What ea.R Energieanlagen Ramonat does
ea.R Energieanlagen Ramonat GmbH is a family-owned German engineering services firm specializing in the planning, installation, and commissioning of high-voltage and extra-high-voltage cable systems for energy transmission infrastructure. Founded by Hubert Ramonat in 1999 (originating from a family trade business started over 30 years ago), the company is headquartered in Magdeburg with branch offices in Hannover and Vienna. Its core offering is cable laying certified for voltages up to 170 kV, complemented by specialized cable drum logistics (using GOLDHOFER heavy-lift transporters) and pipeline construction services. The company holds a comprehensive certification stack including ISO 9001, ISO 14001, ISO 45001, SCC, SCL, WHG, and EcoVadis.
The firm serves exclusively the four German transmission system operators—50Hertz, Amprion, TenneT TSO, and Transnet BW—and is engaged as a cable-laying contractor on all three flagship German HVDC corridor projects: A-Nord (~300 km), SuedLink (~700 km), and SuedOstLink (~540 km), collectively spanning approximately 1,540 km of transmission route. These projects form the backbone of Germany's Energiewende, transporting renewable energy from northern generation sites to southern consumption centers. Current leadership comprises Managing Directors Stefan Ramonat and Gökhan Edebali.
Revenue is generated through project-based professional services contracts awarded via competitive tendering to TSOs and large energy infrastructure clients, with no public pricing disclosed. The go-to-market is direct enterprise field sales to transmission operators, supplemented by an organic social and employer-brand presence (LinkedIn, Instagram, Facebook, XING) and participation in public construction-site events. The firm operates with over 100 certified specialists and reports market-leader positioning in German high and extra-high-voltage cable laying.
