Leeward Renewable Energy ~ Lone Tree Wind Farm
Bureau County, Illinois
The Lone Tree Wind Farm is owned and operated by Leeward Renewable Energy and stretches over 20 square miles in rural Illinois. The Boldt Company provided preconstruction budgeting, permitting, and engineering services along with the procurement and construction of the civil and electrical infrastructure—including the erection of 29 GE 2.8-127 wind turbine generators at 89-meter hub heights and 3 GE 2.3-116 wind turbine generators at 80-meter hub heights. Additional infrastructure development included engineering and construction of public road improvements, turbine access roads and crossings, crane pads and paths, turbine foundations, turbine erection and met tower.
Boldt coordinated engineering and construction planning for the electrical infrastructure which was ultimately constructed under a separate contract between Leeward and Michels Power. That work included installation of the energy collection system, generation tie line, a 2.5-mile 138 kV generation tie line and a 138 kV substation.
Boldt’s work included supporting Leeward’s efforts with Bureau County and their engineer for the upgrade, maintenance, and post-construction repair of their public roads. This is an extremely important effort in all counties across the state of Illinois and critical to maintaining the project schedule.
