AEP NOx Emissions Reduced 70%

American Electric Power (NYSE: AEP - News), the nations largest generator of electricity, reported that its nitrogen oxides (NOx) emissions had been reduced by 70%, from 145,762 tons during the 2000 ozone season to 45,945 tons during the 2005 ozone season from May 1 to Sept. 30, while generating 5% more electricity.  Smog, is formed from NOx and volatile organic compounds (VOCs) in the presence of sunlight and heat. 

The NOx reduction was made possible by installing selective catalytic reduction (SCR) equipment on 14 of its 50 generating units. AEP's SCR systems are designed to reduce NOx emissions by up to 90 percent; however, a majority of AEP's SCR units achieve better than design and industry standards by consistently achieving NOx reductions of 92 to 94 percent.

"AEP has invested nearly $1.3 billion in equipment retrofits to reduce NOx emissions at our plants." said Michael G. Morris, AEP chairman, president and chief executive officer.  "As we move forward with an additional $4 billion in pollution control equipment retrofits before 2010, the excellent performance of this equipment demonstrates that we have the technological expertise to make our emissions reduction equipment work as well, and often better, than designed to improve the environmental performance of our very low-cost coal-fired power plants," Morris said.

AEP also has made significant investment to reduce SO2 emissions, including installation of flue-gas desulfurization systems, commonly called scrubbers, on eight units. After already spending more than $1 billion to reduce SO2 emissions since the mid-1990s, AEP will invest another $3.3 billion before 2010 to make even deeper cuts in SO2 emissions. AEP will install scrubbers on an additional 14 generating units by 2010.

In addition to its retrofit program to reduce NOx, sulfur dioxide (SO2) and mercury emissions on its current generating fleet, AEP also has committed to build the first large-scale, base-load Integrated Gasification Combined Cycle (IGCC) clean-coal generating plant as soon as 2010. IGCC technology converts coal into a synthetic gas before it is burned. The process results in fewer emissions, and carbon capture and sequestration is expected to be easier from an IGCC plant than from a pulverized coal plant. AEP has filed for cost recovery for the first ~600MW plant to be built in Meigs County, Ohio and on September 29 announced that they had hired GE and Bechtel to do the front end engineering on the plant, to be completed in 10 to 12 months.  Information on how a IGCC plant operates can be found in this previous post.

American Electric Power, based in Columbus, Ohio owns more than 36,000 megawatts of generating capacity, 3.4% of the U.S. capacity and is the nation's largest electricity generator. AEP is also one of the largest electric utilities in the United States, with more than 5 million customers linked to AEP's 11-state electricity transmission and distribution grid.

Well that is good news. Nice to see that they are investing some serious dough in pollution abatement and they are going ahead with an IGCC plant instead of adopting the all-to-common 'let's wait and see what we learn from FutureGen' stance that most energy companies have adopted.

Thank you for good information that you share with us.It is very good news.If who have other information about NOx Emissions or about interest global warming ,please send email to me for sharing useful information.

Thank you so much.
