Steam billows from the Fox Energy Center near Kaukauna, Wisconsin, a natural gas-fired power plant that supplies electricity to the region. Operated by Wisconsin Public Service, the facility plays a key role in balancing renewable sources with reliable baseload generation across the state’s power grid.

J. P. Pulliam Generating Station was an electrical power station powered by sub-bituminous coal, which could also be substituted by natural gas. It was located in Green Bay, Wisconsin in Brown County. The plant was named after the former Wisconsin Public Service Corporation president John Page Pulliam (–June 15, 1951). The plant units were connected to the power grid via 138 kV and 69 kV transmission lines. The remaining coal units on site were decommissioned in 2018 leaving only the natural gas fired P31 unit active at the site.
