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 (1.6 km2) 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]



Two 615-megawatt coal-fueled units are under construction just north of the existing facility. Construction started June 29, 2005, Unit 1 is planned to begin operations in 2009 with Unit 2 following in 2010. Bechtel Power Corporation is the prime contractor for engineering, procurement, and construction (EPC) of the facility. The two steam turbines were provided by Hitachi.

Concrete was poured 24 hours a day for 41 days to construct the 550-foot (170 m) tall 70-foot (21 m) diameter common chimney for the expansion project.

The expansion project may be known as the Elm Road Generating Station, though it is on the same property as the Oak Creek Power Plant. Elm Road Unit one entered commercial service on February 2, 2010.[3]

On 03 February, 2009, 6 contract workers were injured when coal dust ignited in a 65 foot coal dust silo on the power plant site. The 6 workers (4 inside and 2 outside) were preparing the structure for repairs when an unknown ignition source ignited coal dust that had accumulated at the top of the silo. All 6 were transported to local hospitals with varying degrees of burns, with the most severe being third degree burns to hands and face.

On 31 October, 2011, a bluff area roughly the size of a football field and 200 feet above the level of Lake Michigan eroded under unknown circumstances washing a large amount of mud and debris into Lake Michigan. The area that washed away was near the construction site of a new air quality control unit for the plant. Close to 100 workers were at the site at the time of the collapse of which none were hurt or killed. Among the debris that was washed into Lake Michigan included several storage trailers, a pickup truck, and a temporary storage building being use for the construction. The area was also a former site where coal ash was stored and it is believed that coal ash washed into Lake Michigan as well. WE Energies Contracted with Clean Harbors to prevent further environmental damage and clean the area up.
