TheHighland Wind Energy Center is a 501.4 megawatt (MW)wind farm inO'Brien County, Iowa. It became the largest facility in the state when it was placed online in 2015.
The facility is part of $1.9 billion in wind power project announced byMidAmerican Energy in 2013. It was the largest project in the world to be built in a single construction phase. Siemens supplied 218 2.3 MWwind turbines for the facility.[1]
The facility is located at the southern end ofBuffalo Ridge. TheRock Island Clean LineHVDC transmission line was proposed to originate just north of the project.[2]
An expansion of the project, formerly known as Highland II was developed byInvenergy.[3] 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.[4]
