The first wind turbine components are arriving in the project area for the 90 turbines being constructed as part of the Glacier Hills Wind Park in Columbia County. Each turbine consists of four tower sections, three blades, a hub and nacelle. The first components to be erected are the bottom two tower sections. Once in place, grouting will be done between the tower and foundation. Next, the top two tower sections will be installed.
Once the tower sections are erected, the nacelle (the enclosure at the top of the tower that contains the generator and transformer), electronic controls and associated equipment will be erected and secured. The nacelle is reached by a ladder that runs inside the tower so technicians can access the turbine components for maintenance and repair. The hub, which is connected to the drive shaft that passes into the nacelle, is then erected, followed by the turbine blades. The blades will be attached to the hub in the air.
When completed, the total height of the turbines, from base to blade tip, will be 410 feet. We expect the first turbines to be operational in August.
Sections for the turbine towers began arriving this week.

they should have checked out VMT first and could have saved some money. Because of VMTs new W-10 transmission, the cost of a tower is reduced by 11% and more electricity is produced, reducing the cost of wind so it is less than coal or nuclear. I found this at www.moongears.com
