A state-of-the-art integrated coal gasification combined-cycle (IGCC) power plant, Tampa Electric’s Polk Power Station produces enough electricity to serve 75,000 homes.  The coal gasification unit provides clean, coal-fueled power, with a minimum removal of 95 percent of the sulfur from the coal gas. This exceeds the performance of today's most advanced coal-fired generating units. Furthermore, nitrogen oxides emissions are also lower than many of today’s most advanced coal-fired generating units. The sulfuric acid and solid byproducts are then sold for industry use.
