Turbine height compared to the Nebraska State Capital building
Wind turbine specifications
Site information
Each wind turbine sits on approximately one-quarter of an acre. Furthermore, the wind power project features a land lease agreement that was signed with a local cattle rancher who continues to graze livestock right up to the base of the machines. The rancher supplements his current income with long-term annual land lease payments.
The turbine manufacturer and installer, NEG Micon, strives to ease its footprint on the environment by using as little land as possible and encouraging multi-use of the land around the machines.

Annual production statistics
The project produced 29,263,232 kilowatt-hours (kwh) in full-scale operation, from Oct. 1, 2002, to Sept. 30, 2003. That amount equals a 32 percent capacity factor, or 32 percent of full-load operating capability.

Manufacturing
All operation and maintenance of the wind turbines is monitored by the WindMan Server Solution™ SCADA system from NEG Micon Control Systems.
NEG Micon installed the SCADA server system inside the tower base of one of the turbines to minimize the capital costs of the wind-power project.
The system enables in-depth collection, analysis and storage of operating data. The plant operators, both on- and off-site, can use WindMan to continuously monitor the machines to ensure their maximum power generation. Additionally, the wind project can be monitored in real time from NEG Micon's service centers in Cheyenne, Wyo., and Champaign, Ill.
