Powerspan, FirstEnergy to Receive Grant for
Multi-Pollutant Control Technology

NEW DURHAM, N.H., June 18, 2002—Powerspan Corp., a clean-energy technology company, and FirstEnergy Corp. (NYSE: FE), a registered public utility holding company based in Akron, Ohio, are receiving a $4.5 million grant from the Ohio Coal Development Office (OCDO) for the commercial demonstration of ECO™ (Electro-Catalytic Oxidation) technology. The OCDO, within the Ohio Department of Development, supports the installation of beneficial and promising energy technologies that allow for cleaner and more economical use of Ohio coal.

The grant will support the commercial demonstration of Powerspan's ECO technology at FirstEnergy's R.E. Burger Plant near Shadyside, Ohio. ECO technology is a multi-pollutant control system that removes sulfur dioxide (SO2), nitrogen oxides (NOx), mercury, and fine particulate matter from the flue gas of coal-fired power plants. A pilot unit at the Burger Plant has yielded greater than 95% SO2 removal, 90% NOx removal based on typical inlet NOx conditions, and high removal levels of both mercury and fine particulate matter.

Installation of the 50-megawatt commercial ECO demonstration unit is proceeding at the site, and the unit is scheduled to be operational in the second quarter of 2003. The unit is being installed as a slipstream on a 156-megawatt boiler and is designed to process approximately one-third of the boiler's flue gas. In addition to reducing air emissions, the demonstration unit will produce a marketable fertilizer byproduct.

"We thank our utility partner, FirstEnergy, and the Ohio Coal Development Office for their continued support of this important technology," said Powerspan's President and COO Phillip Boyle. "Our pilot unit is operating well, and we look forward to proving ECO's commercial readiness for full-scale installations."

"We are grateful to the State of Ohio for its support of this promising new technology," said Dan Steen, director of FirstEnergy's Environmental Department. "We believe a multi-pollutant strategy is the best approach to further reducing emissions of sulfur dioxide, nitrogen oxides and mercury nationwide."

Powerspan Corp. is engaged in the development and commercialization of proprietary energy technology for the global electric power industry. Company research and development efforts focus on the application of its technology to reduce the environmental impact of power generation.
