How many EV chargers should my building have?
The right number of EV chargers depends on demand forecasting and cost-benefit analysis specific to your site.
Determining the right number of EV chargers requires balancing two key variables: demand and cost.
Demand side: Estimate how many electric vehicles will be on-site at any given time and how often they need charging. This varies dramatically by building type — a fleet operation has different needs than an office building or retail center.
Cost side: Level 2 chargers typically cost $10,000 per unit installed, including electrical upgrades. DC Fast Chargers (DCFC) are significantly more expensive due to power requirements. Electricity costs can be subsidized by building owners or passed to EV drivers.
Revenue opportunity: In high-traffic destinations (shopping centers, airports, highways), leasing DCFC spots to charging operators can generate $2,000–$10,000 per spot annually.
Start with a demand assessment of your building's EV usage patterns, then model the cost-benefit of different charger quantities and types to find the optimal solution.
