ROI & site fit
Estimated payback in 3–5 years. The site decides your return.
Just 2 questions, about 30 seconds to estimate the returns on your charging station. Send us the address and we will assess the site and send you a detailed report.
Your project
What kind of site is it?
The charger mix and transformer rating are sized from your answers. Solar and storage use the standard block the site report assumes for every station.
Preliminary estimate

Cumulative cash flow, 15 years
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 ₫ | 3.0 bn ₫ |
| Revenue per year | 1.4 bn ₫ | 1.4 bn ₫ · identical |
| Grid electricity per year | -1.1 bn ₫ | -145 m ₫ |
| Profit after tax, year 1 | 89 m ₫ | 667 m ₫ |
| Payback | 14.4 years | 4.5 years |
| IRR over 15 years | 1% | 20% |
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 site report does deduct it, so the figures there are usually lower than the ones here. The tool also 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.
Same engine as the report. This page runs the exact financial model behind the site report — same formulas, same assumptions. The report simply knows your real address.
Good numbers on paper can still be wrong at the wrong site.
Every estimate rests on one assumption: EV drivers actually turn up to charge. That only happens when there are enough vehicles around the station, when customers are willing to stop, and when operating costs work out. Miss one of those three and the real return can land far from the projection.

Same build, same budget — only the site differs, and payback already differs.

Why the site decides
Three reasons a good-looking site can still underperform
Rent is not everything
A site with reasonable rent does not automatically perform. What matters is whether the location has enough customers and enough potential to generate revenue.
Planning can change everything
A change to infrastructure, traffic or zoning can significantly affect how the site trades and what it is worth in the future.
A busy road is not necessarily a good one
High footfall does not translate into customers. What matters is the right audience, the right need, and a fit with your business model.
What do we analyse?
3 layers of analysis before a score comes out
Every conclusion in the report rests on data and on criteria you can check for yourself.
Space and demand
Where to look, and how to look
- Which business model the site suits, and which customer profile it draws.
- How reachable, how visible and how convenient the location actually is.
- Comparable and competing sites within a 3 km radius.
Zoning and land
What can change what the site is worth
- Current zoning, read on every published planning layer.
- The impact of traffic, infrastructure and nearby developments.
- What could turn into an opportunity, or a risk, later on.
Financial simulation
Numbers that test whether it works
- The revenue the site has to reach to run profitably.
- Capital cost, running cost and how the investment comes back.
- Several scenarios compared, to judge how viable the site really is.
How does scoring work?
From an address to a decision, in 4 steps
You send us the location
Pick the site on the map or type the address. Under a minute, with no complicated data to prepare.
The system analyses and scores it
The location is assessed on several criteria: demand, accessibility, competition and the factors specific to that area.
Zoning is checked
Zoning and surrounding infrastructure are cross-checked to surface the opportunities and risks that could affect the site.
You get the report
A consolidated report with the score, the heat map, the competitor list and the projections that matter, to support your decision.
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.
