We are GRÄPER.
Technical building solutions for the modern utility industry
GRÄPER specializes in electrical engineering, technical building solutions, services and extensive energy projects at home and abroad. Our team comprises around 1200 engineers and skilled workers at our locations in Aachen, Ahlhorn, Almere, Euskirchen, Heiligengrabe, Marienfeld, Tostedt and Žilina. Together, we develop and manufacture tailor-made solutions for a wide range of customer requirements in the utility, energy and infrastructure sectors.
Building on our many years of experience, over the past decades we have gradually developed into a total solution provider for modern supply stations, transformer stations and air and gas-insulated medium-voltage systems. Equipped with state-of-the-art technical equipment, we implement reliable, economical and individually tailored medium and low-voltage systems for a wide range of customers. Depending on requirements, we can also implement extensive national and international energy projects.
On May 1, 2025, we integrated the Elley, Schürmann & Weber and AKA brands under the GRÄPER umbrella. GRÄPER realizes integrated solutions for energy infrastructure under one brand - from planning and production to commissioning and long-term support. Whether transformer stations, medium-voltage systems or retrofitting energy systems - GRÄPER thinks in terms of solutions, not individual parts.
With our innovative solutions, we have our finger on the pulse of the times and offer a solid basis for moving towards the future. We currently produce around 4,500 stations a year, 75 percent of which are fully equipped and ready for connection.
Thanks to the size of our company, we are always in a position to handle large quantities of extensive inquiries. However, we are just as strong when it comes to individual solutions.
