For Release: 05/07/2012
Green Bay, WI – Wisconsin Public Service Corporation (WPS), a subsidiary of Integrys Energy Group (NYSE: TEG) today filed for a Certificate of Authority (CA) from the PSCW to install Regenerative Activated Coke Technology (ReACT™) at its approximately 321-megawatt Weston 3 plant. ReACT™ is an integrated multi-pollutant control technology that removes SO2, NOx and mercury from coal-fired plants by adsorption with activated coke to attain emission levels found at the best controlled coal-fired plants. WPS said it expects that, based on historical data, the estimated $250 million project will reduce plant SO2 emissions by more than 90%, mercury by 90% or more, and NOx by more than 20%.
"We've decided to upgrade Weston 3 (W3) to ensure its viability as an electric generator in a climate of future uncertainty regarding environmental regulations," said Howard Giesler, Weston General Manager. "Adding this new, but proven, technology will position the unit to be in compliance with future EPA regulations, while enabling the production of safe, clean, reliable and economical electricity."
According to a WPS spokesperson, this new technology simultaneously controls multiple pollutants using only a fraction of the water that conventional wet scrubbers demand, while producing a saleable sulfuric acid by-product commonly used in the fertilizer, paper-making, and many other industries. A recent license agreement brings this technology to North America. WPS has partnered with Hamon Research-Cottrell, Inc. (HRC) to provide the ReACT™ technology, engineering, erection, and other services for the project. HRC holds the license for the ReACT™ technology and provides innovative clean air technologies to a wide array of industries including power generation.
"We are grateful to partner with WPS to bring this proven state-of-the-art, multi-pollutant control technology to North America. The innovation WPS has shown in choosing this technology ensuring we maintain our world leadership in clean coal implementation should be applauded by all in the industry" said Bill Dillon, CEO of Hamon Corporation.
The ReACT™ installation will be the first commercial application of this technology in the United States, although it has been used successfully in Japan for many years and has been successfully demonstrated in the U.S. over a period of five months as part of an Electric Power Research Institute project hosted by Sierra Pacific Power at its North Valmy Station.
Following PSCW approval, the project will take more than 3.5 years to complete and bring more than 200 temporary high-paying construction jobs to the Wausau, WI area.
