High plinth / pedestal foundation allows to reach higher hub heights when the tower is too short.This allows to increase the productivity of the wind turbine.

The idea of this foundation is to reach higher hub height with a high pedestal. The tower stands 3 to 6 meters above the «ground level». The tower does not experience any modification and the construction of the foundation does not require bigger cranes.

Ideally, this solution is combined with a longer anchor cage so that pedestal and slab are well connected in order to avoid cracking.

CTE Wind’s engineering team can provide the design for the anchor cage and also prepare the detailed anchor cage drawing.

The high plinth foundation is already tested and implemented in multiple projects in Europe and Latin America.

Catch faster and stable wind

Wind velocity at higher altitudes can be higher than at the soil. That’s why it is more beneficial to put the turbine high in the sky where there is more energy to extract.

The high plinth solution allows with his higher hub heights to catch faster and more stable wind speeds. But no only. By increasing the hub heights the wind turbine is able to carry larger and longer turbine blades. Wich mean greater aerodynamic efficiency for the same machine by keeping the same tower lenght.
