WindPole has developed a boom that extends beyond the wind shadow of its towers.
WindPole has developed a 20’ boom that facilitates bankable data collection from narrow-faced broadcast towers at hub height. Supported laterally with a tie-back assembly and vertically with a guy line, WindPole’s booms securely hold sensors 20’ from the tower. The design was guided by Annex G of the IEC 61400-12-1 and each installation is verified by independent wind analysts.
Booms are designed to survive 94 mph wind with no ice load, and 81 mph wind with 1.0” radial ice. They were designed to mitigate the vibrations that can degrade cup anemometers which reduces uncertainty to data sets.
At right, the six booms are mounted at three elevations on a 120 meter tower will provide wind data from the full blade sweep of a wind turbine.

The booms on this tower are at 40, 65 and 80 meters and extend 20 feet from the tower face. This configuration captures 50% of the vertical blade-sweep to help accurately assess a site’s wind resources.
WindPole booms and mounts are manufactured in the U.S. and local tower climbers are hired for each installation.
WindPole de-risks wind project finance and accelerates grid integration for top wind developers, government, ISO/RTO, project operators and industry analysts. WindPole provides real time, hub-height wind resource data from a network of very tall (80+ meter) towers.
