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. |

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. |

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. |
