Wind VIII Construction
The Wind VIII project, a 448-turbine, 1,050-megawatt expansion to MidAmerican Energy’s current wind portfolio, comprises
the Highland, Lundgren, Macksburg, Wellsburg and Vienna II wind farms.
The Vienna II project, a 19-turbine expansion of the Vienna wind farm, was placed in-service in December 2013. The following
projects were placed in-service in 2014:
- Lundgren – 107 turbines, 251 megawatts
- Macksburg – 51 turbines, 119.6 megawatts
- Wellsburg – 60 turbines, 140.8 megawatts
The Wind VIII project utilizes Siemens’ 2.3-megawatt wind turbines. All of the blades for the expansion are manufactured
at Siemens’ Fort Madison, Iowa, facility, while the hubs and nacelles are manufactured at Siemens’ Hutchinson, Kan.,
facility. The steel towers are manufactured at various locations in the United States, including Texas, Colorado and
MidAmerican Energy currently owns and operates 1,504 wind turbines representing 2,840 megawatts of wind generation
capacity. When the 211-turbine, 495-megawatt Highland wind project is complete in 2015, MidAmerican Energy will have a
total of 1,715 wind turbines representing 3,335 megawatts of wind generation capacity.
Impact on the Economy
The Wind VIII project will provide more than $3 million in landowner payments each year and more than $360 million
in additional property tax revenues over the next 30 years. The expansion is being constructed at no net cost to the
company’s customers and will help stabilize electric rates over the long term. Approximately 1,000 construction jobs
are being added to Iowa’s economy during the two-year construction period, and approximately 190 new permanent jobs
will have been added when the expansion is complete.
