With towers reaching 105 meters high, the Snyder Wind Energy Project’s wind turbines are the tallest in the United States to date. The project comprises 21 Vestas V90 3.0-megawatt wind turbines. The Snyder project will produce energy sufficient to power more than 12,000 average homes annually. Earth Systems provided engineering design support for the Patrick and Henderson tensionless pier foundations, which extended 40-feet deep into hard clay and sandstone, using an Anderson Drilling “Big Stan” 18-foot diameter auger rig.
