Wisconsin Public Service announced plans to double their power output at their Weston Facility. Weston 4 is expected to go online in 2008.
The coal-fired giant will be built next to Weston 3, which was built in 1981.
The new plant comes with a price tag of $700 million, and will produce 500 megawatts of power.
Officials say they went with coal because it is cheaper than natural gas, and since Weston 3 runs on coal, all the facilities for coal are already in place.
WPS will need nearly four million tons of coal per year to fuel the plants.
