AES To Invest $50 Million in Advanced Clean-Coal Emissions Control Technology

The AES Corporation announced today that AES Westover, a 126 MW coal-fired facility near Binghamton, NY, will begin installation of state-of-the-art multi-emissions control technology on its 84 MW Unit #8 in early 2007. AES will invest $50 million in the project, which is expected to be completed by the end of 2008.

The project will increase AES Westover's removal rates for NO(X) emissions from 60% today to 90% once the project is complete, through the use of a Selective Catalytic Reduction (SCR) system with ammonia injection. SO(2) emissions will be reduced by 95% through the use of a dry scrubber, followed by a fabric filter bag-house-a final stage in the emission control process. In addition, the combination of these technologies is also expected to reduce mercury emissions by 90%.

"AES has the cleanest coal operating fleet in New York and this project demonstrates our ongoing commitment to improving the air quality in the state. Each of AES's coal-fired plants in New York continue to emit significantly less SO(2) and NO(x) than any other coal-fired facility in the state, based on EPA data," said Jim Mulligan, Plant Manager at AES Westover. "This technology will allow AES Westover to meet all of the requirements under the Clean Air Act while continuing to meet increasing demands for energy in New York."

AES has committed more than $150 million to emissions control projects in upstate New York since 1999. In a similar approach to the AES Westover project, AES Greenidge, located in Dresden, NY, announced in July this year that it is testing a multi-pollution control technology as part of a demonstration project with the US Department of Energy. Since 1999, AES has reduced SO(2)and NO(x)emissions by 70% at its AES Somerset and AES Cayuga facilities in New York State, and has reduced mercury emissions at both plants by more than 90%. Today, these facilities are equipped with enhanced, state-of-the-art multi-pollutant emission control equipment including Flue Gas Desulfurization (FGD) and Selective Catalytic Reduction (SCR) technology.

"AES has consistently demonstrated its commitment to supporting the environment in New York," said Pete Norgeot, Vice President, AES Eastern Energy. "The AES Westover project will continue to help New York State meet its energy, environmental and economic development goals."

Babcock Power Environmental will engineer and supply the equipment and Nicholsen & Hall will construct the AES Westover project.
