Start of Construction for the TenneT Grid Booster in Audorf

Feb 18, 2025
Audorf, Germany -

The ground-breaking ceremony marked the start of construction of one of the first grid booster plants in Germany. Together with TenneT, Schleswig-Holstein's Energy Transition Minister Tobias Goldschmidt, Fluence and Osterrönfeld's Mayor Hans-Georg Volquardts, the symbolic ground-breaking ceremony was held for the innovative project at the Audorf-Süd substation.

What makes the grid booster so remarkable?

The system combines state-of-the-art grid control technology with a powerful battery storage system that is connected directly to the Audorf substation. As a result, the electricity grid is utilised more efficiently, fluctuating wind and solar power can be better integrated and fewer grid bottlenecks occur. Conse­quently, the grid can accommodate more renewable energy, reduce costs for grid inter­ven­tions, and increase the trans­mis­sion capacity of existing power lines.

 

Our role at CDM Smith: Civil EPC for a future-proof infrastructure

We supported the project from the very beginning. As a Civil EPC partner (Engineering, Procurement & Construc­tion), we are responsible for the entire structural realisation of the engineering structures of the grid booster. This includes:

  • Building construc­tion: planning and construc­tion of the buildings for the technical infrastructure

  • Civil engineering & earthworks: foundations, cable routes and necessary development measures

  • Concrete construc­tion: supporting structures for a safe and durable system

Philip Pens (Project Manager), Lukas Wallrabe (Customer Manager at Fluence) and Andreas Roth (Environment/Energy Division Manager) were there live at the start of construc­tion and are supporting the project with their expertise.
