The Benton County Wind Farm (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. 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.

In August 2006, Duke Energy Indiana finalized its agreement to buy the output of 54 of the wind farm's 87 wind turbines for 20 years. This was the first significant long-term wind power purchase agreement in Indiana. The remaining 33 wind turbines in the wind farm sell their electricity to Duke and Vectren Energy Delivery.

The Benton County Wind Farm developer and owner is Orion Energy LLC, a wholly-owned subsidiary of BP Alternative Energy.

In early 2009, the nearby Fowler Ridge Wind Farm was Indiana's second wind farm to open, and became Indiana's largest wind farm.
