The Benton County Wind Farm (also called Goodland I) consists of 87 model sl/sle Gen4 GE 1.5 MW wind turbines near Earl Park, Indiana in northern Benton County, Indiana. The farm's nameplate capacity is 130.5 MW. The farm was developed by Orion Energy Group, LLC (Oakland, CA) and Vision Energy, LLC (Cincinnati, OH) beginning in 2003. It began commercial operation in April 2008. At the time of its construction, it was Indiana's only commercial-scale wind farm. Duke Energy purchases electricity from the wind farm and sells it to customers through its GoGreen program.
