E.ON U.S. is taking steps to reduce its impact on the environment by investing more than $2.3 billion in additional emission controls to reduce the environmental impact of our power plants and create cleaner and more efficient generation for our customers.

These new improvements include:

• $1.1 billion for new sulfur dioxide (SO₂) removal equipment (scrubbers) at KU's Brown and Ghent plants;
• $76 million in upgrades for LG&E's Ohio Falls hydroelectric facility;
• a $1.2 billion state-of-the-art generator addition at the company's Trimble County Generating Station.

Since 1990, E.ON U.S. has spent more than a half billion dollars for SO₂ and nitrogen oxide (NOx) controls. The environmental impact of these investments has been significant. We've reduced SO₂ emissions by 60 percent and summertime NOx by 65 percent, while increasing electric generation by nearly 50 percent.

The Positive Impact of Our Environmental Controls

E.ON U.S. is setting the standard for emission controls within the power industry. Since 2000, the company's Selective Catalytic Reduction (SCR) technology has reduced NOx emissions from 23,000 tons to 2,300 tons, and the emission rate has dropped from approximately 0.40 lb/mmBtu to 0.04 lb/mmBtu. SCRs separate NOx into environmentally benign nitrogen and water.

Overall, LG&E and KU's SCRs finished the 2005 ozone season as the lowest emitting combined units in the U.S. Three of the SCR units are among the lowest four in the U.S., and all six SCRs are among the nation's 17 lowest-emitting units. All six LG&E and KU SCR units operated above 90 percent NOx removal efficiency during the 2005 ozone season.

Pressing Forward

Our past accomplishments have substantially benefited the environment — and it's a legacy we're very proud of — but we continue to press on toward even greater achievements. In the next six years, E.ON U.S. plans to spend more than $800 million on emission-control projects to install more scrubbers and SCR equipment, and other environmental improvements to existing equipment.

While the nation debates global climate change issues, E.ON U.S. will continue to advance clean coal technology through research partnerships, educating customers about responsible energy use. We support our customers' efforts to manage their own energy use by offering a variety of demand-side management programs and finding ways to make direct and indirect reductions in our own operations.
