Blattner Energy Announces Post-Tension Concrete Tower Offering
Blattner Energy, a power generation contractor and leading provider of renewable energy construction in North America, today announced that it currently offers post-tension concrete towers that allow for significantly higher hub heights. Tower heights can be increased from an average of 80 meters up to 140 meters, allowing them to reach farther above typical wind speed levels. This results in better energy yields and opens up new areas to wind development that weren’t cost-effective with shorter towers.
The pre-cast, pre-stressed concrete turbine technology is a proven technology that has been used in wind power projects around the world. It provides Blattner Energy customers with a modular tower that can adapt to fit all turbine manufacturers and rotor configurations. Tower sections can be loaded and hauled in legal size on a standard flatbed truck, eliminating the need for escorts and specialized equipment. This technology is the next step in the evolution of wind turbine construction and represents a paradigm shift in the capacity and generation of wind projects.
“From our recent milestone of installing 25,000 megawatts of wind power, to our latest offering of high-performance tower technology, we’re proud to continue leading the North American wind industry,” said Ken Hilgert, business development director of Blattner Energy. “As the demand for wind power grows, our customers can leverage this flexible technology to generate more energy and cost-savings from their projects.”
This concrete tower technology was developed by Postensa Wind Structures SA de CV, a structural engineering and construction company, with more than 60 years of experience in post-tensioned concrete. The technology is exclusively licensed to Blattner Energy.
