Energieanlagen Ramonat GmbH (ea.Ramonat)

Energieanlagen Ramonat GmbH (ea.Ramonat) is a medium-sized, family-owned German company specialising in the construction and installation of electrical and energy systems. Headquartered in Magdeburg with an additional site in Hannover and a related company in Vienna, it delivers and installs electrical and energy installations of all kinds, including associated civil and construction pre-works. Its activities also cover specialised piping for cable systems, cable assembly and transportation, and road haulage including heavy transports, warehousing, cargo handling, forwarding – also internationally – and related logistics services. Founded as a small craft business by the Ramonat family and incorporated as a GmbH in 1999, ea.Ramonat has grown to over 100 employees. The company is certified and trained for cable installations up to 170 kV and has expanded into high-voltage and extra-high-voltage underground cable work, including 110/170 kV systems. It has a strong focus on connecting renewable energy assets to transmission networks, with more than half of its turnover at one stage generated from feeding wind and other renewable generation into the high-voltage grids of energy utilities. Reference projects include grid connections for a wind farm in Ireland, work on an offshore wind park off the Danish North Sea coast, and demanding mountain cable installations for Verbund Hydro Power in Austria. In 2024 the company reported revenues of around EUR 27.1 million. Ea.Ramonat acts as a specialist cable installation and logistics partner to major EPCs, manufacturers and TSOs on large HVDC corridor projects in Germany and Europe. It has been selected by NKT as a local subcontractor for logistics and cable installation on the SuedLink and SuedOstLink projects, and works in joint venture with Bohlen & Doyen on SuedLink cable laying and last‑mile logistics. With Sumitomo Electric, it is contracted to install 525 kV HVDC XLPE cables on Germany’s Korridor B project 49, building on two earlier joint projects. The company has invested in dedicated assets such as Goldhofer cable drum bridges for transporting cable drums up to 100 tonnes and specialised hydraulic cable pushers for challenging terrains, enabling cable installation over very long routes and in complex conditions worldwide.
