Alstom to supply NID emission control system for the Homer City Generating Station

Alstom, a global leader in power generation technology, today announced the award of a contract in excess of 70 million ($95 million) to supply NID^TM Dry Flue Gas Desulphurization (DFGD) Systems for two 660 MW coal-fired units at the Homer City Generating Station in Indiana County, Pennsylvania. This environmental control project is designed to significantly reduce emissions of sulphur dioxide, mercury and other pollutants.

Alstoms Knoxville, Tennessee-based North American Environmental Control Systems (ECS) team will supply NID^TM system reactors, fabric filters, mixer and hydrators, inlet and outlet plenums, lime storage and feed systems, and activated carbon injection equipment to Kiewit Power Constructors under a Turnkey EPC Agreement for the environmental upgrades. The vast majority of manufacturing activities associated with Alstoms role in the Homer City NID^TM deployment will take place within the United States.

We are grateful for the opportunity to participate in this important step towards lowering the environmental impact of power generation activities at Homer City, said Jim Yann, Managing Director of Alstoms North American Environmental Control Systems business. Alstoms focus with our patented NID^TM technology is to provide customers with a unique cost-effective solution to rapidly ensure compliance with environmental regulations, while also ensuring reliable supplies of electricity and cleaner air for future generations.

Alstoms NID^TM DFGD technology provides a single, easily deployed platform that significantly lowers particulate emissions and provides full compliance with the latest U.S. government environmental regulations. Alstom technology was selected thanks to its lower overall lifecycle evaluated costs and non-financial selection criteria. The NID^TM systems compact modular design offers a convenient retrofit solution for existing power plants and its low installed and operating costs make it an attractive solution for environmental compliance.

Alstom has installed more than 60 NID^TM systems worldwide. The Homer City project represents Alstoms third recent NID project involving pulverized coal boilers in the U.S. The NID^TM unit at NRGs Indian River Unit 4 (400MW) is in the final stages of commissioning, and a second system at Unit 3 of Dominions Brayton Point Plant (630MW) is under construction and scheduled to begin service in early 2013.

The Homer City Generating Station was commissioned in 1969, consists of three 660 MW coal-burning units and provides electricity to 2 million households. Alstom previously supplied Select Catalytic Reduction (SCR) and Wet Flue Gas Desulfurization (WFGD) systems for Unit 3 at the Homer City plant.
