Pleasant Prairie Power Plant is a base load, coal fired, electrical power station located in Pleasant Prairie, Wisconsin in Kenosha County. In 2009, it was listed as the largest generating station in Wisconsin with a net summer capacity of 1,210 MW and generates roughly 13% of Wisconsin's electricity, burning around 13,000 tons of coal daily. The plant uses experimental technology designed by French Alstom SA to separate carbon dioxide from the exhaust, and is seen as a proving ground for clean coal technology. The plant is owned by We Energies.The 30-year-old power plant has developed and applied a retrofit system that has helped reduce nitrogen oxide by up to 90 percent and sulfur dioxide by up to 95 percent. The Pleasant Prairie plant produces “8.6 million tons of annually – about as much as (that produced by) 1.7 million US cars,” according to the Wall Street JournalIn an effort to reduce carbon dioxide emissions, the plant uses a chilled ammonia process developed by Alstom Power, Inc. that captures up to 90 percent of carbon emissions as it escapes the flue gas. The demonstration project began in March 2008 and will last for two years.In 2009, the America’s Power Factuality Tour stopped at the Pleasant Prairie Power Plant to report on its role in generating electricity in the United States.
