Start of Construction for the TenneT Grid Booster in Audorf

Start of Construction for the TenneT Grid Booster in Audorf
18 February 2025
TenneT, Fluence 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:

  • check Building construc­tion: planning and construc­tion of the buildings for the technical infra­struc­ture
  • check Civil engineering & earthworks : foundations, cable routes and necessary development measures
  • check 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.
