Standard middle and upper sections Large Diameter Steel Tower (LDST) Combining innovative design with proven technology for improved reach with higher hub heights and a lower cost of energy. Vestas’ proprietary Large Diameter Steel Tower (LDST) technology combines proven steel construction with an innovative design to deliver strength and height. Easy transportation and quick installation contribute to excellent cost of energy. Reaching higher in low wind LDST is a simple, yet highly efficient way to harvest wind resources at low-wind sites. Higher hub heights increase the force exerted by the wind on the tower structure, which typically would require usage of thicker steel plates. Instead, LDST technology adds strength by increasing the diameter of the bottom sections without adding extra steel, reducing production costs, and ensuring at least 99 percent recyclability. Reaching higher with the LDST technology can result in up to 20 percent* higher Annual Energy Production (AEP). * Based on V126-3.45 MW®, hub height: 166 m (LDST tower) compared to hub height: 117 m (standard tubular steel tower) on a typical low-wind site.
