NEVI Formula Program: $5 Billion in Federal EV Charging Funds, State by State

The National Electric Vehicle Infrastructure (NEVI) Formula Program is the largest single federal investment in EV charging infrastructure in US history — $5 billion allocated through the 2021 Infrastructure Investment and Jobs Act, distributed to all 50 states plus Washington DC, Puerto Rico, and US territories based on lane-miles of designated Alternative Fuel Corridors and EV registration growth. The program's original mandate was to build DC fast charging stations at intervals of no more than 50 miles along designated highway corridors, primarily the Interstate system. That 50-mile spacing requirement was made advisory — not mandatory — under revised FHWA guidance issued August 2025, giving states flexibility to redirect funds toward rural roads, secondary highways, and medium/heavy-duty charging hubs once primary corridors reach build-out. The Joint Office of Energy and Transportation, a partnership between DOE and DOT, oversees spending plan approvals and compliance.

State spending plans were FHWA-approved starting in mid-2022, but actual construction moved significantly more slowly than most projections. By Q4 2024, only 31 NEVI-funded stations with 126 ports were operational across 9 states, according to the Joint Office's quarterly tracker. By mid-2025 that count had grown to approximately 57 stations and 384 ports across 15 states. The program hit a significant disruption on February 6, 2025, when the Trump administration froze NEVI fund obligations, halting new awards. Revised interim guidance issued August 11, 2025 allowed states to resubmit spending plans and access remaining FY22–26 funding, unlocking a resumption of new station development through the remainder of 2025 and into 2026. Three factors account for the broader gap between obligation and deployment. First, utility interconnection: DCFC stations above 150 kW require utility infrastructure upgrades that take 12–24 months to engineer and permit in many jurisdictions, independent of the station's own permitting. Second, state DOT procurement: states had to build procurement infrastructure, issue RFPs, and execute contracts with network operators — a process that took 12–18 months for most states, longer for those without prior EV charging procurement experience. Third, the 97% uptime standard: NEVI requires stations to maintain 97% annual uptime per port, which pushed network operators toward more expensive but more reliable hardware and prompted some to delay deployment until compliance monitoring systems were in place.

The NEVI technical standards are materially more demanding than typical commercial DCFC installations. Stations must provide a minimum of 150 kW per port, support both CCS1 (SAE J1772 Combined Charging System) and NACS (SAE J3400) connectors, accept credit and debit card payments without requiring account creation or app downloads, be located within one mile of an interstate exit, and maintain the 97% annual uptime threshold. The dual-connector requirement is particularly significant: stations installed exclusively with NACS connectors or exclusively with CCS connectors do not qualify for NEVI funding regardless of other compliance. This provision ensures NEVI stations serve the full range of EVs in the current market.

State performance varies considerably. Texas, Florida, and Colorado led on deployed ports through a combination of high funding allocations and streamlined DOT procurement processes. California and New York, which received larger total allocations due to higher EV registration counts and greater AFC mileage, moved more slowly through their own regulatory and environmental review processes — CEQA review in California added procedural requirements absent in most other states. Alaska and Wyoming received proportionally larger per-mile allocations and focused on the most isolated corridor segments, where NEVI-funded stations address genuine gaps in EV travel viability that no commercial market incentive would fill.

For EV drivers planning long-distance routes, the practical effect of NEVI deployment is most visible on major interstates. Significant portions of I-10, I-40, I-80, and I-90 now have NEVI-funded or NEVI-standard-compliant stations at compliant intervals, substantially closing the gap that existed on these corridors in 2022. Secondary Alternative Fuel Corridors — US routes and state highways — lag behind, and the Mountain West remains the region with the greatest remaining coverage gaps relative to driving patterns. The Joint Office's interactive map at afdc.energy.gov/corridors is updated regularly and tracks both AFC corridor designation status and NEVI-funded station locations, making it the most accurate planning tool for interstate EV travel in 2026.
