The Mount Storm Wind Project (Phase I 100 MW, Phase II 164 MW) was constructed along 12 miles of the high Allegheny Mountain ridges in West Virginia. Mount storm brings 264 MW of clean energy to the mid-Atlantic power grid.
Mortenson’s scope of work on Phase I included design and construction of 17 miles of access roads, 82 turbine foundations, erection of 82 Gamesa G80 2-megawatt wind turbines on 78-meter towers, installation of 4.7 miles of 34.5kV underground electrical collection system and two meteorological towers.
Phase II included design and construction of 7.7 miles of access roads, 50 turbine foundations, erection of 50 Gamesa G80 2-megawatt wind turbines on 78-meter towers and installation of 20.9 miles of 34.5kV underground electrical collection system.
Unique to this project was the use of dynamic compaction to densify soils to the depth of about 20 feet. 10,000 tons of limestone dust was added to the fill area to neutralize the acidic soil.
