Medium-voltage infrastructure for electric depots

Keeping your fleet moving starts with the right power infrastructure

The challenge behind your depot's power

Your charging strategy shapes what your infrastructure needs

Some depots rely mainly on overnight AC charging. Others need high-power DC opportunity charging to keep vehicles moving during the day. Most run a mix of both. 

That charging strategy determines what the medium-voltage infrastructure behind it needs to support.

A partner who understands your demands

Built on decades of EV infrastructure experience

Your infrastructure needs to match what your fleet actually does. That requires a partner with deep experience in both EV charging patterns and medium-voltage engineering. 

Only decades of EV infrastructure experience deliver the insight to understand your real operational demands, and build substations that handle them reliably. 

That's the difference between infrastructure that works and infrastructure that constrains your growth.

Trusted by leading fleet and charging operators

Complete MV delivery, from engineering to commissioning

01

Engineering

Every Alfen substation is engineered to your project's exact requirements. We design the right solution from the start, accounting for current needs and future capacity.
02

Manufacturing & assembly

Substations are built in-house at Alfen's facility in Almere. Full control over production means consistent quality and reliable delivery timelines.
03

Civil works

Site preparation, foundations, and cabling are coordinated by Alfen through trusted contractors. You don't need to source or manage a separate civil party.
04

Installation on site

We handle delivery and physical installation of the substation. Everything is placed, connected, and ready for the next phase.
05

Commissioning

Our team brings the installation live and verifies it meets all technical and grid operator requirements. One point of contact from delivery through to operational sign-off.
06

Electrical safety responsibility

We take formal responsibility for the electrical safety of the installation. The compliance paperwork and inspections are handled for you.

Grid connected walk-in transformer substation​

Built for depots with high power demand

  • Suitable for grid connections and transformer substations from 1750 kVA and 20 MVA
  • Flexible capacity: supports multiple medium-voltage and low-voltage configurations
  • Extra protection on and around the station.
Built-in IAC-AB safety technology.


Grid constraints shouldn't limit your growth

When your grid connection cannot provide the extra power your depot needs, expansion plans quickly stall.

Rooftop solar combined with battery storage lets you generate, store, and use more energy on site. The result: greater flexibility for your operations

Alfen has helped many logistics operators overcome capacity constraints with battery storage solutions, tailored to their energy needs.
