ROI & site fit
Payback in 3 to 5 years. The site decides where you land.
Three questions and thirty seconds gets you a number for a station your size. Send us the address and we score that exact site, then send you the report.

The same build under three levels of demand. How busy a station gets is what the site decides.
Compared with an ordinary station
Both stations sell the same electricity at the same price, so the revenue line matches. The difference is the power bill. An ordinary station buys everything from the grid; ours produces most of it on site from solar and storage.
| Ordinary station | ★ Volterra | |
|---|---|---|
| Investment needed | 1.3 bn ₫ | 2.6 bn ₫ |
| Revenue per year | 1.4 bn ₫ | 1.4 bn ₫ · identical |
| Grid electricity per year | -1.1 bn ₫ | -210 m ₫ |
| Profit after tax, year 1 | 89 m ₫ | 636 m ₫ |
| Payback | 14.4 years | 4.1 years |
| IRR over 15 years | 1% | 22% |
Figures for a typical site. A busier one does better and a quiet one worse, within the range above.
Cumulative cash flow, 15 years
The year a column crosses the zero line is the year that station has paid for itself.
What this estimate assumes
A standard configuration with no site rent deducted. The tool does not know the three things that matter most: how many cars pass your site, what the grid connection will cost you, and who is already selling electricity nearby.
Good numbers on paper still lose money at the wrong address.
Everything above assumes cars actually show up. That happens when there are enough drivers around the site, when a substation is close enough to connect at a sensible cost, and when nobody is already selling electricity next door. Miss one of those and the table above turns around.

The site alone shifts payback by
1.7 years
Same build, same budget, same region. The only thing that changed is how busy the station is.

The range is wide because we do not know your site yet.
Send the address and we run it again using the zoning on that parcel, land prices around it, and every charger within 3 km. What comes back is one number instead of a range.

Why the site decides
Three ways a good-looking site loses money
The cost of getting power there
A site can tick every other box and still fail because the nearest substation is a kilometre away. Medium-voltage cable over that distance can cost more than the chargers themselves.
Zoning, and the competitor opening next year
A busy corner today can be split three ways once two more stations open nearby. Or the parcel turns out to be zoned for something a charging station is not allowed to be.
Fast chargers where nobody is in a hurry
A DC charger costs nine times what an AC one does. Put DC in a car park where cars sit overnight and it stands idle most of the day. This is the most common way to spend a budget badly.
What gets analysed
Three layers before the score comes out
Every figure in the report says where it came from, so you can check it.
Space and demand
Where the cars are
- We lay a grid of cells over the area and score each one, so you can see where you stand inside your own neighbourhood.
- Road access, frontage, and whether a car can turn in off the street without a fight.
- Every charging point within 3 km: who runs it, how much power, how many bays.
Zoning and land
The condition that has to pass first
- Zoning read at your exact parcel, on every published planning layer.
- Asking prices for land around it, which is what the rent in the model is based on.
- An engineer reads this layer by hand. A zoning decision is a legal document, and matching keywords against the land-use name gets it wrong.
Financial simulation
The number you decide on
- How many chargers your budget buys, of which type, and what transformer rating they need.
- Fifteen years of cash flow, including tax, depreciation and the battery replacement in year 11.
- Three scenarios: a busy site, a typical one and a quiet one.
How scoring works
From an address to a decision, in four steps
You mark the spot
Pick the site on a map and tell us the budget. Under a minute, and no technical figures.
The engine scores it
Five weighted criteria (access, demand, anchors, distance to power, competition), normalised against a nationwide scale.
An engineer reads the plan
Zoning at your parcel and land prices nearby are looked up by hand.
You get the report
Score, heat map, competitor list, recommended build and a 15-year cash flow in three scenarios. It is yours to keep.
What you get
What arrives in your PDF report
A document with enough detail to take into a meeting with an investor or a bank.
A site score out of 100
With a rating of prime, strong, marginal or weak, and which criterion pulled the score down.
Heat map and competitors
Your rank among the cells around you, with the list of competing stations within 3 km.
Recommended build
How many AC bays, how many DC, which transformer rating, and what it all costs.
15-year cash flow
Revenue, grid cost, land rent and payback, in three scenarios, year by year.
The blocking conditions
Zoning, minimum budget and financial viability, each marked pass, fail or unverified. If a condition fails, the report says the site is not ready even when the score is high.

This tool gives a preliminary estimate for a standard configuration. The figures in your report are computed for your actual site. Neither one is a permit, a grid connection agreement or planning clearance. A final investment decision still needs a site survey and written capacity confirmation from the utility.
