Wisconsin Public Service vies to be first in U.S. to use ReACT

Wisconsin Public Service Corp. (WPS), a subsidiary of Integrys Energy Group (NYSE: TEG), has filed for a Certificate of Authority from the Public Service Commission of Wisconsin (PSCW) to install the first U.S. commercial application of Regenerative Activated Coke Technology (ReACT) at its 321 MW Weston 3 plant.

ReACT is a multi-pollutant control technology that removes sulfur dioxide (SO2), nitrogen oxides (NOx) and mercury from coal-fired plants by adsorption with activated coke. WPS said it expects that the estimated $250 million project will reduce plant SO2 emissions by more than 90 percent, mercury by 90 percent or more, and NOx by more than 20 percent.

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.

The ReACT technology has been used successfully in Japan for many years and has been successfully demonstrated in the U.S. 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 construction jobs to the Wausau, Wisc. area.
