Keystone Tower Systems Builds State-of-the-Art Wind Turbine Tower Manufacturing Facility in the US

Denver, CO, USA - February 6, 2020 – Keystone Tower Systems, Inc. has started construction on its first full industrial-scale tower manufacturing plant in the U.S. The facility will have the capacity to produce towers for wind turbines representing over 1 gigawatt of energy production per year.

The facility utilizes Keystone’s proprietary spiral welding process, enabling fully automated tower manufacturing at ten times the speed of a conventional tower factory, and with substantial improvements in quality and consistency at a lower cost. The facility, built with support from National Oilwell Varco (NOV), will begin production in a year. It will supply 80 to 100 meter high towers that are used for today’s multi-megawatt wind turbines.

Eric Smith, CEO of Keystone Tower Systems, states: “We are excited to be moving forward at full speed after securing necessary financing and resources for our factory, including from our existing shareholders. Plus, adding NOV to the team brings complementary skills and experience, especially with their long-standing experience in operating manufacturing facilities and managing in-field operations. The entire team is working together to complete the factory and deliver on our first order efficiently and with the highest quality.”

Clay Williams, Chairman & CEO of NOV, commented: “We believe the combination of Keystone’s technology portfolio and forward-thinking team with NOV’s manufacturing expertise will lead to significant innovation in the wind tower space. We look forward to helping Keystone in their efforts to enable cost-effective wind towers around the world.”

Keystone’s initial focus is on manufacturing the current generation of towers in a stationary factory setting, though the machine will be capable of producing large diameter tall towers 170 m in height or greater. The equipment is designed to be mobile for in-field production of towers at the project site, which significantly lowers the cost of high hub height towers by eliminating transportation constraints.
