TYPE OF WIND PROSPECTION Depending on your wind farm project, you may need to measure wind data at 50m, 60m or even 80 m levels in order to properly evaluate the turbine's power production. It is of utter importance to measure wind at the exact hub height in order to maximize development benefits and reduce economical risks. A tilt-up tower with anemometers placed at anticipated turbine hub height is the optimal solution to directly measure the wind speed that a wind farm should experience. This direct method is a lot more efficient than the extrapolation method which consists of using shorter towers with anemometers at two lower heights to extrapolate wind shear. Studies has proven that this method can increase uncertainty of about 1% for every 10 meters, which represents an additional 3% uncertainty for 50 m to 80 m. That is a big deal!

	MEGA LINE - MEGA 80HD Today's wind turbines are higher than ever. As we know, wind speed increases with altitude. Considering that doubling the wind speed generates eight times more power, technology is in constant evolution in order to offer higher energy capture. The common turbine hub height currently installed is in the 80 m range. Aware of the importance of measuring wind at exact hub height, AAT has developed an 80 m tubular tilt-up tower in response to the market's needs. We are the only ones to offer the possibility to obtain wind data at the 80 m level with a low cost tilt-up tower. The MEGA 80HD is the SOLUTION to measure wind at exact hub height and get the most accurate data possible for your project. This new and improved wind assessment technology has the potential to make wind energy easier to estimate and more reliable than ever.
	SCOUT LINE - SCOUT 60 AND SCOUT 50 STANDARD OR UPGRADEABLE The SCOUT line offers the possibility to measure wind at levels as high as 60m and 50m and our SCOUT60UP and SCOUT50UP lines of products allow for an easy upgrade to 80 meters whenever you are ready for the next logical step in your wind assessment campaign . Depending on your project application, the SCOUT tower will be the SOLUTION to measure wind at exact hub height. AAT offers the most robust 60m and 50m towers on the market. They are designed to resist the most difficult conditions. The SCOUT series wind masts, also called anemometer masts, anemometry masts or tilt-up met towers, have the highest ice-rated specifications in their respective categories and can be upgraded to the only true 80 meter tubular tilt-up tower, the MEGA80HD !

SPECIAL APPLICATIONS With all our years of experience in the wind assessment field, we have seen many different wind measurement applications. We have always been able to adapt our products or develop new systems in order to respond to our clients' needs. For example, we have carried out roof type tower installations and designed towers with unconventional heights.  We have also designed a 50 m tower with the MEGA configuration in order to resist very high wind and ice conditions for a client that had a particularly difficult site where no other tower had survived before. We can also modify the anchoring pattern of our towers in order to meet special restrictions, such as available foot print area, soil type and anchor type. We did some special mounting booms designed to install on existing radio towers. These booms needed to be longer and therefore stronger than the conventional ones. The AAT team will be more than happy to be challenged by your special application requirements. Don't hesitate to contact us and submit your specific needs.
