FAQ

You’ll need a high-voltage station (also called a medium-voltage or transformer station) whenever your site’s power demand goes beyond what the standard low-voltage grid can supply. In practical terms, if your total load is above ~100 kW, most utilities will require a dedicated high-voltage connection to feed your project. So if you’re planning multiple fast chargers or any other heavy electrical load, chances are a high-voltage station will be mandatory to safely provide that level of power. We can help determine this during the planning stage and will handle the high-voltage setup if it’s needed.

High-voltage connections let you pull in a lot more power, which is essential for large EV charging hubs or fleet operations. One big advantage is lower electricity rates – high-voltage users often pay less per kWh, so your energy costs drop. A high-voltage infrastructure is also more robust and future-proof: it gives your site plenty of headroom to add even more chargers or other energy-intensive systems later without major rework. In short, it’s a bigger up-front investment, but it enables efficient, large-scale charging with better long-term economics.

Faster than many expect. The exact timeline depends on the utility and equipment lead times, but generally once we have the design approved, the longest part is waiting for the transformer station components to be built and delivered (around 14 weeks lead time is common). We often do all the ground works and preparations while waiting for the equipment, so nothing sits idle. When the high-voltage cabin and transformer arrive, our team moves quickly to install and connect them, which usually only takes a few days to a couple of weeks. We also test everything thoroughly before switching it on. In some cases, we might have a standard station design in stock, which could cut the timeline significantly. Overall, we manage the schedule tightly to get your high-voltage supply up and running as soon as possible.
