EVwire brief: Tesla has published a guide showing Supercharger for Business hosts how higher Supercharger site utilization increases their profits. Tesla notes that going from one charging session per stall per day to five alone could cut a site's average energy cost by more than half.
Most of a Supercharger for Business site’s commercial power bill is predictable, such as fixed meter fees, supply costs billed per kWh, delivery charges and taxes. The wild card is the demand charge, which is based on a site's single highest power draw (kW) in a billing period rather than the energy (kWh) it uses.
Demand charges are often the priciest line on the bill, and Supercharger sites can't easily dodge it, since one vehicle can pull a big chunk of a cabinet's capacity and drivers tend to roll in at the same time.
Plus, once that monthly peak is set, it's locked in. Every session that charges under it adds energy costs but little to nothing to the demand charge. So the more cars a site serves, the thinner that fixed charge gets spread across each kWh, a concept Tesla calls demand charge dilution.

The difference shows up fast. A site that sees only a few sessions per stall per day spreads its demand charge over very little energy, so its all-in cost per kWh stays high and eats into margins.
As traffic climbs, that cost drops toward the base energy charge while the host's retail price stays put. The gap between the two is the host's profit, and it grows the busier a site gets.
Livio Caputo, who works on Supercharger for Business at Tesla, shared the guide on LinkedIn and said more insights and educational tools are on the way. He also highlighted Tesla’s Supercharger for Business financial calculator, which helps potential hosts compute their site’s costs.
Interestingly, when an X user noted that anyone who doesn't already know what demand charges are has no business buying a Supercharger, Tesla Senior Director of Charging Max de Zegher replied that the guide is meant as a reality check for would-be hosts:
That's why we publish guides like this. We almost anti-sell Supercharger for Business and now walk buyers through why it might not be right for them. But if you're investing in charging, Superchargers are by far the best, lowest risk and easiest option.
By the way, it sure looks to us like you are an EV geek like ourselves.

Context:
Tesla launched Supercharger for Business in 2025, letting third parties buy, own and operate their own Supercharger sites. Hosts fund the installation, pay for electricity and set their own prices. Tesla supplies the hardware, runs the software and keeps the sites maintained for a fee.
The program has been picking up hosts of all sizes. EVgo is rolling out EVgo Superchargers across the US, while Roam Energy has brought sites online in Prattville, Alabama and Statesville, North Carolina.
Some hosts are also working to draw more drivers to their stalls. Electric Son's Houston site pairs four V4 posts with an all-electric coffee truck on weekdays, and United Chargers Network has built EV Charging Lounges to give drivers somewhere to spend their charging time.
