Oak Creek Power Plant, also known as South Oak Creek, is a base load, coal- and natural gas-fired, electrical power station located on Lake Michigan in Oak Creek, Wisconsin. The plant is located on over 400 acres (160 ha) of land on the border of Milwaukee and Racine counties. As of 2008, the plant was in the process of a billion dollar expansion. In 2009, it was listed as the third largest generating station in Wisconsin with a net summer capacity of 1,135 MW.[1][2]


In 2005, two 615-megawatt coal-fueled units were constructed just north of the existing Oak Creek facility. Unit 1 began commercial operation on February 2, 2010.[3] with Unit 2 following in 2011.

On February 3, 2009, six contract workers were injured when coal dust ignited in a 65-foot coal dust silo on the power plant site. They had been preparing the structure for repairs when an unknown source ignited coal dust that had accumulated at the top of the silo. All suffered burns.[citation needed]

On October 31, 2011, a bluff area roughly the size of a football field and 200 feet above the level of Lake Michigan eroded, washing mud and debris into Lake Michigan. Close to 100 workers were at the site at the time of the collapse; none were hurt or killed.[citation needed]
