[nb] Transformer Substations

Craftsmanship combined with decades of experience and innovative technology


Prefab transformer substations are our primary expertise. Alfen built its very first transformer substation over 50 years ago, and we have been working hard to equip them with the latest technological developments and innovative solutions ever since. Alfen transformer substations are tailored solutions, ensuring they provide matching answers to every situation and user profile. We take pride in the fact that we have delivered tens of thousands of stations to grid operators, industrial corporations and the horticultural industry.


  • Number one choice of grid operators

  • Casings made from premium quality concrete

  • Tailored solution for specific applications

  • Designs and tests compliant with IEC 62271-202

Accessible prefab stations


For situations that require more power and flexibility, Alfen delivers prefabricated accessible stations. We offer tailored stations to answer to the unique needs of every situation, but also empty casings to enable clients to create their own configurations. The modular construction of the prefab stations allow them to be used for virtually every possible application.

Compact Station


Alfen is an industry leader in the field of compact transformer substations. Over the years, the iconic Diabolo compact station became highly recognizable in many landscapes as grid operators have opted for this compact transformer substation on many occasions. The Alfen Diabolo is available in a large variety of capacities, which makes it the perfect transformer substation for every situation and application.

Special and customer-specific stations

Special and customer-specific stations

In addition to our sizeable portfolio of tailorable solutions, Alfen can also design specific solutions for electric infrastructure. In close cooperation with both grid operators and municipalities, we developed numerous customer-specific stations. One of the most iconic inventions is our design of the so called Peperbus (Pepper pot) transformer substation. This station has come to define many landscapes, such as the canals in Amsterdam, where it has a dual function as an advertising column. The custom stations developed by Alfen can either be used for electricity or gas.

Alfen transformer substations are perfect solutions to use during temporary projects. This provides for a reliable energy supply, while eliminating the need to invest in purchasing a substation. Alfen provides a complete solution for its clients by carrying out the entire advice and delivery process, by offering advice and carrying out the placement, assembly and connecting the station, while decommissioning the station and returning everything once the project is completed.
