On 7/27 I met up with a guy over at the gravel pit who drives the pick-up at the back of the trailer carrying the blade or other component for the wind turbines. He was a wealth of information. He actually steers the back wheels of the trailer to make the turns. He said there are 4 tower sections and that the blades attach to the nacelle which attaches to the hub. From the numbers he gave me, whole assembly weighs about 350 tons. Whoops, forgot to add the weight of 3 blades which is an additional 200 + tons, bringing the total to over 550 tons!
I decided to check out the wind turbine construction off New Galen road today. Two turbines are planned at the top of a new road they built off of New Galen. I biked up that new road which was very bumpy and difficult to bike. It looks as if they have all of the parts for the two turbines at the site. I took a few photos showing everything. I thought it would be too dangerous to bike down the gravel road, so I walked the bike down. I had to zig-zag down because my bike is very heavy and it wanted to charge down the hill by itself!
I also checked the construction site off Wager road. The only progress there is the base – no parts are on site. I got a report that the base is the top of a large cone of concrete set deep in the earth. I don’t have a photo of that – got there too late – they had already filled in around the cone.
Here is a map of Phase I of the turbine installations: You can see the towers for the two units off New Galen road easily from Rte. 121.

This photo and the next are not from the current construction site, but they show a typical foundation for the round pad shown below.
Part of the tower – again the bike is for size perspective
This is the top nacelle that the blades attach to. The nacelle attaches to the hub, which attaches to the tower.
This is the hub which the nacelle attaches to and which attaches at the top of the tower
Two photos of the blades. Note the elaborate tie-downs so that the wind doesn’t move them before they are put up. The blades are 57 meters or 187 feet long and are made in Andover NY (south of Hornell on Rte. 417)
I’m still amazed that they can put these things high up in the air and attach them with bolts. Riggers have a rare expertise!
This photo is also not from the current construction site, but this and the next one show how the top sections are attached.
