Concrete Wind Tower Prototype

The Adam’s County Concrete Wind Tower Prototype is the largest landbased wind turbine ever built in the United States. At 379 feet from ground to hub, the concrete turbine is over 100 feet taller than neighboring steelconstructed turbines. This prototype 2.415-megawatt concrete turbine enables MidAmerican Energy to evaluate the amount of additional wind energy that can be generated at higher altitudes. Construction of the tower began in August 2015 and proved to be an entirely different process than constructing a steel tower turbine. Instead of manufacturing tower sections in a factory and transporting them, crews poured the concrete in segments to erect the tower onsite. [Read More]

Siemens Introduces Concrete Tower Technology to Reduce Energy Costs

Siemens has announced the commercial launch of a concrete wind turbine tower technology that places turbines in stronger winds at higher altitudes – resulting in more potential energy production and increased project revenue for customers. This technology is part of an ongoing commitment to using innovation to expand wind power in the United States and around the globe.

Siemens partnered with Wind Tower Technologies of Boulder, CO, for engineering and construction methodologies. A unique feature of this patented tower system is the on-site match casting of annular precast tower segments, eliminating the need to grout the joints or provide other special surface treatments between tower sections.
