KGW Schweriner Maschinen- und Anlagenbau GmbH

What KGW Schweriner Maschinen- und Anlagenbau GmbH does

KGW Schweriner Maschinen- und Anlagenbau GmbH is a German B2B manufacturer specializing in tubular steel towers and complete internals systems for the wind energy industry. Founded in 1948 in Schwerin as VEB Schweriner Industriewerke to supply the Baltic shipbuilding sector, the company was privatized in 1993 and repositioned around wind-tower fabrication. It operates two production sites in Schwerin with roughly 68,400 sqm of outdoor storage and 43,900 sqm of hall and assembly space, processing approximately 20,000 tonnes of steel annually into 250 or more tower sections per year at diameters up to 4.5 meters, section lengths up to 35 meters, and weights up to 80 tonnes. The company also produces mechanical and electrical internals — access ladders, platforms, power supply, lighting, doors, vibration dampers, and service lifts — and offers a proprietary hybrid-tower pipe module system with pre-assembled fixing elements that allows installation without heavy cranes regardless of weather conditions. KGW has accumulated roughly 410,000 tonnes of processed steel into towers over the past 20 years.

The business model is project-based B2B contract manufacturing: customers (international wind turbine OEMs and wind farm developers) commission custom-engineered steel towers and internals against platform-specific specifications, with KGW delivering fully pre-assembled kits including transport logistics to wind farm sites. Pricing is not publicly disclosed and contracts are negotiated individually. The company is privately held, became part of the Wilms Unternehmensgruppe (Wilms Group) in 2006 for financial backing, and is led by Managing Director Johann Erich Wilms. Quality and welding execution are gated by ISO 9001:2015 (Lloyd's Register), DIN EN ISO 3834-2, EN 1090-1, and EN 1090-2 EXC 3 certifications across both Schwerin plants.

KGW serves a global customer base spanning the USA, Turkey, Belgium, France, Austria, the UK, Italy, Sweden, Ireland, Poland, the Netherlands, Ukraine, Romania, Japan, Vietnam, Argentina, and South Africa, with named reference customers including Nordex, Siemens Gamesa/AN Windenergie, Enercon, GE Wind, Suzlon, Senvion, Repower, PowerWind, Lagerwey Wind, Vensys, Kenersys, Gamesa, DeWind, eno energy, Fuhrländer, Prokon, EWT, TimberTower, Energiekontor, Wind Technik Nord, and eviag AG. Distribution is entirely direct B2B, with field sales led by Patrick Teichert and supported by a small management team of roughly six identified heads of function. The company employs approximately 100 people in Schwerin and participates in industry events such as the Day of Renewable Energies to support its commercial presence.
