With our short summers here in Vermont, we're superstitious about uttering the "w" word in August. But the truth is that it was winter here not long ago. If you're craving some snowy scenes (or simply want to see cool drone footage), check out this video of our 60m XHD TallTower™ being lifted in the field at the RNRG headquarters.
Despite the maturation and widespread use of Lidars in the wind energy industry, we continue to hear common misconceptions related to the technology. This list contains the 10 most common myths about wind Lidar and the true story behind them.
The nacelle-mounted Wind Iris Lidar is one of the most intriguing new technologies in the wind industry. But what, exactly, can it do?
We have some exciting news: SOH Wind Engineering, LLC (SOH WE) has obtained MEASNET certification for their wind tunnel in Williston, Vermont. Located less than nine miles from our headquarters, this tunnel opened in early 2013 in response to our request for local calibration services.
You know that the profitability of your wind farm depends on the performance of each turbine. Minor errors in yaw misalignment, blade pitch, and tip-speed ratio can affect power output and overall energy production. But how do you know when these issues are lurking on your project site?
Recently, two Renewable NRG Systems employees traveled to Hempstead, N.Y., to install a Wind Iris Lidar on a Northern Power Systems wind turbine. From their post on the small nacelle platform, Evan Osler and Alban Jehu could see planes taking off from JFK Airport just a few miles in the distance.
Renewable NRG Systems tilt-up towers are built to withstand extreme weather conditions, from ice storms, to marine climates, to extreme heat. With proper maintenance, they will stand for many years. Still, they need occasional TLC to sustain top performance.
Do you suspect that you have underperforming wind turbines? Are you familiar with the causes and consequences of yaw misalignment?
KB Energy, owned by Keith and Lois Broyles, is a North American-based company specializing in tilt-up meteorological tower services, including installations, decommissions, refits, and repairs. In total, we have installed over 1,700 towers, including a recently completed installation in Alaska. It was the most difficult—and the most satisfying—installation that we’ve ever done.
We’re excited to announce that WindSensor has released an updated classification report for the WindSensor P2546-OPR class 1 anemometer. Classification is used broadly in the wind industry to formally characterize an anemometer’s operational uncertainty. In other words, it indicates how effectively a sensor measures wind speed.
