RockGen Energy Center

Banner Image

The RockGen Energy Center is located in the town of Christiana in Dane County, Wisconsin.  Three combustion turbines produce electricity during times of peak demand.  The RockGen Energy Center is the largest peaking plant in the state of Wisconsin.  At the time it was constructed, it was the largest plant in Wisconsin using clean-burning natural gas.

The RockGen Energy Center provides electricity to the Wisconsin wholesale power market.

The Wisconsin power market is primarily made up of old, coal-fired power plants.  The demands of the Clean Air Act and other environmental issues related to coal-fired generation are forcing suppliers to shift to cleaner energy resources.  Calpine’s RockGen facility provides Wisconsin with environmentally responsible energy to help meet the state’s growing demand for electricity, while also providing needed diversification for the fuel mix.
