Keystone Tower Systems Inc develops a new manufacturing process for tapered spiral wind turbine towers, eliminating transportation limits, enabling tall, low-cost towers that lift turbines into the faster, more consistent winds available at higher heights. This technology aims to reduce the cost of wind energy â potentially reaching grid parity in many locations â and enable wind development in many new regions. The company works with some of the largest turbine manufacturers and wind developers in the world to incorporate their product into plans, and are currently scaling up in order to implement a commercial system to produce towers 140m and greater in heigh
