Solano Electric Vehicle Transition Program

In 2015 the STA received a grant from the California Energy Commission to conduct the Solano Electric Vehicle (EV) Transition Program. This program seeks to identify and overcome barriers to the deployment of electric vehicles in Solano County through public outreach and education, a streamlined permit process for installing charging stations, and analysis of future charging station needs throughout the county. The goal is to help make it easier for those who want to own an electric vehicle to find resources and places to charge. Visit to find resources on the benefits of owning an electric vehicle, where to find charging stations in Solano County, information about the permitting process to install a charging station, and much more.

**UPDATE April 2018**: On April 11, 2018, the STA Board adopted the Final Report for the Solano EV Transition Program. The report can be viewed here.
