Notes:

Figures are as of December of each year starting 2007. Before 2007, data were based on the federal fiscal year which was taken at the end of September.

2022 TOTAL count includes 573 Renewable Diesel stations.

2011-2013 Electric vehicle (EV) charging counts are an estimate of the number of station locations based on the number of electric vehicle supply equipment (EVSE) ports .

Beginning in April 2014, the EV data charging includes both the number of EV charging station locations and the number of outlets at each station. Please see https://www.bts.gov/browse-statistical-products-and-data/state-transportation-statistics/alternative-fuel-stations for counts of both EVSE ports and station locations.

Starting in January 2021, there is a jump in EV charging station counts in the historical datasets. This is due to the fact that the National Renewable Energy Laboratory (NREL) is transitioning EV charging counting logic to align with the hierarchy defined in the open charge point interface (OCPI) (https://evroaming.org/ocpi-background/) protocol: stations, EVSE ports, and connectors. With this transition, the number of charging outlets in the Stations Locator is being updated to represent the number of EVSE ports (or number of vehicles that can charge simultaneously) at a station location, rather than the number of connectors previously counted. The Station Locator still identifies the available connector types.

Description:

KEY: CNG = compressed natural gas; E85 = 85% ethanol, 15% gasoline; LNG = liquefied natural gas; R = revised; U = data are not available.

^a Total counts are the number of stations for all fuel types combine including both public and private non-residential stations.

^b Includes legacy chargers but does not include residential electric charging infrastructure.

^c Propane includes all (primary and secondary) stations.

^d Includes all outlets open to the public and selling gasoline.
