Keystone Tower Systems has completed the manufacture and installation of the industry’s first tapered spiral welded wind turbine tower in Middleton, MA. The tower was made using Keystone’s novel manufacturing process which produces tapered, tubular steel towers with variable wall thickness – the standard design for the wind industry. This fully-automated rolling and welding system…

As the wind industry has matured, turbines have grown larger and the cost of wind energy has been driven down. Further growth today, however, is not possible due to transport constraints for the tower. Today’s tower designers are forced to choose between: Short towers (less than 100m) that give up 30 to 50% more energy…
