| General | 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. |

| News | December 15, 2016 - Tampa Electric reported that it inadvertently released 14 tons of sulfur dioxide into the atmosphere Thursday as a result of a malfunction at its Polk Power Station. The gas was released for about six hours through its flare system at the combined-cycle, coal gasification power plant near Mulberry. The plant converts coal into a gas to remove sulfur content from the resulting synthetic gas fuel. The flare burns off excess gas while the plant is starting. Valves inside the plant were not operating correctly, causing the unplanned release of sulfur dioxide into the atmosphere through the flare, the utility reported. The utility is permitted to release the gas as part of its normal startup operations for up to two hours within a 24-hour period, Tampa Electric spokeswoman Cherie Jacobs said. Engineers at the utility determined the event had a "low risk potential" for public health, safety and welfare. Since the release lasted longer than permitted, the utility was required to notify state, county and local officials, residents and the news media under a regulation created by Gov. Rick Scott. The rule came after two major spills earlier this year: a sinkhole opening up under a Mosaic gypsum stack spilling acidic wastewater into the Floridan Aquifer and St. Petersburg releasing millions of gallons of sewage into Tampa Bay. | |
