Complete MV substations solutions. From design to commissioning.
One partner for your MV projects. That makes all the difference.
Electricity demand is growing, grid capacity is under increasing pressure, and projects are becoming ever more complex. That calls for a partner who looks beyond the substation itself.
Alfen delivers complete medium-voltage solutions. From engineering and civil works to installation and commissioning, we provide reliable electrical infrastructure with a single partner managing the entire project from start to finish.

Didn't find the answer you were looking for?
That depends on how much support you need. We can take care of the entire medium-voltage (MV) scope, including engineering, manufacturing, civil works coordination, installation, commissioning, and electrical safety responsibility.
You stay in control of the customer relationship and any low-voltage (LV) work outside the agreed scope. We simply step in where you need us and work alongside your team.
Absolutely. Every project is different, so we tailor each substation to the site's requirements, whether that's the topology, capacity, layout, or specific technical requirements.
We start with a proven standard design and adapt it where needed. That way, you get the flexibility your project needs without reinventing the wheel.
We're still here when the project is finished. Alfen offers a range of service and maintenance agreements to help keep your customer's substation running safely and reliably.
Because we design and build the substations ourselves, our service teams know them inside out. That means faster troubleshooting and quicker support if something needs attention later on.
