Mammoet has officially commenced work on constructing a new combined cycle gas turbine (CCGT) power plant in Altbach/Deizisau, Germany. The project, led by energy company EnBW, is a key milestone in the country’s transition towards greener energy, particularly the future integration of low-CO2 or green hydrogen by the 2030s. The plant, scheduled to begin operations in 2026, will initially switch from coal to natural gas, securing a continuous supply of electricity and heat to surrounding households and industries.
The choice of Mammoet as a core partner was largely driven by the company’s tailored engineering solutions and proven track record in power plant construction. Mammoet’s previous success in dismantling Block 1 of EnBW’s Neckarwestheim nuclear plant made it a natural fit for this complex operation. Their comprehensive service package for this project covers every aspect from just-in-time delivery and interim storage to the installation of crucial components like heat recovery steam generator (HRSG) modules, generators, turbines, and transformers.
In a statement, Andreas Franzke, Sales Manager & Segment Lead Power at Mammoet Germany, emphasized the importance of seamless coordination and innovative planning: “A completely new concept has been developed in close cooperation with the client and our project team. This means a secure energy supply, fewer interfaces and smooth processes on the construction site.”
One of the more innovative aspects of the project is the construction of a temporary jetty, recommended by Mammoet, to prevent congestion at the existing fuel loading point. The setup ensures that heavy cargo can be unloaded without disrupting the ongoing operations at the plant.
The heavy lifting operations will primarily rely on a 1,350-tonne crawler crane, strategically positioned to handle all significant components from a single location. In addition to the crane, self-propelled modular transporters (SPMTs), a customized gantry system, and specialized equipment will be employed to guarantee safe and efficient transport and installation.
“We are very pleased to be involved in this important construction project, which is part of the energy transition in Baden-Württemberg. It is a significant step into the future of using green hydrogen in facilities in Germany and beyond,” Franzke added.
The ongoing work is managed under the Sener Bonatti joint venture, marking another collaboration between some of the most respected names in industrial construction. The Altbach/Deizisau project is more than just another energy initiative; it is a significant leap forward in the region’s broader efforts to embrace cleaner energy and reduce reliance on fossil fuels.
