high share of residents live in apartments and depend on public charging.
• The Policy Impact: Repeal of the Section 30D tax credit removes the primary mechanism that made EV ownership viable for working- and middle-class buyers.  Economic modeling suggests lower adoption rates under this policy environment, followed by reduced private capital investment in charging infrastructure.
• The Consequence: Charging networks site capital where utilization forecasts justify deployment.  A contraction in EV adoption among renters in the Bronx or Phoenix undermines that case.  Planned installations in these neighborhoods become the first projects cut.  Capital flows retreat toward affluent suburbs with private garages, leaving dense urban districts with aging and insufficient infrastructure.

The Political Paradox

The districts most exposed to the loss of federal EV support fall into two categories.  Vast rural charging deserts across the Mountain West, the Plains, and the deep Sputh, and densely populated urban districts with limited private charging access.

These regions are largely represented by the congressional majority that supported repeal of the EV tax credits and administrative retrenchment of federal infrastructure programs.

A shift to a pure market allocation model channels investment toward areas already profitable.  Wealthy suburban districts and major interstate corridors receive continued attention.  Rural America and working-class urban neighborhoods fall outside the investment frontier.

Conclusion

The map produced in this analysis was intended as a federal deployment roadmap.  With repeal of the IRA’s EV tax credits and suspension of NEVI implementation, it now resembles a likely final state.

A private-only market will reliably serve the roughly 57 percent of districts that already meet profitability thresholds.  The remaining 43 percent, concentrated in the rural West and the urban core, face a closed bridge to the next phase of the transportation system.
