In response to industry demand to measure the wind at greater heights, NRG Systems now offers an 80-meter tilt-up tower. Built on the same platform as the company’s 60-m XHD system, the taller model uses bolted joints for a stiffer, stronger tower, while offering familiar installation and performance.
The drive for data accuracy has led many developers and consultants to measure directly at turbine hub heights. “Erecting one or several 80-m systems into a wind resource assessment has proven to reduce uncertainty and help developers negotiate more favorable financing and power purchase agreements,” says Barton Merle-Smith, director of marketing and sales for NRG Systems.
“In the U.S. and Europe, the best on-shore wind sites have already been developed,” says Merle-Smith. “The industry has become more sophisticated and disciplined in its approach to resource assessment in an effort to minimize uncertainty. Measuring directly at 80 m helps make this possible.”
The complete 80-m XHD tower includes a galvanized 10-in diameter tilt-up tower with a steel baseplate, a SymphoniePLUS 15-channel data logger, company sensors to measure wind speed and direction, side-mount booms, and other accessories. The high-visibility package, required by the FAA in the U.S., includes an orange-and-white painted tower, a compliant lighting system, and marker balls.
“Strength and ease-of-use were primary company drivers when developing the new system,” said Owen Clay, director of engineering for NRG Systems. “We took care to meet the highest standards for strength and durability, while preserving the simplicity of installation and maintenance.” The 80-m XHD system ships by surface freight free of charge in its Enivocrate packaging.
