Building next-generation towers for the next generation of wind power
We make wind energy the lowest cost power source available, not just in the open plains, but throughout the world.
Our spiral-welding technology is a breakthrough in tower manufacturing, making it possible to support larger next- generation turbines.
We can dramatically drop the cost of onshore and offshore towers, and enable turbines to reach higher into stronger winds, for greater energy capture.
Keystone Solutions
onshore towers
Faster than standard tower factories
Drop-in replacement for current tower designs with no change in turbine or project design
Automation and advanced manufacturing give spiral towers a strong cost advantage while improving quality and consistency.
on-site fabrication
2x taller than conventional towers
Bringing tower production to the project site eliminates transport constraints, enabling towers to scale to any size.
Tall towers position turbines to reach stronger winds, making low-cost wind energy available in many new regions.
offshore towers
50% of the footprint of other offshore factories
The offshore industry is growing quickly and requires a massive supply chain build out.
The high speed and small footprint of spiral welding make it ideally suited for port-side manufacturing.

TECHNOLOGY
SPIRAL WELDING
Keystone can manufacture the lightest, lowest cost, and most structurally-optimized towers in the industry.
Spiral welding combines all of the production steps for making large diameter steel towers into one process, greatly reducing the cost, footprint and time required to produce steel shells.
