Only 16% of U.S. fast-charging stations meet federal NEVI standards (open data)

Only 2,547 of 15,927 open public DC fast-charging stations in the 50 states and DC — about 16% — meet the federal NEVI station minimums, according to the US EV Charging Open Data catalog published by ChargingNear.me as of November 6, 2026. The same dataset, rebuilt daily from the company's live database of 58,164 charging locations and 273,246 ports, lists 881 stretches of U.S. highway where open public DC fast chargers are more than 50 miles apart, 22 of them in Colorado. The 20 free CSV and JSON files are released under CC BY 4.0, with station facts drawn from the U.S. Department of Energy's Alternative Fuels Data Center, and the 50-mile spacing benchmark traces to FHWA's NEVI guidance of February 10, 2022, which Colorado's 2025 NEVI plan retains even after FHWA's August 11, 2025 guidance left spacing to each state.

Where are the gaps between fast chargers on U.S. highways? The 50-mile line comes from FHWA’s NEVI guidance of February 10, 2022 https://transportation.org/ev/wp-content/uploads/sites/79/2023/05/90d nevi formula program guidance1.pdf , which counted a state’s Interstates as fully built out with a charger every 50 miles. FHWA’s guidance of August 11, 2025 https://www.fhwa.dot.gov/environment/nevi/resources/NEVI-Interim-Final-Program-Guidance-8-11-2025.pdf leaves spacing to each state. Colorado’s 2025 NEVI plan https://www.codot.gov/programs/innovativemobility/assets/colorado-2025-nevi-plan final.pdf keeps 50 miles. 23 CFR part 680 sets station minimums, not spacing. U.S. highway charging gaps over 50 miles Every stretch of Interstate and U.S. highway in the 50 states and DC, and of every other road FHWA designates as an EV Alternative Fuel Corridor, where open public DC fast chargers are more than 50 miles apart along the road.

Several states leave that signing blank in HPMS Texas, California, Maryland and Delaware among them , so a section’s signing also comes from FHWA’s National Highway System dataset, which records the posted route for the same HPMS route IDs. Sections of one highway in one state are joined end to end; a second carriageway or couplet drawn beside the first is dropped. Roads FHWA designates that are not Interstate or U.S. highways state routes, parkways, turnpikes use FHWA’s own corridor lines. Mile markers come from the route measure each state reports to FHWA in HPMS, where it runs continuously along the line state route measure . It often matches the posted mileposts it does for I-70 in Colorado but not always: some states measure from a different starting point or by section. Where the measure does not run continuously, such as one that restarts by county, the markers are miles from the south or west end of the line within the state from south or west end . Chargers are AFDC stations listed as open and public with at least one DC fast port, any network and any plug, including Tesla. A charger serves a highway when it is within 1 mile of it in a straight line. Chargers just across a state line count. We walk each highway from end to end and record every stretch longer than 50 miles between consecutive chargers, or between a charger and a state line, the Canada or Mexico border, or the end of the highway. Gap length is measured along the highway. Why 50 miles: FHWA’s February 10, 2022 NEVI guidance treated a state’s corridors as fully built out when chargers were installed every 50 miles along its Interstates. FHWA’s August 11, 2025 interim final guidance superseded it and leaves spacing to each state; Colorado’s NEVI plan CDOT and the Colorado Energy Office, 2025 update keeps a 50-mile target. 23 CFR part 680 itself sets no spacing. We use 50 miles everywhere so states can be compared. Corridor designation comes from FHWA’s Alternative Fuel Corridors map Round 8 , matched to the highway lines within 0.1 mile. A corridor named for another road counts only where that road has no line of its own there. Known limits - Straight-line distance to the highway, not driving distance to the exit. - Where two highways share the road, the line is drawn once, under one of them, so the shared miles appear once. - Chargers in Canada and Mexico are not in AFDC’s U.S. listing, so a gap ending at a border may be shorter in practice. - A charger listed as open in AFDC may be down on a given day; the gaps assume it works.

Two are in 23 CFR 680.106 FHWA final rule, February 28, 2023 for stations along designated Alternative Fuel Corridors: at least four ports with a CCS connector 680.106 b 1 and c , each able to deliver at least 150 kW 680.106 d 1 . The third, a location within 1 mile of a designated corridor, is the “within 1 travel mile” distance in FHWA’s February 10, 2022 NEVI guidance; part 680 itself sets no distance. Ports and power come from AFDC’s port-by-port listing. A port counts as CCS when it has a J1772COMBO connector, including Tesla ports with a CCS adapter that AFDC lists that way. A port counts at 150 kW when AFDC lists its CCS connector at 150 kW or more; a port with no listed power does not count. Corridor distance is the straight line from the station to the nearest designated corridor stretch ready or pending on the highway lines described for the gap file. Known limits - AFDC lists each plug’s top power, not what every port delivers while all four charge at once, so a pass here does not prove 680.106 d 1 ’s simultaneous 150 kW. - The test does not check the other parts of 23 CFR 680, such as 24-hour access, payment methods, uptime or networking. - “Within 1 mile” is a straight line, not travel miles from the exit.

A stretch from a NEVI-grade station to a state line, a border or the end of the highway meets it when it is 25 miles or less, so a station within 25 more miles past that point would keep the 50. A highway with no NEVI-grade station on it does not meet it. The 50-mile figure comes from FHWA’s February 10, 2022 NEVI guidance “every 50 miles” along a state’s Interstates for a fully built-out corridor .

Each is placed in a county by its coordinates, using Census TIGERweb county boundaries; ports are summed from those stations. Locations follow the site-wide rule ChargingNear.me uses everywhere: stations at the same place form one site, so a site counts once; a station not yet in a site counts on its own. Population is the Census Bureau’s Vintage 2025 estimate for July 1, 2025, from the table “Annual Estimates of the Resident Population for Counties: April 1, 2020 to July 1, 2025” CO-EST2025-POP, released March 2026 , read from its machine-readable twin co-est2025-alldata.csv, column POPESTIMATE2025. The county’s center point is the internal point the Census Bureau publishes for it in TIGERweb INTPTLAT, INTPTLON : a point inside the county near its center. We use it rather than the plain geometric centroid CENTLAT, CENTLON , which for counties with large water areas falls in open water; Honolulu County’s lies in the Pacific, hundreds of miles from Oahu. Distances are great-circle miles to the nearest open public DC fast station, rounded to a tenth of a mile. A county is a charging desert desert flag = yes when it has no DC fast port, or fewer than 1 public port per 10,000 residents. No EV registration column: no official source publishes EV registrations for every U.S. county, so the file ships population-based rates only. Known limits - Boundaries are simplified to about 200 meters, so a station right on a county line can land in the neighboring county. - A county’s center point can sit in open country or a national forest; the distance is from that point, not from where people live. - Puerto Rico and the other territories are not included.

Stations on AFDC’s Tesla and Tesla Destination networks are left out; every other network, and non-networked stations, stay in. AFDC writes the NACS SAE J3400 connector as TESLA. Where AFDC itemizes a station’s ports, a station is in the file only if a DC fast port has that plug a Level 2 NACS plug alone does not count . Where it does not, the station’s connector list decides, and the three port columns are left empty rather than guessed. Port columns count DC fast ports by the plugs each has. A port with two cables, such as NACS and CCS, counts under both, so the three columns can add up to more than the station’s DC fast ports. The by-network and by-state tables on this card are built from the same rows on the same day. Known limits - A NACS plug on a non-Tesla charger is often a NACS cable fitted to a CCS charger; AFDC does not say whether a Tesla can start a session without an app or adapter. - Facts are as AFDC publishes them; a network adding NACS cables shows up here once AFDC lists them.

Questions about this data Where are the biggest gaps between EV fast chargers on U.S. highways? As of November 6, 2026, the longest stretch in our highway gap file https://chargingnear.me/data us-highway-charging-gaps is 376.6 miles of US-2 in Montana, from Idaho state line to Tilleman Motors, Havre. The file lists 881 highway stretches where open public DC fast chargers are more than 50 miles apart. Colorado has 22 of them; its longest is 152.6 miles of US-160, from where US-160 meets I-25 to Kansas state line. What does NEVI-compliant mean? A NEVI-compliant station has at least four CCS ports that can each deliver 150 kW at the same time, under 23 CFR 680.106 https://www.ecfr.gov/current/title-23/chapter-I/subchapter-G/part-680/section-680.106 FHWA final rule, February 28, 2023 . FHWA’s February 10, 2022 guidance https://transportation.org/ev/wp-content/uploads/sites/79/2023/05/90d nevi formula program guidance1.pdf put stations within 1 travel mile of a designated corridor and every 50 miles; its August 11, 2025 guidance https://www.fhwa.dot.gov/environment/nevi/resources/NEVI-Interim-Final-Program-Guidance-8-11-2025.pdf leaves spacing to states. As of November 6, 2026, 2,547 of 15,927 open public DC fast stations in the 50 states and DC meet the port, power and distance minimums in our NEVI station check https://chargingnear.me/data us-nevi-station-check . Is there open data on EV charger reliability? Yes. Our reliability roll-up file https://chargingnear.me/data reliability-rollup gives the average and median Working-Now Score for each network, Colorado county and Colorado corridor whose stations have at least 10 driver reports in the last 30 days. As of November 6, 2026, no group has reached 10 reports, so the file has no rows yet. Drivers sent 1 report about public stations in the 30 days to that date. Which Colorado counties have the most EV chargers per person? As of November 6, 2026, Gilpin County has the most public charging ports per person of Colorado’s 64 counties: 1,630.2 per 100,000 residents, in our county file https://chargingnear.me/data colorado-counties . Summit County 799.6 and Pitkin County 745.9 come next. Among counties of more than 100,000 people, Boulder County leads with 250.5; resident counts are Census Bureau estimates https://www2.census.gov/programs-surveys/popest/datasets/2020-2025/counties/totals/co-est2025-alldata.csv January 2026 .
