KEYSTONE

When we invested in Keystone Tower Systems back in 2017, the technology was largely unproven with only a small scale pilot line installed to demonstrate the concept. By supporting the upscaling and further roll-out we showed our confi dence in the potential of spiral welding technology to fully automate wind turbine tower production and we helped paving the way for in-fi eld manufacturing. The potential for signifi cant reductions in the cost of wind energy as well as on site manufacturing of larger size towers will shake up the whole wind energy supply chain in the years to come, both onshore and offshore. The technology match with our partners ArcelorMittaI (supply of the key raw materials) and OCAS (providing welding expertise) could not be better.
