The AirBASE, an innovative partially-precast foundation for Wind Turbine Generators (WTG) was patented in December 2018. Since then, HWS has studied its feasibility in different scenarios, covering a wide power range of TURBINES (from 2.X MW to 5.X MW), SOIL properties as well as TOWER heights from 90 m to 165 m, made in both […]
