The Highland wind farm project, located in O’Brien County, is due to have all 495 MW of its Wind VIII nameplate capacity placed in-service by Dec. 31, 2015.
MidAmerican Energy on March 2 filed with the Iowa Utilities Board an update on its Wind VIII projects. The various Wind VIII sites will host 1,051 MW of new capacity.
Highland is a wind farm acquired from Invenergy LLC. The site interconnects to a 345-kV line at a new substation between the Raun Substation and the Lakefield Junction Substation. Construction activities commenced in fall 2013 and as of the end of 2014, a total of 181 of the 211 wind turbine foundations had been completed. Wind turbine deliveries and erection work will begin in Spring 2015.
In terms of Wind VIII projects already completed:
- Vienna II – In 2013, MidAmerican installed 44.6 MW of wind-powered generation (Vienna II) as part of Wind VIII, which was an expansion of the existing Vienna wind farm site. The 44.6-MW expansion of the Vienna wind farm site in Marshall County has operated as expected since its in-service date of Dec. 4, 2013.
- Lundgren – The Lundgren Site, located in Webster County, is a wind farm acquired from EDF Renewable Development that interconnects to the 345-kV system at the Lehigh Substation that is jointly owned by MidAmerican Energy and several other parties. All 251 MW of the wind farm’s nameplate capacity were placed in-service by Nov. 20, 2014.
- Macksburg – This site is a 119.6 MW wind farm in Madison County acquired from RPM Access LLC. The site interconnects into a 161-kV line at a new substation between the Winterset Junction Substation and Creston Substation via two distinct provisions in the same generator interconnection agreement. All 119.6 MW of the wind farm’s nameplate capacity were placed in-service by Dec. 13, 2014.
- Wellsburg – This site is a 140.8 MW wind farm in Grundy County that was acquired from RPM Access. The project interconnects into the 161-kV system at the Wellsburg Substation owned by ITC-Midwest. All 140.8 MW of the wind farm’s nameplate capacity were placed in-service by Dec. 10, 2014.
Notable is that the 120-MW Scranton sites, located in Greene County, were acquired from Volkswind USA. That wind farm project is no longer being pursued at this time due to certain unspecified environmental concerns at the site.
