Knife River introduces a precast segmental concrete tower base extension.
Improve your energy yield by raising your hub heights to better
capture the wind’s energy. Knife River’s
base extension, combined with your steel tower, will increase
by 20 to 60 meters. The geometry of the precast system can be
modified to provide the
desired dynamic performance required for this hybrid tower.
Precast components can be shipped to the wind farm or cast on
site. High-performance concrete, post-tensioning and quality fabrication
will meet and exceed project expectations and construction schedules.
