The question of whether it’s possible to make a profit from a public charging station continues to hang over the electric vehicle (EV) charging industry. The challenges are threefold:
- The costs of the EV charger and installation, which remain fairly high.
- The utilization rate; i.e., how many plug-in electric vehicles (PEVs) are actually using the chargers each day.
- The question of what PEV drivers are willing to pay for the charging.
Level 2 charging is still the most widespread type of installation deployed in public charging, and a back-of-the-envelope payback model shows that it is possible to receive a reasonable return on investment (ROI) for a Level 2 charger with high utilization and the right price point. A networked Level 2 charger with two plugs typically costs around $5,000–$6,500. Installation costs vary significantly, but can easily double the upfront investment by the site host. Operating costs are actually quite low. The electricity used is not a major cost factor, even at a relatively high cost of $0.13 per kWh (as in California, for instance). Typically, the site host will pay monthly services fees to a network operator. In some cases, it will share revenue with the operator, as well.
Just in Case
It’s important to note that there are only so many hours in the day that a public charger is going to be both accessible and likely to be used. If a dual public charger can reach utilization of around 10 charging sessions per day, and charge $2 per session, the host could make back the initial investment in 5 to 6 years.
This picture is a little rosier than the reality today, simply because the current rate of usage of public chargers is nowhere near 10 charging sessions daily. Nevertheless, this simple ROI model demonstrates that there is a pathway to profit for offering public charging services. However, there is a real question as to how many drivers will be willing to pay $2 for around 20 miles of charge, which is what a typical battery electric vehicle (BEV) driver may get from a single charging session. Given that this should cost them less than a dollar when they charge at home, it’s not clear that Level 2 public charging will ever be much more than a just-in-case opportunity for drivers. This will be even more accurate as we see affordable, longer range BEVs come on the market, since the need to top up during the day will be lessened.
Keeping It Free
These economics are one reason why many businesses will continue to offer public charging as a free service, figuring that there’s more benefit from using the chargers to attract customers, and keep them shopping longer, than to collect charging fees. It’s also why public charging manufacturers are offering leasing or no money down, no interest financing to keep the upfront cost from being so daunting.
According to Navigant Research’s new report, Electric Vehicle Charging Services, global revenue from EV charging services is expected to grow from $81.1 million annually in 2014 to $2.9 billion by 2023.

EV charging is a promising new, multibillion-dollar business sector. These forecasts include revenue from DC charging, which is likely to be a more lucrative segment than Level 2. But our scenario also assumes that some public charging will remain as a free perk, rather than as a direct revenue generator, given the questions that linger about drivers’ willingness to pay for top-up Level 2 charging.
