Nearby cities with EV charging coverage
Other cities in California we cover with full charging data and site profitability scoring — useful for comparing footprints across the state.
Every score on EV Data Map blends location demand, competition and operating economics into a single 0–100 number. Demand is modeled from registered EV count, commute and through-traffic patterns, daytime worker population, retail and hospitality footprint, and tourism inflows. Competition uses the count and quality of nearby existing chargers — including DC fast power, network reliability and dwell-fit. Operating economics include estimated electricity tariffs, demand-charge exposure, expected utilization, and capital cost for the recommended hardware mix.
For St. Helena specifically, our model accounts for local commute corridors, nearby interstate and US-highway traffic, the existing footprint of 1 DC fast and 36 Level 2 sites, and the typical dwell profile of the surrounding land use. The result is a per-address score plus a recommended configuration — number of stalls, target power level and network — that maximises projected revenue.
