An Advanced Tower Systems (ATS) hybrid tower has connected to the grid in Grevenbroich, Germany. The lower section of the tower consists of narrow, concrete pre-fabricated parts. The upper portion is made up of conventional steel components. With its hub height of 133 meters, the system has an overall height of 180 meters.
‘This is a great day for wind energy,’ says Frans Brughuis, managing director of ATS. ‘Now the pilot project can demonstrate the high cost-effectiveness and efficiency of the ATS concept.’
The tower is constructed and operated by ATS Projekt Grevenbroich GmbH, in which juwi Netzwerk GmbH & Co. KG, Mecal Projects GmbH, Hurks subsidiary HB Bau GmbH and Siemens Project Ventures have equal shares. More than 20 ATS systems are being planned through 2010.
Compared to the widely used hub height of 100 meters, the ATS system achieves energy yields of about 20% more. The higher expenses for the tower construction will be redeemed in approximately four years, according to ATS.
