Design of wind turbine foundations

Based in Dinard (Brittany, France) with subsidiaries in Germany (Freiburg im Breisgau), Poland

(Warsaw), Portugal (Lisbon), Brazil (Porto Alegre) and Vietnam (Hanoi), CTE Wind Civil

Engineering is an experienced design office specializing in the analysis and design of

onshore wind turbine foundations. We propose the following services for our clients:

Assistance, consulting and expertise

Preliminary and final designs

Static and dynamic analyses

Research of economical and optimized foundations

Seismic analyses

Site inspections for reinforcement

Our designs are adapted to the geotechnical reports and respect the criteria of

manufacturers, the requirements of the clients as well as the standards both of the country

concerned and specific to the wind energy sector.

We have found foundation shapes that result in a better formwork and make transportation

and positioning of reinforcements easier so that we can propose to our clients foundations

which are economical, optimized but still reliable.

Our know-how

Facts and figures :

Participation in the design of up to 670 wind

farms in France and abroad

More than 4800 foundations studied, with a

total turbine capacity of 8600 megawatts

CTE Wind

Photovoltaic

For photovoltaic systems (PV) on the ground CTE has developped an expertise in the design

of the foundations and the verification of the supporting steel structure for the PV panels.

We provide expertise in the design of foundations for all types of ground-based photovoltaic

panel projects.

Our studies are adapted to the geotechnical conditions of the site and to the connection

system of the steel structure.

We also take into account the local and international standards as well as specific guidelines

which can be applied to large fields with photovoltaic structures.

We have worked for several clients, installing different types of trackers and modifiable struc-

tures on difficult terrain and old landfills.

“TOUL-ROSIERES” SOLAR FARM

Location: Toul-Rosières Air Base, France (54)

Year: 2011 (in progress)

Client: Krinner Schraubfundamente GmbH

Manufacturer: Krinner Schraubfundamente GmbH

Site manager: EDF EN

Superficy: 400 ha, 143 MW


For this solar farm CTE performed the preliminary design and implementation studies for

the panel structure.


The project was divided into 5 panel units of 12 MW each. The calculations were adapted

to the geotechnical conditions of each panel unit

The PV panels are fixed in the ground with screws (no foundation)
