Policy support for non-residential charging infrastructure is crucial to increasing the fraction of overall miles traveled that are driven on electric power in Los Angeles County. The Southern California Association of Governments (SCAG) has been awarded grant funding from the California Energy Commission to plan investments in non-residential electric vehicle charging. A portion of that funding will be invested in workplace charging infrastructure for plug-in electric vehicles, specifically targeting an increase in the share of commute miles that are driven on electric power.

This report analyzes how charging infrastructure siting decisions impact commutes in Los Angeles County. It provides geographically-targeted investment recommendations for funding workplace charging infrastructure installations.

We identify alternative locations for investment (zones1) with sufficient numbers of plug-in electric vehicle commuters and insufficient numbers of existing chargers to warrant investment, narrowing the number of potential investment zones to 905. We apply two criteria to evaluate the identified zones: (1) potential to increase miles traveled on electric power and (2) environmental justice and investment equity.
