What to know about charging in St. Helena
St. Helena's charging landscape is heavily influenced by Tesla Destination, which accounts for 73% of the city's 37 public charging locations. This concentration reflects a unique opportunity and challenge for site developers, as the reliability and pricing of charging options are largely dependent on a single operator. With only 3% of the public locations offering DC fast charging, the city’s infrastructure leans towards Level 2 options, catering to longer dwell times. However, the single DC fast charging station boasts an impressive average power of 325 kW, positioning it among the fastest available. New entrants introducing high-capacity hardware in the 150–350 kW range will likely stand out, especially when considering driver preferences in navigation apps.

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.
