The Highland Wind Project is a large wind power project in O'Brien County, Iowa. The 500 MW project was placed online in 2015.
Project
The project is part of $1.9 billion in wind power construction announced by MidAmerican Energy in 2013. The project is the largest in Iowa, as well as the largest single-phase project in the world. Siemens is supplying 218 2.3 MW wind turbines for the project.
The project is located at the southern end of Buffalo Ridge. The proposed Rock Island Clean Line HVDC transmission line would originate just north of the project.
An expansion of the project, formerly known as Highland II was developed by Invenergy. This expansion was purchased by MidAmerican energy and constructed in 2016 as the 250 MW O'Brien Wind Farm. It also lies in O'Brien county, just to the north of the Highland project.
