Emissions to be reduced by more than 90 percent, improving air quality
ST. PETERSBURG, Fla. (May 25, 2010) – Cleaner air and fewer emissions are the result of Progress Energy Florida’s recently completed clean-air improvements to the Crystal River Energy Complex. The company’s Crystal River Units 4 and 5 in Citrus County (photo available) are now among the cleanest coal-burning plants in the country.
Continuing the company’s commitment to improving air quality, a selective catalytic reduction (SCR) system and scrubber began operating at the Crystal River Energy Complex on Unit 4 this week. The utility’s first clean air scrubber began operating in December and the first SCR began operating in June 2009, both on Unit 5.
“The Crystal River clean air project is a significant, enduring commitment to the environment and the communities we serve,” said Vincent Dolan, Progress Energy Florida president and CEO. “Our Crystal River complex is an industry leader in using start-of-the-art technologies to control emissions. We’re proud of our cost-effective and environmentally-sound solutions to meet the energy needs of all the communities we serve.”
Equipment testing is scheduled to continue over the next several weeks. When the testing is complete, nitrogen oxides (NOx) and sulfur dioxide (SO2) emissions at the Crystal River Energy Complex Units 4 and 5 are expected to be reduced by approximately 93 percent and 97 percent, respectively, as compared to 2008 levels. Mercury emissions are expected to be reduced by 80 percent as well.
The selective catalytic reduction technology installed at the plant converts nitrogen oxides (NOx) to nitrogen and water through a chemical reaction with ammonia - similar to a car’s catalytic converter - then moves it into the precipitator on its way to the scrubber.
The “scrubbers,” or flue-gas desulfurization units, remove sulfur dioxide (SO2) emissions by taking the gas produced from burning coal to generate electricity and passing it through a tower in which a water and limestone mixture is sprayed. The SO2 in the flue gas reacts with the limestone to produce gypsum, and the remaining water vapor rises through the stack.
The $1.4 billion environmental investment in Crystal River Units 4 and 5 will allow the company to purchase less-expensive coal in addition to significantly reducing plant emissions. These improvements will generate significant fuel savings, including a projected fuel savings of up to $10 million in 2010 and additional fuel saving in future years.
The Crystal River Energy Complex, which includes four coal-fired units and one nuclear unit, is one of the largest generating facilities in the country. Located near Crystal River, Fla., the complex is capable of producing
3,148 megawatts (MW) and serves the daily needs of more than half of the utility's more than 1.6 million customers.
Progress Energy Florida, a subsidiary of Progress Energy (NYSE: PGN), provides electricity and related services to more than 1.6 million customers in Florida. The company is headquartered in St. Petersburg, Fla., and serves a territory encompassing more than 20,000 square miles, including the cities of St. Petersburg and Clearwater, as well as the Central Florida area surrounding Orlando. Progress Energy Florida is pursuing a balanced approach to meeting the future energy needs of the region.
