North Fork Ridge Wind Project

The North Fork Ridge Wind Project consisted of 57-2.2 MW Vestas V120 turbines and 12-2 MW Vestas V110 turbines totaling 149 MW of clean energy. The 2.2 MW V120 turbines had hub heights of 122 meters (400 feet) and were some of the tallest turbines erected in North America.  

Mortenson’s scope of work for the project included access roads, public road upgrades, foundations, electrical, towers, O&M building, turbine erection, and tower wiring.  

The electrical scope of the project was comprised of a gen-tie transmission line, 161kV substation, and WTG collection system. The gen-tie transmission line was approximately six miles of 161kV, single circuit, three-phase 795 ACSR on direct-embed galvanized steel monopole structures. The substation included one 161kV main power transformer, which was owner-procured. The collection system was nearly 42 miles with six total circuits of three-phase cabling, operating at 34.5kV and connecting the 69 Vestas wind turbine generators.

All power generated at North Fork Ridge goes directly to Liberty Utilities and replaces the energy generated from one of their coal plants that was retired.
