AEP Invests in Emissions Control Company

LCG, July 25, 2000--American Electric Power Co. Inc. said yesterday it has invested in Powerspan Corp., a privately held company that is developing environmental controls for coal-fired power plants.

AEP has plenty of coal-fired power plants. Most of its 38,000 megawatts of generating capacity comes from coal-burners.

Powerspan, a New Hampshire company, has reported that its catalytic converter systems have produced significant reductions in most emissions, including nitrogen oxides, sulfur dioxide, particulate matter, mercury and other emissions.

"This is a strategic investment for AEP in the development of new emissions control technology that goes well beyond what's available for coal-fired power plants today," said Marty Mearhoff, AEP'svice president for renewable energy and advanced technologies.

AEPs investment in Powerspan, made through its AEP Pro Serv Inc. subsidiary, was enough to land Mearhoff a seat on the Powerspan board.

AEP said its investment, along with those of others, will be used to accelerate product development and commercialization of Powerspans proprietary catalytic converter method of emissions reduction, which "provides the functionality of four separate control technologies into a single integrated system and produces valuable byproducts that become the feedstock for other industrial processes."

In a separate news release, Powerspan said its equipment not only gets the offending materials out of a power plants emissions, it saves them so they can be used to produce concentrated acids, gypsum for making drywall, fertilizer and other products.
