Energy Distribution
Holtab is innovative when energy distribution changes
Grid companies are facing challenges as electrification accelerates. For Holtab, this development has led to new collaborations and more innovative solutions.
Technical Buildings
Our Holtab Modular Indoor Concept (HMIC) is a prefabricated and cost-effective solution for technical and switchgear buildings. The stations are constructed, manufactured and inspected at our factory prior to delivery.
Prefabricated construction
All installation takes place in a safe, controlled environment – we deliver as close to a plug-and-play solution as you can get.
Rugged construction and design
The building is constructed of high-quality building elements without organic material, to ensure a long service life. The station meets the industry requirements for insulation, fire resistance, corrosion resistance and safety class.
Flexible concept
There is a wide range of standard dimensions to choose from, but the station can also be totally adapted to your requirements. The concept is based on 1.2 meter modules and the building can be fitted out using many different options.
HMIC – Holtab Modular Indoor Concept
You have great flexibility to adapt the station according to your preferences and requirements. The building can be equipped with a variety of standard options such as doors, stairs, entrance roofs, climate control, ventilation, recessed junction boxes, cable ladders, mounting plates for heavy equipment, anti-static floor mats, and more.
Technical building with insulated concrete slab
Insulated building on an insulated concrete slab for placement on a ground bed. Switchboard building up to a maximum height of 13.55 meters with heavy equipment.
Customisable
Solutions customised to requirements.
Plug and Play

Knowledge and inspiration
E-mobilityHoltab's expertise in demand as plug-in cars increase
In the transport sector, the development of electrified vehicles is going fast. “An e-revolution is happening right now,” says Carl-Fredrik Gyllenhammar, responsible for Holtab’s investment in electrified transport, e-mobility.
Business newsSchneider and Holtab revolutionise the substation
Together with Schneider, Holtab has developed a prefabricated 60/20 kV substation. European Energy in Denmark placed the order. "This is revolutionary," says Holtab's Country Manager for Denmark, Ebbe Klarskov.
