BLACK & VEATCH'S CT-121 SCRUBBER PROJECT SUCCESSFUL FOR DP&L.

Black & Veatch, Overland Park, Kan. a leading global engineering, consulting and construction company, and Dayton Power & Light Company (DP&L) has announced the successful start-up of the largest CT-121 wet flue gas desulfurization system (scrubber) project in North

America at the DP&L-operated Killen Station. The scrubber was added to Unit 2 at Killen Station, a 615-megawatt (MW) coal-fired plant in Wrightsville, Ohio. The new scrubber system enhances air quality in the region by removing sulphur dioxides (SO2), fine particulates and oxidized mercury emissions. The scrubber system process removes guaranteed levels of SO2 emissions, while consuming less power than standard removal processes.

"This is a milestone project that demonstrates DP&L's commitment to providing an environmentally friendly solution, while effectively meeting its customers' electric needs," said Mike Perry, executive vice president of Black & Veatch. "This innovative scrubber system is the most advanced, reliable and cost-effective technology worldwide." The Killen scrubber system was engineered, constructed and commissioned through a collaborative effort between Black & Veatch and DP&L. The project began in 2004.

Black & Veatch is currently working with DP&L to complete construction of similar scrubber systems at the DP&L-operated 2,388-MW, four-unit, J.M. Stuart Station in Aberdeen, Ohio. Completion of the final unit is scheduled in 2008.

Black & Veatch is installing CT-121 scrubber systems in utility facilities worldwide that generate a total of approximately 9,900 MW. The CT-121 process, developed by Chiyoda Corporation, provides superior SO2 and particulate removal from flue gas with low operating costs for all fuel choices and operating levels. Black & Veatch is the sole licensee in North America for this proprietary Chiyoda technology.
